JP1 Remotes

Found this forum a couple of days ago - lot's of good info but still over my head right now.

I want to ask two dumb questions.

1. I have a remote for a motorola digital cable box which turns out to have a jp1 connector. It controls my tv, the cable box and has a third button for vcr. Can I get it to control the volume on my ht system?

2. I have an 8910. Can I get the device keys to change the source on my ht system without using an extender?

Thanks for the help.

Steve

My ht system is a jvc th-m45. I've not found this specific system in the lists but I found it works the rudimentary controls if I set the recv/amp to 0074.

The cable box remote has two stickers in the battery compartment. G00702 and 3MBxxxxW00.

Your cable box remote wouldn't happen to look like the one on the far left here: http://www.urcsupport.com ? If so, there's no RDF for it (yet) and a starter rdf will need to be made. You can get help here for that. I suspect from the sticker it's a Millenium 3. Use IR and download the eeprom and post it in "diagnosis" and someone will at least decipher the signature.

Wow. You're right. It is the one on the far left. I've ordered a jp1 cable and will be able to post the eeprom download soon.

Steve,

I just tried it again twice, once in a new browser to make sure it wasn't just "cached" and both times it worked. In the last five minutes, The site hasn't "been down" that I could see. Obviously n2deep was also able to get there. If you still can't, try adding a "/) at the end of the url.
FWIW, the Mill4 stickers (if any) will use "4MxxxByy" designation so it really wasn't too hard to make a quick guess. With one less device, it'd be interesting to see how they setup the eeprom for this one. Just a stab in the dark, the signature may be something like "Milxmilx", but we'll see when he posts an IR dump. I'm guessing with a little button pushing, a full-fledged RDF could be made in a short time. Gee, Nils, aren't you excited?

BTW, there's a decent chance this will support a "hidden" fourth device. n2deep: are you comfy with taking it apart and either reporting or posting a pix of both sides of the pcb? Nils may also need a decent pix of the remote with the cover slid down or removed to do the image map for RM support. I'd suggest with cover removed.

Sure. I'll take it apart tonight and post the pics.

n2deep,

I saw the pix at urcsupport. and the key layout on the bottom half is much different than used with the Mill4's. When you post the pix, make sure the S0x numbers are good and readable, even if it takes 2 pix to make sure. Whatever is printed on the PCB opposite side will also be important, especially anything giving clues as to it's version number. Are you sure that the sticker said W00 rather than B00? sometimes these stickers can get wore out or torn from batteries.

Also, did you happen to get a manual with the remote? According to the ueic site, there's very few features/restrictions, butit's common for the online manual to be really crappy about such details. With a list of 9xx commands in a printed manual, we'd have a head start for advising about making the rdf. I did see 990, 991, and 993 (VPT) mentioned, but nothing about 994 (keymoves), 995 (macros), 996 (channel lock to cable device), or 997 (cable lock).

I have two of the remotes (two cable boxes). They definitely are W00 and not B00 (stickers have no wear). I'll get as much detail in the pix as possible. Thanks for the tips. I'll know where to focus...

Unfortunately, the cable company (time warner) did not give me any manuals. In the past when I changed my tv, I had to call their support folks to give me the code!

I used the setup code 0074 on a my new 8910 remote under the receiver/amp device. When I use 0074 on the cable remote under the vcr device it doesn't drive my ht system at all. Is this because my cable remote doesn't understand 0074 or is it because 0074 isn't a vcr device code (please don't confuse me with someone who knows what they're doing here!!)

Thanks, Steve

Pix can be found at http://www.villagephotos.com/pubbrowse.asp?selected=671591

The only chip on it has the following on top

ATMEL002
24C08N
SC18

Let me know if you cannot make out any of the details in the pictures. I've posted one top view and one bottom view of the pcb.

Thanks for your help,
Steve

Steve,

Your Mill3 is a three device remote, with Cable/Sat, TV and VCR devices. It likely doesn't have any audio codes installed, or at least for now can't access them. VCR 0074 and Audio 0074 are two different things, like apples and orages, both fruits, but not near the same.

There's a decent chance that it *may* support a hidden fourth device, and it *may* be audio. For now, without IR support, and the RDF, we won't know, nor is there a way to access that device manually(button pushing).

I've started an rdf for it, but still need the pix of the PCB. Then when you get your cable you'll need to use IR and some button pushing to build the rest. Shoot me a PM if you'd like help with that part.

Jim
