DB-9 Connectors
Printer Interface Technical Information
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. The
illustration below shows the connections required for the DB-9 to DB-25 interface.
Note • The cable used to connect the printer to a computer must be a null modem
(crossover) cable. If you want to connect the printer to any other DTE devices, you
must also use a null modem cable.
