Help: Trouble with Scientific Atlanta Explorer Cable Box

[nsuri]

Hi All,

I am having trouble with controlling a Scientific Atlanta Explorer 2100 Cable TV box using UIRT2 and Girder.

I have tried learning (both in standard as well as raw modes). I have also tried codes from Pronto ccf files (from www.remotecentral.com) and no luck with that either.

Other devices seem to work fine, so I know I have a functional UIRT2 and a good install of Girder and the UIRT plugin.

Here is the sequence when I try to learn the power button:

02D22D423F2F0F11002000AAA22A0000000000000000000000

In Raw mode, the sequence is:

R02D2423F112F112F110F113011301130112F112F110F110F1 10F110E110F1130110F110F110F110F110F1130112F112F11

I also tried the IR Debug option and this is the output produced:

I also tried the different frequencies in the dialog but no luck.

Has anyone else successfully used UIRT2 with this device? Am I doing anything wrong?

Thanks for any help!

The Scientific Atlanta cable boxes use 57.6 kHz carrier frequency. I think you are hosed.

David

That was what I gathered as well. The remote for the 2100 doesn't make my indicator LED on the USB-UIRT blink. :(

Guess I screwed myself by not ordering with the 56K receiver option for $5 more :cry:

You can still transmit 56khz signals with the USB-UIRT even if you don't have the 56khz option. You just can't learn them. Try this code for the POWER button I generated:

0D6E2E4141103110008A2A2008A00200000000000000000000

Let me know if it works and I can post the rest.

David

[Caffiend]

I put that all in as CODE1 and my SciAtl 2100 box just sat there completely uninspired :(

I did set the carrier frequency to 56kHz too.

[judapeno]

Sorry, that was a UIRT2 code I posted. The USB-UIRT codes are slightly different. I will update my script and repost the code.

David

[Caffiend]

That would be great! I appreciate the effort. :D

[judapeno]

Okay, try this one:

184A2C6060184818008A2A2008A00200000000000000000000

Set the frequency to 58 and the repeat to 5 for starters.

David

[Caffiend]

You mean 56 right? That didn't work either :(

Thanks again!

-will

[judapeno]

Whoops, found a bug in my script. Try this one:

139A2E6060184818008A2A2008A00200000000000000000000

The information I have says this is "Old Panasonic" format, which uses 57.6 kHz carrier. So I rounded up to 58. It might not matter.

David

[Caffiend]

No better luck this time either.

[judapeno]

I feel good about this one:

139A2E6060184818008A820A080A0800000000000000000000

David

[Caffiend]

Nada. :cry:

-will

[judapeno]

Oh well, back to the drawing board.

David

[Caffiend]

Wait, can't I just import Pronto codes? I'm going to look into this. If anyone has any info on this, feel free to post :D

thanks!

Caffiend,

There will be new firmware released for the USB-UIRT in about a week which enables the wideband IR receiver inside for learning. With this you will be able to learn from your Sci-Atlanta remote even *without* the 56KHz option...

[Caffiend]

That's great news! I'll just wait it out instead of wasting a bunch of time trying to figure a work-around for my shortsightedness.

Thanks,

Hi Caffiend, Jon

Any update on the USB-UIRT and the Scientific Atlanta cable boxes? I ordered the USB-UIRT with the 56 K option, but still was not able to get it to work. This was a few months ago though, and I don't know if there have been any firmware updates.

Thanks!

[Caffiend]

With the firmware update the UIRT works great! The learning needs to be done really close (as documented with the update) but once learned the transmit has been faultless.
