3.2.2 RS232 Serial Communication Interface
The printer provides a 9-pin female D-Sub connector, on the rear panel, for RS-232 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 3-1 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 hardware CTS handshaking.
The CTS and RTS signals are required when using hardware flow control. The other
signals are offered in the event that the host computer would require them.
