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

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 37 shows the connections required for this cable.
