RS-232C Remote control
By connecting multiple LCD monitors and a computer using RS-232C  cables (commercially available), you can control the monitors 
from the computer for the following operations: 
  Power ON or OFF
  Switching between input signals
  Volume control and mute
  Auto setup
  Check of the internal temperature of the monitor, etc.
Connection
  Before making connections, turn off the personal compute r and the monitors.

  This LCD monitor uses RXD, TXD and GND lines for RS-232C cont rol.
  Use RS-232C cables of reverse type (commercially availabl e).
2)  Control command diagram 
  The command is structured by the address code, function cod e, 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 singl e 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 speci   cations.
  To use terminal software, send a text   le with control com mands. The monitor is not compatible with the sending of 
commands using a keypad.

receive the command, it doesn’t send any return command.
(3)  The computer checks the return command to see that the co mmand 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)
