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 page 62 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 8 shows the pin configuration and function of the rear panel serial data connector on the
