View Full Version : Open Light Dimming Module

Does anyone know what the output connection cable is for the dimming module to me kind of looks like a rj45 from the manual picture but nowhere is it stated.
Thinking of using it to hook up to a maxspect gyre via the Ice cap interface to control the gyre

dbond I dont have that module and there seems to be two or three different models of T5 Modules, ACQ440 / ACQ441 and there seems there was an older model before that.

Here is a post I found from a Russian guy about the connector on what I think is older model if your models connectors matches the one he shows in his link on the last post then you probably have the same module. two of the pins are for a 12V supply and 2 pins are for 0-10V control output.


Also the manual for the 440/441 model is here.

This model seems to be made to specifically work with AQT lights ACQ502.
I guess if you have some knowledge of electronics and a multimeter, you could adapt it to work on any lighting system.

Hope this helps, if not post back and let me dig some more.

Thanks I think the model I will order is the AACQ445 its description seems to be best and will try to figure out which pins are what with a meter, the powerhead I'm trying to control
just need to vary the 0-10v to vary the speed.

BTW that last post were he says the 12V polarity does not matter, is dead wrong. You need to make sure you get the 12V polarity right before plugging in the adapter or the module will be toast. After that it;s easy to figure out the ground and +10Vdc side for the T5s by using a volt meter.
