1 Introduction
The 78M6610+PSU Evaluation Kit is a design example of a modular daughter card for integration into AC-DC
power-supply units. The kit demonstrates the capabilities and performance of 78M6610+PSU energy
measurement device in both the 16-pin and 24-pin packages.
The kit is connected to a PC through a USB cable that provides both power and
data communication to the board. A Windows®-based graphical user interface
(GUI) communicates with the device over the serial UART interface for
simplified access to measurement data and controls.

1.4 Safety and ESD Notes
EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT!
Standard ESD precautions must be taken when handlin g electronic equipment. The
78M6610+PSU contains ESD pro tected interfaces.
Do not connect test equipment or external development boards directly to the
78M6610+PSU hardware. Damage to the 78M6610+PSU and external equipment will
occur due to the 78M6610+PSU’s “high side” reference topology. The
78M6610+PSU’s V3 P3 supply rail (i.e., “high side”) is connected directly to Neutral
(Earth Ground) creating a ground reference disparity with any properly grounded
extern al equipment.
The board components and firmware settings are designed to operate with the following nominal AC electrical
ranges:
Voltage Current Line Frequency
10–240 VAC 10mA–20A 46–64Hz
1.5 Testing the 78M6610+PSU Boards Prior to Shipping
Before every 78M6610+PSU Kit is shipped, the following procedures have been performed at the factory:
• Full Cal ibr a t io n – Precise energy source equipment is used to calibrate the current, voltage, and ambient
temperature for both the 16-pin and 24-pin daughter cards
• Accuracy Test – A “bench” level test ensures the energy accuracy is within ±0.5%.

2 Installation
2.1 USB Driver Installation
This Evaluation Kit includes an isolated USB interface for serial communications with a PC. The FTDI USB
controller IC FT232R performs the USB functions. The FTDI Windows driver presents a virtual COM port for
enabling serial communications. The FTDI Windows driver is a certified driver for Windows XP and Windows 7.
Upon attaching the 78M6610+PSU Evalu ati on Kit to the PC, the Found New Hardware Wizard should
automat ical l y launch and in stall the appropriate driv er files . If your PC does not find the FTDI driver files on its
local hard disk drive, locate and reference the FTDI USB Driver and Utilities subdirectory on the CD. The
FT232R controller is powered from the USB cable and is active even when no AC power is applied to the
78M6610+PSU Evaluation Kit.
Note: If an older FTDI driver has been previously installed, it is recommended to remove the older version
before i nst alli ng t his ne wer FT DI driver. Execute the ftdiClean.exe utility from the FTD I USB Dri ver and
Utilities subdirectory.
For FTDI driver support on other operating systems, refer to FTDI’s website at www.ftdichip.com.
2.2 Confirm COM Port Mapping
• Launch the Control Panel and click on the System icon.
78M6610+PSU Evaluation Kit User Manual
8 Rev 2
• The System Properties screen appears. Click on the Hardware tab. Click on Device Manager. Under
Ports (COM & LPT), look for the USB Serial Port assignment.
• Take note of the COM port assignment for the USB Serial Port.
2.2.1 FTDI COM Port Trouble Shooting
If the FTDI device driver did not install properly, there would be no assigned COM port number for the FTDI
controller. Repeat the USB Driver Installation, see Section 2.1.
Microsoft Windows may associate a Ball Point device to the FTDI USB controller. When this occurs a FTDI
device COM port assignment is available via HyperTerminal but there is no communications data. Verify if a
Ball Point device has been added to the “Human Interface Devices” via the Device Manager. See Section 2.2
for access to the Device Manager. If a Ball Point device exists, delete it and unplug and replug the Evaluation
Kit’s USB cable.

2.3 Basic Connection Setup
Figure 1 shows the basic connections of the 78M6610+PSU Evaluation Kit for use with external equipment.
The shunt adaptor board consists of the host side components necessary for the evaluation environment that
would be replaced by the target system. This host board provides a USB serial UART controller, serial
interface DC-DC power isolator, a current shunt, and AC wiring terminals.
After connecting the USB cable to J11 and installing the USB drivers, one can plug the 78M6610+PSU
Evaluation Board into the Shunt Adaptor Board as shown below.

Attach an AC sourc e and AC load to the Shunt Adaptor Board as shown below. Connect J1 and J3 to an
external AC power source. Connect J2 and J4 to the load to be measured. The 78M6610+PSU Evaluation Kit
hardware is designed for 120 VAC and 230 VAC (nominal) up to 300 VAC (max).

3 Graphical User Inter f a c e (GUI)
A graphical user interface (GUI) is included on the 78M6610+PSU Ev alu ati on Kit CD to facilitate quick
evaluation of the 78M6610+PSU energy measurement device. The GUI requires Microsoft.NET Framework 4
on the PC for which the GUI is to execute on. Upon invoking the GUI executable file, an installation wizard may
appear if Microsoft.NET Framework 4 is not installed on the PC. Follo w the installat ion wi zard ins truc ti ons , o r
download Microsoft.NET Framework 4 from the Microsoft web site prior to launching the GUI.
3.1 GUI Initialization
The GUI is self-explanatory when used with the 78M6610+PSU Data Sheet. The user, however, should note
the following about the evaluation kit hardware:
1. Serial COM Port:
Following the installation instructions in Section 2, launch the GUI executable and click the
“Scan Ports” button to populate the drop-down menu with the available COM ports. Select the
COM port assigned to the evaluation kit and leave the baud rate set to 38400 (default)
2. SSI ID: Use SSI ID 2 for the 78M6610+PSU Evaluation Kit then click “Connect”. Upon successful
comm unic ation wit h the evaluation kit, the firmware revision field will be green and populated
with the revision of the 78M6610+PSU firmware.
3. Register Addresses:
Common measurement and configuration parameters have their own labeled cells. For direct
register read/writes, reference the byte-addressable registers in the data sheet for the
synchronous serial interface (SSI) protocol.
