Timebase signal to pfi 0 to 7 pin (register level)

[stuwilkins]

Hi,

I wonder if someone can help me. I am using a PCI-6602 card as a counter/timer. I would like access to the internal timebase signal via a PFI pin so that I can use that clock to sync another device.

I have just got off the phone with NI who were exceptionally helpful and said that it is possible to "route" a signal to the PFI pin.

However, I am using register level programming (as I am in linux) and cannot find any information in the register level programming manual.

Does anyone know how to do this? Or the register that needs to be set?

Many thanks,
Stuart

Hi Stuart-

Which Linux distribution are you using?  If it's one of the supported distros, I would recommend that you use NI-DAQmx 8.0 for Linux.  The functionality to route PFI signals is available in NI-DAQmx via the DAQmxExportSignal() and DAQmxConnectTerms()/DAQmxDisconnectTerms() functions.

Hopefully this helps-

EDIT: If you still need help with register-level programming, please repost your question in the DDK forum so that I can help you there.
