[Command 1] : First command to control the set.(z)

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

[Set ID] : You can adjust the set ID to choose desired TV ID number in Setup menu. Adjustment range is 1~ 99. When selecting Set ID ‘0’, every connected TV is controlled. Set ID is indicated as decimal (1~ 99) on menu and as Hexadecimal (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/NG][Data][x]

The TV transmits ACK (acknowledgement) based on this for- mat 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]

TV transmits ACK(acknowledgement) based on this format when receiving abnormal data form non-viable functions or communication errors.

[Command 2] : use as command.

[Set ID]: use the small character, if set ID is 10, TV will send the ‘0’, ‘a’
