JP1 Remotes

[jetstar52]

I've uploaded the IRScope file for the four "Scene" buttons from my Yamaha HTR-5063 remote. They appear to use the same protocol that Rob and Vicky deciphered for the "Gap helper" upgrade. I would like help figuring out what the OBCs or EFCs would be for these four signals. Thanks!

Yamaha has started using a variation of the Nec1 protocol to get some things like inputs to work. Yamaha calls these "custom codes".

These signals are decoding as Gap signals.

So in case you missed the bold chars in Vicky's post, here are the OBCs:

Scene 1 = 0
Scene 2 = 3
Scene 3 = 6
Scene 4 = 9

P.S. Jetstar52, I really had to dig through a long list of rambling posts (where I was just learning how to do protocol upgrades) to find this information. I used your post to for a place to quickly find the information. Thanks for giving this post such a nice title.

Thank you so much! I tried out the codes today and all are working. You are geniuses. In fact, had there been remotes in old Alfred Nobel's day, you'd be making annual trips to Oslo.

Is it possible to use this "gap protocol" along with the NEC1 protocol in Device Combiner, or must I use two separate upgrades and keymoves?

[jetstar52]

OK, I found another gap protocol, this one is 127.1 rather than 122.133. Plugging those values into the Gap Helper protocol yields nothing.

When I created my upgrade, it sent those same signals as expected.

[jetstar52]

It works. I had everything right except the OBCs. It remains a mystery to me where to find them in the IRScope data. Thank you again for your help.

Will device combiner protocol be able to use this gap protocol?

What are you trying to combine? Do all these different functions come from the same original remote? Rather than trying to mess with the Device Combiner, we'll probably need to make a custom protocol that mixes different device codes with the gap protocol and regular NEC signals.

You know a long time ago 3FG said this about our Yamaha Gap

Vicky,
The passage you quoted above wasn't really correct, and for sure it doesn't apply to the "gap" protocol. The issue I was grappling with, and misunderstanding, is that RM uses a different behavior for NEC1 (005A) and NEC 4 Dev Combo (011A) executors. This relates entirely to the second byte of the device data, and whether the executor should use the fixed data value for the subdevice or compute the complement of the device number. I still think that the behavior of RM is wrong, but that's a different discussion.

The issue we're seeing now revolves around function numbers, and the traditional rule that the second byte be the complement of the first. It is analogous to what happened a long time ago with device numbers, which at one time followed a strict complement rule for the two bytes.

Yamaha is now sometimes breaking the complement rule for function numbers. The signals you have decoded all add to 127 instead of 255, but inspecting the Yamaha IR code sheets shows that Yamaha also sends IR signals that don't add to either 255 or 127. So, in general, it appears that Yamaha may use 2 bytes of independent information for the function data.

The 011A executor allows one to specify 3 bytes of independent data and one dependent byte within one IR signal: device, sub device, function number, and comp of function number. The fourth byte is the complement of the third.

For the Yamaha signals, as documented, there are also 3 bytes of independent data, but the second byte is the dependent byte (complement of the device number).

Our executors normally accept one or two bytes of input data. The 011A executor uses one byte to specify the function number, and the other byte is a control byte that chooses the device number from fixed data, sub device either from the fixed data or by complement, and also selects the NEC variant type (NEC1, NEC2, etc). I don't remember what the other two bits are used for, if anything.

If we write an executor specifically for Yamaha, it could take one byte of function number, and a control byte which selects device number and function total (255, 127, and some others). The executor would then always compute the complement of the device number, and would always send NEC1 style signals.

It's one way.....

[vickyg2003]

I didn't understand it the first time around, but I do now. I went back to the original post and looked at what your EFC's were doing in that original post. Apparently the Yamaha needs 3 or Devices with no subdevice and then for the discretes there are a bunch of device/subdevice buttons. Do these receivers control the things plugged into them? Is that why it is so complex?

Yep, combining everything into one upgrade would be great.
