Transmission [Command1][Command2][ ][Set ID][ ][Data][Cr] * [Command 1]: First command. (j or k) * [Command 2]: Second command. * [Set ID]: You can adjust the set ID to choose desired product ID number in Special menu. Adjustment range is 0 ~ 99. When selecting Set ID `0', every connected TV set is controlled. Set ID is indicated as decimal (0~99) on menu and as Hexa decimal (0x0~0x64) 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 Product 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.
