Connecting Your Printer to a PC

You can connect your printer to either a serial port or parallel port on your PC. You
must provide the correct cables for connecting the printer. See the following sections
for cable information. Contact your Intermec representative for ordering assistance if
you do not have the appropriate cables.

Connecting the Printer to a PC Serial Port

To connect the printer to your PC serial port, you need a
shielded EIA RS-232, RS-422, or RS-485 electrical interface
with a 25-pin D-style subminiature connector. It must have
pins on the printer end and an appropriate serial port
connector on the other end.

Use the following table to determine the correct Intermec
cable for your application. You cannot order an Intermec
cable for the RS-422 interface, but there is a schematic in
Appendix C that you can use to purchase or make your own
cable. Also see Appendix C for the RS-232, RS-422, and RS-
485 serial port pin assignments.

1. Turn the On/Off switch to the off position.

2. Plug the 25-pin connector into the serial communications port on the rear of the

printer.

3. Plug the other end of the cable into a serial (COM) port on the PC.

4. If necessary, change the PC serial port configuration to match your printer. See

“Configuring the Serial Port for Communications” later in this chapter for more
information.
