Introduction
Overview
This document describes best practices, specifications, wiring rules, and application information to implement robust and
reliable communications networks.
About the nLight ECLYPSE Controller
The nLight ECLYPSE Controller is a modular and scalable platform that is used to control a wide range of HVAC applica-
tions. It uses IP protocol to communicate on wired Ethernet networks and Wi-Fi to communication on wireless networks.
For this document, the nLight ECLYPSE will also be referred to as just ECLYPSE.
This user guide also explains how to connect to the ECLYPSE controller's configuration interfaces.
About the IP Protocol Suite
Acuity Controls' nLight ECLYPSE controllers use a widely used IP protocol to communicate with each other and with other
applications for control and supervision. What is commonly referred to as IP is actually a multilayered protocol suite that re-
liably transmits data over the public Internet and privately firewalled-off intranets. As integral part of our interconnected
world, this protocol is used by applications such as the World Wide Web, email, File Transfer Protocol (FTP), datashares,
and so on.
ECLYPSE controllers are able to work across geographic boundaries as a unified entity for control and administration pur-
poses.
About BACnet®
The BACnet
®
ANSI/ASHRAE™ Standard 135-2008 specifies a number of Local Area Network (LAN) transport types. Acu-
ity Controls' controllers support both BACnet/IP and BACnet Master-Slave/Token-Passing (MS/TP) communications data
bus (based on the EIA‑485 medium) as a local network for inter-networking of supervisory controllers and field controllers.
About This User Guide
Purpose of the User Guide
This user guide does not provide and does not intend to provide instructions for safe wiring practices. It is the user's re-
sponsibility to adhere to the safety codes, safe wiring guidelines, and safe working practices to conform to the rules and
regulations in effect in the job site jurisdiction. This user guide does not intend to provide all the information and knowledge
of an experienced HVAC technician or engineer.
This user guide shows you how to integrate ECLYPSE controllers into your IP network environment while enforcing stan-
dard network security practices.
