I run stuff in upper closets very often. Most laundry
rooms have 2 extra cat5es above the cabinets for instance.
On a recent project the electrician thought I was crazy
for some of the places I asked for power. I want power
there in case I need an access point or whatever could
come down the line...

Thnx Roddy.....by upper closets, do you mean closets on the 2nd or 3rd floors for retrofit purposes? Or do you mean just wire and mount them high up in the closets themselves. Or does both essentially apply? : )

I've done stuff in laundry rooms for APs and such as well and got the same strange looks. Too funny...

Cool, thnx for the input....much appreciated!

This sort of topic came up recently in either this forum
or the URC area recently and then kind of died. But
I'm curious.....in regards to running extra cat5 for more
433s....where do you guys normally plan to place the 433
or additional/redundant 433s. The last one we did we
placed two rfx-250s in the attic space above a large gameroom
(one on each end). However, this house is a foamed house
so the attic space doesn't get that hot, even though it's
in Texas. I would not have felt comfortable putting
any rf antenna module in an unfoamed attic as it would
melt around August here in Texas.


Would you guys mind sharing where you typically physically
locate most of your antennas? Bookshelves? Attic space?
Kitchen cabinets? Behind FPDs?


Thanks in advance, Roger

We have always run extra CAT5 for the 433s. Generally we use closets and pantries with placement above the door or cabinets. Once as a last resort we ran it behind the display.
I'll let you know tomorrow..

I don't know if you guys understood the true meaning of my original question. I wasn't referring to the distance that I can get the RM-433 to respond from the remote but the actual maximum distance between the RM-433 and the RP6.
I'm always right. The only time I was wrong was the time that I thought, that I was wrong.

Nardo1,

thnx for the reply....If you don't mind me asking, how did the one behind the display work for you? Was it URC or RTI?

Thnx, Roger

I never had a customer complaining about this but I was just thinking about this today. What are the chances of collision, in a layout with multiple RP6s and RM-433 wire out together, when more than one remote sends a trigger at the same time and both signals are picked up either by the same antenna or another scenario could be two signals that are output to the IR bus at the same time by two different RM-433.

RTI. It did the job. We placed several around the home and found an area where response was not ideal. There was extra CAT behind the 42” we installed so we used that.
I'll let you know tomorrow..

I sure didn't think that's what you meant! I just reread it and it was clear as a bell the first time. roddy's answer veered off into remote/RM433 distance, and that's all I saw after that!

I'm going to guess that when RTI sends product out in semi trailers that they are quite comfortable sending them across the stinkin' desert without specifying refrigerated units, nor even specifying that their stuff has to be on the bottom away from the heat from the sun. Since RTI stuff generates hardly any of its own heat, I think you could relax about that. Or, heck, call 'em up and see how hot a room they can be in!
A good answer is easier with a clear question giving the make and model of everything.

I am pretty good at going off topic, even when I am trying to help out.. lol

I have put RM433's on the 3rd floor and had the main processor 2 floors down in the basement. Probably with the wire run you are looking at a good 75 fee distance between the antenna and the processor.

Roddy, I know you are now in NC on vacation but have you ever noticed a collision issue, when more than one remote triggers a code at the same time in a configuration with several antennas and one or more than one RP6s tie together?

Actually they have the temp range in the manual.. Based upon that recommendation we have avoided putting them in the attic. (Arizona)

Several of our projects have 100+ feet of cat 5 between the RP-6's and the RM-433 modules. The most RP-6's on 1 single job I have used is 5 with 6 RM433 modules all tied together via 1 continuous run cat 5. If you put RM433's in the attic try to put the module as close the drywall ceiling as possible, and let the antenna portion poke up throught the insulation, this reduces the amount of heat and cold it will be exsposed to.

I did not notice any collision factor to be honest. For instance all 3 kids sat boxes are on one R-6 and they have never complained that they had trouble changing channels. There are a couple of shared TiVo's and an Escient DVD controller also in the project.

I have not purposely hit 2 buttons at one time though...

It is an issue that it is really hard to recreate. Unless you do it on purpose, the probability of this happening is highly unlikely but it would be interesting to know what the results could be.

The results are likely to be no command issued by either system. The user is unlikely to notice it because it will happen about once every 17,384 years in normal use, and if it does, they will likely just hit the button again and not even remember it.
