I have very limited experience with Time Warner. I noticed on the back of their boxes there are 3.5mm IR inputs. Do these work?

This would be very area dependent, as the firmware the provider is using will dictate if the feature is active or not.

If it is active, that plug is a stereo (3 wire) plug. You would need to unplug the box, plug in a stereo cable with the ends stripped, plug box back in and turn it on, then use your multi-meter to find with connection has the voltage for the IR receiver on it. Then chassis ground. And of course the last one would then be IR in.
Still won't know if the IR signal it wants to see is with carrier or stripped until you experiment.


The other way is to wait and see if someone here has already done all this and can give you the answers to the above.

These boxes don't really like IR emitters either. They are way too sensitive.

On a recent job, I turned down the output on the MRF350 as low as it would go, and I had to mount the emitter on the shelf about 5 inches away from the box.

Placing the emitter on the box wouldn't work at all.

I've had to put a dab of electrical tape witwia pinhole in it between the flasher and the box to get it to so changing channels 2-4 at a time. Just about any work around you can devise to counter their power toggle issue, they are sure to make it obsolete with equipment change or firmware update. I'm fairly certain making CI lives into nightmares is in their mission statement
One thing I have learned in this industry. It is easier to pull a wire than it is to push one.

Well, I'm using video sensors to solve the power toggle problem. But the boxes not liking flashers is a bigger problem. Especially since I have three boxes in a rack.

Blank face plates on a shelf, and the cable boxes sitting backwards on the shelf so you can mount the emitters on the lacing bars. One box at the top of the rack, one in the middle, and one at the bottom so you don't get any cross talk could work.

Then again, maybe a 4" to 5" tube, like a toilet paper roll core, taped to each individual box and the emitters taped to the tube?


I tried the pinhole thing and had no love.

I will fire up this system on Monday or Tuesday, aned see how the boxes respond. I'll keep all of this in mind once I see how the boxes are working. Of the 3 in the rack, each one is a different model. Two different Samsung boxes and a Cisco. So the solution will probably be different for each one.

Many materials that appear opaque to the human transmit IR. I use aluminum foil as the blocking agent. Then I use tape to hold the foil, and perhaps to hide the foil from view.

In a rack environment, it may be possible that enough IR leaks out of one unit to control another. You may need more than a dot of foil to control this.
