RS-422/RS-485 Interconnections

To connect the printer’s RS-232 DB-9 interface to a host computer through an RS-422

or an RS-485 interface, an interface adapter is required (Zebra part number 33130).

The illustration below shows the required cable wiring for interconnecting to the

interface adapter’s DB-25 female connector.

Note • A jumper on the computer’s main logic board needs to be installed on JP1,

Pins 2 and 3, for the RS-422/RS-485 interface adapter to function properly.
