GF-122 AERCO XPC GATEWAY
3
Foreword
The AERCO XPC (Extended Protocol Converter) allows a Building Automation Systems (BAS) or
Energy Management System (EMS) utilizing BACnet, Johnson N2 or LonWorks protocol to
communicate with AERCO boilers and water heaters which utilize Modbus.
The AERCO XPC Gateway can monitor and control up to 300 points. Each XPC is individually
programmed to your specific needs.
The information provided in this document is divided into an Introduction followed by three (3) parts:
• Introduction – An introduction to and general description of the AERCO XPC Gateway.
• Part
I - Provides a top-level description of the AERCO XPC Gateway features and capabilities.
It also includes detailed set-up and programming instructions to interface the XPC
Gateway to the AERCO equipment to be monitored or controlled on the network.
• Part
II - Provides the set-up and programming instructions to interface the AERCO XPC
Gateway to a Building Automation System (BAS) or Energy Management System (EMS)
which utilizes BACnet, Johnson N2 or LonWorks protocol.
• Part
III – Provides the protocol mapping points for the standard configurations which can be
monitored or controlled.
