Is it possible to use the PCI-6602 Board Clock to run a PCI-6115

[msenko]

I would like to synchronize the board clocks of a PCI-6602 and PCI-6115. Using NI-DAQ calls and Borland C++ Builder, I can use the Select_Signal() call to output the 6602 clock on the RTSI bus, but only on RTSI_CLOCK. The 6115 can receive a clock from the RTSI bus, but only from RTSI_0 to RTSI_6. Is there a routing method that I'm overlooking?

Hello;

The trick is to route the internal timebase first to one of the 6602 counters, and then use another Select Signal to route the same counter source to one of the RTSI lines.

Then you can use that RTSI line to be the 6115 Scan clock.

Hope this helps.
