Transmission
[Command1][Command2][ ][Set ID][ ][Data][Cr] * [Command 1] : First command to
control the Monitor.
- [Command 2] : Second command to control the Monitor.
- [Set ID] : You can adjust the set ID to choose desired monitor ID number in optionmenu.
Adjustment range is 1 ~ 10.
When selecting Set ID ‘0’, every connected set is controlled.
Set ID is indicated as decimal (1~10) on menu and as Hexa decimal (0x0~0x0A)
on transmission/receiving protocol.

ASCII code ‘0x0D’ - [ ] : ASCII code ‘space (0x20)’
[Command1][Command2][ ][Set ID][ ][Data][Cr] OK Acknowledgement
[Command2][ ][Set ID][ ][OK][Data][x] The Monitor 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 status 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 Monitor transmits ACK (acknowledgement) based on this format when receiving abnormal data from nonviable functions or communication errors.
