Hello,

Is it somewhat possible to connect a serial connection to the NI DAQ (cDAQ9171) and the input being a non-NI product ?

Please be more specific. Your request is too general. We need more details.
What do you want to connect where and how.
What do you want to achieve?

OK,
So I have a 3-axial (WIRED) IEPE accelerometer connected to my NI DAQ then to the PC with LabVIEW.
My objective is to make the system wireless, so I thought of buying 2 MCU (STM32) with a wireless module embedded, connecting the accelerometer to an MCU, and connecting the other to the PC (or my DAQ). So with this configuration, the MCUs are Sending/Receiving the sensor's data, and the MCU connected to the PC will simulate my sensor.
Do you think STM32 will do it? And what's the rate of difficulty. I will attach the accelerometer's datasheet also for you to take a look at.

Standards I'm required to meet:
  1. 12-bit ADC
  2. minimum 20kHz sampling (Ksps)
  3. -30dB attenuation at half of the sampling Frequency.

Hello,

The cDAQ9171 seems to be an interface for one card:

It will need an USB port to communicate.

Can I do it without the DAQ?
Because I will process the signal of the sensor, and send it to the other MCU. So can I retrieve the signal of the second MCU with a PC, and use this data in LabVIEW? What do you think?
