NI PXI 6229 DAQ Card Digital Output High/Low Levels

[testdesign]

Hi everyone, I can't seem to find in the NI PXI 6229 DAQ spec what the Digital Output high voltage and low voltage is when I set a digital signal high and low.  What is the voltage when I set a Digital Output "HIGH" and what is the voltage when I set a Digital Output "LOW"?

Thanks!

See the digital I/O characteristics section of the specs. Typical ttl levels.
