1.4 Safety and ESD Notes
EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT!
Do not connect test equipment, ICE emulators or external development boards
directly to the MAX78630+PPM hardware. Damage to the MAX78630+PPM and
external equipment will occur due to the MAX78630+PPM’s “high side” reference
topology. The MAX78630+PPM’s V3P3 (i.e., “high side”) is connected directly to
Neutral (Earth Ground) or Line Voltage, 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
10-400V AC 10mA – 50A 46-64Hz
The maximum current is determined by the current transformer (CT) that is provided with t his EV kit:
CR Magnetics model no. CR8449-2500-N.
1.5 Testing the MAX78630+PPM EV Board Prior to Shipping
Before every EV kit is shipped, the board (and sensors) undergoes a single-load point calibration using precise
energy source equipment. The device temperature is also calibrated at the same time. Results printed out on
paper and included with the EV kit.
Note that the board is calibrated using the marked CTs included with the kit. Therefore, CT1 should be
connected to I1, CT2 to I2, and CT3 to I3.

Two sequential COM
2 Installation
2.1 USB Driver Installation
This EV kit includes an isolated USB interface for serial communications with a PC. The FTDI USB controller
IC FT2232 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 MAX78630+PPM EV board to the PC, the Found New Hardware Wizard automatically
launches and installs 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 FT2232
controller is powered from the USB cable and is active even when no AC power is applied to the
MAX78630+PPM EV kit.
Note: If an older FTDI driver has been previously installed, it is recommended to re m ove the older version
before installing this newer FTDI driver. Execute the ftdiClean.exe utility from the F T DI USB Driver and
Utilities subdirectory.
For FTDI driver support on other operating syst ems, refer to the FTDI website at www.ftdichip.com.
2.1.1 Confirm COM Port Mapping
• Launch the Control Panel and click on the System icon.
• 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 US B S eri al Port.
2.1.2 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 Install ation, see
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 Dev i ces” via the Device manager. See
for access to the Device Manager. If a Ball Point device exists, delete it and unplug and replug the EV kit’s
USB cable.
ports are associated
with the kit. Use the
second COM port
Port numbers may
differ on each PC.

2.2 Powering the EV Kit Board
The MAX78630+PPM EV board is normally powered through the USB port (J21).If power needs to be supplied
from a different source, a 5V DC can be applied to the connector J16; see
Table 16 for the pin assignment.
When the MAX78630+PPM EV board is powered through via USB, the same cable also provides the
communications link between the host PC and t he MAX78630+PPM EV board.
2.3 Basic Connection Setup
This section shows examples of basic connections between the MAX78630+PPM EV board and external
equipment. Additional connection examples can be seen in the MAX78630+PPM IC data sheet. Note that this
board does not directly support voltage transformers (VT) and provides a shun t resistor as alternative to the
current transformer on phase C.
The following examples are only a subset of all possible measurement configurations. Refer to the
MAX78630+PPM IC data sheet for configurations and system connection diagrams.
2.3.1 Wye-Connected or 3V Delta-Connected Three-Phase Systems
For Wye-connected systems, all three-phase (Line-to-Neutral) voltages are measured. The Neutral line is the
reference for all voltages (V3P3A). Jumper J11 must be in position 2-3 (3V Wye/Del ta). It is also possible to
directly measure all three voltages in a Delta configuration. In that case, the Neutral is not accessible and the
MAX78630+PPM EV board is at a virtual center potential.

2.3.3 Neutral Current Measurement Considerations
It is possible, in certain Wye configurations to measure the current in the neutral conductor via a shunt resistor,
therefore replacing the third phase current measurement. This function is enabled by setting jumper J15 to
position 2-3. The MAX78630+PPM EV board then connects the shunt voltage to input AIC of the MAX78630.
IC (J41) is not measured in this case.

3 Serial Interfaces Selection and Configuration
The MAX78630+PPM has integrated UART, SPI (Slave), and I2C (Slave) interfaces. Only one interface can be
active at a time and the selection is done at reset/ power-on.
The UART interface also supports RS-485/422. The MAX78M6630+PPM EV board includes an isolated RS485/422 transceiver.
Table 9 shows the settings of SW4 for the individual interface selection; the signal IFC0 and IFC1 are sampled
at reset and power-on.

3.1 UART Interface Settings
The MAX78M6630+PPM implements a serial communication protocol (SSI) that supports multipoint
communication. The device address (lower bits) is selected through the pins ADDR0 and ADDR1, as show n in
Table 10. The upper bits of the address are set through the register DEVADDR, as described in the IC data
sheet.

The EV board includes an isolated RS-485/422 transceiver. The MAX78630+PPM serial UART is connected to
the RS-485/422 transceiver when a mult i-drop RS-485/422 bus is available.

4 Graphical User Interface (GUI)
A graphical user interface (GUI) is included on the MAX78630+PPM EV kit CD to facilitate quick evaluation of
the MAX78630+PPM 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. Follow the installation wizard instructions, or download
Microsoft.NET Framework 4 from the Micro sof t web site prior to launching the GUI.
4.1 GUI Initialization
The GUI is self-explanatory when used with the MAX78630+PPM Data Sheet. The user, how ever, should note
the following about the EV kit hardware:
• Serial COM Port:
Following the installation instructions in Section 2, launch the G UI executable. Click the
Connection pull-down menu and select Connect.
The COM Port / Baud Rate box appears. Select the COM port assigned to the EV kit and
leave the baud rate set to 38400 (default). Click the Connect button.
4.1.1 SSI ID Tab
• SSI ID:
Click the SSI tab. Use the SSI ID number set by DIP switch 5 (1 and 2 are closed by default)
and click Set Target. Upon successful communication with the EV kit, a message appears in
the message box.
