All Adder KVM switches for PC platform support both PS/2 connections and also the older style AT keyboard/RS232 mouse. They have developed a "combo" cable which combines the VGA video cable with the PS/2 cable for keyboard and mouse.
This cable style is very convenient because only a single cable is required for each PC connected and also the connectors are color coded to the latest specifications to ensure correct identification.
Users with the older style PC AT keyboard/RS232 mouse connections can order the cable complete with the adaptors required.
