Data Specifications

When communicating via an asynchronous serial data port (RS-232/ RS- 422/RS-485), the baud rate, number of data and stop bits, parity, and handshaking are user-selectable. Parity only applies to data transmitted by the XiII printer since the parity of received data is ignored.

When communicating via the parallel port, the previously mentioned parameters are not considered. Refer to Chapter 2 starting on page 23 to configure the communication parameters for the XiII printer. The values selected must be the same as those used by the host equipment connected to the XiII printer.

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 XiII 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.
