synchronize Motion velocity with DAQ analog signal

[chia]

Hi Everybody

I am acquiring analog signals using hw trigger and external clock with C and A signals of a 1024 counts TTL encoder.
Now I want to measure the rotation speed of a shaft. I have a Flex-Motion board with which I want to read the velocity (or the same encoder), but I don't know how to synchronize each scan of the analog signals with the velocity signal for that instant.

I can´t use RTSI bus because my Motion board doesn´t have RTSI connector.

Software and hardware:
LabView 6i (v. 6.0.1.b3)
DAQ-Board: PCI-6023E, NI-DAQ 6.8.1, MAX 2.0
Motion board: PCI-FlexMotion-6C, NI-FlexMotion 5.0.1

Thanks a lot for your help.

Hi chia,

with the hardware configuration that you have, I think it´s not posible to synchronize both boards due to you cannot share the same clock source (not RTSI on the motion board).

Sorry for the delay 🙂

Diego,

 I desisted from using the FlexMotion board. Now I am measuring the shaft´s speed with external elements.

Anyway, thanks for your answer and your help.
