This document is a user manual for Simplifying System Integration TM OMU1-S-RF Demo Unit, describing the features and characteristics of the product.
The Teridian 78M6612 OMU1‑S‑RF Demo Unit is a low‑cost power monitor that measures AC line voltage and load current, calculates RMS values, power, and power factor, and provides data to a Windows‑based GUI. The unit includes isolated USB‑OPTO and UART‑ISO daughter boards, a load relay, and software for data logging and alarm configuration.
The manual guides users through driver installation, hardware connections, GUI operation, and provides schematics, bill of materials, and ordering information. Safety and ESD precautions are also detailed to protect both the unit and external equipment.
| Monitored parameters | RMS voltage, RMS current, watts, VA, VAR, power factor |
|---|---|
| Internal load relay rating | 16 A |
| USB controller IC | FT232RL |
It is powered by an internal switch‑mode power supply; the USB connection supplies only communication signals and does not provide power to the unit.
Install the FTDI driver from the CD; it creates a virtual COM port for serial communication with the unit. Use the FTDI driver utilities if needed.
Connect via the command‑line interface and enter the command ">i"; the unit will display the current firmware revision.
