3.2.2

RS232 Serial Communication Interface

The printer provides a 9-pin female D-Sub connector, on the rear panel, for RS-232D serial
communication. The printer is configured as DCE (Data Circuit-terminating Equipment) so a
NULL modem cable is not necessary. A serial data cable is required to use serial
communications, refer to Table 3-4 below for correct cable configurations.
The factory settings, unless otherwise requested, are set at 115200 baud, 8 data bits, 1 stop
bit and no parity with both hardware and software handshaking enabled. The baud rate is
user selectable from 110 to 115,200 and uses software XON/XOFF flow control and/or
hardware CTS handshaking.
