Holy smoke!

I assume you mean that your receiver didn't work on a standard console? How reliable/unreliable was it--total fiasco or just partial?

My ENTTEC (running under LightFactory, not the freeware stuff) runs the few DMX512 devices I've tried.

How did you arrive at the 44Hz (!) figure? Scope, specs, what? If it's truly that bad, I'm going to send the package back.

Can you give me a link to your code and/or schematic?

Thanks!
