The MAX5427 EV kit is fully assembled and tested. Follow
the steps below to verify board operation. Do not turn on
the power supply until all connections are completed:
1) Connect a cable from the computer’s parallel port
2) Adjust the variable power supply to 5V.
3) Ensure that the variable power supply is turned off.
4) Ensure that the fixed 11V power supply is turned
5) Connect the positive terminal of the variable power
6) Connect the ground return of the variable power
