Kyocera FS-600 Overview of Signals RS-422A, RDB Receive Data Pin RDA Receive Data Inverted Pin

Serial (RS-232C/RS-422A) Interface (Option)

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 signals with a signal ground.

RDB – Receive Data – (Pin 18)

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 6V.

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.
