Something to look out for...
I have an EtD connected to a smart hub, the smart hub is connected to a bunch of SSCv4 controllers. The same hub is connected DMX to a DMX wireless TX transmitter.
I have floods connected to an RX, I have LEs connected over the same channel to a separate RX, and another set of controllers using one more RX -- all the same channel.
Everything has been working fine for a couple weeks.
Tonight none of the DMX attached controllers worked -- no floods, no mini-trees, etc.
Yes, the pixelnet controllers worked.
I looked at the LEDs on the TX -- red power = ON, green DMX activity = FLASHING,
I looked at the LEDs on each RX -- red power = ON, green DMX activity = FLASHING,
so, apparently enough DMX activity existed to drive the wireless activity LEDs.
I power-cycled the TX and each RX with no success.
I powered-cycled the smart hub, and the DMX started to work.
So... it seems that the PIC and the DMX-generation can get out of sorts... a power-cycle fixes it.
