How to Use

Remote control

RS-232C Remote control

When the monitor is connected directly to a computer using an RS-232C cable (commercially available), the following

operations can be controlled via a communication. Select the communication interface (RS-232C) used for the serial

communication function. (See page 58.)

● Power ON or OFF

● Switching between input signals

● Volume control and mute

● Auto setup

● Check of the internal temperature of the monitor, etc.

For connection with a 25-pin serial port connector on the computer, a conversion adapter (commercially available) is required.

1) Interface

PROTOCOL RS-232C

BAUD RATE 9600 [bps]

DATA LENGTH

8 [bit]

PARITY BIT NONE

STOP BIT 1 [bit]

FLOW CONTROL NONE

● For direct connection using RS-232C, use the RXD, TXD, and GND lines.

2) Control command diagram

The command is structured by the address code, function code, data code and end code. The length of the command is

different for each function.

•This example shows a basic command that is used when a single computer and a single monitor are connected.

When you want to connect multiple monitors or perform complicated control using other commands than the basic commands, contact your dealer for

advanced command speciﬁcations.

•To send commands with a keypad using terminal software, select “2s” or “30s” for CONTROL TIME OUT in CONFIGURATION2 in the OSD menu.

(Follow the same procedure for LAN control.)

Address code Function code Data code End code

HEX 31h 30h 34h 38h Function Data 0Dh

ASCII ‘1’ ‘0’ ‘4’ ‘8’ Function Data

[Address code] 31h 30h 34h 38h (ASCII code, ‘1’ ‘0’ ‘4’ ‘8’), xed.

[Function code] Code unique to each control function.

[Data code] Data unique to each control function (Not always indicated by

numerical values.)

[End code] 0Dh (ASCII code, ‘ ’) xed.

3) Control sequence

(1)The command is structured by the address code, function code, data code and end code. The length of the command

is different for each function.

(2) The monitor sends a return command within 600 ms* after receiving the end code. If the monitor fails to receive

the command, it doesn’t send any return command. (*During the power-on/off or input selection process, the

transmission of the return command may take more than 600 ms.)

(3) The computer checks the return command to see whether the command it sent was received or not. The computer

must receive the return command before sending the next command.

(4) The monitor sends various codes other than commands including the return command. While RS-232C control

sequence is in progress, the computer must reject the codes.

Example: Turn the power ON (‘ ’ is for ASCII code)
