DB-9 to DB-25 Connections
To connect the printer’s RS-232 DB-9 interface to a DB-25 connector, an interface adapter is
required (Zebra part number 33109M). A generic DB-25 adapter can be used, although the
+5 VDC signal source would not be passed through the adapter.
Figure 44 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 45
shows the connections required for this cable.
