In this example, let's analyze the message of the communication protocol.
To change the Contrast of the screen mode to 90, you have to define a packet as follows.
First, find the Contrast command from the Command List.
Find OxOB for PICTURE.
Find Ox02 for CONTRAST.
Find OxOO for CONTRAST.
Finally, insert the desired value 90 into the 4-byte data.
Insert the header values Ox08 and Ox22, calculate and insert the check sum and send the packet to the DLP DTV.
e.g.) PICTURE / MODE / CONTRAST (90) CS= -(08+22+0B+00+01+5A)+1

If the DLP DTV receives, analyzes and parses the packet successfully, it transmits a Success packet to the PC.
