JP1 Remotes

I don't believe and extender has been made yet but was advised that in the RDF there is an entry for a multiplex. Have not come across an unextended multiplexor and can't find a reference to one in the forum so would like to ask if an multiplex upgrade is available and how it could be applied, please?

Are you sure that's not multi-macro? There has never been a multiplexor on an unextended remote.

mjdavej, pity you don't know of any but thanks. [edit: I now see that Vicky confirmed the entry was for a multi-macro and she has explained that a multiplex is said to be a special protocol that allows the user to change setup codes on the fly]. I gather that a multi-macro might be a like a 'stack', where one macro is issued by the first button press, and different ones are issued in turn after that. Have been playing with 5-device 7950 and appreciate its fairly minimal layout, which helps to remember where things are, but would interested in anything to help with that same paucity of spare hard buttons Confused

Not sure if it is possible, or if it would even help, to have a multi-macro on the e.g. tv mode button. At the moment first press does [Tv mode: input tv] but I doubt if a second press would be able to set another device mode e.g. VCR mode, which the VCR mode button can do already...and anyway there are still some shifted keys and phantom buttons to spare...based upon Vicky's earlier remarks, access somehow to a 6th device with spare unshifted buttons for easier access, was what I thought I could do with.

There does exist unextended device multiplexor upgrades but not for the URC-7950. I searched the forum and refreshed my memory on it and the URC-7950 reloads the device table from EEPROM at each key-press. You have to patch this behavior in order to use the unextended device multiplexor. This was done for the RCRP05B here http://www.hifi-remote.com/forums/viewtopic.php?p=94305#94305 .

The unextended device multiplexor just loads a different device code into the device table slot in RAM when you press a designated key.

Thanks Binky, I knew I wasn't going crazy.

Tranx, this is not something we expect a typical remote user to create. I'll see if we can get NBoater interested in this thread.

Tip: When creating an upgrade, always include ALL functions from the oem remote, even if you never plan on assigning them to a button. Complete function lists makes an upgrade more helpful to others.

I have been watching.

For various reasons I have not been doing anything on the JP1 front for quite some time. However, I am now in the process of trying to get everything up and running on my latest machine and will look to finish off and release my URC-7950 extender ASAP. I will then have a look then at the multiplexor for the un-extended remote.

Regards,
NBoater

Hi NBoater, thanks for the good news! Will keep an eye out

The URC-7950 30293029 remote requires a fix so that the unextended device multiplexor will work with it. This will stop it from re-loading the device setup codes from EEPROM on every keypress.

Load protocol and setup code into remote. Press CBL. Press CH+ to apply fix. You can remove protocol and setup code from remote.

Thank you very much for that, the URC-7950 protocol and unextended device multiplexor - I mentioned it to Her Indoors and she seemed very impressed!

Have not ventured into this sort of thing before but have just now picked up some clues while trying to get an extender working for Insignia, so will have a go to see how far I can get and come back...thanks again

Apologies, I tried to do what you said but don't think anything worked properly.

There is no CABL button so tried the others and then CH+

Two items have appeared in protocols but no new options

Looking at your file, I don't see the TV 1107 device. So go to Devices - New - Import Raw, paste in the Upgrade Code2... part, then OK. Then upload and try the CH+ thing again. You can set the TV code back to what it was before when you're done running the patch.
