PXI-6624 only writes one sample in pulse mode

Hello all

I am trying to write a pulsetrain to the counter output of a PXI-6624, however only the first sample is ever written.

My pulsetrain has 50 samples, and with simulated hardware the output "number of samples written per channel" matches that. If I build the application and run the program on the target system it only outputs one sample indefinitely and also "number of samples written per channel" is always 1.

I tried adjusting the value for "numSamplesWriten" in "DAQmx Write (Counter 1D Time 1Chan NSamp).vi" to a non-zero value without any influence. The timing is set to 50 samples in continuous sample mode with implicit timing.

What am I missing, how do I get the counter to go through the array of samples one by one to output the desired timing series?

Thanks in advance,

Raphael
