EP-4502 BACnet Integration
Overview
Access It! Universal.NET 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.
