JP1 Remotes

After difficulty locating the correct schottky diode, Tom (Filebug) was so kind to mail me one. I received it today - Thanks Tom.

Since I had some down time waiting for the diode, I went back to review to simple interface documentation again. I realized that I missed what could be a very important ...

OK, here's where we stand.
I now have two JP1 interface cables, one with 10K resistors and one with 1K resistors. Both have the the original non-Schottky diode. I'll say I did this for experimental purposes, but really I just didn't want to drive somewhere to get the Schottky.

Both cables work ...

Hi Rob,

Looks like I made the cable before the 1K resistor/Shottkey memo came out.
Here is the parts list I used:

ITEM QTY DESCRIPTION
1. 1 DB25 male connector with either solder pins
2. 1 DB25 connector hood
3. 1 Signal diode, 1N4148 or equiv. (Radio Shack 276-1122)
4. 2 Resistor, 10K 1/4W (Radio ...

Hello all.
I'm having the same "no connection" problem via my laptop's parallel LPT1 port.

Additional info:
- I have two JP1 remotes (RCU810 & URC-8910)
- I have two PC's (whitebox desktop running XP SP2 & IBM laptop running XP SP2)
- Home-made (Simple?) JP1 cable (parallel port)
