JP1 Remotes

Hi,

I have a OneForAll URC-7930 and have been able to find setup codes for my TV (no problem) and my PVR (some key magic required).

However, I cannot find a code for my Amp/Receiver - an Onkyo HTX-22HD. All I need is the following six buttons: volume +/- (for punch through), input +/-, listening mode +/-

I can find codes for the URC-7940/7950 on the OFA website: 1320, 1531, 0135 but these do not work with my 7930. These setup codes are listed in the JP1 Lookup Tool as _pid: $017E, _pid: $017E, NEC1 respectively. No alts are listed, and I do not understand the other information in the lookup tool, sorry. Embarassed

So, my question: is there a setup code for my Onkyo HTX-22HD that will work on my 3-in-1 remote that has TV/DVD/VCR buttons on it?

I'm hoping that I can make do with this remote but my gut feeling is that it's limited capabilities might leave me unable to control my devices.

Any help appreciated. Smile

Thanks,
matt

I found the user manual for the Onkyo HTX-22HD here and the user manual for the URC-7930 here.

Looking at the user manual for the remote, I can see that it doesn't have an AUDIO device button, it just has TV, DVD and VCR, so therefore you won't be able to control your audio device with this remote.

If the remote has a 6-pin connector in the battery compartment, it's possible that it can be re-programmed to control audio devices using JP1, but as we haven't seen this remote before we would need to do some setup first.

Hi Rob,

I thought as much. OFA have not responded but I assume their answer will be the same as yours...

It has place for 6 pins on the board, but there are no pins or connector so I'd have to add those in. I've still got a JP1 cable from a URC-7562 I programmed many years ago if that can be used?

Wondering if it's worth the hassle when I could just buy a version of this remote that has an AUD key? If that happens, I would be happy to send this remote to somebody in the UK who would be willing to take it apart for the research purposes and benefit of the site.

Though I did read that the 4 and 5 device models have a bug where they forget what device mode they are in, which is why they are much more difficult to buy (OFA no longer list the 7940 and 7950 on their site).

The remote I have is actually a piano black version, model number URC-7931

Cheers,
matt

Are there holes in the PCB ready for a 6-pin? If so, it might be that you only need to add the pins, nothing else, though we won't know for sure without seeing pics of the PCB.

Your old URC-7562 is what we call a "JP1 (EEPROM)" remote whereas your URC-7931 is almost certainly a "JP1 (Flash)" remote, so you would need a new JP1 cable to program this remote.

Only you can decide whether it's worth it to you to mess around with this remote. If you decide to get a JP1.2/3 flash cable anyway, then it probably is worth soldering in some pins to program the remote.

There are no holes for the pins.

If I can figure out how to open the remote I'll take a photo of the PCB.

I've ordered a new remote but will not rule out messing around with this one.

If there's no holes, adding a 6-pin could be quite tricky because you would need to figure out where each of the pins needs to be connected.

In that case I'm glad I've got a replacement on the way. Smile

My offer of donating the remote still stands.

see this thread before attempting to modify the remote:

Wow, Edmund.

That was some great reading - but I have to say the whole thing is too much for me. Thanks for saving me some time. Smile
