JP1 Remotes

My Volvo Nav system has a remote, and I learned the signals, but the DecodeIR isn't helping me too much. Can anyone make heads or tails of the below code?

(Reason being is that my radio is also IR-controlled, and I'd like a starting point to code search, since I don't have the remote for it)

Thanks!

The readme file for DecodeIR tells you that ID-000D is called "Akai" in devices4. Since I wrote that this protocol has been renamed to "Akai" in a few other places. I think it's Akai in KM and RM. I'll try to remember to change it in DecodeIR.

Meanwhile, see what you can get with an "Akai" upgrade in KM or RM.

Thanks for the information. I got some more information, however, that leads me to believe that the Nav and the radio use different protocols. The remote (I found out from someone with it) has "Mitsubishi" stamped all over it, so I assume that it uses a Mitsu code.

I'm going to try the 8 Mitsu codes and see if I have any luck.

I suppose it's possible they are using a protocol that doesn't appear in devices.xls, or is that a "remote" possibility?

Thanks John,

I have a bit of experience with that code. The name Mitsubishi is all over it as the chip in the OEM remote (and possibly the receiver) is Mitsuibishi.
(I was using the receiver/decoder chip in a project, and had to figure out the protocol to I could make and upgrade that did what I want)

I'd consider making an upgrade rather than do a code search, it isn't that hard.

Not sure what you mean here - I made an IR file having each of the distinct device/protocol combos (there were 4, I think) and was going to code search each to try and find what made the head unit do something.

I'm not sure if both the Nav and the Radio are Mitsu - they may very well be two completely different things!

I believe current Volvo NAV systems are Windows CE based and OEM'ed from Navtec (www.navteq.com). I know that Navtec makes the application and data but I don't know who makes the hardware. I've go an S60 with HU803 H/U (this H/U is made my Mits.) and no remote I've got a XC90 with NAV on the way and I've played with JP1 a bit some I might be able to help.
Maybe you can find some leads here, or maybe we can find some volvo owners to bring over to JP1 to join the hunt: http://forums.swedespeed.com/
I don't know if this will help solve the remote issue but this link might be useful http://apps.volvocars.us/ownersdocs/200 ... c90_10.htm

You are correct - CE-based, Navtec system. The HU-803 evidently is a Mitsu unit from what I'm told. I am going to have a go at a code search tomorrow, and someone at SS has offered to send me his remote for analysis.

Through one of these channels I should be able to get the code(s) sorted out.

I'll report back with what I find!

I found this very frustrating!

I tried all number of Mitsu devices, and Akai devices, with no luck. In fact, I even tried making a device for the learned Nav signals with no luck. In KM I used the Akai protocol, the dev1 of 4 as indicated in DecodeIR, but no dice when I tried to operate the Nav...

Any ideas?

Make some fake upgrades, playing with the device codes, and some EFCs to make the upgrade, and try the rest of the EFC manually (that is how I figured out the protocol, to my purpose).

I think John Fine's decoder correctly considers this protocol to have a three bit device number and a seven bit function (OBC).

The Protocol 000D considers it to have a two bit device and eight bit function or OBC.

In you upgrade change to device=0 and use OBC's (not EFC's):
OBC
43 up
49 down
45 left
47 right
39 enter
53 center/exit

The decoder showed the OBCs in the 20s in IR - where did these #s come from? Also, some of the learned codes showed an additional piece of command when learned -- consistently. Is this important?

Here is the progression:

The first two columns are device and OBC in decimal. The third and fourth are in binary split 3 device and 7 OBC bits the way the decoder thinks of them. The fifth and sixth are the way they are actually sent and stored in the remote which, in this case, are backwards. The seventh and eighth are the way UEI thinks they are split 2 device and 8 OBC bits. The ninth and tenth columns are the bits reversed and the 11th is the OBC in decimal (the device is 0).

And to answer the last question: no, the extraneous information can be ignored when you get good consistent decoding (device number the same and OBC's in sequence)

I guess I'm confused as to where you obtained this information from. My version of KM doesn't reveal anything besides Device/SubDev/OBC/Hex/EFC. ...and why is IR calculating the wrong OBC?

That's just it, though - the "extraneous" information is consistently learned -- as though it is part of the signal. Why is it there at all if it's not important?

The readme from DecodeIR.dll says ...

ID-000D: {38k,289}<1,-2.6|1,-6.3>(D:3,F:7,1,^25.3m)+
UEI protocol 000D
"Akai" in devices4.xls
Used in all the Harman/Kardon devices I've seen that aren't NEC. Also in some
JVC, Makita and maybe Mitsubishi.

The expression "D:3,F:7" means device expressed in 3-bits and function (aka OBC) in 7-bits.

...and why is IR calculating the wrong OBC?

IR calls DecodeIR.dll and according to it's definition it is decoding it correctly.

I originally decoded PID 000D manually using an OFA remote and you can easily detect the byte barriers by making the fixed data FF and the variable data 00. UEI's protocol assumed D:2,F:8. Frankly, we all do this by reverse engineering and we are guessing at the byte barriers.

I think the actual raw signal is consistent, DecodeIR will offer multiple interpretations.

Neil, I think you're making this harder for yourself than it needs to be. Rather than trying to understand how Jon came up with the numbers that he did and why IR displays the extra Async decodes, just try entering the code numbers that Jon posted into KM and see if it works. If it does, who cares why it works just that it does.

Here's an upgrade that contains the 5 buttons you posted...

Upgrade Code 0 = 07 D0 (Cable/2000) keymap-master Device Upgrade (KM v8.31)
0D 00 08 00 7C 09 00 E4 D4 8C B4 F4 E4 AC
End

I notice that the leadout time on the learned signals that were posted is significantly shorter than the $000D leadout time, so if the signals don't work, this could be why. In which case I will create a new protocol for you to use where the bit boundaries are set correctly.
