vda,
If you're interested in using a remote as a general microcontroller then I recall I posted the src for an entire operating system for the JP1.2 remotes (e.g. the URC7555). The OS completely wiped the chip (of course), but then it leaves you in control as to how you make you remote work - or to ...

I've got a USB multilink pod and I've used it to look at the MCU Flash. Sure enough it says it is protected. (BTW the 6 pin on the pod is NOT the same as JP1.2 I had to make a 'jumper' cable to arrange the pins right)

I've been performing measurements on the remote prior to erasing it's memory and ...

Thanks aberguerand.

I bought a 7555 and indeed it has JP1.2. I couldn't see any id on the 'chip' but the resonator and pin 5 of JP1.2 are connected to the same relative positions as per Mike E's schematic so I assume that it's the same chip.

BTW, The 7555 takes 4xAAA batteries (6Volts) whereas ...

Anyone have a list of HCS08 remotes? I'd like to play with one but I looked here in the UK and the 8820 didn't seem to be available. The 7555 7740 3440 all seem new but I didn't want to buy one just to see if it was JP1.2. None of them are 'slim' like the 8820.

Well it appears that you can only program ONE event into this little marvel. My English manual didn’t make that clear but the RS manual says it clearly "before you program another event you must clear the existing one".

I'm speechless. I paid 20 pounds for this gizmo. That's 36 US bucks (as opposed ...

John,
Thanks for pointing this out. I naively thought that once I had a JP1 Interface I could program the beast.

It appears that the memory is used for storing date and times of recordings and not for device setup except for a few bytes at the top (the 10 20 in bytes 12/13 are the device code 0032 ...

Hi,
I've got the JP1 interface to the 5220 working. I'll post some pics if anyone else wants to do this.

I'm not sure what to do next. I've downloaded the data from the eeprom and its here:

IR.exe says something like 'can't find ...

Rob,
You're right. Apart from the logo :) it looks identical to the 15-1996.

I couldn't find any info here on the 15-1996 either, but I've opened it up and I think I can see where to connect the wires for JP1. As far as I can tell it uses a 24WC01J eeprom and the S3C8 processor. There's not a lot ...

Upgrading a URC-5220 VCR programmer

Hi,
I've just bought a URC-5220 VCR Programmer. I hoped it would be JP1 compatible but it doesn't have the header and the PCB tracks I can see are 8 'staggered' pins. Anyone know anything about this device?

Since I searched the site for 5220 and found nothing I thought you might like some more info ...

He guys, Thanks for all the help.

Robman - thanks for the offer but by the 'lack of codes' I meant I didn't need them all rather than some were missing!

And yes, the DVD input select does use that rather strange RC6 code, but I got it to work on the Marantz SR-7200.txt combiner using OBC 010 and ...

Jim,
Thanks for the help. I tried your combiner but it didn't work for me :( , however there was another for a 7200 and that had enough in it for me to extract some codes. I haven't got a full set, but enough for my needs.

Thanks again!

Marantz RC5200SR protocol?

Hi,
I'm new to all this and thanks to your help - I've even got an extender working on my OFA URC7562.

Now I'm trying to program for my Marantz amp/tuner SR4200. I think this may be the same as the SR5200, certainly the remote is numbered RC5200SR and other Marantz amps I've found on the web seem ...

Send IR codes from Device Keys

Hi, I'm new to all this (in fact after speaking unsuccessfully to UEI I was searching the web for a more programmable remote when I discovered JP1) Since then I’ve made a cable and successfully programmed my Eiki projector (thanks guys) and now I’m getting ambitious :)

Here’s my question: UEI say ...
