TROUBLESHOOTING
The CMD-12DP512 board is fully tested and operational before shipping. If it fails to function
properly, inspect the board for obvious physical damage first. Review the GETTING STARTED
section of this manual and verify the option settings and connections. See the Tips and
Suggestions sections following for more information.
