Ni 9401 geberate a TTL pulse

[zhiqin]

I'm a beginner with labview and DAQ device. now I have cDAQ 9172 and Ni9401, i want to use ni 9401 to output a TTL pulse to control the injector driver . I quite confused that  what kind of inputs should i give that it can generate this digital output. I also want to have some kind of graph that shows my output is what i want. Can anybody give some hint about it?

Thank u guys first

What is your development environment?

If its LabVIEW, just use the Example Finder (Help menu) to search for "pulse" and you will find several DAQmx examples which you should be able to run with your hardware.
