Serial Interface (Option)

Installing the optional serial interface board kit (IB-11) in the printer enables connection to a
computer with an RS-232C standard serial interface.

Interface voltage levels
The voltage levels of the interface signals conform to EIA RS-232C specifications. The voltage level
of SPACE is 3 to 15 volts. The voltage level of MARK is -3 to -15 volts. Voltages between -3 and 3
volts are undefined.

Description
Frame Ground. This pin is connected directly to the printer
frame.
Transmit Data. This pin is used to output asynchronous data
sent from the printer to the computer. This signal is often
used in handshaking.
Receive Data. This pin is used to input serial asynchronous
data sent from the computer to the printer.
Request To Send. This output is always high (above 3
volts).
Clear To Send. Not used.
Data Set Ready. Not used.
Signal Ground. This pin is used to establish a common
reference level for the voltages of all signals other than
Frame Ground.
Data Terminal Ready. This pin is used to notify the status of
the printer buffer (i.e., nearly full or nearly empty) when
handshaking is used. The pin goes high (above 3 volts)
when the buffer is able to accept more data.
