Swapped the EXM-13A with no change; going to try the EXM-14 card next. Do the monitors split from one VGA port via a cable splitter? I'm still working on getting manuals for this machine so I'm learning as I go so far, thanks for the help.

Hi Deni- Thanks for the reply. I'll try to figure out what vision system is on it. I know it has two 5.3mil cameras front and back, UPS 3.2.2c os/2. Where do I determine the type of vision system; in the computer or harware spec plate?
