Disclaimer: I'm not shilling for Rob. I'm simply pointing out that maybe you didn't realize how inexpensively one can get a JP1-ready remote.
Rob has for sale several inexpensive JP1 remotes:
JP1 Ready Remotes:
URC-8910 - $20 (latest B01 version - see note)
URC-8811 - $25 (limited quantity)
URC-6131 - $25 (mod)
URC-6131N - $25 (mod)
URC-6011 - $15 (mod)
URC-8011 - $18 (mod)
ReplayTV (original black 4 dev remote) - $25
URC-9910 B01 - $40 (taking advance orders - see below)
URC-9960 B01 (Kameleon) - $39 (mod) - (see below)
JP1 Cables:
"Simple" parallel - $15
USB Cables - $35
So if you think the new cable and software are (a) likely to be that much cheaper than a $15 to $25 remote and (b) worth the wait and wrestling with a "coffee table full of remotes" until then, I guess that's your choice.

Any updates on progress with the JP1.2 interface or software yet?

So everyone is in the loop:

and this...

After reading the hardware document that Tommy T. put together, I realized that my fingers are too fat to slap those components together with SMD components. Can someone put a list together for a through-hole PCB box using Mouser or Radio Shack parts for the electronically impaired? Preferably RS so I can get them locally.
Q1-Q4 =
C1 =
D1-D3 =
The resistors are the easy part.

RS part numbers.
Q1-Q4 = Either #276-2058 or #276-2016 which are 2N4401 or 2N3904 respectively
C1 = #272-1069
D1-D3 = #276-1620 which is a pack of 50 but I can't see an option to buy 3 individual diodes cheaper than these

Thanks Curmudgeon
Did you build an interface with these components with success?

No, I have an 8910 (JP1.0).
I haven't seen any of these new fangled remotes down here in the back docks.
The circuit is very straight forward, there are no special requirements for the parts so I don't think you should have any trouble.
Let us all know how you go.

I ordered the 6820, 8820 and 10820. I think the RDFs need to be built. I may need help in the IR software end, but I'm willing to contribute once I get the two talking. I've got the JP1 end figured out on the user end so hopefully the transition to JP1.x will be fruitful.

Check the in
JP1 File Section ->

RDF Files
Check there for images and maps too.

We've already got beta support for the 8820 and 10820 added to RM & KM, but I don't think anyone has done an RDF for the 6820 yet. My guess would be that it is the same as the 8820 except for some missing buttons.

How is the testing going so far? I haven't seen anything posted on the results other than they got the circuit figured out.
Are extenders for the fast macros and all the good stuff planned for the near future? It's too bad I don't know machine language to help create the code. I learned it once for my RS CoCo3 (6809) in 1988 when I was in 8th grade, and that was a long time ago- 1Mhz (2mhz in turbo) . It was a smokin' machine.

The board inside the 6820, is the exact same one in the 8820. Only thing different between the two is outside casing, on the 6820 the CD & AUX devices are hidden from sight.
Help.

I based my design on Tommy's SMD and skematics from here.
https://www.hifi-remote.com/forums/dload ... le_id=3228
and I used the parts list from Curmudgeon after a trip the RS...

I am using IR7Beta2 to see what it will do on my new 6820. I plug it in and the led on the remote stops working when I push buttons (I don't know if that is supposed to happen or not, but the led works on my 6131n with my jp1.0 so I figure it's a bad sign). IR7 does not see the interface working. here are pictures of my board.

Any ideas? or is JP1.2 still too beta and I should hold my horses?

They have a new design. That design was causing problems.
Figure 6 shows the first version of the interface to combine support for JP1.1 and JP1.2 without switches. A number of these were sent out for field testing, and problems showed up immediately. The connection between pins 7 and 8 of the DB9 connector were to provide a loop-back feature to enable software to find which port the interface is plugged into. Apparently that is a "no-no" with the Windows API, because it causes the interface to fail communications. Also note that pull-up resistors previously used on Rx and RESET were eliminated to reduce component count. One result of this bad judgement was that some remotes would occasionally reset spontaneously due to noise on the floating RESET line when Q3 was turned off. Also, the internal pull-up on the Rx line in the remote processor is very weak, giving a poor rise time to the data signal. Pull-up in the JP1.1 processor is the worst, and is so weak that there was almost continual comm failure.
Send Tommy an message. I don't want to pass on the updated document without his blessing. I built it last night, but I haven't got the newer remotes in my hand yet.

Thanks JS, I'll drop him a line. Maybe there is a way for me to help, but probably not as I have just enough knowledge to bearly exist. I kind of skip along in blissful wonderment, but I also have too much impatience and a need to poke at things with a stick.
