U-12 Remote control (continued)
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)
