For CAS421 which supports mouse translation, connect only PS/2 mouse to
the console. Also do not connect both PC's serial and PS/2 mouse
ports even though your PC may support both.
-
For CAS221 which DOES NOT support mouse translation, only PS/2 mouse connected
to console port will control the PCs' PS/2 mouse port and AT mouse connected
to console port will control the PCs' AT mouse port. You must connect
both PS/2 and AT mouse to console ports if you plan to control one PC's
PS/2 mouse port and the other PC's AT mouse port. Do not connect
both PC's mouse ports even though your PC may support both.

-
Do not move the mouse the mouse or typing keyboard before the CPU Switch
complete the channel switching. If the CPU Switch detects mouse or
keyboard signals input from current channel before the switching is complete,
it will delay the channel switching until there's no more signal
input. In such case, you will feel slight delay in the response of
mouse pointer or keyboard. Stop moving the mouse or typing the keyboard,
and the CPU Switch will complete the switching immediately.
