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(R)-based graphical user interface (GUI) communicates with the device over the serial UART interface for simplified access to measurement data and controls. 1.1 Ordering Information PART 78M6610+PSU/EV#1 TYPE Evaluation Kit #Denotes a RoHS-compliant device that may include lead that is exempt under the RoHS requirements. 1.2 Package Contents The following are included with the 78M6610+PSU Evaluation Kit: * * 78M6610+PSU Evaluation Boards (16/24-pin) Shunt Adaptor Board * * USB Cable Assembly USB A-B 28/24 1.8M (Tyco/Amp 1487588-3) CD with Documentation, GUI Application, and USB Drivers 1.3 System Requirements In addition to an AC source and load for measuring, the 78M6610+PSU Evaluation Kit requires use of a PC with the following features: * * 1GHz processor and 1GB RAM Minimum 1024 x 768 video display resolution * * Available USB port (R) Microsoft Windows 7 or Windows XP Windows and Windows XP are registered trademarks of Microsoft Corp. 4 Rev 2 78M6610+PSU Evaluation Kit User Manual 120/240V Single Phase AC Source J1 78M6610+PSU Board J3 Shunt Adaptor Board 5V Voltage Divider J2 J4 DC/DC USB Controller Line Earth Gnd 78M6610 +PSU Current Shunt Neutral Isolation 3V3 Reg J11 USB Host PC Load Under Test Figure 1: 78M6610+PSU Evaluation Kit Application Diagram Rev 2 5 78M6610+PSU Evaluation Kit User Manual 1.4 Safety and ESD Notes EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT! Standard ESD precautions must be taken when handling electronic equipment. The 78M6610+PSU contains ESD protected 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 V3P3 supply rail (i.e., "high side") is connected directly to Neutral (Earth Ground) creating a ground reference disparity with any properly grounded external 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 Calibration - 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%. 6 Rev 2 78M6610+PSU Evaluation Kit User Manual 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 Evaluation Kit to the PC, the Found New Hardware Wizard should automatically launch and install the appropriate driver 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 installing this newer FTDI driver. Execute the ftdiClean.exe utility from the FTDI USB Driver 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. Rev 2 7 78M6610+PSU Evaluation Kit User Manual * 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. COM 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. 8 Rev 2 78M6610+PSU Evaluation Kit User Manual 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. Connector to Shunt Adaptor Board Figure 2: 78M6610+PSU Evaluation Board Figure 3: 78M6610+PSU Evaluation Kit Connections Rev 2 9 78M6610+PSU Evaluation Kit User Manual Attach an AC source 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 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. Follow the installation wizard instructions, or 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 communication with the evaluation kit, the firmware revision field will be green and populated with the revision of the 78M6610+PSU firmware. 3. Register Addresses: Rev 2 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. 13 78M6610+PSU Evaluation Kit User Manual 4 Schematics,
