rout board clock to output pin

[WernerGobel]

We are using 3 PCI boards (6115, 6711 and 6534, all configured under traditional Ni DAQ), whose board clocks are synchronized by routing the board clock of the 6115 device to the RTSI clock using the routsignal.vi. For synchronizing an external device, we would need to have the board clock, or the RTSI clock, on an output pin. Is it possible to rout the board clock to an output, for example a PFI pin?

Thanks a lot for your help!

This is possible by using one of the counters on your 6115 and creating a two part route. Using Traditional DAQ, it's a little tougher to do than in DAQmx, but it's still possible. The easiest way to accomplish this in Traditional DAQ is start and event counting VI (Count Edges (DAQ-STC).vi shipping example should work) with the 20 MHz Timebase selected as the input for the source specification. This accomplishes the first part of the route by routing the 20 MHz Timebase to the source input of the counter. Next use the Route Signal VI to route the source of the counter out to a PFI line. If you are using Counter 0, you will need to route the source to PFI8, and if you are using Counter 1, you will need to route the source to PFI3. At this point you should have access to the 20 MHz signal on your PFI pin.

Under DAQmx, you simply need to use the DAQmx Connect Terminals VI and choose the 20MHzTimebase as your source and PFI3 or PFI8 as your destination.
