Hi,

What does the IR frequency setting do in the Ocelot CMAX software? It is in the dialog box that you use to 'learn IR'.

I couldn't find any reference to it in the manual.

Thanks!

The Ocelot IR receiver can accept IR signals from about 28 - 60 KHz. The Ocelot cannot determine the incoming frequency.
The default output frequency is 38 KHz. If your A/V equipment expects a different frequency, you can enter it in this screen.
The saved IR signal will be transmitted with the carrier frequency specified during the save process.
If you are having problems controlling your equipment at 38KHz, try bumping the frequency up to 44, then 50, then 57.

Dan,

I am really struggling with this... I can't seem to get consistent results with the Ocelot recognizing IR. Currently I am not trying to send IR from the Ocelot. I did try some different frequencies, but it didn't seem to help.

Basically I am using a pronto to send the IR. I picked philips VCR default codes as a dummy device to send commands to the Ocelot (the Ocelot will issues X10 in response).

In the Proto it would be something like [C] UDB Philips, Philips 1, VCR, Menu Down, RC5, system 0, command 0.

When I issue the IR 50% of the time ocelot will do the right thing, but the other times it will not match the IR OR will match it to a different IR command. (I have version 1.07j firmware). I have stored about 10 IR codes.

What is a good set of codes to use?
What frequency should I use? I can use anything the pronto has built in since I am mapping to X10 control.
How can a optimally record IR in the Ocelot?
When recording IR do I hold the remote button down until learned or just tap it?

Thanks,
Jeff

Dan:

This is interesting news. I had thought the Ocelot sensed the frequency. Now I am wondering about something.

If the frequency is not set right, will the device work at all, or just part of the time.

I have a problem with my front projector not responding all of the time, only about 75% of the time. Is this possibly a frequency thing?

Is there any way to determine frequency other than trial and error?

I'm running Marantz, Velodyne, Fujitsu (projector), HunterDouglas (Blinds), and Toshiba all on 38 kHz. Does this sound plausable?

Thanks for the great support you guys provide.

Look here to find out how to determine frequency:

I had a similar problem setting up my Ocelot, I used Yamaha "dummy" codes and could only get good results about 40% of the time and from only about one foot from the sensor. When I changed to Curtis Mathes (0300) I got 100% at over 10ft. (that's as far is I could go.)

Have you been here yet?

Hope this helps.

I have had no problems at all using Sony codes. I also use Yamaha codes, and there is only 1 code out of about 20 that the ocelot doesnt seem to recognise.

Thanks to Paul's links, I was able to set the formula for determining the frequency into an Excel spread sheet. Now all I have to do is place the second 4 digits in the Pronto IR code readout in the spreadsheet and it gives me the frequency.

I had been using the default 38kHz for everything, but found my projector operated at 38.739 kHz, so I changed the Ocelot to 39 Khz to be closer. We'll see what happens.

Several other remotes operated off of the 38 kHz default by a little bit, such as my Marantz receiver using 36 kHz and my HunterDouglas PowerRise shades using 42 kHz.

Deane

Could you post your spread sheet?

I will if someone will tell me how to do it. I'm a posting dummy.

Deane,
Would you email me a copy?
