❑Communication Protocol

1.Transmission

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

*[Command 1] : First command to control the set.(k, j, x, ASCII code, 1 Character)

*[Command 2] : Second command to control the set..(ASCII code, 1 Character)

*	[Set ID]	: You can adjust the set ID to choose desired projector ID number in special menu. See previous page.
			Adjustment range is 1 ~ 99. When selecting Set ID ‘0’, every connected projector set is controlled.
*	[DATA]	: To transmit command data. Transmit 2 character when organized ASCII code.
			* Transmit ‘FF’ data to read status of command.
*	[Cr]	:	Carriage Return
			ASCII code ‘0x0D’
*	[ ]	:	ASCII code character correspond to “Space Bar” which is in order to classify command, set ID and Data.

2. OK Acknowledgement

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

*The Projector 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.

3. Error Acknowledgement

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

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

Data : [1] : illegal code(This command is not supported.)

[2]: not support function(This function doesn’t work.)

[3]: wait more time(Try again a few minute later.)
