Pixie 16 voltage swap issue

Recommended Posts

So here’s my deal. I have two Pixe 16 controllers that I had hooked to 5v power supply’s for my Halloween display. During my swap out for Christmas  I had to change the power supplies out for 12v since all of my Christmas props are 12v. The HM is seeing the controllers but none of the lights will work while running test on them. Is there something I may have missed?  I don’t see why I’d have to do anything while from just changing over the power supplies. Any help is welcome. I’m done messing with them for the night. I’ll give it another try tomorrow. Thanks in advance.

i'm not sure of the Pixie 16, but did you just disconnect the 5V supply and then wire the 12V supply to the same terminals?  I think each power supply is connected to different areas on those boards.  So if you happen to put the 12V on the 5V line, you may have let the magic smoke out of some of the components on your Pixie 16 and may need repaired.   I know most of these type boards usually have 2 separate sections, one for 5VDC and the other for 12VDC.

Just know most dual supply boards, each voltage is separated, and putting the wrong voltage on the wrong line, especially higher voltage on the lower voltage can do some damage to components and even lights connected to the device.

Like stated, most boards I've seen have this type setup and I think I read the Pixie series isn't any different in this respect.

Good Lucj.

What Gen Pixie16?

Do you have the flashing status light and if you do what happens when you open HU up and refresh the "search for unit ID"?

Did you try resetting the board?

Did you connect the PS to the Logical Input terminals? that's the key, sounds like you connected to the incorrect terminals.

Check your fuses?

Pixie 8 and 16 just have 2 banks. You can run them at different voltages (5V on one bank, 12V on the other)  but there is not an input difference per voltage.

Same terminals for either 12v or 5 v on the pixies. However for power in from PS has to be connected 2 logical terminals

Logical is the ones that power the electronics on the board as well as its bank. The other only powers its bank.

If your power supply can handle the attached loads, jumper the + to + and - to -

If you run 2 supplies, be sure the - of each are bonded (the Pixie may do this (I don't own one with 2 banks, so I can't verify)

Yes they do. A while back I posted my dual PS Pixie16 to show someone. Yes, both banks need to be tied in.

I would assume if the OP removed the PS he could simply replace. My next assumption is he purchased assembled controllers and not used to building them.

Thanks folks, more info to add to my collection so i know the next time.   Just know when I worked in Electronics about a hundred-million years ago{sure seems like it too me! LOL}, anyway, dual voltage boards always had 2 separate terminals for each voltage level needed.  And each had to be ISOLATED from the other.  How things have changed over the last several years.

Even CMB24's from LOR are different. The Lights can run at 5V, then you need a 12V wall wort attached to the round jack, to supply the board logic. (the pixies don't have the need)

No wonder even us seasoned electronics folks get confused in THIS HOBBY of ours now days!🤣

I think my board just gave out. Swapped out the board and the new one is fine. The New style pixie 16 have two separate banks. You can actually run both 5v and 12v on the same controller so long as all the lights use the same protocol. One side would be 5v and the other would be 12v. My previous board was all 5v for Halloween but for some reason when I switched to 12v it didn’t like it. Oh well. All is good now.
