2
<06>
Bytes to follow
3
<B1>
Command = Flag
4
<d#>
Device Number Device Number of Lamp section of module
5
<b#>
Bus Number Bus Number of Lamp (hex)
6
<07>
Type = Set Color/Bright
7
<dt>
Data = Not Used <00> for this command
8
<dt>
Data = Intensity <00> to <0F>

4
<d#>
Device Number Device Number of Lamp section of module

6
<07>
Type = Set Color/Bright
7
<dt>
Data = Red / Green 1st 4 bits = RED value (0 to F hex) 2nd 4 bits = GREEN value (0 to F hex)
8
<dt>
Data = Blue / Flash Rate 1st 4 bits = BLUE value (0 to F hex) 2nd 4 bits = FLASH rate (see below)
Flash Rate Notes
0 = Default Restores default lamp function (ie lamp is illuminated if that is the current fader state)
2 = Slow On/off cycle = 1 second
3 = Medium On/off cycle = 0.5 second
5 = Fast On/off cycle = 0.25 second
The follow example will set the Fader 1 button to maximum RGB values and fast flash:
02 06 B1 0B 11 07 FF F3
TIP: This command format has changed from v1.x firmware, to support the FLASH rate.
The new format has 4 bits for RGB colors (0 to F) followed by the flash rate.
TIP: This command allows the lamp to flash, even if the channel is off. This is useful for
EOM or ready indicators. On reset to no flash, the lamp returns to its correct state.
