Woodstock SQR 88 Dump

[guloe]

Hi guys,
I am looking for a dump for a Blaupunkt Woodstock SQR 88. In the net I found one with code 0663 but with this dump the fan runs constantly. I am also loocking for a operation manual as a PDF or so for this device. I hope one of You can help me. Thank You very much.
Regards guloe

Thank you. I have tried it. It matches bit for bit my other dump, just with different code. I have a phenomenon with two devices after decoding. The fans are running all the time. The NTC for the power stage temperature is evaluated. When it is not connected, I have 5 volts at the input of the processor and the sound is muted. At approx. 4.5 volts, the tone comes on and the fan starts running. So the NTC is evaluated and the switching stage works. Does anyone here know if the fan has to run constantly? Then the NTC would not be needed. Or can the fan be programmed?

Hello,

can anybody tell me, how I can dump my SQR88? I disconnected the relevant pins of the processor, but I don´t get any connection to the chip with my USB TTL board.

Which progam work easily?

Kind regards
