DMX Mode
In this mode you will be able to control each individual trait of the fixture independently. The LRG-55
occupies 8 channels of DMX control. For detailed listing of the DMX channel values refer to the
Appendix section.

This DMX mode enables the use of a universal DMX controller device. Each fixture requires a "start
address" from 1 to 511. A fixture requiring one or more channels for control begins to read the data
on the channel indicated by the start address. For example, a fixture that occupies or uses 6 channels
of DMX and was addressed to start on DMX channel 100, would read data from channels: 100, 101,
102, 103, 104, and 105. Choose start addresses so that the channels used do not overlap and notate
the start address selected for future reference.
If this is your first time addressing a fixture using the DMX-512 control protocol than I suggest jumping
to the Appendix Section and read the heading “DMX Primer”. It contains very useful information that
will help you understand its use.
Set the start address using the group of DIP switches located usually on bottom of the fixture. Each
dip switch has an associated value. Adding the value of each switch in the ON position will provide
the start address. Determining which switches to toggle ON given a specific start address can be
accomplished in the following manner. By subtracting the largest switch value possible from the
selected start address which does not cause a negative number.

Resolving address
using simple math.
Address 233
233 – (128) = 105, Turn ON Dip # 8
105 – (64) = 41, Turn ON Dip # 7
41 – (32) = 9, Turn ON Dip # 6
9 – (8) = 1, Turn ON Dip # 4
1 – (1) = 0, Turn ON Dip # 1
You will most likely use the first
available number which maybe number
1. This number was selected for
example purposes.
