Overview of Signals (RS-422A)
FG - Frame Ground - (Pin 1)
This pin is connected directly to the printer frame.
SG - Signal Ground - (Pin 7)
All signals can transmit between the printer and the host computer to send
each signal with a signal ground.

RDA - Receive Data Inverted - (Pin 3)
These pins carry asynchronous data sent from the computer to the printer.
(differential input)
SDB - Send Data - (Pin 10)
SDA - Send Data Inverted - (Pin 9)
These pins carry asynchronous data sent from the printer to the computer.
(differential output)
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
