Re: What Kind of Cable to Buy and Where to Buy It.

Why? It comes with individual DuPont cables. The only pin not together is RTS which is just on a different header. No soldering required.

The sabotaging is widely reported as FTDIgate. https://hackaday.com/2014/10/22/watch-that-windows-update-ftdi-drivers-are-killing-fake-chips/ and they did it ...

Re: What Kind of Cable to Buy and Where to Buy It.

Would CH340 based serial work too? https://www.amazon.com/DSD-TECH-SH-U07B ... B09CK79B4C

I am reading about FTDI and I don't agree with their measure of sabotaging counterfeit equipment and punishing their customers who may not know they are using fake chip.

Re: Issues getting FT232RL JP1.X interface working

Incidentally, I came across this thread. I have the exact same board (bought from Amazon https://www.amazon.com/dp/B0DXT54KHT). And I am also faced with the "Remotes not found" error when using RMIR. My remote is RadioShack 15-134, fully functional, connected with batteries inside.

Re: Trying to program my RadioShack 15-134

Yes, many buttons on my URC-6131 is unresponsive. But over the years, it has gone through a lot of abuses and eventually it cracked. At the time, my fix was to JB-Welt the case back together. I don't think I can open it without cracking the case again. I think it is time for it to go.

I am going to ...

Trying to program my RadioShack 15-134

I have been using a URC-6131 for 20 years. I program it with a parallel cable and I have my Windows XP machine for it. The software is IR.exe, I think v7.15. The remote is failing and I need to replace it.

I have a RS 15-134. Unfortunate for me, I found out it is using JP1.3. So I bought an FTDI ...

Folks, would one of these work as a JP 1.3 cable?

If it is truly just $10, I am willing to give it a try. But where is this $10 JP1.3 cable?

I bought the 15-134, over a decade ago, as a backup for my go-to remote, which is a URC6131. But lately it is acting up. So I break out my brand new 15-134 and hoping I could programme it.

If my parallel JP1 cable is not compatible, I would be really disappointed. I don't think I am willing to ...

Re: New Radio Shack 15-134


EDIT: Finally got one and finished up the RDF. Actually nicer than I expected. The device buttons have led's so you know the active device, and the number keys have letters printed above them for easier searches on DirecTV DVR's. It also has a hidden Home Theater mode as well as 3 additional ...

Returning user. Confused.

I have been using JP1 for 20+ years and I use IR to manage my remote but I have not been using it lately. I used to have a One-For-All URC6131 but the remote is failing (it would suddenly stop responding and requires a power reset) and I need to find a replacement.

I have previous purchased a ...

Apparently this device needs to see some repeats before it reacts. So you could tweak the protocol to send a few more frames.

Try this protocol. it sends a minimum of 3 repeats. See if that helps.

I am not sure. But the mouse directions for the combined remote does not work for me.

I think it has to do with limitation of my remote URC-6131n. I know that the URC-6131 cannot support 2-byte keymoves. Not sure if it is the case. Hopefully someone can confirm.

If I download the mouse only, it ...

Upgrade code requires long press to work

Hi, I recently downloaded upgrade code for a PC remote control:

https://www.hifi-remote.com/forums/dload.php?action=file&file_id=6172

I programmed them on my URC-6131n. The key works fine. But for some reasons, I need to press the key longer (about .5 sec) in order for the receiver to log my key ...
