So I bought 3 - 16" basic SB reeflights and nodded them for Apex control. I have spent more than $2500 on my SCA 150 before I bought the Apex. So I've decided to wait awhile to drop $800 on the Apex and decided that I would try a Kessil Spectral controller to control my modded SB reeflights.
The Kessil appears to output a 0-10v signal on 2 channels (color-ch1, intensity ch2). To my dismay the Kessil did nothing to change the intensity of either channel. I thought maybe I did something wrong and I went over and over the wiring. I rewired every combination I could. Only 3 wires for control circuit with 2 going together in all combinations. I finally thought about using a constant known voltage to test the modded wiring. I used a AA battery hotwired to a 3.5 mm cable with the end cut off and the other end in the lights. The light dimmed to approximately 15%.
The question is the Kessil outputting a PWM 0-10v signal and that's why it's not working or am I missing something?
Would a reef-pi solve my problem or is that also a PWM signal which may also not work?
I have the skills and some extra parts (resistors, wire, soldering iron, circuit boards) to build the hardware part of a reef-pi but it's the coding that has me hesitant to try that route. That and the 7000 post thread of technical jargon to read through which I only understand about half of.
Thanks in advance of any help.
