DB-9 to DB-25 Connections
An interface adapter is required (Zebra part number 33109M) to connect the print engine’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 53 shows the connections required for the DB-9 to DB-25 interface.
