[QUOTE="deeptho, post: 1134347, member: 215446"] A33, sounds plausible. At least in this case the receiver was not at fault because the voltages were still there. The LNB is inverto, the switch Spaun. So, nothing exotic. I should use scope to inspect the current. The voltages looked like this (at the receiver side). You can clearly see the various 22khz bursts ending in a continuous 22khz signal. Perhaps due to the long cable and/or the large capacitors you meantion, it takes about 400ms for the DC voltage to stabilize. The diseqc commands are sent while the voltage is still settling, but that works. [ATTACH type="full"]144560[/ATTACH] The motor specs state that it can go up to 350mA, and at least according to a multimeter, it does not exceed that much (the highest was 380mA). The only thing the specs say about the current limit is that there is one. [/QUOTE]
