Enter the following code:
0xbe, 0xef, 0x10, 0x05, 0x00, 0xc6, 0xff, 0x11, 0x11, 0x01, 0x00, 0x01

Header [H] ==> Fixed, “be (Low Byte), ef (High Byte)”
Address Code [AC] ==> Fixed, “10”
Size of Payload [SoP] ==> Byte size from MsgID to Command Code, “05 (Low
Byte), 00 (High Byte)” or Byte size from MsgID to Value, “06 (Low Byte), 00
(High Byte)”.
CRC16 [CRC] ==> CRC value, “c6 (Low Byte), ff (High Byte)”
MsgID [ID] ==> Fixed, “11 11”
MsgSize [SoM] ==> Byte size of Command Code, “01 (Low Byte), 00 (High
Byte)” or Byte size of Command Code and Value, “02 (Low Byte), 00 (High Byte)”
Command Code [COMMAND] ==> “Power On” Command, “01”

Projector Response Message Table

Byte0 value:
0x00: Success
0x01: Invalid Command (on the control command list but no valid)
0x02: Error Command (includes CRC error and unknown commands)

Projector Response System Status

Byte0, Byte1, Byte2
Byte0: 0x00 (Success)
Byte1: 0xff (the Command Code of System Status)
Byte2: Return status
Ex: When the projector is in standby mode, the return status will be 0x01.

Projector Response Lamp Hour
