URC-9960 telephone upgrade problem

baczek · Post by **baczek** » Wed Sep 19, 2007 3:24 pm

I have called tech support, obtained code for my equipment, and got wav file by email.
Problem is I can't enter program mode.
After pressing setup and entering setup mode, I supposed to press "other" once and enter "997". The IR should blink twice and screen should go blank.
In my case after pressing 997 it goes back to setup right away.
I have tried to reset 981, but no go.
Seems like my unit won't recognize 997 in setup. It does recognize other codes like 994 for example.
My unit model number is URC-9960 BJ3.
Do I need to enter different code for modem programming, or this unit is not programmable by modem?

Never heard of this model of remote, are you sure of the model #?

the BJxx designation on the end of the URC-9960's indicates which EEPROM type is installed, you can ignore that (although some of them will give you fits with different JP1 interfaces and IR)

I don't have the book so I don't know what a 997 code will do.

The 981 reset should blink 4 times and then return you to the screen with "other" on it. Once this happens, the remote has done a factory reset
(I just verified this on my URC-9960-BJ5 that I have here in my office)

My 9960 blinks two times fast and one time long blink, when 981 is pressed.
997 code was given to me by tech support people for upgrade by modem.
It just blinks once (long) and goes back to setup screen.

I think this generally indicates that the remote can't talk to the EEPROM, because it's faulty or "disconnected" (bad solder joint, circuit board fault etc...)

I'm not sure if there are other causes too.

Does your remote still have warranty ?

Can you try taking out the batteries for a while, then pressing some keys (with batteries still out), then reinserting the batteries and trying 981 reset again ?

This discharges the remote before the reset, and has helped me out a few times.

When you say the remote

"recognizes 994"

- can you actually perform keymoves ? And do they work afterwards ?
I ask that because keymoves are stored in EEPROM too, so that would be odd.

If the behaviour persists, to try to confirm an EEPROM fault, see if learning commands from another remote works or fails - learned signals are saved in the EEPROM, so if it's faulty this should fail too.

My understanding is that EEPROM stores this part of library which is not factory default.
So, to check EEPROM, I have built parallel JP1 interface, open IR program and test the interface. Test was OK.
Then I've used the wav file to upload data to remote.
Everything went OK.
Then I've downloaded data from remote to computer and it was the same as this from wav file.
Does this experiment proofed that EEPROM works?
Why then I can not use "other 997" method?

SETUP-997 is to prepare for modem download. Maybe your coil on the remote is damaged and can't receive the data and so it returns to the setup menu?

I have measured coil continuity - it is 53 ohms.
What I have discovered that the LM339 quarduple op-amp does not have any power supply.
My understanding is that this op-amp is amplifying signals received from the coil, but it is only active in modem receive mode (otherwise power is cut out from this chip). I am still not sure if this is firmware problem. I don't have a diagram to troubleshoot hardware.
I hope my JP1 interface will help me bypass this problem. I am going to test it soon.

Yes, I believe two pins are used - 1 to provide power and enable the modem when SETUP-997 is pressed and 1 to sample the modem data.

A JP1 cable can modify/replace the same EEPROM data as the WAV modem data.

I have tested uploaded upgrade, but it doesn't work.
I have loaded code 1217 through JP1 interface, and I am sure is stored in EEPROM, because I can read it back.
But when I try to load 1217 in setup as TV device code I just got single blink.
In fact I have checked the content of the EEPROM and tried some other codes which were there, but none of them could be loaded as device code in setup.
I can only load default codes.
What that means is that EEPROM communicates with computer through JP1 interface, but it doesn't talk to remote at all.
My question is am I doing something wrong ? I don't have experience with JP1 interface and IR program, maybe I am missing some important steps?
What would be the reason that device code loaded to EEPROM from supplied wav file would not be recognised by remote? Am I missing something?

I'm reading this as you trying to assign the upgrade to a device key by using the SETUP key on the remote.

This is a perfectly fine way of doing it, and should work, but you can also assign it on the "General" tab in IR, by typing the number in the field next to the device key you want it assigned to, before you upload with your cable.

If I've understood what you are saying correctly, it would be interesting to see whether doing it this way made any difference.

Having said all of that, it IS beginning to sound as though your EEPROM is communicating OK with IR.exe through the JP1 pins, whilst it is unable to communicate with the processor.

(The processor, as I understand it, is not involved in a JP1 cable upload, IR.exe deals directly with the EEPROM via the 6 pins - so uploading and downloading upgrades would work fine - your problems would start when the processor attempted to read the EEPROM in normal use.)

That would lead me to think of a circuit board problem.

Did you try any 994 keymoves, or try to learn any signals, to see if they get saved to the EEPROM ?

Hey baczec

Did you ever work out what was going on here ?

I was just looking through my old posts and noticed this one was still "up in the air"

I had the same problem with my URC-9964B00.
Not accepting the Prepare for Wave (Setup-Other-997). After the Factory Reset (Setup-Other-981), 4 Blinks, then Prepare for Wave (Setup-Other-997) was accepted, the remote went blank.
I played the music for an Entire Image, took several minutes, then Setup blinked twice. Hit Home and the upgrade & programing was complete.
Good program, works just like I had the JP-1 plugged in...except for the awful beeps and screeching.
