1. BACnet Ethernet Description

The BACnet Ethernet driver allows the FieldServer to transfer data to and from devices over
Ethernet using BACnet Ethernet protocol. The FieldServer can emulate either a Server or
Client.

The information that follows describes how to expand upon the factory defaults provided in the
configuration files included with the FieldServer.
