RS-232 Interconnections Using a DB-25 Cable

To connect the printer’s RS-232 DB-9 interface to a DB-25 connector, an interface adapter is required (Zebra part number 33138). A generic DB-25 adapter may also be used, however, the +5 VDC signal source would not be passed through. Figure 46 shows the connections required for the DB-9 to DB-25 interface.

Note • Use a a null modem (crossover) cable to connect the printer to a computer or any other DTE devices.
