Controlling the Display Remotely | 47
Basic Commands
Several basic commands are shown here as examples. Note that these commands are used when
a single computer connects to a single display. Contact your dealer for advanced command
specifications if you want to connect multiple displays, or perform complicated controls using other
commands than the basic commands.
Set command
Command format: Length (1 byte) + Checksum (1 byte) + ID (1 byte) + Cmd Type (1 byte) + Cmd
Code(1 byte) + Value(>=3 byte) + CR (1 byte)
Example 1: Set Brightness as 76 for ID-02 and this command is valid
checksum = (0x38)^(0x02)^(0x73)^(0x46)^(0x30)^(0x37)^(0x36)^(0x0D) = 0x33
checksum = (0x34)^(0x02)^(0x2B)^(0x0D) = 0x10
Example 2: Set Brightness as 176 for ID-02 and this command is invalid
checksum = (0x38)^(0x02)^(0x73)^(0x46)^(0x31)^(0x37)^(0x36)^(0x0D) = 0x32
checksum = (0x34)^(0x02)^(0x2D)^(0x0D) = 0x16
