Turning on the DVB receiver I noticed change on C band signal.
I dont know how it was set.
Can't use DC block. This isn't serial, but parallel connections. The Ku LNBF on this BSC-621 must get power to work.
Update for today:
Seems to be working. I have C band running, I'm watching the ex-Spike TV channel on G0-19, and DVB is on G10R's RTN channels.
When I turn on the DVB box, I get more "sparkles" on the G0-19 channel, but I really dont care as once I get this finished up, it'll be all on one TV and both boxes will not be used at the same time.
As a test, it would be very interesting to put the splitters in, with one leg DC blocked to see if this BSC621 continues to operate (I suspect it will not). |
When I was referring to a DC block, I was talking about having both the Ultra and the Ku side of the 920 hooked up on Ku, either via passthru or via splitter, in which case a DC block is necessary on one receiver, and the power comes from the other one.
But I see what you're doing anyway, ie just have the Ultra alone on Ku. The interesting thing is that this lnbf is intended to be used with it's internal switch, and most external switches don't pass DC to the port that isn't selected. Although perhaps the switch that's inside this LNBF does pass DC to both lnbs. I know that you aren't using the internal switch, I was just thinking about how it was intended to work if you DID use the internal switch, which would be to have the same voltage on both LNBs. However since you're NOT using the internal switch, you could be putting different voltages on the two lnbs, as well as to the 2 sets of polarity probes. I just have to wonder if due to it's design, it might be confused when it has different voltages applied to it??? Just a thought, but it might be interesting to change polarity on the DVB unit while watching the C-band side.
