Hi folks, please confirm that all four remote controls in all four rooms will be able to control all equipment in all four rooms?

For example, the MX980 in room #4 should be able to control the TV in room #1!??

Each of the four rooms will have an MRF-350 + RXF-250 daisy chained.
Does room #4 MRF need to plug into room #1 MRF to complete the chain?
Not sure if the in/out are full duplex.

The daisy chain MRF-350 is for RF. IOW, one RFX-250 can be daisy chained to two or more 350 and/or MSC-400. The IR In is just distribution to all flashers.

If you have 4 RFX-250's then there is no need for a RF daisy chain.

If room 4 remote can be received by room 1 RFX then program room 4 remote to have device TV send control to room 1's 350 address. If have duplicate TV's in those rooms then duplicate the TV's in the remote and set the address for each TV.

If it were me I would set room 1's 350 to address 1, room 2 to address 2 and so on.

Thank you. Seven posts in 17 years. I feel l privileged! :)

I don't know if just three RXF-250 (max per MRF) will be enough for all four rooms. But it probably would be. My house isn't massive in size.
So, I think this is what you're talking about.

Start from the top. How many remotes do you have? How many MRF-350's? How many rooms? Devices in each room?

Hi, four remotes, four MRF-350's and four rooms.
Each room has its own device(s).

Actually, I only have three MRF-350's but was going to buy a 4th.

OK. You have 4 separate systems in 4 separate rooms. But you said you want each remote to be able to control all rooms.
WHY!!!!
That doesn't make any sense.
What are you trying to accomplish?
Is there more we don't know about? Maybe a common source is feeding all the rooms?

The quick answer is that I want to be able to turn on/off all TV's & Audio in all rooms, no matter what room I'm in.
It may end up getting more complicated the further I get into this.

As far as common sources go.....

There's an HDMI video matrix dealing HDMI for multiple sources to each room.
And a multi zone audio amplifier.

1) Ideally, what you are wanting to do is really beyond the capabilities of a URC CCP system. This is more the territory of URC Total Control - so you also would be looking at 2x the cost of equipment to do everything. Plus you have to be a dealer to even program anything in TC - no consumer is going to be able to get TC software, it's hard enough for dealers to stay approved.

2) With the above said, depending on your equipment brands you want to control, it maybe possible to do this with CCP in a very unconventional way. It is going to involve running a lot of IR signals over Cat5/6 between rooms, not the RF. Breakout boxes with diode isolation. And a bit of trial & error.

3) The easiest way to deal with this however, is not worry about turning other rooms off & on when you are not even in them.
BUT.... since you said you have an HDMI matrix involved.... could the reason you want that kind of control be because the Matrix won't work correctly unless all the TVs are on together? I have seen that with some of the cheap crappy HDMI matrix before.

Hi Brad, I'm cool with running Cat6 all around the house.
Just spent a couple hours in the attic tonight doing just this.

Do not have Dealer access.
Just my consumer login for CCP access.

This is a lot to try and cover in a forum board but lets begin.

1st, need a detailed layout of what we are working with. Specifically brand & models of 'every' piece of equipment involved (at the very least the brand):

Where is the central components located (matrix and sources)? Is it in room 1, 2, 3, or 4? Or is it located in another (5th) room?
What size matrix is it (i.e 4x4, 6x4, etc.). What sources do we have connected to it? How is the output from the matrix getting to each TV (long HDMI, cat6 over extenders, etc.)?
How is the multi-zone amp getting its audio and from where?
Are there any other sources going to the TVs, that's not coming from the matrix?
What is the longest approximate distance from the central equipment and the furthest room?

I'll start a diagram based on these answers, and prepare the next set of questions.

Thanks for any suggestions, Brad.

Room 1 =
  • 4x4 HDMI matrix (goes to AVR, PJ and two HDMI splitters)
  • Primary HDMI video source (HTPC)
  • Secondary HDMI video source (Nvidia Shield)
  • Denon AVR
  • Projector
  • Wall-control for whole-house amp with IR control

Room 2 =
  • TV with IR
  • Two computer monitors, which I haven't quite figured out how to turn on/off since they have no IR. But they do power on/off with AC on/off.
  • Six channel whole-house amp with IR remote & RS232 and each channel can be turned on/off remotely.
  • Wall-control for whole-house amp with IR control

Room 4 =
  • TV with IR
  • Two computer monitors, which I haven't quite figured out how to turn on/off since they have no IR. But they do power on/off with AC on/off.
  • Wall-control for whole-house amp with IR control

Room 3 =
  • TV with IR
  • Wall-control for whole-house amp with IR control

The HDMI matrix inputs are HTPC, AVR's output (VideoProcessor) and a VM

Well, that's a scattered mess!

For the dual monitors in the 2 rooms. If it is acceptable to have them turn on/off with the TV, then you can use a smart strip to control them with the power of the TV = [Link: amazon.com]

If you need individual control, then you can use IR controlled relays. Then have the relay switch power to the monitors (this will require splicing AC cords) = [Link: amazon.com]

Some multi-zone amps will have a wired IR input on the chassis, with discrete codes for each zone. Others might have a wired IR input on the back of the room keypads. You didn't give the make & model of this amp, so I'm going to guess we are dealing with a really cheap POS. So it has no special connections or controls beyond the keypads. That will make things difficult to control this.

Same with the HDMI matrix. Have no idea what we are dealing with and how it is controlled. So nothing I can suggest yet for that.

Are all the TVs the same brand? - so same IR code with work them all? or different brands and different IR codes? So 1 IR port could be used to control them all? HAVE to know these things.

Regardless of how the commands are distributed, this will involve some l-o-n-g running macros that will tie up the controlling remote for a while.

I hope that there are not too many power toggles.

Until he lets us know at least the brands on everything, we won't know what might be involved.
Also hasn't said what distances are between the rooms yet, so unsure what kind of wire might be best to use for extending IR signals and control relays. Sounds like we could need as many as 3 pulls to each room from room 1 - depending on how he wants to control those monitors.
