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

VDC signal source wo uld not be passed through. Figure 36 illustrates th e 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.
