Hi, I have 2 jobs where I have installed a CBus DMX controller for the first times. Both are controlling 3 zones each of LED strip and work perfectly most of the time. However every so often it becomes totally unresponsive. If I remove the CBus RJ45 from the DMX controller effectively powering it down and plug it straight back in it then works again often for a few weeks before then failing. Does anyone know why this might be happening and a possible fix. Thanks in advance Mike
