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.
