78M6612 OMU1-S-RF Demo Unit User Manual
1.3 Safety and ESD Notes
Do not connect test equipment, ICE emulators or external development boards directly to the
OMU-RF hardware. Damage to the OMU1-S-RF and external equipment will occur due to the
78M6612’s “high side” reference topology. The 78M6612’s V3P3 (i.e. “high side”) is connected
directly to Neutral (Earth Ground) creating a ground reference disparity with any properly
grounded external equipment.
Always use the provided UART-ISO daughter board for connecting external development boards.
Contact Teridian for instructions on connecting other types of test equipment.
1.4 Firmware Demo Code Introduction
The Firmware Demo Code provides the following features:
•
•
There are two means to facilitate performance evaluation between the user at the PC host and the
firmware code in the OMU1-S-RF Demo Unit:
•
•
The OMU1-S-RF Demo Unit is shipped with Demo Code Revision 1.13 or later loaded in the 78M6612
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 TFP1 or
an in-circuit emulator such as the Signum Systems™ ADM-51 (
The board components and firmware settings are designed to operate with the following nominal AC
electrical ranges:
Voltage
110-240 VAC
1.5 Testing the Demo Unit Prior to Shipping
Before every OMU1-S-RF Demo Unit is shipped, the following procedures have been performed at the
factory:
•
•
6
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 Graphical User Interface (GUI). This document describes the installation and use of the
Windows based GUI.
The Command Line Interface (CLI) via HyperTerminal or comparable terminal emulator on a different
operating system. For information about the CLI, see the 6612_OMU_S2_URT_V1_13 Firmware
Description Document.
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 measurement accuracy is within +/-0.5%.
EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT!
Standard ESD precautions must be taken when handling electronic equipment. The
OMU1-S-RF contains ESD protected interfaces.
Current
10 mA – 20A
Line Frequency
46-64 Hz
