Verifying the Setting

The procedure described below should be followed to verify that the RS-422A mode had been correctly set.

1.Make sure the power switch is off. Plug the power cord into the printer and turn power on.

2.When the printer is on-line, press the STATUS key.

3.If the mode has been correctly set, "RS-422A " should be indicated on the status page printout. Please refer to the sample printout shown below.

If RS-422A is indicated here, the setting was successful.

Interface Signals

The pins in the printer’s RS-422A interface connector carry the signals listed in Table C.3 .

Table C.3. RS-422A Signal Pin Assignments

Pin	In/out	Signal	Description
1	–	FG	Frame ground
3	In	RDA	Receive data Inverted
7	–	SG	Signal ground
9	Out	SDA	Send data Inverted
10	Out	SDB	Send data
18	In	RDB	Receive data

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)
