routing RTSI to Gate Ctr1

[EP000]

Hello,

I'am using CVI with a 6251. I'm trying to route a RTSI line to the gate of counter 1. I want to know how many pulse on the source pin PFI4 occur during one period of my signal on the said RTSI line. The documentation on these operation is quite limited (or I have not found it).

I have tried to route the signals (RTSI->gate counter 1) but get an error when a measurement is attemped. The error msg says that the resourses are reserved.

Thanks

EP000,

According to the documentation Counter 1 Gate is mapped to PFI 4 on your 6251.  Using the function “DAQmxConnectTerms” you can route a RTSI line to PFI4. 

 

For more information on DAQmxConnectTerms function refer to the CVI help for a list of parameters and their values. 

I hope this helps!
