Communication Protocol

Transmission
[Command1] [Command2] [ ] [Set ID] [ ] [Data] [Cr]
[Command1]: The first command to control the projector (k. j, x, m, n ASCII code, 1 Character)
[Command2]: The second command to control the projector (ASCII code, 1 character)
[Set ID]: You can adjust the set ID to choose desired monitor ID number in option menu. Adjustment
range is 1 to 99. When selecting Set ID '00', every connected set is controlled. Set ID is
indicated as decimal (1 to 99) on menu and as Hexa decimal (0x01 to 0x63) on transmission/
receiving protocol.
[Data]: To transmit command data (hexadecimal).
Transmit FF data to read status of command.
[Cr]: Carriage Return - It corresponds to ASCII code '0x0D'.
[ ]: ASCII code 'space (0x20)
OK Acknowledgement
[Command2] [ ] [Set ID] [ ] [OK] [Data] [x]
* The set 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.
