JP1 Remotes

Thanks for your help. It all seems to be working just fine now!

Evidently IR handles this somehow. I had a bad transistor which I found by writing a C program to assert RTS. The interface cable seems to work now.

Hi I have breadboarded a jp 1.x interface using Tommy's document revised 9/28/2008. I am building the transistor version.

I am using IR version 7.14 dated 4/27/2007

Now my question is this...
It seems that the latest plans call for using RTS to reset the remote while the prior version used DTR ...

I am so sorry ... I finally tried to figure out what the big red message "The protocol code below is required for this upgrade" is all about. After reading the readme file I found that it means exactly what it says. I had never experience a protocol upgrade before.

Anyway I copied the protocol ...

Sorry about the missing ir files they are here https://www.hifi-remote.com/forums/dload.php?action=file&file_id=5403 .

The reason that I am using this protocol is simply that it worked. The other codes all were missing something. I do not remember where I found this upgrade but I am sure that I ...

Hi I just got a new urc 8910 and I am attempting to program it just as I have my 6131 and 2133. I am having trouble with the code for my Sony receiver. I use the Sony Combo (12/15/20) protocol Protocol ID 01 27 in keymap master. This first thing I notice is that for the 6131 the protocol ID is 00 27 ...

Thanks for your reply. I will put in new batteries and I will most likely buy another jp1. I am looking at a URC 8910. I have a 15-2133 also but for home theater usage the auto dim is a pain.

Cheers

I encountered this problem again last night. This time, removing the batteries did not help. I downloaded (or uploaded) the eeprom from the remote and compared it. it appears that all of the keymoves and the devices are in there but I just cannot program the device button. The device codes for 2 ...

No I am not running an extender. The batteries seem to be good I did not replaced them and they work for a few weeks. I do use the remote a lot with my home theater.

I have upgraded a URC 6131 with new codes and it had been working fine for at least a year. But lately it forgets the upgrade. By that I mean that it acts like there is no EEPROM. I try to reprogram the device with my upgrade code 1999 and it just blinks twice. Today I removed a battery and replaced ...

With my 6131 I can use a keyname to make a keymove (Using IR 6)
With my 15-2133 there is no radio button for keyname in the keymove dialog so I have to use the hex or EFC

Am I missing something or is this just the way things are?

Richard

Thank you for this information.

Richard

I have done some more reading and have more information.

After the download the red LED on my remote does blink twice.

I can use the remote while the JP1 cable is plugged in.

If I unplug the cable I do not see the led blink.

This it all seems OK BUT the device codes do not get set correctly ...

Hi I am using audio code 1058 which Mike England indicated is a two byte code. I wish to add a keymove using IR but I cannot find how to enter the 2 required bytes. I want to add EFC 173 and device code 0Cx.

How do I enter this information?

Well I am back to having problems.

All went well I even added an upgrade file I had downloaded and it worked. Some keys were missing so I added them and uploaded that to the remote. Now the upgrade does not work at all. it is though the device code had changed.

I just pulled out a battery and ...
