Hello, first time poster, also new to Ocelot/IR extension products.

I'm able to successfully send signals from the Ocelot via emitter to a TV. I'm also able to successfully use my remote control to tranmit signals through the powermid tranmitter to the powermid receiver which sends the signal to the TV via emitter.

The problem comes when I send the Ocelot signal to the Powermid transmitter via emitter, the Powermid doesn't receive it. As advised, i have stuck the emitter on the lower left hand corner of the Powermid. This is definitely where the input is, as I've tested by covering different parts of the Powermid with my hand.

Any input is much appreciated - this is a really important project for my quadriplegic aunt. Needless to say I'm off to a slow start.

Thanks!
Ryan

It sure looks like positioning of the emitter. If you can send the IR code directly from the Ocelot to the TV and it works, you know the Ocelot is OK. If you can point the TV remote at the power mid and it works, you know your power mids and remote are OK.

The emitters do not have much power and can't transmit very far. It could be the distance between the front of the power mid and where the actual receiver is inside the power mid itself. I did this very thing many years ago and it worked for me.

Holding the powermid in bright sunlight might help you in seeing where the IR receiver is located.

Thanks a lot for the quick responses. I've done the light thing, and the receiver is definitely in the bottom left corner. Also tried just about every other spot available on the powermid.

If you can't think of anything else it could be, would you recommend other solutions? My goal is to send a signal from the computer downstairs to a tv upstairs.

Thanks again for the help.

If you can hardwire a connection between the two, you could make or buy a "IR blaster" and forget about the Powermids. Another possibility might be to use a blaster to send the signal to the transmitting Powermid.

Let's verify that the IR frequencies are correct. In C-Max, click Controller Utilities, debug timers and variables. Scroll down until variable 60 is shown. Point your remote to the Ocelot IR receiver and press the button for IR #1. Does variable 60 report a 1?

If it does, then the frequencies that the ir commands learned are correct. If not, you may need to check and see what frequency the IR commands should be for your TV.

Kevin, the Ocelot's Ir receiver demodulates the signal and only learns the signal envelope. This is why we need to "tell" C-Max what frequency we want it to play back the signal at. This test would only tell us that the signal envelope was learned correctly (still a good test).

But you're on to something: what if the IR frequency that was specified when learning isn't the right one for that TV? If Ryan could tell us the brand of the TV (and the model, or year it was bought in) and what frequency he sapecified when learning the IR codes, we might be able to look it up and see if that might be the problem.

I would be very surprised if this was an frequency issue. I just successfully sent a signal from the Ocelot to the TV via emitter, then put that same emitter on the powermid, and it didn't work.

My test TV is an old Zenith, and I'm going to need this to work on a Uverse receiver.

By the way, I haven't yet learned how to progran C-max, as I've just been doing this through HAL.

This is really strange. You've proved that every component is able to work, but somehow the emitter and the Powermid won't work together. All I can think of right now would be to try a different emitter, or an amplified emitter to drive the Powermid.

Also, doesn't the Powermid have a direct input jack? I don't have Powermids but seems I remember something about it having a jack somewhere.

The Powermid "receiver" unit has an output jack that you can plug an emitter to send the signal to the IR receiver on the TV. The Powermid "transmitter" unit has no such jack to connect a mono cable from the ocelot (at least not my model). I was suggested that by the HAL vendor too.

I agree with your different/amplified emitter suggestion. I'll look into that.

Thanks!

Think I'm gonna buy this Blast IR Emitter and put it next to the powermid. Wish me luck!
