Transmission / Receiving Protocol
Transmission
[Command1][Command2][ ][Set ID][ ][Data][Cr]
* [Command 1] : First command to control the TV.
(j, k, m or x)
* [Command 2] : Second command to control the TV.
* [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 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 TV transmits ACK (acknowledgement) based on
this format when receiving normal data. At this time, if
the data is in data read mode, it indicates present sta-
tus data. If the data is in data write mode, it returns the
data of the PC computer.
Error Acknowledgement
[Command2][ ][Set ID][ ][NG][Data][x]
* The TV transmits ACK (acknowledgement) based on
this format when receiving abnormal data from
