Mine is similar. Just setup as a test right now.
From this picture I don't see power to the terminal block for the pwm

Yup. Currently you have no power running thru the pwm circuit. You only have the board powered

Your wiring is correct from what I see. You don't have to power the breakout board via separate terminal. You need it when you use it to power the electronic load directly (like servo motors or led that's directly hooked to the board)in your use case you only need it for control signal, I.e. your light has a dedicated power source .
Your configuration is wrong, this is due to me changing code recently, check my example couple of post before , that usesjacks instead of channels . or just wait till I finish the refactoring, by weekend and then you can use the UI directly toconfgure channels.
Do you have a 10v powersupply? If not you should get one,since you have to convert the 5v pwm to 10v.

Ranjib, since you are refactoring the UI, do you this this is a good time to start the API doc? If you want to, you can shoot bits of information to me here on by PM and I will start a document. Your choice.

From your clip of the config file, it looks like yours. Is enable PWM set true at the top of the config file?

disconnect wires from the pwm terminals (ground and PWM)
apply 5 volts and ground to the terminal block.
intitiate reef-pi and go to equipment tab.
adjust slider on one channel to 100%.
test on PCA between ground and pwm terminals. you should have 5v.
set to 50% on reef-pi test again you should have 2.5v

If you look at the picture of my set up you will see that I have the block powered by the pi (black and white). You can pull 5 volts and ground from pi for testing purposes

@Ranjib are you saying that the pwm signal is powered from the pi connection via vcc, and the terminal block is only a power supply for the V+ buss? I guess when looking at it as servo based that would make sense to me....
@Brad Cox what version of reef-pi are you running? Evidently I am running a now "old" version, although I will say it has been very stable for lighting.

I am using .07 i believe. How can i make sure?@Ranjib are you saying that the pwm signal is powered from the pi connection via vcc, and the terminal block is only a power supply for the V+ buss? I guess when looking at it as servo based that would make sense to me....
