CHAPTER 2: OVERVIEW

The Emerald® system provides users with a seamless desktop experience anywhere on a TCP/IP network, while allowing the actual hardware to be securely housed in a corporate data center or in the cloud. Emerald enables the same high fidelity experience of a
desktop PC even for media-rich applications, for example, watching videos, photo editing with Photoshop or 3D design with AutoCAD. The remote desktops may be hosted on a physical PC / workstation or may be a virtual desktop hosted on a private server or in the cloud. The Emerald system provides its users with Receivers that communicate with target computer nodes (whether physical PC or virtual desktop) over a standard TCP/IP network. Physical PCs/Workstations/Servers have an Emerald SE or PE Transmitter unit or Emerald ZeroU DVI or DisplayPort Transmitter unit physically connected to provide communication over the TCP/IP network. The performance of Emerald allows them to be deployed on standard corporate networks and even across Wide-Area- Networks (WANs).
Desktop users can access remote keyboard, mouse, video, audio, USB mass storage devices, headsets and other USB devices from the Receiver unit to the remote PC/workstations or Virtual Desktop via the Emerald system.
NOTE: Not all USB 2.0 devices are supported depending on how they negotiate/communicate with the host. If you find your USB 2.0 device isn’t working properly, please report these devices to Black Box.
NOTE: References to the Emerald system in this document refer to both Receivers (EMD2000PE-R, EMD2000SE-R, EMD2002PE-R,
EMD2000PE-R-P, EMD2002PE-R-P, EMD2002SE-R ) and Transmitters (EMD200DV-T, EMD2000PE-DP-T, EMD2000PE-T,
EMD2000SE-DP-T, EMD2000SE-T, EMD2002PE-DP-T, EMD2002PE-T, EMD2002SE-DP-T, EMD2002SE-T). The Emerald ZeroU DVI or DisplayPort Transmitter (EMD200DP-T, EMD200DV-T) can be used in place of the SE Transmitter where rack space is limited, but these devices cannot support USB-redirection.

2.1 EMERALD SYSTEM FEATURES
Emerald leverages state-of-the-art technologies in compression, networking, and latency management. Some of the key features of Emerald are:

• Pixel-Perfect Video Quality: The Emerald system uses a compound compression algorithm to provide a lossless video experience at a low network bandwidth. None of the bandwidth variability and noise effects of analog extension schemes exist.
• Uses Unicast stream for shared mode to allow scaling of # of users that can share a transmitter. Analog audio can now be shared in a shared mode connection.
• Seamless integration of Physical and Virtual Desktops: The Emerald system connects to physical PCs, servers, and video sources as well as virtual desktops hosted on servers or in the cloud. This allows seamless connection to physical resources and virtual resources from the same Receiver unit. IT professionals use this capability to optimize their deployments and migrations to cloud services.
• High Reliability and Highly Secure: The Emerald system minimizes maintenance for administrators. The intuitive On-ScreenDisplay is simple to learn and understand. The individual units have no moving parts to minimize potential for hardware failures. All media streams transmitted between the Emerald devices are encrypted using 128-bit SSL. Password protection is also provided to control access to all administration functions.
• Environmentally Optimized: The Emerald system is optimized to minimize power requirements and eliminate noise. All Receivers and Transmitters consume less than 6 Watts and are completely silent.
• Easy Deployment: The Emerald system is designed to be easily and quickly deployed. No new drivers or software need to be installed on target PCs or Virtual Desktops. The system uses standard networking protocols and cabling. Users and connections are defined using an intuitive On-Screen-Display (OSD). Connections can be made via simple “click on target.” Multiple modes of operation such as private connections, shared connections, auto-login, and auto-connect enable various workflows and collaborations to be supported. Analog audio can now be shared in a shared mode connection.
• The Emerald ZeroU DVI or DisplayPort Transmitter features a small form factor to use zero rack space—you save money when rack space is expensive. This Transmitter can be powered over USB or via an optional power supply.

2.2 OVERVIEW OF EMERALD DEVICES

NOTE: Serial Port is not supported yet to pass RS-232 data between TX and RX. A USB Serial Converter must be used with USB-Redirection.

Some of the key capabilities and operation of Emerald devices are described next. These capabilities are supported across all Emerald devices.

2.2.1 VIDEO
The Emerald® system supports 24-bit color depth digital video up to a maximum resolution of 1920 x 1200 at 60 Hz for any video head on both Transmitter and Receiver. One or two DVI-I connectors is provided on the Receiver or Transmitter for cable
compatibility, but only digital video is supported. See Appendix 1 – Emerald Video Resolutions Supported for the list of resolutions currently supported by Emerald. VGA or Analog video can be supported by using the KVGA-DVID VGA to DVI-D converter but should only be used with Single Head transmitters because of the dithering options. If used with a Dual-Head transmitter, the video quality will not be as good as it is with the Single Head model.

2.2.2 AUDIO
The Emerald system supports CD-quality stereo audio from the remote workstation (with the Transmitter connected) or virtual desktop to peripheral speakers connected to the USB connector on the Emerald Receiver. The Emerald Transmitter uses its USB
interface to capture audio from the remote workstation. This increases audio quality by eliminating analog audio noise issues and removing the need for a sound card in PC/Workstation.
The Emerald Receiver connects audio from a peripheral microphone connected via the USB connector on the Receiver to the remote workstation or a virtual desktop. The Emerald Transmitter uses USB to supply the microphone data to the remote workstation. Higher quality audio can be obtained using USB re- direction for USB headsets or speakers.
The Emerald ZeroU DVI Transmitter has just one audio connector (used to connect speakers). The Emerald ZeroU DisplayPort Transmitter has embedded audio over the DisplayPort connector.

2.2.3 SUPPORT FOR KEYBOARDS, MICE, AND USB DEVICES
Standard 104/105 keyed keyboards and USB keyboards and mice are fully supported by the Emerald system. Composite mouse and keyboard devices are supported, along with other types of USB devices such as Flash/Thumb Drives, CD and DVD/ROM drives,
printers, pen tablets, touch-panels, and isochronous USB devices such as headsets. Specialized keyboards that support LCD panels, macro keys, card readers, and internal USB hubs typically require additional support.
Support for non-keyboard and mice devices is provided on an Emerald Receiver using USB re-direction. This capability can be enabled or disabled by the administrator. In an Emerald Receiver, the first two devices that are not keyboard or mouse are assigned to the USB re-direction channel automatically and passed to the remote computer when connected via a Transmitter. When connecting to a non-Transmitter target (i.e. virtual desktop), up to eight USB devices can be re-directed. The EMD200DV/ EMD200DP series does not support USB-Redirection and only supports keyboard and mouse devices.
NOTE: A hub can be attached externally to an Emerald Receiver, but a maximum of two devices can be assigned to USB re-direction on connections to Transmitters. Multiple keyboard and mice can additionally be supported—though all use the default drivers on the target PC.

2.2.4 IP ADDRESSING
The Emerald devices are IP-addressable, giving you the flexibility to locate workstations anywhere within your enterprise and at any distance from your desktop users. The Emerald devices use standard network protocols to transfer data between the remote
Workstation/Virtual Desktop and the peripheral devices located at the user’s desk. The Emerald system can operate on a network connection of 100 Mbps or 1 Gbps.
The receiver can be configured using a static or DHCP assigned IP address while the transmitter requires a static IP address only.
It is strongly recommended to use Static IP addresses for the Receivers.

2.2.5 FIRMWARE UPGRADE
Upgrade your firmware at any time using Boxilla or using a USB flash-drive in an Emerald Receiver unit to ensure that your Emerald system is always running the most current version available. The Emerald devices —Receiver and Transmitter—are upgradable.

2.3 APPLICATION EXAMPLES
The Emerald system is built to be flexible so that it can be deployed in many different types of applications such as basic extension, switching applications (sometimes called matrix), cloud-based desktops, control rooms, digital signage, and kiosk applications and other applications in banking, financial services, broadcast, network operations, industrial, government and enterprise computing sectors. Emerald provides the state-of-the art performance by:

• using digital sources for video and audio, hence removing analog noise issues or other potential environmental issues
• using advanced optimized compression to enable visually lossless video over standard low-bandwidth networks rather than a proprietary connection or dedicated gigabit networks of many systems

2.3.1 VIDEO, AUDIO, AND USB EXTENSION
Many applications require Video, Audio, or USB extension (or all three together) such as PC back-racking, board-room fit-out, remote monitoring, and digital signage.
The Emerald system is set up to connect the Transmitter to the Receiver straight out of the box on a point-to-point network.
The Transmitter and Receiver can be attached to standard Ethernet IP networks to increase the distance between units – within a building, between buildings, or across a country. Only standard Ethernet/IP rules and the maximum latency the application can
tolerate need to be considered. If video and/or audio extension only is being used, latency rarely is a consideration as the traffic is typically one-way. When USB-based peripheral devices are also required, a network latency of <50 ms is recommended to avoid user issues with “poor mouse response”, etc. For some applications, such as graphic design network latency ,<20 ms may be required to ensure user satisfaction. Latency normally is only an issue when extending across a WAN, because latency inside modern buildings or on dedicated networks is much less than 1 ms.
NOTE: Emerald supports latency of <100ms although <20ms is recommended and anything above 100ms will have undesired results.
In Figure 2-2, a typical deployment is shown in a basic extender application. In this deployment, only one Transmitter and Receiver are used to allow remote access to a single workstation.

2.3.2 VIDEO, AUDIO, AND USB SWITCHING
Numerous applications require being able to switch between different target PCs or Virtual Desktops. The user wants to be able to change the source of Video, Audio, or USB extension (or all three together).
Connections can be made to a target using Emerald’s intuitive On-Screen- Display (OSD), Boxilla Viewer (if using Boxilla), or Favorites Hotkeys. In Figure 2-3, a larger scale system is shown. This is referred to as a switching or matrix type of deployment. In this deployment, there are several Receivers and Transmitters and a manager, as well as virtual desktops.

CHAPTER 3: CONFIGURATION

3.1 CONFIGURATION OF RECEIVER

An Emerald Receiver connects to a physical PC or a virtual desktop over a TCP/IP network and decrypts and decompresses the streams to provide video, audio, and USB connections to a user. The user is presented with typical PC connections—video out
(typically DVI), USB (typically 4 ports of USB 2.0), line out, and microphone in (see individual Receiver’s data-sheets for specific ports provided).
The Transmitter-Receiver connection uses Black Box’s compound compression algorithm for video called Dynamic Content Optimized Compression (DCOC). This algorithm optimizes compression based on content in the video stream and on available network bandwidth. Standard Microsoft RDP is used for connections to Virtual Desktops. Multiple versions of RDP are supported from RDP 8.1 to legacy versions. This allows Emerald Receivers to connect to Microsoft Hyper-V, VMWare ESX, and Citrix XEN based virtual desktops as well as session host based desktops (previously called Terminal Services).
The Receiver is configured using an On-Screen Display (OSD) built into the Receiver or using the Boxilla Manager. The network settings and unit name among others can be configured for a Receiver. The target connections are defined by their target name or IP address, log-in username/password, and TCP port number to be used. Users can be created and specific connections may be allocated to the different users.
A Receiver user profile is protected by username and password to permit different users to access the same unit securely.
Multiplatform support
Emerald is compatible with the following operating systems:

• Microsoft ® Windows Desktop Operating Systems (e.g. Windows 7, Windows 8, Windows 10. and Windows 11) and Microsoft Server Operating Systems (e.g., 2003, Server 2008, Server 2012, Server 2016, or Server 2020)
• Linux®
• Mac OS®

The default keyboard drivers for these operating systems are supported by the Emerald system.
NOTE: For virtual desktops, typically Pro or Enterprise versions of the Windows operating system are required for VDI to support RemoteFX™. See www.microsoft.com for Terminal Services (RDSH) or VDI (RDVH) requirements.

3.2 CONFIGURATION OF TRANSMITTER
An Emerald Transmitter converts the video, audio, and USB connections of a PC or Workstation to a format that can be connected and controlled over a TCP/IP network. The Transmitter connects to the DVI and USB ports of a PC or workstation.
The Transmitter controls the connection to a remote Receiver and manages the flow of information to it. It converts and compresses video and audio information for transmission over standard TCP/IP networks, along with USB peripheral communications. All data communication uses 128-bit encryption.
The Transmitter uses Black Box’s compound compression algorithm for video called Dynamic Content Optimized Compression (DCOC). This algorithm optimizes compression and latency on a frame-by-frame basis, depending on content in the video stream and on available network bandwidth. This enables an optimal user experience in challenging network environments.
The Transmitter is configured from an Emerald Receiver or Boxilla Manager. The network settings, unit name, and video quality are among the parameters that can be configured on a Transmitter.
Multiplatform support
The Transmitter is connected to the remote workstation via USB and DVI connectors. This enables the Emerald Receiver to interoperate seamlessly with Windows, Linux® , and Macintosh© workstations/servers.

3.3 CONFIGURATION OF BOXILLA MANAGER
In a basic installation, you can configure Emerald via an Emerald receiver’s built-in OSD display. For larger installations, a Boxilla Manager (BXAMGR and BXAMGR-R2) can manage a network of Emerald Receivers and Transmitters. The BXAMGR can manage
25 transmitters/receivers by default. It can manage an unlimited number of Emerald transmitters/receivers when using an upgrade license.
A Boxilla user profile is protected by username and password to permit different users to access the same unit securely. It maintains the central database that is distributed to all Receivers in the “domain” of the Boxilla (i.e. discovered and added to manager) – called the “managed domain”. This distribution ensures that there is no single point of failure in the Emerald system – each Receiver has a copy of the database. This enables each Receiver to continue operation – log users in, make connections as required – even if the Boxilla goes off-line.
Using the intuitive Boxilla web-based interface, one or more administrators can manage potentially thousands of users who are interacting with an almost unlimited number of devices. Boxilla operates as a self-contained compact server unit that can be located anywhere within your network. Boxilla is supplied pre-loaded and is straightforward to deploy, requiring only a network connection and a power input to begin operation.
The current version of Boxilla provides management of Black Box’s Emerald system. For more information on Boxilla, refer to the Boxilla user manual.

CHAPTER 4: MODES OF OPERATION

The Emerald system has various modes of operation such as Auto-Login, Auto- Connect, Private Connection, Shared Connection, and Video Source Optimization modes.

4.1 AUTO LOGIN
In Auto-Login Mode, turning on the Emerald Receiver automatically causes a login as a pre-defined user. The user is presented with the permitted connections that have been predefined.
4.2 AUTO CONNECT
In Auto-Connect Mode, when a user logs-in to the Emerald Receiver, it causes an automatic connection to their pre-allocated workstation or virtual desktop. Auto-Login and Auto-Connect are defined independent of each other, but can be used together to auto login/auto connect devices that are difficult to reach.
4.3 PRIVATE CONNECTION
In Private Connection Mode, when a user makes a connection to a target workstation/virtual desktop, this connection is only accessible by this user. All other users will receive a “busy” message if they attempt to connect to the same workstation/virtual machine. This is the default mode for connections.
4.4 SHARED CONNECTION
In Shared Connection Mode, multiple users can connect to the audio and video of the same target computer over the network. They arbitrate for control of the keyboard and mouse of that computer. Non-keyboard and mice devices are not supported
on shared connections (such as USB 2.0 devices due to the timing/OS limitations). Analog audio can now be shared in a shared mode connection.
These various modes can be mixed on a particular Receiver and connection. For example Auto-Login and Auto-Connect can be combined to enable an Emerald Receiver to automatically connect to a specific target workstation/virtual desktop when power is applied without any user intervention that might be required for Digital Signage or Kiosk type of deployments.
4.5 VIDEO SOURCE OPTIMIZATION
Off: In this mode, the transmitter does not perform any additional video functions to manage the video input bandwidth, this mode assumes you are not using any Analog to Digital converters or Temporal Dithering GPU. If you are using converters or have a GPU that does Temporal Dithering, this setting will not work very well as it will saturate the transmitter and cause severe latency. DVI Optimized: This mode is designed to be used with GPUs that support Temporal Dithering. When the GPU updates every pixel
on every frame to show a more vibrant video output, the transmitter in this mode can now ignore certain pixel updates to reduce the risk of GPU bandwidth saturation that can lead to severe latency.
VGA
A: VGA High Performance: When using an analog to digital video converter, these devices can cause video noise to be injected on the signal. The transmitter will view this as a noisy source or a GPU that is using Temporal Dithering. This option is designed more
for VGA to DVI/HDMI converters and will perform the function at a Low capacity.
B: VGA Optimized: When using an analog to digital video converter, these devices can cause video noise to be injected on the signal. The transmitter will view this as a noisy source or a GPU that is using Temporal Dithering. This option is designed more for VGA to DVI/HDMI converters and will perform the function at a Medium capacity
C: VGA Low Bandwidth: When using an analog to digital video converter, these devices can cause video noise to be injected on the signal. The transmitter will view this as a noisy source or a GPU that is using Temporal Dithering. This option is designed more for
VGA to DVI/HDMI converters and will perform the function at a High capacity, filtering the most pixels this setting is considered to be the most aggressive out of the other 2 modes.

CHAPTER 6: NETWORKED INSTALLATION

6.1 POINT-TO-POINT INSTALLATION
In a point-to-point configuration, no administrator setup of the Emerald Transmitter or the Emerald Receiver is required.
This enables you to install the system quickly, directly out-of-the-box. However, in the point-to-point configuration, you can install only one Emerald Transmitter and Emerald Receiver pair on a subnet, and both must be on the same subnet unless a router is
present in the network to span subnets.
Also if there are other devices with 192.168.1.21 (default Receiver IP address) or 192.168.1.22 (default Transmitter IP address) on the network, then the IP addresses for Receiver and/or Transmitter should be changed to unused IP addresses.

6.2 UNMANAGED OR MANAGED MATRIX INSTALLATION
The following instructions will enable you to install your Emerald Receiver and Emerald Transmitter in a networked configuration. In this installation, multiple Emerald Transmitters and Emerald Receivers are attached via the same Ethernet network. In this case, it is important for each unit to be configured with a unique IP address.
The Emerald Receiver has been preconfigured with factory-default network settings. If you install multiple units on the same network, you will need to assign a unique IP address to each unit or configure the Receiver for DHCP. This can be done via the On-Screen Display (OSD) on the Emerald Receiver and must be carried out before adding multiple devices on the same network. It is strongly recommended that all device IP addresses be configured using a static IP address.TABLE 6-1. EMERALD SYSTEM DEFAULT NETWORK SETTINGS

CHAPTER 7: OPERATION OF EMERALD SYSTEM

Operating a workstation through the Emerald system is no different than working directly connected to a PC desktop.
All peripherals operate as if directly connected, even though the workstation is located at a distance.

7.1 LED IDENTIFICATION
Front panel
There is a Power button on the front panel of an Emerald SE unit. This button is disabled. The Emerald PE unit has a power LED but does not have a power button.
NOTE: The SE or PE unit powers on automatically when plugged in and must be turned off at the power source.
The Emerald ZeroU DVI or DP Transmitter unit has a Power LED. It can be powered either via USB or via an optional power supply.
Rear panel
Two LEDs are built into the RJ-45 connectors on the Emerald SE Receiver, Emerald SE Transmitter, and Emerald ZeroU DVI or DisplayPort Transmitter. The definition of the operation of these LEDs is shown in Table 7-1.
TABLE 7-1. RJ-45 CONNECTOR LEDS ON THE REAR PANEL OF THE EMERALD SE RECEIVER AND TRANSMITTER

7.2 ACCESSING THE SYSTEM
A connection is established using the OSD on an Emerald Receiver or Boxilla Manager. You will be able to interact with the remote workstation as if it were located at your desk.
NOTE: If the remote workstation is powered off, the Emerald system will display a “black” screen for video when a connection is made.

CHAPTER 8: OSD FUNCTIONS

The Emerald Receiver and Boxilla Manager incorporate an On-Screen Display (OSD) that allows you to view information about the configuration of your system and potentially also allows for setting connections and configuration parameters such as the IP address, depending on the type of user. The following sections describe the operation common on a Receiver.

8.1 USER TYPES
The Emerald system supports three classes of users for Matrix products:

1. Administrator – users of this class have full rights to configure the system. They can create/modify/delete new users and connections, change network settings, etc.
2. Power User – users of this class can modify resolution for connections to virtual desktops and change his/her local password.
3. Standard User – users of this class can only select from a list of pre-defined connections to access and view system information. They cannot change any configuration settings.

8.2 LOG ON
A user must log-on to the Emerald Receiver or Boxilla Manager to configure and manage the Emerald system. The log-on screen is shown in Figure 8-1. The username defines the access rights and configuration available to the user. The fields on this screen are:

1. Username: the username to log-on as defined by the Administrator. Username is case-sensitive.
2. Password: password for the user. Password is case-sensitive.
3. Remember Me: When this box is checked, the unit keeps the username between log-ons and power-cycles. When this box is not checked, the username field is always presented as blank when powered-up and after a log-out. This tick-box only affects the username – the password is never preserved.
4. Power Button: This button allows the user to reboot the client.

•  System Preferences: This button has a drop down menu that allows the user to define system preferences for the Emerald Receiver. Figure 8-3 shows how the keyboard type can be selected.

Help: This button opens a pop-up window with our website address (blackbox.com) on that screen.
8.3 DEFAULT USERNAME AND PASSWORD
The Emerald Receiver ships with a default username of admin with a blank password (i.e. no password). This user cannot be deleted, but the password can be changed.
NOTE: If you create a password for the default Admin account and forget it, there is no way to reset / retrieve it unless using a Boxilla manager. We recommend that the administrator creates a second Admin account for critical systems in case the main Admin account is locked out. In the event you still cannot gain access, a factory reset may be required.

8.4 USER VIEWS AND CAPABILITIES
There are three different types of users in the Emerald System. Your user type will determine what exactly you will see on your OSD.
For the purpose of this Manual, we show the screen of an Administrator. This means that some buttons shown here may not be available to other users.
The Emerald comes as an unmanaged system and as a managed system. There are some differences in the OSD for these systems which you may see here..
8.5 CONNECTIONS SCREEN
When a user successfully logs on to the Emerald Receiver or Manager, the Connection screen is displayed. This is shown in Figure 8-4. The connections that a user can make are listed in the connection window. The user logged on is shown in the top right corner of the OSD.If the user is an Administrator type, the three buttons on the left (New, Edit, and Remove) will be displayed. These allow the user to create, edit, or remove connections. For Standard User types, no connections can be created, edited, or removed, so these buttons are not displayed or are greyed out. The user will also not see the “Control,” “Users,” and “Information” tabs. By default, there is one connection called “Default Tx – 192.168.1.22” that defines a connection to an Emerald Transmitter with its factory defaults. A maximum of 32 connections can be defined for an Emerald Receiver by default, and these connections can be shared by users as defined by an administrator (different users can have the same connection). The number of connections can be increased to unlimited in a managed domain via Boxilla upgrade licenses.

8.5.1 CREATING A NEW CONNECTION
To allow an Emerald Receiver or Manager to connect to a target Emerald Transmitter, an administrator must create a connection.
The administrator clicks on the New button on the Connections screen. This causes the New Connections pop-up window to appear as shown in Figure 8-5.

The fields on this screen are:

• Name: this is a unique name for the new connection. The name can be between 1 and 32 characters. The name can be composed of any Alphanumeric characters and special characters except for “ ”/ \ [ ] : ; | = , + * ? < > `’.

• IP Address/Host Name: IP Address of Emerald Transmiter (if Connection Via set to Transmitter) or VM in IP v4 format. Alternatively it can be the Host Name if this can be resolved in the local DNS server. Note: Using Host Name will increase the switching time by the time needed to resolve the Host Name to an IP address; Š Port: defines the port to be used for the RDP connection for connections via VM Direct or Broker. Uses 3389 by default;

• Username: defines username to be used on a VM connection. Only used for connections via VM Direct or Broker. If left “blank” on VM Direct – user will be presented with Windows Login screen on VM;

• Password: defines username to be used on a VM connection. Only used for connections via VM Direct or Broker;

• Domain: defines domain that a Virtual Machine is part of (if part of a windows domain). Not used for connections to  Transmitters.

• Load Balance Info: Defines resources on the broker (VM Pool that the receiver will attempt to connect to after user credentials have been validated. Only used on connection via Broker.

• Connection Type: Used to define whether a connection is Private or Shared (i.e. other connections of type Shared can join in session and share keyboard, mouse, and video). Only available if connection via set to Transmitter.

• Connection Mode: To allow users to connect from a 4K Receiver to connect to Emerald SE, PE, and ZeroU transmitters: The connection on the 2K transmitter must be set to Optimized. Go to Connections and create a new connection (or Edit an existing
  connection). Enter all of the connection details (or confirm they are correct) and a new option can be selected for Compression Mode. For 4K RX to 2K TX: Compression Mode = Optimized.

• Enable Extended Desktop: Remote connections can be extended for dual-head Emerald units by enabling the option Extended Desktop. Enable Extended Desktop setting enables the second video head of a dual head Transmitter. Make sure both the video heads on the Transmitter are connected to the source. Video heads on the receiver are connected to respective monitors.

• Enable View Only mode: View only setting for a connection allows user to monitor what is been transmitted from a source without being able to interact with the source. This feature allows a user or administrator to monitor the actions on the network without accidentally interacting with other users. View only connection is available in both private and shared mode connections with or without analog audio.

• Enable USB Redirection: when set, this enables non-keyboard and non-mice devices (such as tablets and USB headsets) to be redirected for this connection.

• Enable Audio: when set, this enables audio to be supplied to the remote audio connectors.

• Enable NLA: when set, this enables Network Level Authentication requiring that the user be authenticated to the RD Session Host server before the session is created. This is not used for when Connection Via is set to Transmitter.

• Persistent Connection: When turned on, Persistent Connection will constantly try to connect the Receiver with the Transmitters until successful. This is useful when using Emerald for digital signage or an application that does not need a keyboard/mouse     to stay connected to a defined source.

8.5.2 CONNECTION FAVORITES
Connection favorites provide a quick convenient mechanism for users to switch between their pre-defined connections. Favorites are configured by the administrator where a maximum of 10 favorites can be assigned to users using a combination of hotkey and [0-9].
Assigning Connection Favorites
A pre-requiste is that the user exists and has connects assigned.
The following screenshot demonstrates the administrator assigning connections for the user to the available hotkeys. Favorites do not need to be allocated sequentially and hotkeys can be skipped.Listing Connection Favorites:
When a user logs in, they can view their assigned favorites.

8.5.3 CONNECTING
To make a connection, the user highlights the required “connection” in the window and then clicks on the “ Connect” button.
Alternatively, a user can double-click on the connection. This action causes the Emerald Receiver to attempt to connect to the target remote workstation or virtual machine. If the target is available, the connection will be made.
The user can also use the arrow and Enter keys on a keyboard to select a connection.
If another user is already connected to the target defined in the connection, the user will receive a pop-up window indicating the target device is already allocated. If connection errors occur, they will be displayed in an error popup window.
8.5.4 EDIT CONNECTION
To edit a connection and change its parameters, an administrator clicks on the Edit button on the Connections screen. The Edit Connections pop-up window appears.
The administrator changes required fields and clicks Save to confirm or Cancel to discard any changes.
8.5.5 REMOVE CONNECTION
To remove or delete a connection, an administrator highlights a connection in the list and then clicks on the Remove button on the Connections screen (shown in Figure 8-8). This causes the Remove Connection pop-up window to appear where a user confirms the removal or cancels the attempt.
8.5.6 BONDING
NOTE: Bonding requires the Boxilla manager.
This assumes that setup is complete on Boxilla and a user has permission to connect to a Bonded connection. See the setup instructions in the Boxilla user manual.
When the user selects a “bonded connection” from any Receiver that is part of a bonded group, Receiver 1 will connect to Connection 1, and receiver 2 will connect to connection 2, and so on, up to 8 bonded links.
Connections will all be made assuming they are available using the normal rules — e.g., If one connection is in a private connection and therefore cannot be connected to — all connections within the bond will fail. The user will get an error message from the user
station they requested explaining why connection could not be made and will identify the user in private connection. Once the user has a successful connection, if they disconnect using the OSD, all connections will be terminated.
While the user is in a bonded connection and if they wish to switch one of the receivers to another connection without dropping the full bonded setup, they shall use favorites and this receiver will switch to the desired target without calling the OSD and leaving all other connections in the bonded connection up and running. The exception to this is that favorites cannot be used from receivers that launched connections via Boxilla.NOTE: Bonding requires the Boxilla manager.

The exception to this is that favorites cannot be used from receivers that launched connections via Boxilla.

8.6 CONTROL TAB
The Control Tab on the OSD enables an administrator to change the configuration of the Emerald system. The Control Tab is shown in Figure 8-8.

There are five functions that can be accessed on this tab:

1. Preferences – allows users to change preference settings for:
   i. Resolution Settings – allows change of preferred resolution for OSD screens and Virtual connections.
   ii. Hot-Key Settings – allows changing of the active hot-key for keyboard short-cuts.
   iii. Timer Settings – allows setting of pre-emption timer and various inactivity timers
   iv. Connection Label Settings – allows activation/deactivation of connection label and set label preferences

2. Network – allows administrator to change network parameters for the Emerald Receiver or Manager.

3. System – allows upgrading of unit firmware, reset unit to factory defaults, and to save/restore unit configuration to a USB drive.

4. Password – change the administrator or user password.

5. Transmitter – allows changing of Transmitter parameters.

8.6.1 PREFERENCES
Resolution
The Resolution button allows an administrator or power user to set the preferred resolution for the RDP Connection and for the OSD. By default, both the RDP Resolution and the OSD Resolution are set to Auto.
The RDP Connection Resolution allows the resolution to be changed for an RDP connection, (i.e. defines the resolution that the virtual desktop will be accessed with). If the preferred resolution is not supported, the Receiver will use the next highest resolution
supported by both monitor and Receiver.
The OSD Resolution is set to Auto by default, but can be changed to the available OSD resolutions if the user wants to set a specific resolution. This setting has no effect when connecting to an Emerald Transmitter.
Click Apply button to save the change. Hot-Key
The Hot-Key button allows the administrator to change the hot-key configuration. The hot-key is used with the “o” key to terminate the current connection and bring up the OSD. The hot-key with “p” key is used to switch to the previous connection without loading the OSD. Example: PrtScrn, O (default).The default hot-key is Print-Screen (PrntScrn). The alternatives are shown in the table. Click the Apply button to confirm a hot-key change.
TABLE 8-1. HOTKEY SEQUENCES

seconds

The “Enable Functional Key” tick-box is used to disable the use of the function keys after the hot-key. So only the Hot-Key is required to bring up the OSD. The Enable functional Key is set by default. If using Favorities, the Enable Functional Key must be enabled.

Timer Settings
There are 2 timer settings available to users as shown in Figure 8-11. By default, they are turned off. If you wish to turn them on, you have to select the desired timer, set the time you wish, and click apply. The three timer settings are:

1. OSD Inactivity Timer – This sets a limit on how long a user can be logged on to the OSD without any keyboard or mouse activity. Once the user reaches the inactivity timer, he/she will be logged out of the OSD. The timer value can be set to a number from 2 to 60 minutes.
2. Connection Inactivity Timer – This sets a limit on how long a user can be connected to a source (virtual machine, Transmitter etc.) without any keyboard or mouse activity. Once the session reaches the inactivity timer, he/she will be logged out of their connection and return to the OSD. The timer value can be set to a number from 2 to 60 minutes.
   NOTE: Inactivity occurs when the mouse or keyboard is not pressed or moved for a set period of time. The OSD Inactivity Timer and Connection Inactivity Timer can be used together to disconnect a session and log out of the user session.

NOTE: There is no screensaver option built into the receivers. If screen burning is a problem, we strongly recommend turning off the displays after use.
Connection Label Settings
The connection label can be enabled to help the user identify what connection is currently being used. This feature can only be enabled per receiver station by a power user or an administrator user. By default the feature is off, and the user can enable it and set
the label to stay for 5 seconds after a connection or stay on screen permanently.
Note: This feature is available on all Emerald receivers with the exception of the EMD2002SE.

The Connection Label is enabled through the Control Tab. The Control Tab’s Preferences options are shown in Figure 8-12.The user can toggle the label on or off by using their hotkey and pressing “L”. In Figure 8-13, the Connection Label is enabled.The user can select to always display the connect label or to display it for 5 seconds. In Figure 8-14, a 5 second time out is selected.The user can also select where the label will appear on the screen. In Figure 8-15, “Bottom Centre” is selected for the location.Figure 8-16 shows the connection label located in the bottom center of the screen, based upon the location selected in Figure 8-15. 8.6.2 NETWORK
The network screen shown in Figure 8-17 allows an administrator to change the settings for the Emerald Receiver or Manager. The default network setting for the Receiver is a static IP address of 192.168.1.21. It has a Network Mask of 255.255.255.0 and a Gateway 192.168.1.1. If DHCP is selected, the Receiver gets its IP address from the DHCP server. Click the Apply button to confirm any changes to network settings.
NOTE: We strongly recommend using Static IP addresses on the receivers. Also, only IPv4 addressing supported in the current firmware version. 8.6.3 SYSTEM
The System screen shown in Figure 8-18 allows an administrator to upgrade the firmware in the Emerald Receiver, reset it to factory defaults, import/export the configuration to an external USB drive, and perform a system diagnostic. System Upgrade
The Emerald Receiver can be upgraded using a FAT32-formatted USB Flash drive. Simply take the firmware file and place it in the root directory of the flash drive. When you click the Upgrade button, the “valid” upgrade files on the USB drive are displayed. A valid file has the extension .clu – an example is shown in Figure 8-19. NOTE: There can only be one USB key/pendrive inserted in the RX and that key must contain the upgrade files. If the user has two keys inserted , and the second key has the upgrade files, the system will not locate the required files. Once the administrator has selected the file and clicked Ok, the system checks that the selected file has no errors before upgrading the Emerald Receiver. The configuration of the unit is preserved through the upgrade.
NOTE: Always update the Transmitter first before the Receiver.
Restore Factory Defaults
The administrator can click the Restore button to reset the Receiver back to factory defaults.
System Diagnostics
The diagnostics provides information for Black Box to debug customer encountered issues. When this button is clicked the user is asked to save the diagnostics onto a memory stick in the Receiver unit. This file should be sent back to Black Box for analysis.
There is a similar diagnostic that can be run on a transmitter.
Password
The Password button when clicked allows the current user’s password to be changed. This button is only visible to Administrators. Transmitter Button
The Transmitter button on the Control Tab allows administrators to change the configuration of an Emerald Transmitter (this button is only visible to administrators). The following options are available when the Transmitter button has been activated:

1. Transmitter Information
2. Transmitter Firmware Upgrade
3. Transmitter restore factory defaults
4. Transmitter reboot
5. Transmitter Preferences
6. Network Settings
7. Discover Transmitter IP address

Configuring a Transmitter
To configure a Transmitter, the IP address must be defined for the target Transmitter. When there is no active IP address defined, the TX Setting window has all the buttons grayed out except for the Apply and Discover buttons.
The IP address for the transmitter can be entered into the field at the top of window and click Apply button to activate. If a valid IP address is entered, the Transmitter settings window makes all the options available for the administrator shown in Figure 8-24.
Alternatively the Discover button can be used to find the IP address of a transmitter. First click the Discover button and follow the instructions. Basically once in discovery mode, the Receiver (or Boxilla Manager) can capture the IP address from a Transmitter once it has been power-cycled.
NOTE: The default network setting for the Transmitter is a static IP address of 192.168.1.22. It has a Network Mask of 255.255.255.0 and a Gateway 192.168.1.1.

If the IP address of the Receiver and Transmitter are not on the same subnet, a router is required to allow them to communicate.
This is true even when the Receiver “discovers” the Transmitter’s IP address. One way to avoid this is to change the Receiver address to be on the same subnet as the Transmitter, make the required configuration changes to the Transmitter, and then change
the Receiver back to its required IP address.
Transmitter Information
The Information button provides Transmitter related information such as Device Model, Serial Number, MAC address, and current Firmware Version to the administrator.
If the active IP address is not the address of a valid Emerald Transmitter or this address is unreachable, an error message is returned.
Transmitter Upgrade
The administrator can click the Upgrade button to change the firmware on a Transmitter. The upgrade file is selected from the set of files on an attached USB drive. These files will have the extension .clu . The selected file is checked to be a valid Transmitter
upgrade file before starting the upgrade. The OSD provides a series of screens to walk the user through the process.
The upgrade can take a few minutes to complete and the power to the Transmitter and the Receiver must not be disconnected during the upgrade. During the upgrade process, the Transmitter may reboot.
If the active IP address is not the address of a valid Emerald Transmitter or this address is unreachable, an error message is returned.
Transmitter Restore Factory Defaults
The administrator can click the Restore button to reset the Transmitter back to factory defaults. If the active IP address is not the address of a valid Emerald Transmitter or this address is unreachable, an error message is returned.
Transmitter Reboot
The administrator can click the Reboot button to power-cycle the Transmitter. If the active IP address is not the address of a valid Emerald Transmitter or this address is unreachable, an error message is returned.
Transmitter Preferences
The administrator can click the Transmitter Preferences to change Video Quality Setting or HID Configuration. When the Transmitter Preferences button is clicked the window shown in Figure 8-25 pops up. Transmitter Video Quality Settings
The transmitter uses a progressive compression algorithm with 5 stages to reduce the bandwidth and increase the frame rate while sacrificing quality. At stage 5, which uses the best compression, you may achieve a higher frame rate and lower bandwidth, but the
video output may show blocks of pixilation or screen artifacts as those parts of the screen are not being repainted because they didn’t update. At the highest setting of stage 1, which is best quality, you will not see these screen artifacts as much, but you will be using a higher bandwidth with reduced frames potentially based upon your application. Frames are not always reduced; it just depends on the source and network.
Options:

1. Best Quality – lossless compression, pixel-perfect mode of operation. Generally needs dedicated network to ensure no frame loss.
2. Visually Lossless Compression – high quality visual image. Some compression on stream to reduce bandwidth to allow operation on standard corporate networks. Compression does not vary based on available network bandwidth, so may lead to some dropped frames during network congestion periods.
3. Optimized Quality (default) – system tuned to maintain visually lossless compression while increasing compression level during periods of network congestion to reduce frame loss. Balances visual quality with frame loss in periods of congestion (i.e. attempts to reduce/eliminate frame loss).
4. Optimized Bandwidth – system tuned to maintain visually lossless compression but increased levels of compression level during periods of network congestion to reduce frame loss. Optimized towards lower bandwidth during congestion periods compared to level 3.
5. Lowest Bandwidth – high level of compression to minimize average network bandwidth. No dynamic change to compression levels – always seeking to reduce bandwidth.
   If the active IP address is not the address of a valid Emerald Transmitter or this address is unreachable, an error message is returned.

Video Source Optimization
This is a progressive algorithm which helps to reduce unwanted noise coming from a GPU or Video Converters. The transmitter can be configured to handle different applications by changing the way it handles the video signal if it natively has embedded noise
(i.e. from a VGA to DVI converter). You can choose to use “DVI optimized”, “VGA high performance”, “VGA optimized”, or “VGA low bandwidth” settings. You may change these options to get the best performance out of the transmitter. When the option is “off,”
no dithering/noise techniques are enabled. “DVI optimized”, which is the least aggressive technique, uses a digital anti-dithering/ anti-noise technique to reduce the extra noise which will allow the Transmitter to operate at a normal pace and have better network

performance. “High performance” is best used when there is an analog to digital video converter between the GPU and Transmitter. It uses a low level technique. “VGA optimized” is best used when there is an analog to digital video converter between the GPU and Transmitter. It uses a medium level technique. “VGA low bandwidth” is best used when there is an analog to digital video converter between the GPU and Transmitter. It uses a high level technique. This would be considered the most aggressive technique to
handle video dithering/noise.
NOTE: VGA Optimization is only supported on Single Head Transmitters; the Dual Head Transmitters and Emerald4K do not support it.The Dual Head Emerald SE / PE may not be the best option for sources that use Video Dithering technology.
HID Configurations
This setting applies to all transmitters. It changes the USB communication between the Emerald transmitter and the target computer/device. “Default” will pass all available signals including audio, USB-R, USB HID as well as keyboard and mouse connections. “Basic” will pass USB HID only. It provides compatibility with DKM, DCX and older servers that require a keyboard and mouse HID only. Basic HID is also required to access any computer’s BIOS menus. “MAC” supports MacOS users. “Absolute” will be used with Windows® /Linux when RemoteApp or Freedom are being used in the setup. For normal usage, where mouse is directly connected to Receiver, then the “Default” or “Basic” options should be used. “Absolute MAC” will be used with MacOS when used
with Remote App or Freedom. “Absolute Basic” allows you to set the mouse to absolute while disabling the emulated audio device.
This setting will typically be used where you wish to use the remote app and integrate the Emerald system with DKM and other systems that may be disrupted with audio enabled.
OSD option:
EDID Settings
The transmitter can support native EDID options such as “1920×1080”, “1920×1200”, “1680×1050”, “1280×1024”, “1024×768”, or you can choose to use the remote monitor EDID by clicking on the “Generate Clone” button which will copy the desired video resolution to display at the receiver. The new EDID option will be added to the drop-down list, and it must be selected and saved before it is applied. This information is then shared with the computers GPU so it sends the correct resolution and refresh rate. The Clone EDID 2 option applies to all dual-head transmitters and allows the administrator to choose the desired video resolution to display at the receiver’s second output.
NOTE: The computer may need to be restarted in order for the settings to work. If you find that changing the EDID settings makes the remote monitor blank out, you may need to select a different option to make it work. Once the Generate Clone EDID process is finished, it needs to be selected in the drop down list and is not automatically applied until then.

Transmitter Network Settings
The administrator can click the Network Settings button to edit the Transmitter Network Settings.
To change the IP address settings for a Transmitter, the administrator can enter the new IP address, subnet mask, and gateway, and then click on the Apply button.![Black Box EMD200DP-T Emerald Zero U DP KVM-over-IP Transmitter

• Figer 40](https://manuals.plus/wp-content/uploads/2024/02/Black-Box- EMD200DP-T-Emerald-Zero-U-DP-KVM-over-IP-Transmitter-Figer-40.jpg)

If the new IP address for the Emerald Transmitter is on a different subnet than the Receiver, the Receiver or Manager will not be able to communicate with it without going through a router. This is the case even on a point-to- point link between devices.
If the entered IP address is not the address of a valid Emerald Transmitter or this address is unreachable, an error message is returned.
Discover Transmitter IP Address This requires the Transmitter to be connected to the Receiver on a point-to-point link or be the only Transmitter on the attached network. in this case, the administrator can click on the Discover button and follow the wizard to discover the IP address of the attached Transmitter. This is required in the case when an administrator does not know the IP address of the Transmitter.
Transmitter Diagnostics
The Transmitter provides diagnostics information for Black Box to debug customer encountered issues. When this button is clicked the user is asked to save the diagnostics onto a memory stick in the Receiver unit. Send this file back to Black Box for analysis.

8.7 MANAGING USERS
Users are defined in the Emerald system to provide rights to manage the system, rights to connect to different target devices and set parameters for connections. There are three types of users that can be created in an Emerald system.

1. Administrator – users of the class have full rights to configure the system. They can create/modify/delete new users and connections, change network settings, etc.
2. Power User – users of this class can modify resolutions for connections to virtual desktops and change his/her local password.
3. Standard Users – users of this class can only select from a list of pre-defined connections to access and view system information. They cannot change any configuration settings.

The Emerald Receiver has one default user – admin, which is a member of the administrator group. This user is defined by default and cannot be deleted. An Emerald Receiver or Manager can have a maximum of 32 users defined, unless in a manager domain with an “upgrade” license installed. With the upgrade license installed, unlimited users can be defined.
To manage users, an administrator selects the Users tab (this Tab is only visible to Administrator class users). 8.7.1 ADD A USER
To add a user, click the add button. This causes the New-User window to be displayed.
8.7.2 AUTO LOG ON
When the Log-on button is selected and a user is chosen, this user will be automatically logged on after power is applied to unit or after a reboot.When adding a new user, the following fields are used to define the user:

• User Name: This is a unique name that uses 1–32 characters. The username can be any valid username for a Microsoft O/S.
  This means the username MAY NOT contain “ ”/ \ [ ] : ; | = , + * ? < > `’.

• Password: This field can be a minimum of 0 characters (i.e. blank) and a maximum of 32 characters. The password can be any valid password for a Microsoft O/S. The user password MAY contain the following special characters , ~ : ! @ # $ % ^ & ‘ { } which means the password cannot contain “ ”/ \ [ ] : ; | = , + * ? < > `’

• Confirm Password: This field must match the Password field. If there is a mismatch, a message is presented to the user in a pop-up screen.

• Privilege: This field, which is a drop-down list, defines the type of user the new user will be—Administrator or User.

• Selected Connections: The new user must be allocated Connections that he/she can access. These are selected from the Available Connections window by the user selecting a set of connections (click on the connection in the Available Connection window and then click the “Add” button). This causes the selected connections to be “added” to a user’s selected connection window.

• Connect to at login: This tick box defines whether the Emerald Receiver or Manager attempts to connect immediately to the selected connection after a logon by the user. This automatic connection only occurs after a logon. If a user exits the connection, the connection tab is displayed to the user for selection of a connection. This Connect to at Login is only saved when the Save button is clicked. If not clicked and another tab is selected, the changes are ignored. If not ticked, no automatic connection is made on log-in.

Once the new user fields have been filled out, the Save button must be clicked to create the new user. Clicking the Save button causes the validation of the new username checking that it is unique and that the two password entries match. If this validation

fails, a pop-up window displays the reason for the failure – and the new user is not created. After dismissing the pop-up window, the user can fix the error and click Save again.
The Cancel button should be clicked if the new user is not to be created.
8.7.3 EDIT A USER
To edit a user, click on the Edit button. This causes the Edit-User window (shown in Figure 8-30) to be displayed.This window allows the user privilege type, the permitted connections available, the password, and the auto-connect option to be changed.
The default “admin” account gets access to all connections; this list cannot be modified. Other administrator-type users can have their connection list modified.
Once the changes have been made for a user, they only become active once the Save button has been clicked. The changes can be abandoned by clicking the Cancel button.

8.7.4 REMOVE A USER
To remove a user, highlight the user’s name and press “Remove.”When the Remove button is clicked, a pop-up window is displayed to prompt confirmation that this user is to be deleted. Click the Yes button to remove the user. Clicking the No button causes this action to be aborted and the user is not removed.
NOTE: There must always be a user of the name admin in the Emerald system so the system can always be administrated. When attempting to remove the user, the system checks if the username is admin before it will allow the user to be removed.

8.8 LACP
NOTE: LACP requires the Boxilla manager.
To find out more information about the status of the Emerald network interface(s), the Boxilla administrator can navigate to Devices>>Settings, and click on the “LACP info” panel. This will give a summary of the status of each Emerald NIC interface. Some
of the information that can be found on this page is:
Active: Is the Ethernet port currently active

• Status: If the link is up or down
• Link Speed: The negotiated speed of the NIC
• Media: The type of network cable being used
• LACP: If the data is using LACP traffic

The Emerald LACP features do not support aggregation of the network ports to support two active ports. Only one network port is active at the same time, and both network ports will use the same IP settings. This protocol enables a network device to automatically bundle links by sending LACP packets to a directly-connected device that also uses LACP.

APPENDIX B. CONFIGURING WINDOWS 7 VIRTUAL MACHINES

A few properties must be configured on a target Windows Virtual Machine for Emerald to connect with it.
On the Windows Virtual Machine click on the Start button and launch a command window. Then launch group policy editor – gpedit.msc.
Start >> Run >> “cmd” >> “gpedit.msc”
Once the Local group Policy editor is open follow this path:
Computer Configuration >> Administrative Templates >> Windows Components >> Remote Desktop Services >> Remote Desktop Session Host >> Remote Session Environment
Ensure the following three policies are set as follows:

1. Optimize visual experience when using RemoteFX.
   • For this policy set both the “Screen Capture Rate” and “Screen Image Quality” to Highest.

2. Configure RemoteFX.

3. • Set this policy to enabled

4. Limit maximum color depth.
   • Set this policy to “Client Compatible.”

Once the above policies have been applied, reboot the Virtual Machine. It is now enabled for Emerald connections.
There are different settings to optimize the performance of Emerald with different Windows operating systems. These are defined in the application note – Emerald Group Policies for Optimal Performance for Windows Targets.
It is not possible to connect to a transmitter from a computer/laptop running RDP. A receiver is always required.

APPENDIX C. EMERALD NETWORK PROTOCOLS OVERVIEW

Emerald uses standard IP protocols for communication between Receivers and Transmitters. Port 3389 is used for unicast communications.
For management purposes some other ports are used. The Black Box Discovery protocol used UDP Multicast Group 224.0.1.249 (port 39150). This is sent by the Boxilla Manager to discover Emerald devices in the network. The router must allow UDP Multicast forwarding to allow devices on subnet different to where Manager is located to be discovered.
Emerald devices respond to the discovery multicast by sending a UDP unicast back to Manager IP address on the same port (Por t 39150).
Once an Emerald device is part of the managed domain, the Manager periodically “audits” the device to determine information such as if the device on-line, who is logged into devices, device statistics, etc. These audit requests and responses are unicast UDP to specific IP addresses (responses are sent back to Manager’s IP address) on port 39150.
On power-up, a Transmitter sends out a “here I am” multicast message on multicast group 225.0.0.37 on port 12345.
As part of management configuration, the Manager may communicate to a specific device on port 22 (TCP unicast communications).
Emerald can operate across multiple VLANs or subnets. Basic IP networking rules need to be followed; there should be a router in the network to enable the various devices on different subnets to communicate with each other.
To allow Black Box’s Emerald discovery protocol to operate, Multicast routing should be enabled. Black Box’s Emerald “discovery” protocol is not required for Emerald systems to operate but it is recommended to enable an Emerald Manager to search for devices across the network. If the Emerald SE discovery protocol is not enabled, i.e. router does not have multicast routing enabled, the administrator will have to manually add in all devices not on its subnet, i.e. add in each device individually by its IP address.

APPENDIX D. TROUBLESHOOTING

This page covers some basic notes & troubleshooting when using the Emerald.
Operating Modes: Connecting to an Emerald transmitter from an RDP client that is from a laptop / computer is not possible; you must use an Emerald receiver for this. An Emerald receiver can connect to an Emerald transmitter and RDP server.

TABLE D-1. OPERATING MODES CONFIGURATIONS

Sluggish Mouse: When using the Emerald, you may find that the mouse is not being very responsive, or has a noticeable delay.
This can typically occur if the video card is using Dithering technology. You can contact Black Box to get a small utility to disable video card dithering on AMD graphics cards or use Video Optimization, which is set on the Transmitter -> Preferences page for Single Head Transmitters only.
