Hi all, I'm trying to build a network enabled DMX controller. If I attach the DMX shield directly to my Uno R3 it works fine with the basic DMX blink sketch and the shield connected to a 4 channel DMX lighting controller. However if I plug the Ethernet v2 shield in and the MDX shield on top of that I can't get any output from the DMX shield. Uno appears to be running the sketch as the serial light is still flashing just no output. AFAIK the DMX shield only uses D2 output and Ethernet shield uses D4 and D10-13. Anyone have experience with this? Thanks!

Ethernet Shield v2:
. The underside of the Output XLR socket on the DMX shield was shorting out on the metal housing of the ethernet port on the ethernet shield. Have munged together the simple webserver example and DMX blink examples and both working fine.
