NX Touch.. no DMX output!!

Hello, Just got the NX Touch. Onyx sees it no problem and all the buttons/ faders seem to work fine, but I have no DMX output at all… my lights are not detecting any dmx


Do You have any DMX tester?
Can You check maybe in Diagnostic mode is any DMX coming out of the device?

I do have the same problem with a M-touch, It was working normally and suddenly without any reason it stopped to send DMX signal.
