Please let us know if there is anything else we can help you with!

Question: Is it possible that the X-USBPRO-US can go through a switch considering that it is only for a workstation?
Answer: Thank you for your inquiry,

You can indeed use the X-USBPRO-US KVM Extender to extend the distance between your source computers and the KVM Switch, or to extend the KVMs local user station -where you control the switch- further away.

If you are looking for a IP / LAN based extension solution through a network switch instead, you may be interested in the AdderLink INFINITY solution instead. You could get a ALIF1002AT-US Transmitter with a ALIF1002R Receiver and simply connect them together through a network switch. With the additional Infinity Manager you can also expand this point-to-point extension application into a multi-point switch or splitter / broadcast solution.

Please let us know if you have any questions or there is anything else we can ever help you with!
