JP1 Remotes

Took delivery of my Hovis cable a couple days ago, plugged between my 7800 and parallel cpu port. Worked nicely, but all of a sudden this morning it won't interface. Tried it on another computer; same noresults.

Any chance wires/connectors have come loose in the cable? How can I test or inspect for failure points?

Yes, I'm a novice. That's why I bought a premade cable. Sure appreciate any thoughts.

Have you tried without batteries in the remote?

On your suggestion, just popped the batts out and tried - same "no response".

Keep the suggestions coming. Thanks for your interest!

Are you using a printer on the same port? Sometimes, a printer driver can take over the port. Reboot the PC and try again.

Actually because it stopped working on my desktop I installed the software on my laptop with the same noresults. I'll reboot to see if that helps. BTW, I checked system-devices-properties for the parallel port to confirm I'm using the correct port address. Although this shouldn't have made this thing work then quit.

Keep your thinking cap on!

PS: while typing this response (on my desktop) I rebooted the laptop - no dice.

Also, I've got the transmission delay set to 1600 (although it worked originally a 0).

Here's an update. Got tired of messing with it last night, so tried again this morning; still get "no response" message.

BUT tried uploading anyway and it appears that the codes are being uploaded (even though I get the response error message)!

Try turning off all error messages and see if it uploads and downloads correctly

You mean check Advanced-Suppress Messages? If so, I tried it and get the "No Response" message and it does not download anything.

Also, above I said I thought it was uploading, but I think that was wishful thinking. It does not appear to be up or downloading.

this is directions for the simple interface but there are also some troubleshooting tips

Thanks for the tip, but I've already run through all but checking the cable wiring. I think I'm going to get another remote and see if it works; that'll probably be the easiest way to tell if it's a failure in the cable.

Again, the real mystery is that it worked fine for a day or so; then kaput.

have you done a factory reset ?

No, I'm a little reluctant to reset and loose all the memorized codes still working in there, until I'm fairly certain I can get the interface to work.

I hope to soon test the cable on another JP1 remote to see if the issue is/or not with the cable. Let you know.

My experience is that each combination of a JP1 RC model and PC has a unique "sweet spot" regarding battery voltage that allows it to communicate successfully with a given PC. Aside from trying "with" and "without" batteries, have you tried with "weak" batteries vs. "fresh" batteries? I have several JP1 remotes that only communicate with IR with fresh batteries, some with weak batteries, and some with no batteries.

You can simulate "weak" batteries by reversing one out of four fresh batteries for the up/download.

Yup, I tried weak batteries. But again, in the morning a few days ago the setup worked fine and without changing batteries later that same day, poof.

Thanks again for your interest.
