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. 

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. 

To connect to an IBM PC, you can use these Intermec cables: 

•  25-pin printer to 25-pin serial port null modem (P/N 048668) 

•  25-pin printer to 9-pin serial port null modem (P/N 048693) 

You cannot order an Intermec cable for the RS-422 interface, but there is a 
schematic on page 94 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. 

Turn the On/Off switch to the off position. 

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

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

If necessary, change the PC serial port configuration to match your 
printer. See “Configuring the Serial Port for Communications” on page 
12 for more information. 

If you are using a parallel port to communicate with your printer, you 
need a parallel cable to run between the printer and the PC. 

You can purchase a parallel cable from Intermec (P/N 051211) or from 
your local computer store. See page 70 in Appendix A for pin descriptions 
of the parallel cable connector.
