I have recently purchased a cad-cam solution that has post processors for the Bridgeport EZ-Vision Converse. Can anyone tell me how I can port the pc to the control unit to upload g-codes? I don't see a DB25 parallel port like the EZ-Trak. Do I connect using the usb ports or ethernet port instead? I see a serial port, but I'm assuming it is to connect another display. Any help would be greatly appreciated, because our shop would like to get past the "canned" cycles that it comes with.
