The author of a code library for sending, receiving, and decoding IR signals uses an Arduino compatible microprocessor platform. [Link: tech.cyborg5.com]

From time to time people ask me how to support new protocols that I don't currently use. They sent me what are called UEI codes as examples. I know that it refers to universal remotes with something called a JP1 chip in it. With the proper FTDI/USB cable you could re-program these with codes from a variety of sources. Personally I've never had a need for one of these but I like to be able to support my users.

As I've gotten into researching it I see there is now JP1 .2 JP1 .3 and God knows how many other varieties. Most of the information is really really old. It talks a lot about RadioShack remotes.

Could someone point me to a current inexpensive remote that can be programmed with one of these tables and pointed to a source for a cable. I don't want to waste my time and money by the wrong thing.

What should I buy? Be specific. Provide a link if you can.

I'm not quite clear on your goal (testing?). You can load, analyze and use UEI codes without any physical remote at all simply by using Remote Master and IRScrutinizer and possibly the Simpleset website. Scrutinizer will convert UEI codes to/from almost any other format you can imagine.

An FTDI RS-232 cable from ebay is essentially a JP1.1/2/3/4/JP2 cable compatible with most JP1 remotes made in the past 10 years or so (about 50 models to choose from). The old Radio Shack remotes were JP1. That requires an additional adapter with the above cable. Many newer JP1 remotes don't require a JP1 cable at all but use a standard USB cable, usually included with the remote.

The best of these new USB JP1 remotes would be the Nevo C2 (can't miss it on ebay) or OARUSB04G (found many places). A traditional JP1.3 or later remote would be any of most cable remotes, like a silver Comcast or Atlas from other cable companies. If you want to pick one up off the shelf at Best Buy, get the Insignia NS-RMT415.

Here's a JP1.3 cable I've bought in the past: [Link: ebay.com]

One Nevo C2: [Link: ebay.com]

OARUSB04G: [Link: ebay.com]

Insignia: [Link: bestbuy.com]

Comcast: [Link: ebay.com]

Atlas: [Link: ebay.com]

Here's the complete list of JP1 remotes by type:

(All 6-pin and 5-hole remotes in the first list use the cable linked above. All USB ones use a standard USB cable)

Thanks for the reply. I've ordered a Nevo C2 from eBay using the link you provided. I like the idea of using a USB remote rather than some strange other cable. I can get the software you spoke of should be able to figure it out from there.

I just need a working remote that I can load UEI data and create a real signal from it that I can then capture using an Arduino microcontroller and test my software to see if I can decode it.
