Manual for the Protec Bytelan KVM/4
The switches are used when cascading more than a single BYTELAN KVM. It specifies the scan rate, and which KVM unit the keyboard and mouse are connected to. For a single KVM, use the default settings.
SW1 SW2 Scan Rate
----------------------
ON ON 2 seconds
OFF ON 10 seconds
ON OFF 20 seconds
OFF OFF 40 seconds
SW3 NOT USED
SW4 ON For KVM unit with KB/mouse
OFF For other KVM units w/o KB/mouse,
If your power supply isn't adequate, it may cause your KB/mouse problem. It should be 9VDC with at least 500ma.
Hope this helps.
Please describe your problem in more detail please. Then we can figure out or narrow the problem down. It sounds like some power mosfets or output transistors got shorted. I need to know what happened first, why it stopped working.
