The Amer Networks KCB-1410 cable allows you to connect up to two PS/2 keyboards and/or mice to a single USB port. With this device, you no longer need to purchase new peripherals when upgrading to a new computer or operating system that doesn't support PS/2. The plug and play design requires no drivers to be installed, and the product is compatible across multiple operating systems. In addition to connecting PS/2 peripherals to USB computers, the cable allows other PS/2 KVMs to be connected to USB computers, allowing a single KVM to control both PS/2 and USB computers simultaneously.
