Mitsubishi Electronics MDT651S manual Remote control

U-11 Remote control (continued) Carry out as necessary

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.

NOTE:

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.

	Address code			Function code	Data code	End code
HEX		30h 30h		Function	Data	0Dh
ASCII		‘0’ ‘0’		Function	Data
[Address code]			30h 30h (ASCII code, ‘0’ ‘0’), fixed.
[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 (In ASCII code, ‘ ’) fixed.

3)Control sequence

(1)A command is sent from the computer to the monitor. (Commands should be sent at intervals of at least 600 ms.)

(2)The monitor sends a return command within 600 ms* after receiving and encoding the command. If the monitor fails to receive the command, it doesn’t send any return command.

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

(4)The monitor sends various codes other than the return code. While RS-232C control sequence is in progress, reject other

codes on the personal computer side.

*: Transmission of the return command may be delayed during signal switchover, etc. Example: Turn the power ON (‘ ’ is for ASCII code)

Command from computer	Command from monitor	Detail of command
30 30 21 0D		Command for POWER ON
‘0’ ‘0’ ‘!’ ‘ ’
	30 30 21 0D	Command received
	‘0’ ‘0’ ‘!’ ‘ ’	(Command echoed back)

For RS-485, both of DTR and RTS lines remain Active Low while the TXD command is sent from the computer.

4)Operation commands

The operation commands configure the basic operation settings of this LCD monitor. The commands may not work during signal switchover.

The operation commands have no data codes.
