Example 1
Set the backlight level of monitor at address 0.7 (group 0, address 7) to 130 (0x82):
Monitor at address 0.7 (group 0, address 7) has acknowledged the new backlight level
130 (0x82):
Example 2
Send an invalid “BRT” command to the monitor at address 0.7 (group 0, address 7).
The command has two data bytes, but “BRT” accepts only one byte:
Monitor at address 0.7 (group 0, address 7) has not accepted the command. Instead,
it sent a negative acknowledge with the current backlight level 128 (0x80). The
length of the response message exceeds the specified value 9, because of the invalid
data field length:
