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.
If XON/XOFF handshaking is used, the only signals that the printer requires are the RXD,
TXD, and GND signals. If the hardware handshaking is used, then the CTS and RTS signals
Note: Verify that the printer’s On/Off switch is switched “off” before
plugging in the power cord into the electrical outlet and the power
supply’s output cable into the printer.
