12V on main board & 5V on expansion board: test pattern not working on exp. bd.

[thetraveller333]

I have an F16V2R with an expansion board.  Last year, I used only the main board, but this year I want to use the expansion board as well.


I'm running 12VDC on both halfs of the main board and 5VDC on both halfs of the expansion board.


I don't have it hooked up to a computer at this time.  I'm just trying to see the test patterns.


When I plug a string of 100 5VDC pixels into any of the 16 ports of the expansion board, all 100 pixels light up white and stay lit.  I tried all 16 ports.


When I try to run the test pattern by pushing the button on the main board, nothing happens.  The pixels stay lit.


I checked the wiring connections and they are all OK.


I tried the string on a small inline controller and the test patterns run fine.


I tried a 12V string on the main board and the test patterns run fine.


Questions:

   
• Do I need to connect the controller to a computer to tell it that it has an expansion board?
• Should the test pattern work on both the main board and the expansion board, even when the expansion board is on 5VDC?
• Should the pixels come on and stay on when I  plug them into the expansion board?
• Any suggestions what I could try next?

Thanks for your help.

Forgot to mention that the ribbon cable is connected between main board and the expansion board.

Connect to computer go to webpage and enable the expansion board.

Thank you David.

That worked, I forgot that last year, I set up the ports on the expansion board with zero pixels, in the port configuration screen.


All is well with the world once again.
