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.
