Transmission

[Command1][Command2][ ][Set ID][ ][Data][Cr]

*[Command 1] : First command to control the set. (j, k, m or x)

*[Command 2] : Second command to control the set.

*	[Set ID]	: You can adjust the set ID to choose
		desired monitor ID number in option
		menu.
		Adjustment range is 1 ~ 99.
		When selecting Set ID ‘0’, every
		connected the set is controlled.
		Set ID is indicated as decimal (1~99) on
		menu and as Hexa decimal (0x0~0x63)
		on transmission/receiving protocol.
*	[DATA]	: To transmit command data.
		Transmit ‘FF’ data to read status of
		command.
*	[Cr]	: Carriage Return
		ASCII code ‘0x0D’
*	[ ]	: ASCII code ‘space (0x20)’

OK Acknowledgement

[Command2][ ][Set ID][ ][OK][Data][x]

*The set transmits ACK (acknowledgement) based on this format when receiving normal data. At this time, if the data is data read mode, it indicates present status data. If the data is data write mode, it returns the data of the PC computer.

Error Acknowledgement

[Command2][ ][Set ID][ ][NG][Data][x]

*The set transmits ACK (acknowledgement) based on this format when receiving abnormal data from non-viable functions or communication errors.

Data 1: Illegal Code

2:not support function

3:Wait more time
