RS-232 Interconnections Using a DB25 Cable

In order to connect the printer’s RS-232 DB9 interface to a DB25 connector, an interface adapter is required. A generic DB25 adapter may also be used, however the +5VDC signal source would not be passed through. Figure 39 illustrates the connections required for the DB9 to DB25 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.
