You can add me to the list of people having RF problems with the MRF-250.
When I first plugged the MRF-250 I noticed the status light was solid red... not flickering.. but solid. I then switched it to ID1 and the light went out. At first I was thinking the switch was actually changing the frequency but after reading today I found that ID0 simply disables addressing. So basically ID1 is still getting blasted with noise only the status light doesn't show it.
Now that I know that ID0 is sort of a test setting I am going to go around the house on a hunt for a noise free spot.
To make a long story short.. When extending the emitters can I make the negative side of all the emitters common so I can get all 6 emitters on one Cat5 run?
Also, does anyone have any advise on cabling all my stuff? I have a big mess of cables. I know I have some abandoned stuff in there I can strip out but is there any way of bundling the cables in some sort of shielded conduit to help reduce RF noise?
