Communication procedure
Send the control commands from the computer via the RS232C terminal.
The LCD Monitor operates according to the received command and sends a response message to the
computer.
Do not send multiple commands at the same time. Wait until the computer receives the OK response
before sending the next command.
Command format
Response code format
Normal response
Problem response (communication error or incorrect command)
When more than one code is being sent, send each command only after the OK response code for the
previous command from the LCD Monitor is verified.
Note
When using the computer control function of the LCD Monitor, the LCD Monitor operating status
cannot be read to the computer. Therefore, confirm the status by transmitting the display commands
for each adjustment menu and checking the status with the On-screen Display. If the LCD Monitor
receives a command other than a menu display command, it will execute the command without
displaying the On-screen Display.
Commands
Example: The AV input mode set to PAL after switching the display mode to AV1.
