I have a house with (9) Universal MX-850's and (10) MRF-260's in it. I am having a problem with cross talk, where 1 remote can control another area's receiver. It doesn't happen all the time, but it tends to happen if a person in one room is pushing a button, and at the same time someone else is pushing a button in another room. I have changed the ID's, routed the IR to different outputs and it still occurs. Has someone else seen this problem?

Thanks

Haven't seen this issue myself. I assume that each MRF-260 has its own ID (something other than "0") and that each MX-850 has been assigned the corresponding ID for each in MXEditor. Also, are these are all newer (within the past year and a half) manufactured MX-850s with narrow band transmitters?

Mike...assuming install/programming is perfect...I've seen this before in a coach we did where one remote would open up the RF from a button press and during that extremely brief moment a button press on another remote would get through. Almost as if during this brief moment the ID is ZERO. This was with 2 remotes and 2 RF kits...not that crazy setup the OP has which obviously leaves alot of room for installer error. I for the life of me can't remember how it was resolved and haven't run into it since, I'll talk with the installer who contacted URC.

The remotes have all been purchased in the last few months and they are all post Nov 2006. None of the remotes are using ID (0) and they all work great. There just seems to be some interference between them, especially when (2) or more are throwing commands at the same time. It is mostly Vol +, Vol - and ch +, ch -. I spoke with Universal and they suggested getting the receiver away from the plasma, and also removing the antennas to restrict range. Has anyone seen plamsa's interfering with the receivers, and moving them away changed anything? Or has anyone removed the antennas?

Thanks

Have you tried setting up the problematic RF kits to have different IR outputs from the other kit that is also having the problem?

i.e. Bed TV is having the above listed issues with the Bath TV. Enable IR routing on the programming for both and set IR route for Bed TV to say 1 and IR route for Bath TV to say 3?


Yes plasmas will interfere with all kinds of other devices...I doubt it would cause the problems you are having since you claim that each device works great by itself.

Removing antennas was something we started doing back in the good old days of the mrf-250 and carried over to the somewhat less than reliable mrf-300 (compared to mrf-350). Removing the antenna on the mrf-300 yielded FAR superior results but limited the range a bit.

We don't use the mrf-260 at all so I can't comment on that piece. We use the mrf-350 and msc exclusively with URC systems.

I agree with tweeterguy that it's not likely the plasma's the cause. Haven't had to remove an antenna from an MRF-260, but it looks like in your case (with the number of remotes and base stations being used) that none of them ever get very far away from a base. Removing the antenna to restrict range might at least reduce, if not solve the problem. Also, tweeterguy's suggestion about making sure like devices are on different line numbers couldn't hurt.

For what it's worth I spoke with the installer regarding this same issue he was having on the coach. He contacted URC and they had no answer for him other than what I presumed in post 3 here and I believe at least one other time on this forum. The solution for this appication was to swap one of the DTV receivers to a different brand so as to not have conflicting commands...obviously this may not solve your problems with all of the gear you are controlling with so many rf kits. Take the advice given in the posts here and get back to us.
