The special serial cable has two very different plugs. The small, round plug on
one end connects to the Printer Unit. Refer to the diagram below for the location
of the Serial Port on the Printer Unit and then plug the special serial cable into
the correct port. Rotate the serial cable until the pins line-up with the holes in the
serial port. DO NOT FORCE THE CABLE INTO THE PORT.
Next, attach the remaining end of the special serial cable to your computer’s
serial port. Refer to your computer’s manual for the location of the serial port.
Generally, the serial port is near where your printer or other parallel device
connects to your computer and just below where your keyboard and mouse
connect. DO NOT FORCE THE CABLE INTO A PORT IF IT DOES NOT FIT
EASILY. Ensure the thumbscrews on the special serial cable are securely
tightened before proceeding.
