fixture template for LED lights with no intensity channel
Posted 24 January 2010 - 06:36 AM
Need some help to write a fixture template for the pat pad and a LED lamp fixture which has no single intensity channel - just 3 channels for each color
Basically channel map is
1 = red intensity
2 = green intensity
3 = blue intensity
4 = strobe effect
5 = fade in/out effect
6 = control channel
I want to be able to control overall intensity (for whatever RGB mix set on the pad-pad) with the Maxium Fader... Because of the way the Maxium templates work - they expect an intensity channel for the desk fader - not 3 separate dmx channels.

If you have the latest v3.xx software installed in your console then there is a way to create a virtual dimmer channel for the LED fixtures. Any attribute that you want to be connected to the Virtual Dimmer (yellow fader) just needs the lower case letter i inserted before the name (see sample below, but do not use the bold font when you insert the i into your template).
name = i"RED"
channel = 1
homeVal = 255
So you can have any channel/s assigned to the virtual dimmer, such as RDG, RGBA, RGBAW, etc.
There is a sample template on the download page under "Generic" brand called "RGB LED" that has this all working. I have attached a copy for your use as well.

As an FYI to others reading - I needed to upgrade to the latest software 3.3 as version 3.01 didn't work, and also had to delete and re-load the template into the library to get things working.
One thing I have noticed is I can't seem to get the LED lamps to black out when the fader is at 0% and /or the pat-pad values are set to 0 also. Not sure if it is something I have done or another issue... will post a reply if I solve.
Have also uploaded the template file in case anyone else is interested too.

However on some very cheap fixtures the dimming is not at all linear and this level of ~0.3% on DMX can result in the fixture putting out 10-20% light output. There is not much we can do about this, it is the way the fixture is designed, and whilst we are clever we cannot work miracles
