The block of channels varies with the power supply model.  For the 24 
way power supply, the block is 48 channels.  For the 12 way it is 24 
channels and for the 6 way it is 12 channels.

Set the Power Supply starting DMX channel by using the SETUP menu. 
If talkback is enabled on the power supply, the starting power supply 
channels are limited to 1, 4, 7, 10, 13, etc.

Fan speed (when enabled at the power supply) is remotely controlled 
with the following DMX levels:

51% to 100% -- fan at normal (high) speed
0% to 50% -- fan at low speed 
8% = fan off (when this function is enabled at the power supply)

Refer to the user manual of the various Coloram II products for detailed 
operating information on those products.

The formula for calculating DMX channels is as follows:

Example:  Color Changer DMX channel (221) = Color Changer channel  
(20) + Power Supply starting channel (202) -1

Note:  For the 24 way power supply, the Coloram II color changers can 
only be addressed to the first 24 channels of the 48 channel block of 
the power supply. 

       Note:  The Color Changers will not respond to the DMX signal until you

                        return in the "menu tree" to the RUN SCREEN loop.

Connect the DMX512 signal source to the DMX input connector on the 
front of the Power Supply using standard DMX cable. Valid DMX signal 
will be indicated by the words "DMX OK" on the Power Supply display.  
The Color Changers will now position their gelstrings according to their 
respective DMX signal levels.

The HEAD-FEET parameter is a method of accounting for the voltage 
drop in the power/signal cable caused by the current drawn by each 
color changer.
