I am trying to count TTL Pulses using Digital I/O ports on PCI-6703. I cannot get the reference timer. Any suggestions?

Hello gnareshp,
I recently encountered the same problem as you and produced the attached VI to generate a reference to the internal counter. Just drag the VI into your block diagram and via the use of a Task Property Node, read the Devices and Channels properties of the Counter task and use them as inputs to the Counter Reference Generator VI. You can then wire the output of this VI to the input of a task sample clock to drive both tasks from the counter's frequency.
The way it works is by building a system-recognisable reference to the Counter through string concatenation of the Counter's task properties and
references to the internal structure of a Sample Clock.
This reference can be really useful for retriggering certain typically untriggerable proceses!
