JP1 Remotes

I have a 6131, and have built two upgrades for it. One of them is to control my Marantz receiver, and works fine by itself. The other is to use the Marantz receiver to play the music from my computer through my TiVo, and works fine by itself. The odd thing here is that when I add these two upgrades together, the first one that is added does not work correctly. Whichever one I add second works fine. It is as if one is trumping the other, but I can't see where or why. Could someone please take a look and see if anything becomes apperant to you? I have posted the IR file here. Thank you.

For starters, there's 2 copies of the Device Combiner protocol ($0144) on the Protocols tab. They appear to be identical; one should be deleted.

Are both upgrades accounted for in the DC protocol (proper PID and Fixed Data, etc)? It would be nice to see the upgrade files as well to make sure everything is ok.

Mark,
Can I only have one Device Combiner? I thought that I could have more than one. I have one for the receiver, because it is a combination of rc5 and rc5x. That is on the Audio device. I have one to control the TiVo Home Media option, through the receiver, which uses the PVR controls and menus, but uses the receiver to control volume. Because I must use a different input selection on the receiver for this, I made the DC. This is on the Cable button. I put the TiVo HM Option DC here and the Marantz combiner here. I think they are correct.
Jim

Since there can only be one copy of the DC protocol installed, what you do is create a "master" where you add all the protocols you want to combine. Even if the device upgrade in the file is for a subset of the devices, the DC must contain everything you want to combine.

Then you create additional upgrade files (seperately), but use the PID ID# from the master in the byte2 column.

For example, a DC upgrade for a TV and Cable is created. The DC table contains the PID/Fixed Data for each one (TV=0, Cable=1).

Now let's say you want to add a VCR and RCVR. In the first file, you add the PID/Fixed Data for the 2 new devices. This becomes the "master" protocol, and needs to get pasted into IR. Then you create the new VCR/RCVR upgrade using the proper PID #'s (2 and 3) in the byte2 column. When you're done, only copy the Device Upgrade code over to IR... the DC protocol code is there from the first file.

What I have done in these situations is created an upgrade file where I only maintain the DC protocol settings... the upgrade doesn't matter and isn't used. Then I've created 2 or more device upgrades to combine the various equipment.

As long as you use the proper DC ID# for the byte2 setting, everything works.

I hope this helps.

It's also important to remember that as the remote search for upgrades (device or protocol), it will use the FIRST one it finds in EEPROM. Therefore, subsequent upgrades with the same setup code or PID never get found.
