Hi all I think - not shure that I have the same Demux - I d need manual -operation and if availiable maintenance (Circut) I had the problem with the batery (accu) it was defect- I put a zehner diode instead the accu in it because without Battery it did not work anyway. But now when the demuxer is powered on display apears and everything is OK intil i disconnect the DMX signal and the demuxer comes with some channels on - not the same as DMX was. See pictures if it is the right board Thanks
