Connection between Arduino Uno and NI USB 6008 DAQ

I am trying to figure out how to send a signal between the Arduino Uno to the USB 6008 DAQ. The USB 6008 DAQ can read TTL,LVTTL, and CMOS digital signals. If I read the datasheet correct the Arduino can output a TTL signal. My question is what code do I need to enter into the Arduino for it to ouput a signal to the 6008 DAQ. Thanks any help is appreciated as I am fairly new to Arduino.

What is the point of this?

The USB 6008 DAQ is a very capable DAQ device.

What do you mean?
