Which cable for a Comcast M1067B3 remote?

I'm looking into ordering this cable http://tinyurl.com/99gdnq once I confirm it's the correct one.

Here's a picture of my connector http://img101.imageshack.us/img101/6070 ... 506gx4.jpg

By the way, I have three Cinema 7s. They have four learning buttons, but I think they require a different cable, and I don't know if they're capable of handling all the IR signals of modern remotes.

If your PC has a serial port, that cable is indeed the right one to get for your remote. If you don't have a serial port, you'd be better off getting a USB "JP1.2/3 (Flash)" cable from Tommy:

If the Cinema 7's have learning buttons, it means they are the URC-7800 model, which is absolutely JP1 compatible, but it requires a traditional JP1 (EEPROM) cable. It also requires you to solder in a 6-pin header as for some reason it's missing from this remote.

As for it's ability to learn signals, there's nothing special about the signals used by modern remotes. The signals used by your Sony device use the regular SOny15 protocol which has been around for years.

Yes, they are model URC-7800B00

Thanks

Now I'm thoroughly confused.

Before I posted about trying to figure out if I had chosen the right cable, and before I had gotten your reply that the cable I was looking at was the correct cable, I had emailed the guy at diygadget and sent him the same links I posted -- the link to the cable and the link to the picture of my remote's connector.

Here is his reply:

1067 is a Jp1.1 version, It won\'t work with JP1.2 cable.

The cable has been ordered and is on its way.

There are several different Comcast remotes that all have the 1067 model number, most of which are JP1.2 or JP1.3, only the earliest models would have been JP1.1 and they are very rare now.

You posted a picture of your JP1 connection that shows quite clearly that you have a JP1.3 model:

I don't know why DIY is assuming that you have an old JP1.1 version.

Thank you. I thought it had to be the right one given the version number printed on the circuit board, but I've also read that the numbers printed on remote circuit boards are sometimes wrong. That's why I asked originally.

I have heard of JP1.1 remotes being labeled as JP1, but I haven't heard of JP1.1 remotes being labeled as JP1.3, so I think you're safe.
