JP1 Remotes

Hi JP1r's

I need help to reprogram a Mcintosh HR056 (URC-48C20BJ0-009R).
I bought at -www.diygadget.com- a JP1 (EEPROM) USB Cable.
I did a mistake using code 981 when I was trying to make the
a Mcintosh CD-DVD player to work separately. (it has two buttons
"light CD and light DVDDVD). I did contact Mcintosh Labs and said
there's no remote codes recover data (?).

I use Windows XP Pro SP3 and have IR.exe 8.03
but XP won't recognize the JP1 cable.

Any suggestions?
TKS

I've never heard of this remote, so I can't tell you which platform it uses. How did you determine that it's an EEPROM remote, rather than a Flash remote? If you just guessed, you probably guessed wrong and that would explain why the cable isn't working.

UEI manufactured remotes are either JP1, which uses an EEPROM, or JP1.2/1.3, which use flash memory.

The required interface cables are different. But so far, we don't know if you are having trouble getting the cable to work with your computer, or if the cable isn't able to interface to the remote.

Cable /computer: with the cable plugged into a USB port, click on Start, right click on My Computer, select Properties, then Hardware, then Device Manager. The DIY cable uses a chip made by Delcom, and it should be listed under Universal Serial Bus controllers (I don't remember the exact wording). Properties/Details should show something similar to VID_0FC5&PID_1222. If you can find this, and there aren't yellow icons associated with it, then the OS is seeing the interface cable.

Make sure in IR.exe that you are trying to access a JP1 USB interface, and not a serial or parallel or USB serial interface. (I'm not at a computer where I can see IR, so I don't remember the exact terminology used.)

Are you sure that you have pin 1 of the interface cable connected to pin 1 of the 6 pin header?

If none of this works, perhaps you really have a JP1.2/1.3 remote.
Try using the 983 command to blink back a signature. It's a long shot but maybe we'll recognize it.

Does the remote use 5 digit setup codes? Does it use 5 digit EFCs? (accessed through the 994 command.)

If UEI is telling you to use 5 digit codes, chances are pretty good that this isn't an EEPROM type remote.

It is probably a FLASH remote.

Is this a Universal remote? Is there a manual to tell you how to program other devices? Is there any information on how to do a 991?

What doesn't work?

Tip: When creating an upgrade, always include ALL functions from the oem remote, even if you never plan on assigning them to a button. Complete function lists makes an upgrade more helpful to others.

Here's a link to the user manual for the McIntosh MCD201:
http://www.mcintoshlabs.com/downloads/product_manuals/mcd201om01.pdf

The remote is described on pages 14 and 15. It appears to be a single device remote, so there are no instructions for re-programming it.

What IC do you have plugged in to the 20 pin socket? The pictures don't show one.

Also note that pin 1 though 6 is labeled on the DIY PCB

If the chip is missing, that would explain why the cable doesn't work. But even if the cable were working, if it's the wrong cable for this remote, it won't do you any good anyway.

Is there any chance that you could open up the remote and take some pics of the circuit board?

1) The 20 pin IC should be the Delcom interface chip. Without this IC, there is no possibility that the OS will recognize the interface-- it isn't there! So the vendor has messed this up.
2) The remote uses a flash chip and is not a EEPROM bsed remote. So even if the interface worked perfectly, it would not be able to communicate with the remote.
3) The silkscreen on the PCB says JP1.1. That isn't conclusive, but it may mean the remote is in fact a JP1.1 remote. That would make using a cable problematic, because the JP1.1 remotes were short-lived. I think there is no ready made interface available for those remotes.

So, I think you should try to use EFC keymoves (994 command) to try to get it to work with the McIntosh. I doubt that it makes sense to try to computer program you remote if it really is JP1.1.
