Establishing Computer
Communications
If, after having followed the procedure in Computer on page 90,
communications cannot be established with a computer, the problem
may lie with the hardware connections or the printer cable
configuration.
To establish communications with your computer:
1. Ensure 2020 is connected to the serial port of the
computer.
The serial port will usually be a male connector,
typically 9 pins on computers. The serial port may also
be a 25- pin connector on a computer.
The 25 (or more) pin female connector is usually a
parallel port. However, there are exceptions to this rule.
2020 cannot be connected to a parallel port unless you
are using the serial to parallel converter. (Part No.
MX380145).
If you do not have a free serial port on you computer
and you want to connect 2020 to the parallel port, you
will need the serial to parallel converter. Connect 2020
to the serial port on the converter and then connect the
computer to the parallel port. If the port on the
computer is anything other than a female, 36 pin
Centronics connector you will need an adapter in order
to use the cable supplied with the converter. See
