Russound video distribution system

I am new at JP1 but have figured out a lot in the last 5 days. This forum has been a great help!

I want to create an upgrade file for my russound keypads (video distribution system to 4 rooms) so I can load it in several 6131 remotes (JP1 modified). I used an 8910 remote to learn the necessary ir codes and it works perfectly. I cannot figure out to create an upgrade file as it does not appear the codes are being decoded properly.

The Russound remote that I used to teach the 8910 the codes is a rebadged Theater Master SL9000 that uses code 0081 for the russound device

The IR file with the learned codes I need to use for an upgrade file is in the diagnosis area.

I see some similarity between those signals and the signals I understand from other Russound models, but it doesn't seem to be the same protocol.

This one will take a bit of study in order to figure out how to build a protocol executor. I'm not sure when I might have time.

If you're in a hurry you'll need help from some other expert.

Meanwhile, do I understand you correctly that you tested the learned signal on the 8910 and they correctly operate the Russound device?

Thank you for your quick response! I was afraid a new protocol was neccesary. I even found several ccf files at remote central that I tried to decode with no luck.

I have tested the learned codes and they do work. I even deleted them several times and relearned them to see if I could get any more info. Looks like I will just have to wait until someone cracks the protocol.

Try this upgrade...

Upgrade Code 0 = 8F D0 (Video Acc/2000) Russound Keypad (KM v8.31)
FF 00 C1 00 A2 A4 A6 A8 AA AC 8A B4 00 98 9A 00
End

Upgrade protocol 0 = 01 FF (S3C8+) Russound Keypad (PB v3.11)
44 8C 01 8B 12 84 05 08 07 03 84 00 00 00 00 03
70 26 66 0A BE 05 64 8D 01 46
End

If it works, I'll upload the upgrade file so you can customize it. I've put all the functions on the same buttons that you learned them to.

Wow! what a great response!!!!! It works perfectly.

I will look for the upgrade so I can modify it for my 6131s

Just to make sure.

You did delete the learned signals before testing the upgrade, right?

If you used the same device key to assign the device upgrade, the learned signals would take priority over the device upgrade.

Yes
I deleted the learned keys and then installed the upgrade. Then tested and it works!

Here's your upgrade file. The zip contains both the KM file and the PB file that I used to generate the protocol.

In case you're curious, here's how I did it. First, make a note of the carrier frequency, which is 37.735 khz. If you look at the learned timings that you posted, they all look something like this...

+5484 -2798 +1828 -1792 +1828 -5414 +1828 -19628
+5484 -2798 +1828 -1792 +3630 -1802 +1828 -21438

When you work with these numbers you can round them up to make them cleaner.

The +5500 -2800 pair at the beginning is the "lead in" pair.

At first glance, these look like bi-phase signals, where one pair would be "+1800 -1800" and the other pair "-1800 +1800". You would expect to see the +3600 time where two -1800 follow each other, but the -5400 kills that theory.

So, if you edit all of the 3600 and 5400 times into 2 and 3 pairs of 1800, you have the beginnings of the binary. This signal is a little unusual in that each "pair" is just one time, where...

1 = +1800 -0
0 = +0 -1800

(btw, + means "on" and - means "off).

The leadout time is 19660. The reason that some of the lead out times appear longer in your learned signals is because there are some -1800 ZERO times included in them.

Many thanks Rob!!! I have only been at this since Thursday. I would not have know where to start to decode the signal protocol. I wish I had found this forum years ago as I have never been able to program any one remote before to handle everything I have in my system. What a relief to be able to program the remote and not have to enter keystoke by keystroke into the remote!!!!

If you think doing this stuff is your thing, check out the Protocol Builder spreadsheet, that's what I used to create that executor for you. Here's the help file that tells youhow to use it.
