I use a four port USB to serial adapter that connects to four Elecraft devices. It's almost as cheap and a bit simpler than a switch and associated cables. Gearmo makes it and I bought mine from Amazon. You might want a KXSER cables or the equivalent for the KAT500. Or use the KXUSB that comes with it.
