Terry,
Yes, I use a Belken as well. I cannot find a voltage/protocol for
PS/2 to Serial convertion. I have been looking, but cannot find one.
The PS/2 mouse uses 5v and the Serial expects +-12v signals. Although
it is a Microsoft dual mouse (aka: PS/2 & Serial) the KVM switches at
+-12v. I have put it on a O'scope and looked at the signals. If you
can recommend a device, I'd appreciate it. But the real question is
during boot, can I select which mouse to use, and/or can I change it
on the fly.
Regards, Andrew
