JP1 Remotes

I have been trying to use Device Combiner to produce a long duration power-on command. I have discovered that when I enter the Protocol Id for my Panasonic TV using Panasonic MIX Combo with Device = 128 and Sub-device = 0 giving a Protocol Id: 00 1F and Fixed Data:BF FB FE FF FF FF FF FF , keymap-master rejects it as invalid when I enter the values into Device Combiner. I used an alternative Protocol Id: 00 C9 - which it accepts then changed it back in IR. The remote functions fine and I know this is a valid protocol value so the keymap-master validation must be wrong - or maybe I am

Any thoughts?

Regards, Nick.

You're wrong...

As per the readme:

Any protocols specified in the Device Combiner MUST use 1-byte function commands.

The Panasonic MIX Combo is a 2-byte protocol that CANNOT be used with the DC. Since it essentially uses the standard Panasonic signals, the regular 00C9 protocol will work with the DC.

Mark,

Thanks for pointing out my oversight!

So, if Device Combiner doesn't support 2-byte protocols, yet my remote seems happy with 2-byte protocol and function code with the duration modifier, isn't there a mismatch between Device Combiner and remote which, if resolved, could open up greater capability?

The 00C9 protocol won't work with my TV.

I'm not sure what you're getting at, so you might want to try re-phrasing the question. Your remote will not only handle 2-byte protocols with no problem, it will handle protocols with more than 2 bytes. The issue here is that the Device Combiner was specifically written to handle 1-byte protocols. All protocols combined using the d/c need to have the same number of variable bytes, so setting it to handle 1-byte protocols made the most sense. If it were re-written to handle 2 byte protocols (which is possible) then all the protocols combined using it would need to be 2-byte protocols.

Most 2-byte protocols are combo protocols, as is the case with the Panasonic MIX Combo, so to include these signals in the d/c you will need to break down your upgrade into it's component parts using the regular "C9" Panasonic protocol.
