78M6618 PDU1 Firmware Quick Start Guide
UG_6618_122
2 Getting Started with the EVK
This section describes the necessary steps to get the pre-built application up and running. Note that some
of the steps are only required once when the setup is installed for the first time.
2.1 USB Driver Installation
The Evaluation Kit includes an isolated USB interface for serial communications with a PC. The FTDI
USB controller IC FT232R performs the USB functions. Refer to the 78M6618 PDU1 Evaluation Board
User Manual for information about USB Driver installation.
2.2 Connecting the Evaluation Board to the PC
DO NOT APPLY AC POWER TO THE BOARD YET!
Connect the 78M6618 PDU1 Evaluation Board to a USB port of the PC using the provided USB cable.
The USB controller is powered through this connection. If installed for the first time, the PC will prompt
you to install a USB-COM driver. Refer to the 78M6618 PDU1 Evaluation Board User Manual for more
information.
2.3 Getting Ready to Measure AC Energy
Refer to the included Safety Precautions application note and 78M6618 PDU1 Evaluation
Board User Manual for detailed instructions if not already familiar with energy measurement,
and for trouble shooting tips. Otherwise, connect AC source and loads to evaluation board
along with external 12VDC power supply.
2.4 Read Energy Measurement Data
The GUI application is now ready to be used to read energy measurement data and verify that the
hardware and software work properly. Refer to the 78M6618 PDU1 Demo Application User Guide for
more information.
2.5 Calibration
All evaluation kits come pre-calibrated to a precision source.
Note: Calibration requires connection of a reference power supply and a reference load that are more
accurate than the desired calibrated accuracy. For more information, refer to the 78M661x Calibration
Procedure.
