Hello everyone,
i got the MiniTiouner Pro V2 and i am having some errors which i cant explain. I connected the MiniTiouner and initialized it. After that i did the Hardware checks and i keep getting the same errors. On the "Check MiniTiouner Drive and Filters V0.4a" i get the error message:
------ NIM and Demodulator detection ------
Write_register function failure.

Also Demondulator detection and Synthesizer detection are red. And on the NIM: it only shows questionmarks. This is the output of the Test:

Just to be sure i also tried the other Test Programm "Test My MiniTiouner version 2.3 D2XX test". Here i also got another Error. It tells me that there is no NIM when i click the "TEST NIM" funktion. The output message is the following:

i will also add the visiuals of the tests. I double checked all the connections and everything else that came to my mind. But i still can't see why this problem occures

hello,


your NIM is not detected
1) be sure that you use the good USB port ( closest to the NIM)
2) check the NIM voltage : 3.3v ( pin 5 and 23) and 1.1v (pin 25).
3) check the I2C pins on NIM ( SDA and SCL on pins 21 and 22) . The best is to use an oscilloscope to see the signal.

Hello,

thanks for the reply. As for the suggested solutions:

1) be sure that you use the good USB port ( closest to the NIM) --> I used the USB master
2) check the NIM voltage : 3.3v ( pin 5 and 23) and 1.1v (pin 25) --> Measured it and it's all correct
3) check the I2C pins on NIM ( SDA and SCL on pins 21 and 22) . The best is to use an oscilloscope to see the signal --> I unfortunately do not have a oscilloscope. I therefore could not measure the signal.

Is there another way to find a solution?

Thanks,

Hello,

So, it seems that it is the I2C dialog between the NIM and the USB chip that doesn't work.
test and retest the contact of this 2 pins on the Nim and on the USB chip.
it's easier if yu have an oscilloscope.
