Hi Alan_mfi,
I would recommend taking a look at our DAQmx help file for information regarding device pinouts and information about DAQmx tasks. After installing our DAQmx driver, this help file will be located in Start » All Programs » National Instruments » NI-DAQ. If you simply search for 6009 in the help file, you can find the exact device pinouts for the device. This should assist in making the proper connections from your motor drivers to your USB-6009. This information can also be found in the online manual found
here. I'm assuming you will be using the digital I/O lines on your 6009 to control the motor driver. Assuming this motor driver will accept the voltage / current specifications of the digital IO lines of the 6009, you should be able to control the output of these digital IO lines with a simple LabVIEW application. I would highly recommend starting with our examples. These examples can be found by going to Help » Find Examples in LabVIEW and navigating to Hardware Input and Output » DAQmx » Digital Generation section.
I hope this helps,
Paul C.
