There is always discussion about the quality of DMX-USB-interfaces, so I think it is time to face this discussion with the reality. Whats more real, than oscilloscope pictures of the signal. I have done pictures of all the interfaces and consoles I could find.

We should have a complete list - so please, if your interface is not here, try to make a photo and add it.

Theory


Erwin Rol is explaining the DMX timing very good on his website - the following picture is from this this site - the important part of the signal is around the break - so I tried to catch this part with the oscilloscope
