Maximum Lr for this Command

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:
