JP1 Remotes

MrFSL -

The iMON VFD sensor (and it's matching iMON-Pad remote) use an IR protocol that is very different from most standard remotes.

If you have a JP1-capable remote, there are two upgrades available that will allow you to talk to the iMON sensor.

There's one from UEIC available here , and one ...

Hi Rob,

Sorry it took so long, but I finally got around to testing the version with delay. It also seems to work fine. The delay seems to do the right thing, and it's about the right length. I don't really have a good way of measuring the delay, but it feels like about the same amount of time as ...

Hi Rob,

I haven't had a chance to test the version with delay yet. Some things came up at work and I've been slammed lately. I'll try to get to it this weekend.

Hi Rob,

The latest version seems to work! All the buttons I tested (about 35) gave consistent decodes. All but one even decoded the same as the original remote. I think the "menu" function has the wrong OBC (compared to the original remote), but it does still give a consistent decode (just a ...

Hi Rob,

Sure. I'd be happy to help test any new version you come up with. I have notification turned on for this thread, so if you post here when you have a new version ready, I'll notice.

The way I'm using the Imon (in linux, with lirc), I actually only use the signals you've marked as style1 ...

Hi Rob,

Not too surprisingly, as far as I can tell, the UEI official upgrade code works perfectly.

Your revised code is pretty good. I didn't quite test all the functions (I just did the ones that auto-mapped to 7800 buttons when I switched KM to a 7800). All of the ones I tested except for Left ...

Hi Rob,

I tried the UEI official code, but it was for a 8910 remote. I tried switching it to a 7800 in RM, but I guess the protocol code didn't get switched over for the different remote. It locks up whenever I press a button...

Could you maybe port their protocol to the right format for a 7800 ...

Hi Rob,

Well, the new upgrade doesn't quite work either... Some of the buttons are pretty consistent, but others get very random lirc data. None of them seem to be quite as solid as the original remote.

The delay between the 1st and 2nd data packets is quite long -- too long for Tommy's device ...

Hi Rob,

On second thought, there were 4 on-bursts that were 90us short. That makes 360us short for the sequence, which is approaching half a bit time. That might be enough to cause inaccurate reads.

Hi Rob,

The power button upgrade didn't quite work. It does better than my best attempt, but lirc still doesn't see consistent codes (which means that the iMON receiver still isn't quite happy).

I'm not sure why it's unhappy, though. I captured the signals from both the original remote and your ...

Hi Rob,

I tried the upgrade, but I think maybe I was doing something wrong. I think the upgrade code was for a different remote, since it put the command on the rewind key instead of power... I tried changing it to the power key, but ended up with the same result.

It looks like it was trying to ...

Hi Rob,

I actually forgot about that upgrade. I plead information overload...

I'll try it tonight and let you know what happens (I'm at work now, and don't have the remote or the HTPC here).

Hi Rob,

I do have a JP1 learning remote. I've created a new dump with a few learned signals. It is here in the diagnosis area. The signals are learned to the cable device.

I think my imon remote is one of the strange protocol ones, though. IR didn't recognize the learned data...

Also, I tried to ...

Hi,

I'm trying to control a recently built HTPC, which is using a Imon IR receiver. The remote that came with the system is a IMON-Pad. It looks like there has been quite a bit of discussion about the protocol it uses (see here , here , or here ).

There are a number of files in the diagnosis area ...
