6)Protocol

From the computer to the display

(1) When sending one command at a time:

STX (02 hex) ID (2 Byte) COMMAND (3 Byte or 6 Byte) ETX (03 hex)

(2) When numerical direct commands are possible:

STX (02 hex) ID (2 Byte) COMMAND (3 Byte) ARGUMENT (3 Byte) ETX (03 hex)

COMMAND: 3 Byte (ASCII)

ARGUMERNT: 3 Byte (ASCII)

(3) Echo back

STX (02 hex) COMMAND (3 Byte or 6 Byte) ETX (03 hex)

When the received command is a numerical direct effect command, numerical data is returned.

STX (02 hex) COMMAND (3 Byte) ARGUMENT (3 Byte) ETX (03 hex)

When the received command is invalid, ‘ERR’ is returned.

STX (02 hex)

ERR (3 Byte)

ETX (03 hex)

 

 

 

When the received command cannot be processed (when PON is received, when the power is already ON, etc.), ‘XXX’ is returned.

STX (02 hex)

XXX (3 Byte)

ETX (03 hex)
