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 energymeasurement 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
The 78M6613 Evaluation Board Demo Kit includes:
• 78M6613 Evaluation Board
• USB Cable Assembly USB A-B 28/24 1.8M (Tyco/Amp 1487588-3)
• CD with documentation
1.2 System Requirements
The 78M6613 Evaluation Board requires use of a PC with the following features:
• PC (1 GHz, 1 GB) with Microsoft Windows XP®, Windows Vista®, or Windows 7 operating systems
equipped with USB port
• Minimum 1024 x 768 video display resolution

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%.
