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.
1.1 Package Contents

•
•
•
•
•
OMU1-S-RF module
USB A/B cable
USB-OPTO Daughter Board
UART-ISO Daughter Board
CD with Software and Documentation
1.2 System Requirements
The OMU1-S-RF GUI requires use of a PC with the following features:

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:
•
•
6
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%.

2 Installation
2.1 USB Driver Installation
This evaluation kit includes an optically isolated USB adaptor board for serial communications with a PC.
The FTDI USB controller IC FT232RL performs the USB functions. The FTDI Windows driver presents a
virtual COM port for enabling serial communications. Control of the OMU1-S-RF module can be
managed using either a terminal emulation program or using the supplied Windows Dashboard GUI. The
FTDI Windows driver is a certified driver for Windows 2000 and XP.
1. Upon attaching the OMU1-S-RF module 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 FT232RL controller is powered from the USB cable and is active even when no AC power is
applied to the OMU1-S-RF.
Notes: 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, please check FTDI’s website at
(http://www.ftdichip.com/FTDrivers.htm).

2.2 Basic Connection Setup
Figure 1 shows the basic connections of the OMU1-S-RF with the external equipment. The OMU1-S-RF
is powered by an internal switch-mode power supply (SMPS) module and is not powered through the
USB cable. The USB connection only provides the communications link between the host PC and the
OMU1-S-RF.

2.2.1 Attaching the USB-OPTO Daughter Board to the OMU1-S-RF
Attach the USB-OPTO daughter board to the OMU1-S-RF for use with the supplied GUI. This hardware
interface provides an easy way to explore the 78M6612 firmware features. The USB daughter board
incorporates signal isolators to protect the connected PC.
Attach the USB-OPTO daughter board to the OMU1-S-RF’s UART cable as shown. Take note of the
cable’s Red wire (+V) with regards to the daughter board’s connector pin assignments.
Do not attach external equipment to the OMU1-S-RF when using the USB-OPTO.
If it is necessary to attach test equipment, contact Teridian for instructions.

2.2.2 Attaching the UART-ISO Daughter Board to the OMU1-S-RF
Attach the UART-ISO daughter board to the OMU1-S-RF for use with external development boards.
External development boards are customer-supplied hardware incorporating their communications
module and debug interfaces. Their debug interfaces are typically RS-232 or USB cables with direct
connections to a PC. The daughter board incorporates signal isolators to protect the external
development board hardware and its attached PC.
Attach the UART-ISO daughter board to the OMU1-S-RF’s UART cable as shown. Take note of the
cable’s Red wire (+V) with regards to the daughter board’s connector pin assignments.
The UART-ISO daughter board does not supply power to the attached external development board. The
female connector J2 is provided for attaching the external development board. The J2 pin assignments
are as follows:
Pin 1
Pin 2
Pin 3
Pin 4
+3.3V or +5V (input, required to power signal isolator)
TX (78M6612 output, Vout dependent on voltage at pin 1)
RX (78M6612 input, Vin threshold dependent on voltage at pin 1)
GND
The UART-ISO daughter board does not support 1.8V signal levels.
Do not attach external equipment to the OMU1-S-RF when using the UART-ISO.
If it is necessary to attach test equipment, contact Teridian for instructions.

A fully isolated external communications board (i.e. Wireless or PLC module) may be attached to the
OMU1-S-RF’s UART cable without using the UART-ISO daughter board. The OMU1-S-RF UART cable
supplies 100 ma max at +3.3 V.
The OMU1-S-RF UART cable pin assignments are as follows:
Pin 1
