JP1 Remotes

There are only 256 possible OBC1 values (ie, 0-255) for each OBC2 value. The fact that you found one button with a different OBC2 value certainly opens the door to the possibility that there are others to be found. It appears that you went as far as OBC1 119 using OBC2 0, so you could still test ...

SUCCESS! After years of searching I finally found an ir code for the AppleTV HOME/TV cmd. It is included with this Device Upgrade I have posted in Media Players with the other Apple TV upgrades.

Another concept which is useful when you're trying to cram too many devices into one remote is, some devices aren't devices that you really use directly, they're more like device that help you use other devices, like a/v selectors for example, so for devices like that it's usually best not to waste ...

Multiplex has the same effect as holding the setup button and manually entering a new setup code. So you're correct that you need multiplexers to change to different setup codes and to change back to the original.

I use a mulitplexer like yours where I multiplex 9 devices on the same device button ...

Hi All:

I am new to using extenders and have a question on theory of operation. I am using Comcast JP1.3 remote that has 4 built-in devices and trying to control 6 devices using the multiplexor function.. [I realize there are other JP1.3 remotes with more devices, but I prefer the Comcast remote as ...

Just an update on this from my side. I still have no luck with the JP1.3 Common Extender, however, I thought I would try the older Comcast specific JP1.3, version 1.02, here:

The Comcast specific extender loaded just fine for ...

Hi,

I was excited to hear about this extender for the Comcast 30393039 remote.

Unfortunately, I had trouble with the extender after I installed it and could use some help.

What worked:
1) Merge install using RMIR v2.09build8 on Ubuntu 18.04
2) Uploads to the remote
3) Extender appears to activate ...

It looks like you're looking at the RMDU file using Notepad, you really should be viewing it using RMIR as it will give you much more information.

From what you've posted, that RMDU file is using the regular NEC1 protocol with device code 122. The fact that there's no sub-device means that the sub ...

Post your RMIR file so we can see how the newer upgrade went south when you added it to your remote.

Hi mdavej,

Thanks for offer for the help with the RMIR. As I was cleaning my RMIR, I inadvertently solved my problem.

For the benefit of others, I had replaced the old device Yamaha HTR-54x0 ...

After reviewing my old devices and comparing old files I found something strange.

It seems I was using an old Yamaha HTR-54x0 file to control RX-V620.

The keys defined for the HTR-54x0 also seem to work on my RX-V685.

Hi Rob,

Thanks for the quick response and the pointers on NEC1 vs NEC1-f16 protocols. I thought I was using the zones correctly, but I will double check the Yamaha manual. I appreciate the confirmation that the Comcast JP1.3 will support the NEC1-f16 protocol as that will save me some time ...

I have also uploaded ... the ALL , Main and Zone 2

Hi rsbrux and all:

I was very pleased to find this thread now that I had to replace my old RX-V620 with the RX-V685. I tried to use the files that rxbrux posted to update my old Comcast JP1.3 (30393039) remote with codes for the new RX-V685 ...

The DIY Gadget flash cable does not work with JP2 remotes. It is able to write to JP2 remotes, but not read from them. We don't know why. The latter pages of this thread lists several cheap ways to get a FTDI USB to RS232 adapter, and of course it is available from Mouser too.

Thanks for quick reponse vickyg2003! I just installed RM this morning. When I check the about box, it says I am running "RemoteMaster v2.02a". If I check for updates, I get a report that I am using version "v.2.02a Beta 1.5w"

I must admit I am bit confused by the numbering convention. I assume the ...
