1 Introduction

The Teridian Outlet Measurement Unit, Model OMU1-S-RF, is a low-cost power monitor utilizing the Teridian 78M6612 SOC. The Teridian 78M6612 monitors the AC line voltages and load current, and controls switching of an internal load relay. The embedded firmware calculates the RMS line voltage and RMS load current, watts, VA, VAR and power factor. The real time data is transmitted to a PC for display in a Windows based Graphical User Interface (GUI). The 78M6612’s UART interface is used as the communications link to a customer supplied RF module for the OMU1-S-RF. The OMU1-S-RF evaluation kit is intended to be used for development and integration of a separate communications interface. Included with the OMU1-S-RF is a pair of isolated daughter boards and a Windows based Graphical User Interface (GUI) for simplified access to the following measurement data and controls:

  • Power, current, voltage and power factor indicator dials
  • Adjustable display scales
  • Minimum and peak parameter tracking
  • Selectable strip chart display format
  • Narrow-band versus Wide-band measurement
  • Selectable sample size averaging
  • Accumulated energy usage and expense tracking
  • Line frequency
  • Alarm indicators
  • Programmable Alarm thresholds
  • Internal load relay (16A) control
  • Data log to file Alternatively, the user can directly query the device with the command set using HyperTerminal and the provided 6612_OMU_S2_URT_V1_13 Firmware Description Document.

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 OMU1-S-RF contains ESD protected interfaces. 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:

  • 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. 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 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. 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 ( http://www.signum.com/Signum.htm). 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

1.5 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:

  • 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%.
