Frequently Asked Questions - SW-540-TX WyreStorm

How do I set up wireless casting?

Connect to the switcher's built-in access point (SSID matches Device Name). Use default AP mode (Router) to bridge to LAN. Enable AirPlay or Miracast, optionally set an access code for security.

Can I use the switcher without an existing network?

Yes, in Router mode the switcher acts as a standalone wireless AP, providing a local network for casting without internet access.

How do I adjust the EDID for a specific input?

Go to the EDID Settings page in the web UI. Select the input port (e.g., HDMI1) and choose a pre-loaded EDID file (e.g., 4K@30Hz Audio 2CH PCM) or upload a custom binary file. Click Apply and restart the switcher if needed.

What does multiview mode do?

Multiview allows up to 4 sources (wired or wireless) to be displayed simultaneously on Output1. The layout auto-builds based on the number of active inputs. You can customize layouts via API commands.

How do I secure the web interface?

The web interface uses HTTPS by default. You can disable it if needed. For API security, enable TLS and change the default password. Keep default credentials for compatible drivers.

What is the maximum USB speed over HDBaseT?

Due to HDBaseT limitations, USB 2.0 bandwidth is restricted to 190 Mbps instead of full 480 Mbps. This may affect isochronous devices like webcams. WyreStorm recommends their own cameras for guaranteed performance.

How do I force a specific output resolution?

In the Output Settings page, select the output and choose a video timing (e.g., 1080P@60). This forces the scaler to output that resolution. Note: only affects HDMI, not HDBaseT.

Can the switcher automatically turn off the display?

Yes, via Control Strategy. Set an auto-standby timer (0-60 minutes). When no input sync is detected, the switcher sends a power-off command via CEC or RS232 (or both).

How do I replace the splash screen?

Upload a custom image via the Splash Screen page in the web UI. The default screen shows connection instructions; replace it with a company logo or background image.

What if I have USB switching issues?

By default, USB host auto-switches based on the most recent computer connection. You can disable Auto in the web UI and manually select which host port (USB-B or USB-C) is active.

USB Behavior & Performance

The SW-540-TX-W features three USB host ports. Two ports are USB Type B connectors and the third utilizes the USB-C port. By default, the switcher is configured to auto-switch based on the most recent USB connection made to a computer.

With the exception of the USB-C input, the two USB Type B host ports are not tied to any video input. Meaning that USB auto-switching is independent of video auto-switching.

USB behavior can be manipulated via the web interface of the switcher. If you do not want the USB host to auto-switch, 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 performance or compatibility of 3^rd -party webcams.

Note: When the switcher is in a multiview layout, the most recent active USB host will remain. If a new USB host connection is made while in a multiview layout, the new host connection will become active.

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.

Network Security

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 multiview 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 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.

Input Switching

Primary	Secondary	Video Source	Timing	Format	Addition
		TYPE-C	NoSignal
		VGA	NoSignal
		HDMI1	1920x1080P@60	YUV444
		HDMI2	1920x1080P@60	YUV444
Show Guide Screen		Full Screen Mode	Matrix Mode		Refresh

Full Screen: Multiview processing is not supported in this mode. Both the Primary and Secondary outputs will mirror the same content.

Input Switching

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.

Input Switching

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 screen casting. 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 screen casting 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/screen cast 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 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.

EDID Settings

TYPE-C	4K@30Hz, Audio 2CH PCM.bin
VGA	1080P@60Hz, No Audio.bin
HDMI1	4K@30Hz, Audio 2CH PCM.bin
HDMI2	4K@30Hz, Audio 2CH PCM.bin

Note: Restart to take effect.

Display Control

The SW-540-TX-W is capable of sending both CEC and RS232 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.

For RS232, enter in the connection parameters for the peripheral device along with the serial strings for power on and off.

These display commands can be triggered in two ways, either via hot plug detect when you connect a PC for the first time or manually via an API command.

Note: RS232 power triggers do not transmit over HDBaseT and only function via the RS232 passthrough port on the switcher.

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.
