Hello,

I can. I have one (KPS-7AS) sitting here and it works fine.

It depends on what you are trying to do. The port on the CPU has two functions, a 'loader' port and a 232 port.

K200SOPERATORMANUAL.pdf -- "Please refer chapter 13.3 for detail pin-out of RS-232C connector."

Or does this not help?


Good luck,

Mark
