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 specifi cations.
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’), fi 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 (In ASCII code, ‘
’) fi xed.
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)

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 confi gure the basic operation settings of this LCD monitor. The commands may not work during signal 
switchover.
  The operation commands have no data codes.

5) Read command
  The computer sends the command without datacode to the monitor.
  After receiving this command, the monitor returns the command with datacode including the current status to the computer. 
  Example: When the computer asks the power status of the monitor, and the status of the monitor is powered-on.

LAN Remote control
By connecting the monitor and the computer using a network device such as a L AN hub as shown in Section P-7 and making 
the network settings using the OSD menu and RS-232C communication control, you can perform remote control using the same 
commands as those for RS-232C.
1. Setting procedure
(1)  Set the following network parameters using the OSD menu. (See page 47.) 
  • ON/OFF, IP address, subnet mask, gateway mask setting, and default gateway of DHCP client
(2)  Send the same control command as that for RS-232C via TCP/IP socket communication.
(3)  Check the status sent from the monitor. When it is received successfully, the setting is completed.
