Steve's LED's and Standard PWM RA

[robmwpropane]

I have a "Steve's LED" kit that I put together a while ago. It has 4 drivers (each has 3 arrays of 7) and a total of 84 LED's. I was planning on connecting the drivers to the dimming ports on the RA.

Is this ok? The manual doesn't state any limit, but I want to be on the safe side...

Thanks!

I've heard of people that have done it.
I think the signal is PWM.

I'm not so sure...I think Steve's are 0-5v PWM

As per this post; http://forum.reefangel.com/viewtopic.ph ... s+per+port

the RA is 0-10V?

Damn...?

Edit: This is on Steve's Website:

-Aquarium controller compatibility - YES! Any aquarium controller with 0-10V dimming can control this driver using Steve's Aquarium Controller Harness. For this driver to accept a 0-10V input, Steve's Aquarium Controller Harness is required.

Double Damn.....

The RA can be all those different settings. The ability will depend on how old your relay box is. You have other options too.

It's 2-3 weeks old. Still has that new electronic smell! How can I change it?

You can add the dimming expansion module.
It allows you to configure the signal to either 0-5V or 0-10V. You can also choose PWM or analog.
So you have all 4 options to choose.
The relay box is fixed at 0-10V and comes assigned PWM or analog when you purchase it.

Yes, I know about the dimming module, I did not know the RA was 0-10v. To be honest, I didn't know there was 0-5v or 0-10v. I thought there was only analog or PWM.

Is there any other option besides the dimming module? Some sort of programming to limit it to 0-5v, or using an ATO port? My question might be silly, but I honestly don't know...

[rimai]

Yes, the ATO ports can be used as 0-5V PWM.

I hate to ask, but I can't find a link anywhere? Any pointers?

Basically you need to add a code like this:

Code: Select all

pinMode(lowATOPin,OUTPUT);
analogWrite(lowATOPin,PWMSlope(8,0,18,0,5,50,60,5));
pinMode(highATOPin,OUTPUT);
analogWrite(highATOPin,PWMSlope(8,0,18,0,5,50,60,5));

Awsome!, Thanks, will give it a read this weekend...

Just wanted to add to this thread, I did confirm Steve's drivers are 0-5v PWM for anybody who's looking for info.

Just following up, I bought the 6 channel dimmer module and got everything connected over the weekend. Works perfect, I did it this way because I wanted control of of all 4 channels and hence color.
