RS-232/RS-422/RS-485 Serial Data Port
The connections for these standard interfaces are made through the DB25S
connector on the rear panel. 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.
The following table shows the pin configuration and function of the rear
panel serial data connector on the printer.
