DB-9 to DB-25 Connections

An interface adapter is required (Zebra part number 33109M) to connect the printer’s DB-9 interface to a DB-25 connector. A generic DB-25 adapter CAN be used, although the +5 VDC signal source would not be passed through the adapter.

Figure 37 shows the connections required for the DB-9 to DB-25 interface.

NOTE: Pin 1 of DB-9 connector is unused and unterminated.

Modem Connection

When the printer is connected via its RS-232 interface to Data Communication Equipment (DCE) such as a modem, use a standard RS-232 (straight-through) interface cable.

Figure 38 shows the connections required for this cable.
