I have just purchased an MRF-300 unit and am having problems with the IR emitters. No matter what I do they will not work any of my units. I have tried turning them from all the way up to all of the way down, moving them closer and farther away but they still only very intermittently work anything. I tried the emitters from my MRF-250 hooked to the MRF-300 and everything works perfect. Also are the MRF-300 emitters supposed to look like they are lighted up? Anyone have any ideas?

1. Is the light on always or when the commands are being issued....

2. What are your components.....Placement is critical on some pieces...

3. Do you have a bad emitter in the bunch thats shorted out and rendering all emitters useless.

4. Do you have a remote with this setup .....<-----obviously....but you didnt say which

5. Are the IR/RF signal path designated correctly and is the IR blaster set to on or off.

6. What is the Unit ID set to on the RF base......Anything but zero otherwise youll get all RF that happens in the area...

More info will yield better answers

On only when command is sent.


12 different units. Emitter will work some only if set to full on and put right in front of the IR sensor. Other units nothing no matter what.


No.


2 MX-3000 and 2 MX-800.


Have tried different settings in editor for blaster does not make any difference. As far as the correct emitter # being used I have set all for #2 for test purposes and yes I have also tried 1 - 6 too.


No RF interference. Unit ID set from 1-6 were tried. No difference.


As I said the emitters from my MRF-200 and 250 both work perfect on the MRF-300. Just a pain in the ass to cut and replace the plugs and reset all of them in case.
I just find it hard to believe that all six emitters are crap. I also tried the MRF-300 emitters on my MRF-250 & 200 and unless they are right in front of the unit being controlled they do nothing. It is as if they are just too weak no matter what I have the output set to.

You could have a bad batch of emitters..........but Im with you on that not being likely...

How do you have 12 pieces and only 6 emitters..............I didnt think they came with doubles...........please clarify.....


Any chance of getting a replacement MRF300 to test.....that seems to be the common....

Otherwise all that I posted would be what I would have tried...........

PS>other emitters will work with the MRF300 like Niles as far as I have known....in case you have a few of these laying around......

Let me know...

They work but just seem to be too weak to work right. I can take the MRF-250 emitters and move them 6 feet away and they will still work all of my units.


Two units stacked on top of each other with emitters on doors of cabinet in middle of units.


Not without buying another one.


No other ones available to me at this time. Looks like I am going to have to cut and replace the plugs on the MRF-250 or the MRF-200 emitters. Too bad because they are also brand new and I hate to do that and then not be able to sell them.

My guess is that they made the lowered the output of these to avoid oversaturation of pieces within the same location...........Just a guess, but thats seems logical....

When has it ever been about a logical choice???


Did you have any Niles Flashers to try before you cut...........

Good luck

There is no way that the emmiters from a MRF-200 or 250 will work with the MRF-300. They have smaller connections for the MRF-200/250 then the standard sized MRF-300, so how you were able to swapp emmitters is a mystery to me.

Unfortunately no other emitters to use.

Ever hear of adapters or just using clips and wires to connect the two pieces??

Interesting note. The MRF-200 emitters are different from the MRF-250 ones which are the same as the MRF-300 emitters except for the plug. I tried the MRF-250 emitters and they also work crappy with both the MRF-250 and MRF-300 units. I just assumed the 250 and 200 were the same until I actually took them out of the box. So I would assume that URC has lowered the output of the newer emitters and made them look cooler by lighting up when used. Kind of a stupid move considering they have adjustments on the MRF-300 to turn them down already.

The MRF-250's emitter outputs are 2.5mm while the MRF-300 uses 3.5mm, my personal preference.

Check that you've set the address of the MRF to something other than zero and programmed the remote to reflect, also make sure that the minipin for the emitters are full seated.
