RS-232 Serial Data Port
The connection for this standard interface is made through the female DB-9 connector on the
rear panel. A DB-9 to DB-25 interface module is required for all RS-232 connections through
a DB-25 cable (see
RS-232 Interconnections Using a DB-25 Cable on page 105 for details).
For all RS-232 input and output signals, the printer follows both the Electronics Industries
Association’s (EIA) RS-232 specifications and the Consultative Committee for International
Telegraph and Telephone (CCITT) V.24 standard signal level specifications.
Table 17 shows the pin configuration and function of the rear panel serial data connector on
the printer.

*9 +5 V DC +5 VDC
* This pin is also available as a +5 VDC power source at 750 mA. To enable this capability, a
jumper on the computer’s main logic board needs to be installed on JP1, pins 2 and 3.
Note • An interface module is required for RS-422/RS-485 interface support
(see RS-422/RS-485 Interconnections on page 106 ).
