I want to use a counter in my DAQ card to count TTL pulses and I want this counter is started by a external trigger.
I run the example progrem 'counter-count edges.vi' provided by Labview and choose the tag of "Digital Arm Start". There is a error message which shows "Specified property is not supported by the device or is not applicabel to the task".
My DAQ card is PCI 6733 and my labview version is 2012 service pack1.
Does that mean the counter in my DAQ card cannot be triggered by external pulse? How can I do if I want to start a counter by external trigger? Thanks
