Thanks for the reply. I ordered the red coloured PCB. It seems to have an RTS pin. I will post after I make the interface.Hope it will work. |

It is working! Now I will try to learn the RMIR software ![Very Happy](images/smiles/icon_biggrin.gif) |

Hi there!
I've just tested my 7140 with CP2104 USB-UART module. It works with RMIR! |

Is there any way to use the FTDI cable to communicate with a JP1.1 remote? (Like hooking up the connectors differently?) I recently obtained a Comcast 1057BG0 and would like to program it. I have cables for JP1 and JP1.3/4 (FTDI) but not JP1.1. Thanks. |

Resurrecting a way old thread.....
I have a modded URC-6131 that back in the day I used to program with a serial JP1 cable. However, said cable didn't make it in my last move, and I have found the need to pick JP1 back up again. So time to modernize!
I order a couple of these:
https://smile.amazon.com/gp/product/B07T8YHBH1/
...which look like they will work, and I'm using Tommy Tyler's document here:
http://www.hifi-remote.com/forums/dload.php?action=file&file_id=10864
to figure out how the wire colors translate. So I need someone to check my math here.
The cables I ordered have the following pinout:
Red wire: 5V
Black wire: GND
White wire: RXD
Green wire: TXD
Yellow wire: RTS
Blue wire: CTS
The style of cable in Tommy's doc appears to have this one, from what I can see finding similar ones on Amazon:
Black wire:GND (pin 3 on 2x3 connector)
Brown wire: CTS
Red wire: 5V
Orange wire: TXD (pin 4)
Yellow wire: RXD (pin 6)
Green wire: RTS (pin 2)
So extrapolating from that I get, for the cables I ordered:
Pin 2: RTS (Yellow on my cables)
Pin 3: GND (Black)
Pin 4: TXD (Green)
Pin 6: RXD (White)
Do I have it right? _________________ Chris Lemon

Well, I wasn't overly worried about having them since they are used with Arduinos as well, but I was able to cancel, so no harm no foul.
Is there a USB cable I *can* mod into a JP1, then?
(Or would I honestly be better off dropping $70 (or less, checking Ebay?) on a XSight, as a JP1 platform?)
EDIT: Yeesh, not even $70, ordered a used XSight Color on eBay for $22. That will serve my purposes (as a platform for programming codes in via RMIR by hand and then teaching other devices) nicely. _________________ Chris Lemon

To use JP1 with an old JP1 remote, like the URC-6131, you need an FTDI cable, like the one you had ordered on Amazon or like this one which is $8.69 on eBay, and a JP1 adapter which is currently $17.99 (they were $9.99 last time I ordered one). _________________ Rob

So you do need one of those adapters, gotcha. Sounds like I'm in a much better spot with the XSight I ordered then; it's not about resurrecting the 6131 so much as having something I can program codes in from "source", as it were, and filling in the blanks Logitech/Harmony can't/won't fix. _________________ Chris Lemon

Okay, so dig this: turns out the cable DID make the move! It is in fact a DB25 cable (male connector, so yeah, likely parallel), and pins 6 and 7 are clipped off. (And for the life of me I don't remember why, if I simply bent them and they're not in use or if there was a reason, or what.)
So. If I DID want to try to resurrect this for funsies, would something like this:
https://smile.amazon.com/Sabrent-IEEE-1284-Parallel-Connectors-CB-1284/dp/B00R654J18/
...be functional with RMIR? _________________ Chris Lemon

Yeah, not sure about that USB to Parallel cable, my recollection is that they don't work, but if you have a spare PCI slot, I think you can add a parallel port that way. The thing is that RMIR uses a process called "bit banging" to talk to the remote through the parallel port. _________________ Rob

Got it. So I'd need to find a cable with a chipset known to support bit-banging (the FT245RL looks like it might?) and even then it's a crapshoot, it's not as easy as "emulate a parallel port through USB." _________________ Chris Lemon

I sent you a PM with more details. But for me, the Xsight is not ideal for your purposes. Frankly, learning with it is a major PITA because it's a multi-step process including the requirement to type in a name for each function on the remote as you go.
And Rob is correct about the USB to parallel adapters. They're designed for printers and simply don't work with RMIR. |

There's no such thing as a single cable that supports JP1 remotes any more, anyone that used to make them stopped a long while back. If you want to use your old JP1 remotes with RMIR, I explained what you need a few posts back.
If you're using a desktop computer and you have a spare PCI slot, you can add a DB25 port by adding a card, like this $13 card on Amazon:
https://www.amazon.com/dp/B07S7SQ24R/
or this $7 card on ebay:

Yep, I did follow, but I'm not interested in sticking another card in my case, so it's not a major deal. I was more curious to see if I could end-around on the adapter having found the original cable while still using USB. Sounds like the answer is no, and that's perfectly ok. ![Smile](images/smiles/icon_smile.gif) _________________ Chris Lemon
