Enttec Open DMX USB and DD-100 28021 dmx decoder

[PatDelaney]

Using a DMX console (hardware), I am able to contol the intelligent 5050 smd 2801 pixels via the DD-100 dmx decoder. So I'm pretty sure my wiring is ok.

The hardware controller has 16 on/off switches (DMX 1-16)

Turn on sw 1 -results red LED comes on in pixel 1(as expected)

Turn on sw 2 -results green LED comes on in pixel 1 (as expected)

Turn on sw 3 -results blue LED comes on in pixel 1 (as expected)

and so on, so I know I havew communication.

If I swap the hardware controller with Open DMX USB and XLights nothing seems to happen.

By default the strip shoud go to black if it senses a DMX signal. But that doesn't happen.

If I remote the DD-100 decoder and the 5050 pixel strip with a 3 channel dmx module and an simple RGB strp the stip goes dark and connected, and when I start xlights I can control the RGB strip.

Note that the DD-100 I has is actuall mislabeled as DDP-100 but RAY WU swears its correct and It does work with hardware

What am I missing?

here are my notes:

Intelligent Pixel Strips: (5 Volts) DMX1 = Blue, DMX2 = Green, DMX3 = Red 3 Ch. per Pixel x 32 pixels = 96 DMX Channels

Pixel Strip (5 volt LED’s)
