NI-9231 can't find TEDs sensor

[Miroslav_T]

Hello,

I received the Ni-9231 card and right from the start I encountered a problem I can't find the sensor that support TEDS specifically the GRAS 46AE microphone (the NI-9234 card loaded the sensor without problems). I tried to connect the accelerometer PCB and  it works without any problems. Do you know what could be the problem?

Thanks for advice

Doesn't looks like any difference in support for IEPE & TEDS between 9231 and 9234.

How did you connect and test?

I bought a BNC adapter (female end) for the card, so I connected the accelerometer directly to this adapter. I connected the microphone using a BNC cable ( male-male), I tried 2 cables of 0,5m and 1 of 4m length. 

For testing I run NI-MAX and try to find TEDS, microphone itself works if I run it as IPEE sensor.

Wait, at first you said the Mic is not detected, now you say it works. Could you please summarize your observations, status and problem?
