DMX Values
If this is your first time addressing a fixture using the DMX-512 control protocol then 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.
Pan & Tilt Invert
This feature allows the user to reverse the Pan and Tilt movement on each fixture regardless of the
operating mode. Only the mirror movement would be affected by this setting. You will notice that the
fixture’s mirror home setting upon initializing would be set completely opposite of the others not set to
Invert.

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.
