JP1 Remotes

This JP1 stuff has a steep learning curve!!!


Before I make a JP1 cable and attempt the programming of a remote, I would appreciate anybodys guidance as to if what I am going to try and do is relatively simple or not.
I have done the required programming using a Pronto.ccf running on an iPAQ but was not happy with the battery life. Before spending on a Pronto TSU-3000 I thought I would see if a remote which is sitting i nthe cupboard would do what I want!

I have a URC-7541 One for All Digital remote already.

Equipment to be controlled...

Panny Plasma
Yamaha AMP
Nokia DTTV box
Panny VCR
Limit DVD
Denon CD/Tuner

All needed codes have been learned into the iPAQ and are available in CCF format.

The set up would need to use the AMP for ALL volume adjustment, the Plasma input changing as the device buttons are pressed to select the correct input aswell as changing the AMP input and possible turning off the other components?

So can a device set (say TV) have different device codes for different buttons? e.g. volume operates the AMP, Numbers operate the DTTV box and the special buttons operate the plasma aspect???

Is the 7541 capable of doing what I want? is it worth me making a cable?

TIA

IIRC, the URC-7541 is not JP1 ready, it needs to have an EEPROM and 6-pin conenctor soldered in before you can use it with JP1.

When programmed using JP1, you should be able to make your remote do whatever you want. You can certainly do what you describe.

Rob,

Thanks for the reply, the remote has a 6 pin connector with JP1 written next to it under the battery cover, I assumed that this would be all that was needed.
If you think it should be capable then I will make up a cable and give it a try.

Thanks
Simon

If it has the 6-pin connector installed, then it's a pretty safe bet that it also has an EEPROM installed, so go for it.

I have a URC-7541, and it is certainly JP1-ready. There was a bit of confusiona while back, as there seem to be two models of 7541 out there, one with a 1k EEPROM and one with a 2K EEPROM, but my understanding was that they were all JP1 capable. Am I wrong?

Also, bear in mind that there are only 4 device keys on the 7541 to contorl your 7(!!!) devices, so you will have to do a bit of juggling to get the remote to do what you want. Should be fine though!

Thanks guys, it did come JP1 compatible out of the box (mine is 2k).
Programming it works fine, I now just need to work out how make it do what I want!

FWIW mine was badged "One for all 4 digital" and was supplied with my nebula digital TV PC card.
