OMU1-S-WW Demo Unit User Manual
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 Demo Unit:
•
•
The OMU1 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 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%.
Current
10 mA – 20A
Line Frequency
46-64 Hz
