What is the board?
If you simply installed the board, you probably need to install it's drivers.
MAX (Measurement & Automation Explorer) may not be able to identify the board until it is configured by the installation drivers. You should have received a CD or disquettes with the board. Otherwise, visit the board manufacturer website for the drivers. At the same time, check for any LabView drivers (and examples 😄 ) that they may have.
Many manufacturer's offer "Get Started" types of vi along with the LV drivers to get the automation going faster.
Also, if you let us know what the board is, we can provide more assistance.
Have fun during the weekend..
