1.0 Introduction
This document provides information on installing the OpenBAS-NWK-ETH3 Ethernet
controller.
1.1 OpenBAS-NWK-ETH3 Ethernet Controller
Mircom’s OpenBAS-NWK-ETH3 is an Ethernet gateway and controller that can connect to a
single OpenBAS-HV-NX10 series controller to provide Web server and IP protocol capability. It
has 2 field bus connections that are factory set to RS-485. One can be changed to RS-232
with accessories. It has a real time clock and calendar, programming logic controller and
scheduler to operate as a building controller.
1.2 Features
The OpenBAS-NWK-ETH3 Ethernet controller integrates into Mircom’s unified platform for
automating HVAC and mechanical rooms as well as incorporating energy management
features and lighting control to offer building owners and managers a seamless operation with
the following features:
• Modular design to cover any small, medium or large project.
• Industry standard field bus protocols to integrate into any existing BAS system such as
BACnet, Modbus, N2-Open, and ASCII.
• Advanced Networking to integrate into IP networks and use the most advanced features
and protocols such as distributed computing, USB and Cloud storage, HTML5,
JavaScript, XML, Ajax, SMS, and GSM.
• Universal inputs to connect any industry standard sensors.
• Modular add-ons for every Building Automation System solution.
• The OpenBAS software which provides owners and managers a single solution for
managing all their building’s automation needs.
Caution: Consult this document to learn about potential hazards. Hazards are
marked on the controller with the symbol on the left.
