When a SWM capable receiver is connected to the SWM and powered on, the SWM assigns one/two of it's available channels to that tuner (or tuners if the receiver is a dvr) If a receiver is connected that would supass the capability of the SWM, the SWM simply doesn't assign an output channel to that tuner. So, only the first 8 tuners connected and powered on would work. There would not be an intermittent issue.
To me, this sounds more like either a potential grounding issue or possibly a power inserter going haywire. Just my $.02
I asked this question on my last post then read another and got the answer. Thank you for that input.
I just got into the MDU a month or so ago. I have one complex in the Houston area. 15 customers one service call that was of no fault of the system itself. The system along with the flexability of the SWM8 makes this maybe the most awesome thing I have ever had the pleasure of working with.
