[mffa]

Hi
I have 4 912 dongles for tacho universal 2008 and not work
anyone have a good dump for atmel?
thanks
best regards

My cable not work too.
Some people have good cable or know how repair this??

Thanks

It?s the same answer up.
Does not work that way.

Anybody have this cable work fine??

Yes I have, bought a couple from ecutool.com 2 worked fine so I was lucky.

Who can help which resister use for R1 and R2 position

Also I have interesting which capacitor is correct it need or not position of C4 100U/25V

And correct is tantalum chip position is C4 47U/16 V




Please inform me about exact nominal of these parts on work dongle

we have with capacitor

like this



Please help to fix it

this is my dongle

Can somebody explain how to get the dongle work?

When I measure the resistors of mine I get the following values:

R1 = 10kOhm (the smd resistor is labeled with 103)
R2 = 660Ohm (the smd resistor is labeled with 681)

I think that these values are OK, but can somebody confirm it by measuring on a working dongle? Or is R2 to high on mine? Because according the PCB label it must be 560Ohm.

By the way I have soldered a 35V/100uF capacitor as C4.

Is it possible to reprogram the Atmel Chip with X-Prog? Can somebody send the dump and shortly describe how to do.

It seems that nobody has a working dongle

Hello guys,

what was the solution to fix the dongle?
Could anybody of you please give a solution for making the 912 dongle work?
Mine is also not working and has the following details on board:

R2 = 10kOhm (the smd resistor is labeled with 103)
R1 = 660Ohm (the smd resistor is labeled with 681)

I have soldered a 50V/10uF capacitor as C4.

Need the tool really fast... Thank you for your help

I've read all topics which where diskussed in past here on DK. Topics are to old so that all uploaded pics are down and not really helpfull...

I've changed resistor R1 to 561 and R1 is still 103.

Dongle does still not work.
Is C4 50V/10uF right?
Is C4/1 47u/16V right?

Does nobody have a working 912 dongle anymore????
