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 performance or compatibility of 3
rd
-party webcams.
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.
