EDWARDS – EST3 to BMS Communications Bridges – Model FSB-PC2 and FSB-PCLW
The EST3 Communication Bridges are ancillary devices that
provide protocol translation between EST3 serial data and the
serial or Ethernet input of an external device controller. Signal
flow is typically one way — from the EST3 network to the building
automation system.
Two communication bridges are available for use with EST3
systems. Each comes complete with the EST3 driver necessary to
communicate over a single supported protocol.
The FSB-PC2 is a multi-protocol bridge that converts the EST3
External Communications Protocol (ECP) to any one of several
supported protocols including Modbus RTU, BACnet MSTP and
Metasys N2. It operates over RS-232 or RS-485 serial communications or Ethernet (10/100 Base-T).
The FSB-PCLW is a single-protocol bridge that converts the
EST3 External Communications Protocol (ECP) to Lon Works only.
