IBM EasyCoder 3400e Connecting Your Printer to a PC, Connecting the Printer to a PC Serial Port

Getting Started 1

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.
