counter pxi-6221 - some elemtary qestions

I've made the needed change from the regular Start Trigger to the special trigger needed for counter input measurements -- the "Arm Start" trigger.  It's only available through the DAQmx Trigger property node as shown.  I'm assuming that your task is configured properly otherwise.

Hi,

thank you very much. Now there is now error occuring anymore. But now there is no triggering. As soon as i start the vi the measurement starts. The start trigger node says always "ok". Why? Even if there is physically nothing connected to this port.

Sorry about the missing part -- glad you were able to figure it out.  For anyone reading along without LV 8.0 or higher, the
missing item was the property ArmStart.TriggerType = Digital Edge.  That's the one that really enables the triggering.
