ACE100 QUICK START:
Running the ADC180:
1) Connect the power supply inputs to the ACE100.
1) If the continuous operating mode is selected,
2) Connect the DB9 serial cable to the COM1
connector on your PC.

7) Double Click on the ACE1xx_Eval.exe file to start
8) AutoZero the converter to remove any offset drift.
