ok...I've been after my suppliers for a while to try and solve this for me, but they haven't been able to find what I need. And, time is running out so I turn to the list. Have an embedded PC *gasp* running DOS, and the keyboard and monitor needs to be around 20' from the instrument. First, anyone know if there is a limit to the distance for driving both, and second, an extension cable for video and PS/2 AND a bulkhead adapter for PS/2 ? Oh..suppose it is not totally unrelated to PIC, as there is a PIC in the overall design of the instrument... :-) private email is probably better than cluttering up the list. I think I set it so a click on reply will come back to me direct
