4-Way Acoustically Transparent Masking - Page 28

Those might work too. You might want to verify that the IR can be used with a standard universal remote. Are you going to go with one of those boards rather than the Xantech?

I programmed my Logitech Harmony One universal remote and thought I'd post about a minor issue that I had to resolve. I don't know if this will apply to other remotes or not.

First of all, the Xantech CC12 relay responds to 4 commands:
The only command I want to use is the last one, "Momentary".

When I programmed the remote, the Logitech database had the Xantech CC12 as one of the component options so I selected it. The problem was that once you select a component the Harmony assumes that you want to turn it ON. This was a problem because every time I turned on my system the masks would turn "ON" (#1 above). I didn't want this.

To solve the problem, I simply went into the programming options and selected an option that let me tell the Harmony that this component did not have an on/off button. This stopped it from sending the "ON" command.

Yes, I bought a slightly used Xantech RC68X programmer remote (You can see a little bit of it in the video I posted). I used it to teach the codes to my Logitech. I probably didn't really need to get the RC68X but I was wanting to get the project done quickly and I didn't want to take the time to look up the codes, etc.

I've just started looking into Roomie/ iRule. Looks like a very cool solution. I will eventually move in that direction rather than the dedicated universal remote.

Here's another wiring diagram. All three shown below are essentially the same thing, just a little different format...









Note that the Xantech CC12 has a little dial in the upper left corner for a "Code Sub-Group". Each one is set to a different group so that the "momentary" command is unique for each. This way they do not all respond to the same IR command. The instruction manuals from Xantech provide details on how to set these groups.

In my diagram I show the IR going to an IR connecting block. Any major brand should work.

For most of my IR throughout my theater and home I am using Xantech. It also interfaces with my Lutron Grafik eye lighting system and I have a couple of off brand receivers scattered around as well.

When I built my theater I ran a couple of extra Cat5e wires to the my screen wall from my A/V rack/closet for IR so I have an IR receiver above my screen. The majority of my IR connecting blocks, emitters, power supplies, etc are in my equipment closet.

What IR system are you using in your theater? I would think that the CC12 should work with any major brand of IR distribution products.

I wrapped the cable around the pulley twice to gain additional friction.

Here is a picture from an earlier post. It is kind of hard to see, but the green cable is wrapped twice around each pulley.

I'm not at my theater now to measure the pulleys, but I would guess they are about 2 1/2". My suggestions would be:

1) Try bigger pulleys for more surface/friction surface.

2) Make absolutely sure that your side masking rollers spin VERY easily. Back early in this thread I have some pictures that show the roller and thrust bearing setup I have on my rollers. Before I motorized my masking, I could move the side masks with only slight pressure with two fingers. If your masking is at all difficult to move you will have problems with the motor pulley.
