USB Behavior & Performance
The SW-540-TX-W features 3 x USB host ports. Two ports are USB-B 2.0
connections and the third utilizes the USB-C port. By default, the switcher is
configured to auto-switch the active USB host based on the selected video
input port.
USB-B Host 1 is tied to the VGA and HDMI 1 inputs and USB-B Host 2 is tied to
HDMI 2.
For example, if the active video input on the switch is HDMI 1 the active USB
host port will be USB-B 1. If the active video input is the USB-C connection,
then the USB-C connection becomes the active host port.
This auto-switch behavior can be manipulated via the web interface of the
switcher. If you do not want the USB host to follow an active video input, you
can uncheck the Auto check box and manually choose which host port will always
be active.
The 3 x USB device ports integrated into the switcher support full USB 2.0
data speeds. The SW-540-TX-W is equipped with HDBaseT spec 2.0 and can
transmit USB over the Category output to a compatible receiver (RX-500
recommended). In this scenario, due to limitations with HDBaseT, USB 2.0
bandwidth is restricted to 190Mbps vs the full 480Mbps. Keep this limitation
in mind when connecting isochronous devices such as webcams over HDBaseT.
WyreStorm has tested our own FOCUS webcams and CAM-200-PTZ to work with the
SW-540-TX-W over HDBaseT. WyreStorm cannot guarantee the performance or
compatibility of 3rd -party webcams.
Note: When the switcher is in a multiview layout, USB auto-switching is
disabled and a manual assignment must be made via the web UI or API.
Security
Security protocols are implemented on the SW-540-TX-W including HTTPS for
secure access to the switcher’s web interface and TLS for accessing the API.
HTTPS is enabled by default but can be disabled if required. TLS is disabled
by default and the switcher uses a standard Telnet connection to access the
API. If a secure connection to the API is required, TLS can be enabled. The
TLS connection allows you to change the default password to a custom value.
Keep in mind that WyreStorm drivers will use default credentials. It is
recommended to keep the default credentials unless you are writing a custom
driver for the switcher.
Connection information and API commands can be found in the SW-540-TX-W’s API
document available at wyrestorm.com.
Multiview
The SW-540-TX-W is capable of processing up to four inputs on a single display in a multiview layout. By default, the switcher automatically builds the multi-view layout based on the number of simultaneous sources that are connected. For example, if two laptops are connected via HDMI 1 and HDMI 2 the switcher will automatically build a split-screen layout. If four devices are connected the screen will be split into quadrants. Examples are shown below.
Multiview sources can be any combination of wired and wireless devices
(Airplay & Miracast). For example, an iPad casting via AirPlay and a hardwired
connection via HDMI can be in a split screen layout. Any combination is
possible but limited to four simultaneous streams.
Multiview layouts can be customized via API commands if a specific layout is
required. Refer to the API document for details.
Input Switching & Modes
The SW-540-TX-W features three unique switching modes.
Standard: This is the default mode of the switcher. It supports full-
screen and multiview processing. Multiview layouts are automatically built by
the switch when it detects a second, third or fourth input. When the switch is
in the multiview mode you will be able to select or de-select multiple inputs
for the Primary output (output 1). The Primary and Secondary outputs are
mirrored in this mode.
Full Screen : Multiview processing is not supported in this mode. Both the Primary and Secondary outputs will mirror the same content.
Matrix: In this mode, the Secondary output (output 2) can be matrix switched independently from output 1. However, when in matrix mode output 2 does not support multiview processing. Only a single full-screen input can be selected and displayed on output 2. The Primary output can still process multiview.
Wireless Access Point & Casting
This switcher has a built-in wireless access point that can be used to cast
content via AirPlay or Miracast. There are three modes for the AP.
Router Mode : This is the default mode. When connecting to the AP in this
mode, the switcher acts as a bridge to an existing network via its LAN
connection. This is useful if there is no existing Wi-Fi network available and
you wish to use the switcher as the primary wireless AP.
Router Disabled : This mode doesn’t allow the switcher to bridge the
wireless connection to its LAN port. This mode is useful if you wish to
isolate the wireless casting from an enterprise/existing network. When clients
connect to the switcher’s AP in this mode, they will only be able to
wirelessly cast content. They will not have internet access.
AP Disabled: This mode completely disables the built-in AP. This mode should be used when you plan to use an existing network’s access point(s). This requires a LAN connection to the switcher in order for it to be found and discoverable on the existing network.
There are a number of additional settings related to the AP and screencasting. The AP password can be set to a custom value. This must be an alphanumeric value. It cannot contain special characters or spaces.
Casting can be discretely enabled or disabled separately to the access point.
If you wish to leave the access point enabled but disable Airplay and Miracast
abilities, disable the BYOD functionality.
Also related to screencasting is an access code. By default, no access code is
set, however, you can enable this feature as an extra layer of security to
prevent accidental or malicious casting. The access code can be either a
static 4-digit number or uniquely generated each time a new casting session is
attempted by checking the Auto box.
You can change the AP SSID/screencast name by changing the Device Name field
and clicking apply. The AP also allows for adjusting the wireless channel it
broadcasts on. This is adjustable for both the 2.4 and 5Ghz bands. WyreStorm
recommends leaving this set on the default values. Only change a wireless
channel if severe interference is occurring or connection problems arise.
Before changing the wireless channel, it is best practice to perform a radio
frequency search to show you the surrounding area’s Wi-Fi. This can show you
what channels are already occupied so you can appropriately choose the best
option available.
inSSIDer is a great free software that can analyze Wi-Fi signals and usage.
Output Settings
Each output features a scaler that can be used to force a specific video
timing to a display. By default, the switcher is set to auto-negotiate the
output timing based on a display’s EDID. However, if you experience
compatibility problems you can choose to force a resolution and refresh rate.
Also, by forcing an output timing you may experience slightly faster switching
times.
Note: Forcing an output timing does not affect the HDBT output, only the
HDMI ports.
If you are using the 3.5mm stereo audio output and experience lip-sync
problems, you can adjust the latency on the Output Settings webpage as well.
Simply enter in a value between 0-200ms and click apply.
Adjusting EDID
Each input allows for the manual assignment of an EDID. If you experience compatibility problems with a device, you can adjust the EDID for the input port respectively. You can also upload a custom EDID binary file if the pre- loaded files do not meet a timing requirement.
Display Control
The SW-540-TX-W is capable of sending both CEC and RS232 (RS232 for HDBT only)
signals to a connected display for power on/off.
CEC will use the default one-touch play and standby commands. These values
will work with most major display manufacturers. If you experience issues with
one or both of these default commands not working, you can enter a custom HEX
value for both the Wakeup and Standby commands.
To send an RS232 string to a display over HDBT simply enter the connection
parameters along with the wakeup and standby commands in the RS232 section.
These display commands can be triggered in two ways, either via hot plug
detection when you connect a PC for the first time or manually via an API
command.
The switcher is also capable of automatically sending a power-off command
after X minutes when there is no input sync detected. In the Control Strategy
drop-down enter in a value between 0-60 to set how long the switcher will wait
before sending the power off command. Enter in a value of 0 to disable auto
standby.
You can also choose what type of command is sent (CEC, RS232, or Both) during
auto-sync detection.
Splash Screen
When no video signal is being transmitted, the SW-540-TX-W will display a splash screen. This screen shows quick connection steps, so users understand how to cast to the display. This image can be replaced with any image you require. This is useful for inserting company logos or custom background images based on the installation environment.
