   In this example, the source connected to the DisplayPort input (DP IN), will be output to the HDMI OUT port.
   The DP IN port is the static source and the HDMI OUT port is the static output. This particular configuration will allow the USB-C and both HDMI IN ports to be routed to the HDBaseT OUT port, as needed.

6. Click the Fallback Input drop-down list and select the desired fallback port, if desired. The default setting is Previous.

7. Matrix with static route configuration is complete.

Auto-Switching
The AT-OME-MS42 provides auto-switching capability, which is enabled by default. This feature will automatically switch the input to the most recently-connected source. If a source is disconnected, then the input will automatically be switched to the previously-connected source. If no sources are found, the AT-OME-MS42 will initiate a fiveminute countdown timer. If no activity takes place within this time interval, the unit will automatically power-off.
IMPORTANT: The auto-switching feature is only available when the Switching Mode is set to Mirrored or Matrix mode with static route. Refer to Switching Modes (page 16) for more information.
Enabling / Disabling Auto Switching
By default, auto-switching is enabled on the AT-OME-MS42, allowing the unit to automatically switch between inputs when sources are connected or disconnected. Auto-switching is enabled when set to Matrix mode with static route and cannot be disabled.

1. Login to the web server. Refer to Introduction to the Web Server (page 50).

   NOTE: The AT-OME-MS42 retains the currently selected input, even after the unit is powered-off then powered-on. The system should re-evaluate the auto switching logic after power on and select an input.

5. Auto switching configuration is complete.

Setting the Fallback Input
The default fallback port is set to Previous. This means if multiple sources are connected, then disconnected, the AT-OME-MS42 will automatically return to last-connected port. If desired, the fallback port can be set to another input.
IMPORTANT: The fallback feature is only available when the Switching Mode is set to either Mirrored or Matrix Mode w/ static route. Refer to Switching Modes (page 16) for more information.

1. Login to the web server. Refer to Introduction to the Web Server (page 50).

2. Click A/V Settings in the menu bar.

3. Verify that the Switching Mode is set to either Mirrored or Matrix Mode w/ static route.

4. Click the Fallback Input drop-down list to select the desired fallback input. The default fallback input is Previous.
   If Previous is selected, then the switcher will return to the last-connected input. If no input is found, then it will attempt to switch to any available input.

5. Fallback port configuration is complete.

Scaler Pass-Through
Click this toggle switch to enable or disable the scaler pass-through feature. When set to the ON position,  4K content will be down-scaled to 1080p. When set to the OFF position, the output resolution / timing will be thesame as the input source. The default setting is ON.
IMPORTANT: The scaler will only downscale the image resolution and does not support frame rate scaling/conversion such as 60 Hz to 30 Hz. The frame rate of the source must be supported by the display device

Notes on Scaling
The following section provides important information about how the AT-OME-MS42 processes 4K (UHD) video signals.

• The HDMI OUTPUT port supports up to 4K @ 60 Hz, 12-bit, with HDR.
• If the source is 4K, and the HDMI OUTPUT port is connected to a 1080p (not 4K-capable) display, then the output will be down-scaled as follows:
  Input| Output
  ---|---
  4K @ 24 Hz| 1080p @ 24 Hz
  4K @ 30 Hz| 1080p @ 30 Hz
  4K @ 60 Hz, 4:2:0| 1080p @ 60 Hz, YUV/RGB 4:4:4
• HDR / Dolby Vision / HLG formats cannot be down-scaled to 1080p.
• The internal scaler will be bypassed if the connected display supports the resolution and timing information from the source device.
• The HDBaseT OUTPUT port supports up to 4K @ 60 Hz. However, HDR is only supported at lower resolutions.
• The HDBaseT OUTPUT port will down-sample to 4:2:0, if the source is 4K @ 60 Hz, 4:4:4, 8-bit. However, the HDMI OUTPUT will remain at 4K @ 60 Hz, 4:4:4, 8-bit, if the output is connected to a 4K-capable display.

Audio Management
The AT-OME-MS42 provides control over audio muting on HDMI OUT, HDBaseT OUT, and ANALOG OUT outputs.

2. Click A/V Settings in the menu bar.
3. Locate the Audio section.
4. Click the Analog Audio Output De-embedded from drop-down list to select the desired output.

HDCP Content
Normally, if a source is transmitting HDCP content to a display that is not HDCP-compatible, then the resulting image on the display can be “snow”, image flickering, or no picture. For example, in the illustration below, a laptop source is connected to the AT-OME-MS42. A non-compliant display is connected to a receiver, which is connected to the AT-OME-RX21 using HDBaseT.
IMPORTANT: Not all source devices are capable of transmitting non-HDCP content. For example, Sony PlayStation® gaming consoles and Mac® computers always transmit HDCP-encrypted content.

By default, the laptop may transmit HDCP content. However, when connected to a display that does not support HDCP, the laptop must be instructed to send non- HDCP content, in order for the content to be displayed.

1. Login to the web server. Refer to Introduction to the Web Server (page 50).
2. Click A/V Settings in the menu bar.
3. Locate the HDCP section.
4. Click the toggle switch next to the desired input. In this example, clicking the USBC toggle switch and setting it to the OFF position will instruct the source device to send non-HDCP content, if possible. If the display is unable to receive HDCP content, then a green splash screen will appear on the connected display, with the following message:

HDCP INCOMPATIBILITY

EDID Management
Before a source can send picture and sound to a display device, the source reads the EDID (Extended Display Identification Data) stored in the display. The EDID contains information about what type of video and audio formats are supported by the display. The AT-OME-MS42 can use either the downstream EDID (from the display/sink) or use a built-in EDID preset. EDID data can also be stored in any of three EDID presets. This section will cover each of the following topics:

• Using the Downstream EDID
• EDID Presets
• Storing EDID Data

Using the Downstream EDID
By default, the AT-OME-MS42 will read the EDID from the display device. The term “downstream” is used to describe any device that receives a signal from another device. For example, if a Blu-ray player is connected to a display, the display is said to be “downstream” of the Blu-ray player.

1. Login to the web server. Refer to Introduction to the Web Server (page 50).
2. Click EDID in the menu bar.
3. Locate the EDID Settings section.
4. Click the drop-down list, next to the output that is connected to the display device, and select Connected Display. For example, if the DP IN port is connected to a display, click the DisplayPort drop-down list.

802.1X Security
802.1X is a server-based port authentication protocol which restricts unauthorized (rogue) clients from connecting to a Local Area Network through a public port. In its simplest form, 802.1X usually involves three parties: supplicant (client device), authenticator (Ethernet switch), and an authentication server. Before the device is permitted on the network, port communication is restricted to Extensible Authentication Protocol over LAN (EAPOL) traffic. If the device passes the authentication process, then the authentication server notifies the switch, allowing the client to access the LAN. A full explanation of the 802.1X protocol is beyond the scope of this manual. However, the illustration below shows the basic architecture.

1. Login to the web server. Refer to Introduction to the Web Server (page 50).

   • Anonymous identity
   Enter the identity of the authentication server in this field. EAP uses this field to identify the correct authentication server which will process the credentials. For example, if foo@authserv.com is entered, then this identifies AUTHSERV as the RADIUS (authentication) server.
   • CA certificate
   Click the Browse… button to select the certification authority (CA) certificate. To remove a certificate, click the Remove button.
   • Username
   Enter the username in this field

Solution Setup and Configuration Guide
The following sections provide step-by-step instructions for the following topics:

• Display Control
• Control Mode

Display Control
The AT-OME-MS42 provides various methods for display control: CEC, IP, and RS-232. No external control system is required. Each of these methods will be covered in this section.
IMPORTANT: The AT-OME-MS42 Switching Mode must be set to either Mirrored or Matrix Mode w/ static route. Display control is not supported under Matrix Mode. Refer to Switching Modes (page 16) for more information.
CEC Control
Consumer Electronics Control (CEC) is the simplest method when working with a display. The DISPLAY button, on the front panel of the AT-OME-MS42, can be programmed to toggle power on the display, allowing for convenient remote control of the display device. Note that the display must have CEC enabled to receive CEC messages.
Consumer Electronics Control (CEC): Atlona has confirmed proper CEC functionality with several current models of Samsung, Panasonic, and Sony displays. However, it is not guaranteed that CEC will work with all displays. Many manufacturers do not support the CEC “off” command, and older displays use proprietary commands. Atlona only supports displays that use the CEC command structure defined in HDMI 1.2a. It is recommended that dealers request an evaluation product from Atlona, before designing a system using the CEC protocol. If this is not possible, then other control methods will need to be considered, in order to control displays using Atlona products.

1. Connect an HDMI cable from the HDMI OUT port on the AT-OME-MS42 to an HDMI input on the display device.
2. Enable CEC on the display device. Refer to the documentation for the display device. It should be noted that different manufacturers will identify CEC with their own brand name. Refer to the table below.
   Manufacturer| CEC Designation
   ---|---
   Hitachi| HDMI-CEC
   LG| SIMPLINK
   Philips| EasyLink
   Samsung| AnyNet+
   Sony| BRAVIA Sync
   Toshiba| CE Link / REGZA Link
   Visio| HDMI-CEC
