EP-4502 BACnet Integration


Overview

Access It! Universal.NET version 5.2 allows for BACnet communciation between a Mercury-Security EP-4502 and a standard BACnet client. The EP-4502 controller will act as a B-ASC type BACnet Server, exposing up to 64 user configurable resources to a BACnet network.

In order to use the BACNet integration, the communication between EP-4502 and server must be encrypted and using DHCP.
