JP1 Remotes

ok
I have built the simple interface I found all parts i needed in my bedroom .

it looks like I have a few unlisted devices which hopefully I will be posting codes for soon.

i am a little stuck now.

i have successfully downloaded the current data on both my remotes with Ir.exe and saved them as text files but RM doesn't appear to understand the file format. what am I doing wrong?

I have a VCR setup with advanced codes to map in things like video plus
make the AV button act as an AV button things like that.
I think the sanyo vhr 789 will be the first upgrade i will post however, is there a quick way to take my VCR settings and convert them to an upgrade for any remote?

I am totally confused about the protocol thing I think 0104 is using 00F0
but Sanyo isn't listed so is it a case of trying a maufacturer at a time and finding who else uses 00f0?


will I need to upload my original dump from my remote back to it if I mess it up entirely.

am i right in thinking if the device is in ROM you cant just pull it out with Ir hack in your advanced functions and create an upgrade?

so using the sanyo code 0104 isn't possible as the basis of an upgrade
but could i use my other learning remote to learn the codes i have for the modified 0104 and create a new upgrade from that?

hmm maybe it might work

The JP1 tools can't be used to extract any of the built-in setup code details. There are some alternative ways to get this.

First, check the File Section to see if there's already an upgrade for your device. If no files are found, see if there's a set of advanced codes available. There is one for VCR/0104 that should help get you started.

You are CORRECT, sir!

That will PRECISELY work (in addition to what Mark answered to you above - it appears he may have been writing his response as you were typing your follow-up).

OK i think i have this 99% figured out.
as an example to others using my Sanyo VCR
i did the learn a code routine for the power button and assigned it to button A
https://www.hifi-remote.com/forums/viewtopic.php?t=3943

I then downloaded from this remote using IR.exe and it had learnt
VCR:A
entry 1
Protocol = Nec1
Device = 49
subdevice (nothing given)
OBC =91
Hex CMD = 25
EFC = 235

going to this page since i know that 0104 is the device http://www.hifi-remote.com/cgi-bin2/ueic.cgi?VCR_0104
when i look for the word power i find 235 = Power.
I know I won't find such a useful page for every device but when you do it helps


http://controlremote.sourceforge.net/rmhelp/rmhelp.html
explains things but i didn't really understand it at first.

switching to RM i can now start to develop my upgrade
i select a remote corresponding to the remote i want an upgrade for

using convention (add 1000 to the existing code) i should make my setup code 1104
i select NEC1 as my protocol (from Ir)
and device type is VCR (its a sanyo vcr)
on the functions tab i find a line for power and enter 235 in the EFC Column soon as i tab from there the other 2 numbers get filled in.
the slow way to fill in the rest of the table and any functions is to learn them from my existing remote or if i want to guess
http://www.hifi-remote.com/ofa/advanced.shtml
(basically press setup and enter in 3 digit codes from 000 to 256 and see what happens)

lucky me i don't have to guess codes or learn codes because
http://www.hifi-remote.com/cgi-bin2/ueic.cgi?VCR_0104
gives me a list of codes for 0104 and a useful name for each code
the numbers are EFC numbers which are the same numbers you guess at
when you enter a 3 digit code.

OK assuming i have entered all my codes the next stage is to map my functions to my remote. some can be done automatically the rest is up to me to find a suitable button.

the layout page has a pic of my remote and i can drag and drop the functions on to the remote.

the output tab has a thing called device upgrade code i copy everything in that panel and

switch to Ir
choose the device panel select add and paste the device upgrade code into the top panel of the window that appears (keyshifts are automatically put in the bottom panel).

i then should have a new entry for 1104 and if i select upload to the remote my upgrade is installed and my new codes will be in place when i press VCR button (provided my VCR button on the general page has 1104 as device code on the VCR.)

thinking a little about this it might be possible to make a macro to switch a device key from one device to another. thus allowing more devices to be controlled by the same remote ... maybe.


I do have one question left thou

when you go to the device tab of IR and click add in the "Upgrade device" window the middle pane has the heading device and a tick box with protocol >FF

I understand that most of the settings within device are set automatically when you paste in your codes from RM but the protocol tick box is that automatic too?

Thank you to capn trips and mark pierson for posting in this thread and helping me to an understanding of how this all works

and of course thank you to rob for hosting such a fine and useful site.

the key concept you need to understand its basically a 1 direction process
you go from generating or loading an upgrade in RM to pass to IR to be uploaded. The only easily understood thing you can get from IR apart from a backup prior to playing is the learned function tab since this gives the protocol and an EFC number for a particular known function.

I don't see a way to go backwards through IR since probably your using a device code in ROM which you can't read directly through JP1.

Just FYI, the process doesn't have to be this complicated. If you look in the file section you will see that there are 3 or 4 upgrade files for Sanyo VCRs and they all use NEC1 with a device code of 49, so I'm guessing that any one of them will work for you.

It's not uncommon for people to want to follow the UEI code, VCR/0104 in this case, but that's really not necessary in the JP1 world. It's usually irrelevant to us whether UEI has assigned a code number to something as long as we already have an upgrade file for the device in question.

Where UEI codes come in handy is when we don't have an upgrade and the user either doesn't have the original remote or doesn't have a JP1 learning remote, in a case like that we will track down the data for the UEI code instead.
