I am building a HT which will have a MidAtlantic rack system for my AV equip (for anyone who may not know, those are open racks with no door at all in the front).
I bought the 890 because my rack will be located on a side wall and there will be a bar to the rear and left of the room. I need to control the equipment from anywhere in the room even though I will have almost no direct line of sight.
I personally dislike using the stick on emitters in an open rack so I am thinking of building a small shelf which will overhang the front/top of the rack onto which I will mount the RF receiver upside down. (Okay, long winded set up)
Here's my question: How far should the shelf overhang the top of the rack in order for the RF receiver to be able to "hit" all of my components? The rack is a total of 29" tall and it will have various components throughout that height. In a related question, do the IR emissions emanate from the tip of the receiver? the side? the top?, other?
Last question, I didn't know until I perused this forum that there is an 890 Pro. Can anyone confirm that the standard 890 uses Zwave signals? I bought some dimmers assuming this remote would control them natively but now I am not sure.
Any help you can give from your experiences is greatly appreciated. Thanks.
I think you might not be clear on how the RF extenders work.
The RF extenders are an RF receiver with IR emitters attached via a wire (4 connections, 2 emitters each, 8 devices).
You run the wires to the devices and the IR nodes stick to the device (via peel off sticky). You mount each emitter over the IR receiver on your device.
The RF extender converts the RF signal from your remote to IR codes issued by the nodes.
So you can mount the RF extender anywhere on your rack (I have a middle atlantic rack as well). I mounted mine up near the top in the rear. I ran the IR cables down the back and they emerge above/below the device it controls.
If your rack is tall and you have devices near the bottom, the IR cord might not reach. All my IR devices are middle to top of my 44 space rack so it wasn't an issue.
Also, set up your remote and make sure it's working for a few weeks before 'mounting' it for good. When you make changes to the remote you need to connect the RF extender to your PC to sync the changes so you will need access to it. One solution there is to have a USB hub on the rack and run the extenders USB cables to the hub (but only one could be attached when you sync). That way only the hub needs to be accessable.
