ATEN CL-1208 User Manual page 13

Note: 1. The CL-1208 / CL-1216 does not support serial mice. You cannot
use Serial-to-PS/2 adapters with the cables. Attempts to do so will
not work.
2. If your computer uses an AT style keyboard socket you will need to
purchase a PS/2-to-AT keyboard adapter (Part No. 2A-106, or any
standard keyboard adapter), in order to plug the cable into the
computer's keyboard port.
