Hello
Taylor,
Have you been able to successfully start acquisition from an analog trigger (at
your specified level), on just the master device? Verify that you can do
this first before trying to send that start trigger line over a RTSI
line. Take a look at the Traditional NI-DAQ shipping example (Help
>> Find Examples) titled Acquire N Scans Analog Hardware Trig.vi, located
in the NI Example Finder under Hardware Input and Output > Traditional DAQ
> Analog Input > General. Verify that this works correctly for you.
Here is an
example program that shows how to correctly synchronize analog input on two
E-series boards:
Synchronize Two E Series Boards Using PFI or RTSI
Have you
ever considered programming with the NI-DAQmx functions? If your device supports them (which most do),
the NI-DAQmx API is much easier to use, and actually operates more efficiently
on a driver level than most Traditional NI-DAQ functions. There is a good NI-DAQmx shipping example
titled Multi-Device Synch - Analog Input – Finite Acq – Analog Start.vi, that
can be found in the NI Example Finder under Hardware Input and Output >
DAQmx > Synchronization > Multi-Device.
This example shows how to do exactly what you are trying to do in
NI-DAQmx. I hope this helps.
Regards,
Travis G.
