RS-422/RS-485 Interconnections

Caution • A qualified service technician must install a jumper on the printer’s main logic board at JP1, pins 2 and 3, for the RS-422/RS-485 interface adapter to function properly.

An interface adapter (Zebra part number 33114M) is required to connect the printer’s RS-232 DB-9 interface to a host computer through an RS-422 or RS-485 interface. A generic DB-25 adapter can be used. Figure 39 shows the cable wiring for interconnecting the DB-9 to the interface adapter’s DB-25 female connector.
