Raloy 6' 2-in-1 USB KVM/Console Cable
The Raloy RCB-6 is a 6ft VGA/USB KVM/rack console cable with VGA + USB server side connections and a DB15 (for VGA and USB keyboard & mouse) KVM/console side connection. This Raloy cable is specifically designed for use with Raloy rack consoles and KVMs using VGA and USB connectivity.
Answer: Thank you for your inquiry. Yes, the cables can be mixed. The USB only part number is the RCB-6.
However, The RCE-6 is a combo cable and should work for either PS/2 or USB. When used with a USB style computer, only the one USB connection needs to be made to pass both keyboard and mouse data.
