Basic format for control data
The transmission of control data from the external device starts with a STX signal, followed by the command, the parameters,
and lastly an ETX signal in that order. If there are no parameters, then the parameter signal does not need to be sent.
STX
C1 C2 C3 : P1 P2 P3 P4 P5 ETX
Start (02 h): 1 byte
Command: 3 byte (fixed) Colon: 1 byte Parameter: 5 bytes maximum (Length depends on Command)
End (03 h): 1 byte

Please see p. 35 regarding Commands and Parameters.
Notes
With standby mode, this TV responds to “PON” and “QPW” commands only.
Wait for the response of the first command to come from this unit before sending the next command.
If multiple commands are transmitted, be sure to keep intervals of 250msec. Send the command again when the call back
command is unusual.
If an incorrect command is sent by mistake, this TV will send an “ER401” or “ER402” command back to the computer.
This TV does not respond for 15 seconds when “PON” or “POF” commands are transmitted.
Send “EXT” commands before sending “IMS:**” commands.
DATA/MTI (RJ11) terminal connection
A standard 6 pin RJ-11C connector is used to provide a connection between the MTI equipment and the TV set. Both the MTI terminal and
TV are equipped with FCC-66 style (RJ-11C) jacks. Each of these jacks shall accept a 6 contact plug Molex P/N 90075-0007 or equivalent.
