Section 9: System Integration and Networking
Topics in this section cover integrating the controllers into a building automation network. These are advanced reference topics
for control technicians and engineers.
The controllers can be installed as standalone controllers or they can be connected to a BACnet MS/TP network. The topics in this
section are reference material for control technicians or engineers who are planning, installing, and setting up controllers that are
connected to a network.
In addition to the information in this section, you will also need the following information.
• Detailed plans and drawings for the building automation system.
• Information about the facility LAN including routers, switches, and network firewalls.
• Sequences of operation for other BACnet devices that will monitor or interact with EZvav controllers.

Connecting to an MS/TP network
EZvav controllers are BACnet MS/TP compliant controllers. Connect them only to a BACnet MS/TP network.
To enter the BACnet device instance, MAC address, and network baud, see the topic Setting up network communications on page 42
