I need to move the PC about 24 ft from the controller - in another room. So, I installed a CAT-5 cable (about 48 ft in length) from the controller to the PC and soldered the 9-pin connectors on ensuring pins 2, 3, and 9 are wired correctly. When I run the shopbot supplied loop back tests - everything works wonderfully. Unfortunately, it still does not want to talk with the controller. Any ideas on what I could do to get them talking?
