Appendix C Host Computer Interface
C-13
Overview of Signals (RS-422A)
FG – Frame Ground – (Pin 1)
This pin is connected directly to the printer frame.
RDA – Receive Data Inverted – (Pin 3)
RDB – Receive Data – (Pin 18)
These pins carry asynchronous data sent from the computer to the printer. (differential input)
SG – Signal Ground – (Pin 7)
All signals can transmit between the printer and the host computer to send each signals with a signal
ground.
SDA – Send Data Inverted – (Pin 9)
SDB – Send Data – (Pin 10)
These pins carry asynchronous data sent from the printer to the computer. (differential output)
+5 V DC (Pin 11)
This line is connected to the printer’s +5 V DC line (+5 V ±0.5 V, 250 mA [Serial and Parallel total]
maximum, fused).
RS-422A interface voltage levels
The interface signal voltage levels conform with the EIA RS-422A standard. The differential voltage
varies from 200 mV to 6 V.
SERIAL Connector
The connector marked "IOIOI " (RS-232C/RS-422A) on the rear panel is a DB-25S connector. Use a
DB-25P connector (or equivalent) for the connector on the cable.
