Why won't my Plasmacam establish a connection to my parallel port? I have an older Dell, but it's not super old. I have even installed two different ports into the expansion slots and enabled them each separately to try them. I understand that their addresses are found in the devic manager and not BIOS. I have made sure the hex addresses are correct, and followed the correct sequence for turning on the computer and control module. Does the plasma cutter need to be hooked up for the computer to connect to the Plasmacam? Thanks in advance if anyone can help.
