Problems with my LEDWiz

[Dudeman]

Ok... I'm bumfuzzeled.

I've been working on getting one of my CPs wired for LEDs. I've gotten them all wired up and when I hook it up I cannot get it to work right.

First, I hooked it up to an external PS because on this panel I'm running 40 LEDs and I didn't want to tax the capabilities of the board.
This is what I get (minus a few LEDs. I couldn't get them all on my drawing):


All the lights come on regardless of what the LEDWiz is doing.

The I decided to forget the external ps and just use the LEDWiz. So then I get this:



Lights do nothing... regardless of the LEDWiz.

So I hook up ONE LED to test if this thing even works. I use the LumaAura control for GGG to turn on #16 and I get this:


I turn off #16 and get this:


So far so good, but...
I turn on #15, and get this!!!!


What the  !??!!!?!?!!

Also, here is a pic of my LEDWiz:


I know it looks like a freaking mess. Some will say that must be the problem, but I've tested every pin (twice) to make sure nothing is shorted together.
The box has 3 different connectors, 1 for each CP.

I will try and help. I just installed my first LED Wiz and it was a learning experience. We did get it working correctly though:) With help from RandyT at GGG.

What we did is we took a 5volt from the power supply (with an inline fuse from radio shack) and ran that to a terminal strip (right term?) Image below of what i mean.

We then hooked the red wire of the led to the terminal strip and the other led wire to each input of the LED Wiz. So each LED is wired to 5 volts on the terminal strip and to the LED Wiz

We then wired the voltage banks together, this is what RandyT said to do. What I mean is we took a small piece of wire and hooked 1-8 8-16 16-32 so they were all wired togther. We did this becasue we dont have anything but LED's on the Led Wiz and they only need the 5 volts for each bank. Then we ran a wire from one of the voltage banks and ran it to the terminal strip.

The LED's I used are the Nova Gems from GGG.

Hope this helps. And hope I explained it right!

That is pretty much the way I have it hooked up. I talked to Randy and he said I broke it.

Oh bummer

I said quite a bit more than offering just that as a possibility.  Did you, as I suggested, extract the unit from that massive amount of wiring to make sure that the issue is with the LED-Wiz and not a wiring error of some nature?  

There's really no other way to know, and there's much anyone can do to solve the issue while it's still buried in there.

I didn't mean to say that you didn't give any suggestions or weren't any help... just that I was the idiot who probably broke it. I could have stated that better.

I intend to extract it from it's cocoon of wires this weekend and try it again, but I'm very confident in my abilities to break something.

My parents wouldn't let me play with anvils for that reason.

When you put it back together try to mount the LED Wiz on top of the wiring if possible. It makes it much easier to use a meter to check connections etc.

[Dudeman]

How many connections do you have in each of those boxes? I see you are driving the LEDs of the USB power from the LEDWiz board.

[Franco B]

All 32 ports are used.

There are four 15 pin d-subs in each enclosure. I used the top row of eight pins from each d-sub for the 32 ports and I bridged four of the seven pins in the bottom row to supply the 5v to each bank of eight.

Yes you are correct, in the pictures they are configured for 5v from the USB but I have bridged the 5v input wire since then.
