JP1 Remotes

I have been looking at various posts about interfaces and have a JP1.3 remote. It seems that the interface is basically a serial or usb to 3.3V ttl circuit. Since I have several serial to ttl boards for 3.3V microprocessors is there any reason why these won't work (with the proper connections of ...

I have a couple of these. They are great but I never got around to putting in the JP1 connector. Now I need to set a button to toggle which I don't think I can do without the connector. But the thread is so old the pictures of jherrick's mod don't show up. Any way to get those? I tried the wayback ...

Thanks. I got 20717 to work on the 3rd try. Part of the issue is that the remote has limited functionality (power is a manual button only, for one). I finally did some side by side tests with the original remote to make sure the functions I was trying worked with the original remote.

I picked up a couple 15-100 and may add the JP1 connector. But for now I am just using the built in codes. I have a DVD player: GE1101PB. I have tried the codes listed (20522, 20815, 20717) but no success. Is it possible that another code would work or do I need to use JP1?

I have noticed that ...

Looking for discrete codes for on/off and also input selector (tuner or svideo inputs). I have tried using channel +, entering channel numbers. They don't do anything while in direct video input mode. It also remembers what input was selected through power off/on cycles so I can't get to a known ...

I have added my equipment to the OP.

There is no zip file associated with the TV text file I downloaded so no explanation. Maybe this is non-standard...

I found the file here for the tv but I am not sure what to do with it. I am just trying to get started with JP1 stuff. I know the file is to be loaded into a program but I expect a few things could be learned just by looking at the file contents with a text editor.

Look here in the file section or remote central for discretes, or post your equipment list and we can help. Just knowing the manufacturer will get us in the ballpark (i.e., sony nearly always has discretes).

The input is no problem either. If it has discretes, then problem solved. If it doesn't ...

I don't really see how to do it without some method whereby the remote can sense the state of your equipment. I have built 2 systems that are state sensing and I never even considered to put that into the remote. Using a PC to do the state sensing, is the equivalent of swatting a fly with a cannon ...

I am wanting to make the remote easier to use for improved WAF. My idea is to make each device button sent codes to set up other devices properly. For example, to play a DVD the DVD needs to be on, the TV needs to be on and the TV needs to be using the svideo input. All these are toggle functions so ...
