chazimusmaximus,
For your specific DAQCard AI-16XE-50, the only output you can perform is digital output since there are no analog output lines on this board. Digital ouptut with NI-DAQ 7.0 will work with LabVIEW 6.1, but you can only use the Traditional DAQ VIs. Windows 2000 and the CB-68LP are both fine in this combination.
For example programs, simply launch LabVIEW 6.1 and go to Help >> Find Examples. Then follow the path Hardware Input and Output >> DAQ >> Digital Input and Output >> E-series to choose the example that works best for you.
Have a great day.
