JP1 Remotes

Hello, Folks,
I finished programming OFA remote, within your so kindfull helps. I do my expressing my thanks to all of you. I wil have no more than one remote, all others will be desarmed. I wish to all of you: Good OFA ! Long life to JP1. Kokalarobia.

Hi, Folk, I made it ! I could do it for a replay-tv, and a dvd player. It was hard. Making the map of each remote, doing learning operations, downloading, uploading, doing difference between address number and code numbers. Every one of this done a ... thousand times !
Thank you.

Hello, Did you put the 2 remotes close enough one to other, far enough, right enough ? Did you have new batteries ? May be you would better retry. Sometimes IR.exe does not show necessary informations (OBC, protocol). Sometimes ago I could not abandon raw learned code, so I could not put all ...

Those are criterias for judging which is the best:
- First of all, the memory space, because there will be no need to make upgrade device, only learning is required. Learned codes may be included in macros. In Logitech Harmony, some remotes have 2 Mo, even 64 Mo.
Standard value for OFA is 2Ko, I ...

You are referring to the setup code in RM ? In that case, it can be any 4 digit number up to 2047 as long as it does not conflict with any other ones you are actually using.
Yes, that is it.
Pardon me, Capn Trips.
I think I shall have to test many "credible" setup code values, those who are in DVD ...

Hello,
I think IR learning operation does emittted IR sampling ; shape accuracy depends on sampling frequency, on distance between 2 remotes, on angles, on batteries charges, ... Then happens Analogic to Digital transformation trough sensor.
It is quite impossible to re-built the same signal shape ...

Capn Trips,
I tried to build a device upgrade for the last four CD lines. I could not bet what device code number to use, as learned IR does not give it. I will think of it later. For now I think I will have to try many values ; First those who are "standard". Have you an advice ?

Hi, Capn Trips,
The four learned keys on the CD device are perfectly good decodes. Build a device upgrade using NEC1 protocol, Device=0, Subdevice and Parm=<blank> and use the OBCs from your decodes.
I am not at home for now, I am in my office. I remember there were many plus characters ...

Hi, Folks,
I made URC-7552 learning 32 functions, from 2 original remotes.

The IR learned area is nearly full of data ! only 13 bytes remaining. And learning operation doesn't success any more. Only 7 bytes remaining in Upgrade.

In raw display :
From the address "0000" to "002F", there are data ...

Hi, Folks,
I opened IR.exe
I suppose I have to add a new device, Here are some questions, How to determine these values:
- What to put into Upgrade Device Window
- What to put into Device Button restriction
- What device type ( =dvd for me but maybe VCR also)
- What Device Setup Code ?
- What ...

Hello, Binky123,
Hi, Mark Pierson,

Here is all what IR Learned Signals windows shows as Signal Description:
. DecodeIR version 2.36
. Phase encoded (RC-Type),
. 19 bits,
. MSB Value= 100 1100 1010 0010 1100
. Frequency = 38095,
. Bi-Phase = No
Thank you for your help, I will use your informations ...

Binky123, You are right.
Unfortunately I don't have a signal analyser. (Even if I had, could I ?) I think it can sense an IR signal. So I could have the signal shape, and therefore delays, and different bits, and at the end, the hexadecimal protocol code and function code.
I think the only thing to ...

Hello,
This :
23 20 1F 00 D2 05 00 9D AE 06 01 3B 01 3B 01 3B
00 9D 00 9D 01 3B 00 9D 00 9E 8D 34 23 41 14 41
23 00
is the contents of learned functions windows, all this is just one button function of the original remote ! It is nearly the same lenght as a whole device definition in the upgrade ...

Dear Zap,
I forgot to tell you. I made this mistake so now I cannot restore factory settings any more.
The first thing to do is to backup up the raw contents of your remote by IR.exe, prior to do anything. Then store the file in a secure place. So you will be able to go back if disadvantage case. Do ...

Where is this discussion going, exactly? Now you are interested in cheap JP1's?
Hi, Dear Mdevj,
As I see, The US has so many JP1 models, it is difficult to me to know how old is a model. So many many ! When I wonder why, I remember that OFA is a US brand. In Europe, RF remote is still an unknown ...
