WHAT type JP cable for what remote? (7950 in my case)

Hi, Wouldn't it be a good idea to create a table of what type of JP cable the different model of UEI or OFA remotes need? I want to make a cable for my 7950, and don't know which type cable I need.

WRT the 6 pin connector to the remote, if you only have one with 8 or 10 pins, even the 10 pins version may work, it should be possible to use a sharp knife to carefully cut away just a little bit of plastic on one side of the opening around the 6 pins in the remote. Or maybe a plier to break off a small piece may do the trick too. I haven't tried it, but will soon.

Although it doesn't have your remote on it yet, there is just such a chart. Perhaps you could make it your festive mission to search out other remotes and their cables and suggest them for inclusion.

I am afraid i am not in a position to be of much help with respect to supply any info, but I would gladly have done so if I could.

WRT the chart, I presume 'Yes' means it is a JP-1, while YES/1.2 means it is either 1.1. or 1.2, where a JP1.x cable should work.

Will I have to make one cable first to see if it works? And if not, build the other cable?

Did you see this thread ? It's not conclusive whether youre remote is JP1 or JP1.x. When did you buy it, as this model been around for awhile or is it new say within the last year or so. If so, then I'd bet JP1.x As it's a European model, maybe one of our europeans expers can chime in.
Best,

What does it say next to the connector? Although not ALWAYS definitive, there's no reason to reject that labeling outright.

You can always open up the remote and see what processor it has, and then one of us can tell you which type of remote it is. A JP1 will have in addition to the processor, a separate EEPROM, whilst a JP1.x will only have a processor. (Now some JP1 remotes only have theprocessor and need the EEPROM added, but the info on the processor will tell any expert enough to figure it out.)

Got it this week, and tnx for info about how type may be determined.

The URC-7950 is JP1.2 cable.

Thank you, I was hoping for that.

Apparently as we've just discovered it may be JP1.3 but the cable is the same.

Ok.

I have recently purchased the URC 7950 remote, and I have been able to download from the remote using IR. I am using the revised JP1.x serial interface on a Keyspan serial to USB adaptor. I originally tried a simple parallel adaptor, but could not get this to work. Unfortunately I cannot find a remote definition file for this remote, and I don’t know how to write one yet. Can anyone offer some tips on writing RDF’s?

An RDF for the URC-7950 is available here.

Awesome. Thanks heaps. I can now successfully download and upload to my remote. I am very much a beginner with JP1 programming.
