Question Beamworks DA 6500K 4 pin timer/controller question

I just buy a Beamsworks DA 6500K and the controller. Really happy with the quality of the light and the timer/controller work perfectly but I realize to go further by being able to dim the fixture base on the hours of the day to get a more natural lighting and control the amount of light my plant receive. The timer/controller sadly cannot do that, the light are on/off and always 100% output.




• After searching the internet I decide to go with the TC420 Programmable LED Time Controller — TC420 Programmable LED Time Controller



My question is about connecting the dual (Blue/White) to the TC420

My thing is that I do not want to cut the Beamswork fixture wire either on the Power supply side and the Light controller side.

For the power supply I want to use something like that. The size seem to have been tested OK with Beamswork —> 5.5 X 2.1mm Barrel Power Plug 12V DC Cable Connector Male Female with Pigtail for CCTV Security Camera LED Strip
— See on that post —> https://www.plantedtank.net/forums/10...ng-no-co2.html

• I think it should be easy?


For the Light controller/timer (plug on the other side that the power supply) it is another matter


The light controller/timer have a 4 prong connector that seem to be compatible with these cables — LEDJump Black 18AWG 4 Pin Waterproof Male Female Connector Cable RGB LED Strip with Rubber at —> https://www.amazon.com/LEDJump-Water.../dp/B00BTN6CI6

The problem is to know what pin (4) do what to be able to connect it to the ? tc420

Anybody know ?

Anyway to test it ?

you don't use the timer plug at all, THOUGH some have reported only intermittent issues of using the timer and a TC-420..
That said, i'm pretty sure one could use it but...

Easier just to ignore the "2 channel " timer thing and just jack in from the power supply to dimmer to light head using mating barrel connectors..
Run a separate timer to the power supply..

since all the timer does is make or break the 2 channels a simple voltage reading between prongs to find the 2 "pairs" would be interesting..

Could have 2 channels w/ the TC-420..
Not sure how it handles the switch though..

anyways it's been done dozens of times the "old" way..

Manual dimmer..not tested but there are dozens of like units..

i am using this https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 with my da fspec. the barrel connectors are a perfect match (only cannot use the locking nut).

The beamswork will not easily split the 2 channels into TC-420 inputs because they are common ground, not common anode. I suggest you get an inline dimmer and basic wall timer.
