Distech Controls ECL-VAV User Manual

6 Network Guide
Introduction
This document describes best practices, specifications, wiring rules, device termination, and
application information to implement robust and reliable communications networks.
About BACnet
®
The BACnet® ANSI/ASHRAE™ Standard 135-2008 specifies a number of Local Area Net-
work (LAN) transport types. Distech Controls' controllers use both BACnet IP and BACnet
Master-Slave/Token-Passing (MS/TP) communications data bus (based on EIA 485) as a
local network for internetworking of supervisory controllers and field controllers.
About LONWORKS
®
The LONWORKS standard ANSI/CEA-709.1-B specifies a number of Local Area Network (LAN)
transport types. Distech Controls' controllers use a twisted pair "free topology" communica-
tions data bus operating at 78 kbit/s as a local network for internetworking of supervisory con-
trollers and field controllers.
L
ONWORKS is one of several network types of the BACnet® ANSI/ASHRAE™ Standard; how-
ever, no Distech Controls' controllers are compatible with this network type except for an EC-
Net.
About Subnetworks
The Distech Controls' controllers and devices (BACnet and LONWORKS) use the subnetwork
data bus to support various expansion / extension modules such as the following: Allure
Series sensors, ECx-4XX I/O Extension Module, ECx-Light 4 / ECx-Light 4D / ECx-Light
4DALI, ECx-Blind 4 / ECx-Blind 4LV, and EC-Multi-Sensor series.
