Title: DMX Mosfet receiver
Post by: denneyp on Apr 29, 2014, 07:01 pm
Hi has anybody seen anything like this?

I am trying to use a tinker kit DMX receiver to interface between a DMX desk and a motor controller. The problem I am seeing is that the PWM signal output is to say the least a bit odd. With the DMX desk disconnected I am seeing a full voltage range (12V) 200 hz square wave. When the DMX is switched on it overlays the Square wave. The only thing I can think is that the software on the board is corrupted and if so does anybody know where the original code for the board can be sourced from?

Thanks in advance
