1 Introduction
The Teridian™ 78M6613 Evaluation Board is an electrical measurement unit for performing
measurements of up to two single-phase AC loads. It incorporates the 78M6613 power- and energy-
measurement IC and connects to a PC through a USB cable such as the one provided in the demo kit.
The Evaluation Board demonstrates the capability of the 78M6613 energy-meter controller chip for
measurement accuracy and overall system use.
The board is preprogrammed with Firmware Demo Code (file name
6613_OMU_S2+2_URT_V1_1x.hex) in the flash memory of the
78M6613 IC that allows evaluation of the IC’s capabilities.
The 78M6613 energy-measurement data and status is read back over
the serial UART interface using a text-based command line interface
(CLI) command set. Easy manual operation is performed using
HyperTerminal. Refer to the applicable 6613_OMU_S2+2_URT_V1_1x
Firmware Description Document for invocation usage of the CLI
commands.
1.1 Package Contents

1.3 Safety and ESD Notes
EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT!
Standard ESD precautions must be taken when handling electronic equipment. The
78M6613 contains ESD protected interfaces.
Do not connect test equipment, ICE emulators or external development boards directly to the
78M6613 hardware. Damage to the 78M6613 and external equipment will occur due to the
78M6613’s “high side” reference topology. The 78M6613’s V3P3 (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
110-240 VAC 10 mA – 20A 46-64 Hz
1.4 Firmware Demo Code Introduction
The Firmware Demo Code provides the following features:
•Basic energy measurement data such as Watts, Volts, current, VAR, VA, phase angle, power factor,
accumulated energy, frequency, date/time, and various alarm statuses.
•Control of alarm thresholds, calibration coefficients, temperature compensation, etc.
The following setup is used to facilitate performance evaluation between the user at the PC host and the
firmware code in the board:
•The CLI through HyperTerminal or comparable terminal emulator on a different operating system. For
information about the CLI, see the applicable Firmware Description Document.
The 78M6613 is shipped with Firmware Demo Code Revision 1.0 or later loaded in the 78M6613 chip and
included on the CD. The code revision can be verified by entering the command >i via the command line
interface. Firmware for the Demo Unit can be updated using either the Teridian TFP2 or an in-circuit
emulator such as the Signum Systems ADM51 (www.signum.com).
1.5 Testing the 78M6613 Evaluation Board Prior to Shipping
Before every 78M6613 Evaluation Board is shipped, the following procedures have been performed at the
factory:
•Full Calibration – Precise energy source equipment is used to calibrate the current and voltage. The
temperature is also calibrated at the same time.
•Accuracy Test – This “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 driver for Windows presents a virtual COM
port for enabling serial communications. Control of the 78M6613 Evaluation Board can be managed using
a terminal emulation program. The FTDI Windows driver is a certified driver for Windows 2000 and
Windows XP.
1. Upon attaching the 78M6613 Evaluation 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 FT232R controller is powered from the USB cable and is active even
when no AC power is applied to the 78M6613 Evaluation Board.
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/FTDrivers.htm).

2.2 Confirm COM Port Mapping
1. Launch the Control Panel and click on the System icon.
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.
3. Take note of the COM port assignment for the USB Serial Port.
OMU1 COM Port:

2.3 Basic Connection Setup
Figure 1 shows the basic connections of the 78M6613 Evaluation Board for use with external equipment.
The 78M6613 Evaluation Board is powered through the USB cable. This same USB cable provides the
communications link between the host PC and the 78M6613 Evaluation Board.
The 78M6613 Evaluation Board accepts 120 VAC and 230 VAC (nominal) up to 300 VAC (max).
Figure 1: 78M6613 Evaluation Board Connections
Attach an AC source to J3 (Neutral) and J6 (Line). Attach the AC load to J4 (Neutral) and J8 (Line).
Note: The hardware and embedded firmware are capable of measuring two outlets or AC loads. For more
information, contact Maxim application support.

2.4 Verify Serial Connection to the PC
After connecting the USB cable from the 78M6613 Evaluation Board to the host PC, start the
HyperTerminal application (or another suitable communication program) and create a session using the
communication parameters shown in Table 1.

Port speed (baud) 38400
Data bits 8

HyperTerminal can be found in Windows by selecting Start All Programs Accessories 
Communications HyperTerminal. The connection parameters are configured by selecting File 
Properties. The New Connection Properties menu appears.
Select the appropriate COM port and click Configure. The COMn Properties menu appears.
Select
COM Port

Note that port parameters can only be adjusted when the connection is not active. It may be necessary to
click the Disconnect Button to disconnect the port.
FTDI COM Port Trouble-Shooting
CLI measurement can be displayed in two different formats: decimal or hex. Both formats are returned as
ASCII character strings. The following figure uses CLI commands to return the same data presented in
the Auto-Reporting mode.
Refer to the applicable Firmware Description Document for a complete description of available CLI
commands and their invocation usage.
The 6613_OMU_S2+2_URT_V1_1x.hex is compatible with the 78M6612 OMU GUI. Refer to the
OMU1-S-WW Demo Unit User Manual for installation and operation instructions applicable to the OMU
GUI.
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. Refer to Section 2.2 for access to the Device Manager. If
a Ball Point device exists, delete it and unplug and replug the evaluation board’s USB cable.
Use “?” for Decimal format
Use “$” for Hex format
Disconnect

2.5 In-Circuit Emulator (ICE) Adaptor
The 78M6613 firmware (stored in internal flash memory) can be updated to accommodate program
enhancements. Use the Signum ADM51 or the Teridian TFP-2 to download new firmware to the
78M6613. The supplied ICE Adaptor is required to interface the flat ribbon cable (provided with the
ADM51 or TFP-2) to the 78M6613 Evaluation Board.
Figure 3: ICE Adaptor
Figure 4 shows how to attach the ICE Adaptor to the 78M6613 Evaluation Board. Please make note of
the orientation of the ICE Adaptor as to how it attaches to the 78M6613 Evaluation Board (V3P3 ICE
Adaptor pin connects to the +V3P3 Evaluation Board pin).
Figure 4: Attaching the ICE Adaptor
Disconnect the 78M6613 Evaluation Board from live AC voltages before connecting the
ADM51 or TFP-2. An Earth ground disparity and high AC voltages are present on the
78M6613 Evaluation Board when it is connected to the AC outlet. Equipment damage
to the 78M6613, ADM51/TFP-2 and attached PC may occur when live AC voltages are
present on the 78M6613 Evaluation Board. Refer to the 78M6613 Safety Precautions
Applications Note for additional information.
It is recommended to always use the supplied flat ribbon cable. Do not use discrete wires in place of the
flat ribbon. Poor signal integrity will cause flash memory programming errors. Additional adaptors and flat
ribbon cables can be ordered through Maxim.
Power to the 78M6613 is provided via the USB cable. Attach the USB cable during programming.
