Serial (RS232C) Interface Pin Assignments
Pin
Name
Direction
Function
2
RD
I
RS232 received data.
3
XD
O
RS232 transmitted data.
4
DTR
O
Hardware handshake line.
5
GND
-
Logic ground.
6
DSR
I
High (“space”) = OK for the printer to
transmit data when requested. The state
of DSR is
IGNORED for XON/XOF
handshaking if selected. Dip Switch SW2
position 7 ON reconnects this signal to be
a hardware RESET input signal (normal
connection to the DTR line from a
computer will hold the printer always
reset).
7
RTS
O
Same as DTR.
