Interface Signals
The pins of the printer’s RS-232C interface connector carry the signals
listed in
Table B.3
. The table also indicates whether each signal is
incoming or outgoing with respect to the printer.
Table B.3 RS-232C Signal Pin Assignments
Brief descriptions of the signals follow.
FG - Frame Ground - (Pin 1)
This pin is connected directly to the printer frame.
TXD - Transmit Data - (Pin 2)
This output carries asynchronous data sent by the printer to the computer.
It is used mainly in handshaking protocols.
RXD - Receive Data - (Pin 3)
This input carries serial asynchronous data sent by the computer to the
printer.
RTS - Request To Send - (Pin 4)
This output is always held high (above 3 volts).
CTS - Clear To Send - (Pin 5)
DSR - Data Set Ready - (Pin 6)
Unused.
