1.1 - ProtoNode gateway
ProtoNode is an external, high performance Building Automation multi-protocol gateway that is pre-configured to automatically
communicate between any of Big
Ass
Fans’ products (hereafter called “device”) to various building automation protocols. These
protocols include BACnet
®1
MS/TP, BACnet/IP, Metasys
®2
N2 by JCI, and Modbus TCP. It is not necessary to download any
configuration files to support the required applications.
The ProtoNode has been designed to simultaneously support both known RS-485 and Ethernet devices connected to the ProtoNode.
The ProtoNode has all of the pretest Profiles/Configurations of all the devices stored inside itself. Two (2) methods of configuration are
used to dynamically set the devices up for the various protocols:
•
RS-485 devices connected to the ProtoNode are automatically discovered on power up. The ProtoNode performs an Auto-Discovery
of known profiles or devices connected on the RS-485 network.
•
Ethernet known devices connected to the ProtoNode cannot be Auto-Discovered. If you want to add known Ethernet devices, you
must run the ProtoNode’s Web Configurator. The Web Configurator will show all the stored profiles/devices that are inside the
ProtoNode. It will show all the RS-485 devices that were discovered. You will select which Ethernet devices you want to connect
to the ProtoNode (Ethernet and RS-485). You must select the device, Modbus Node-ID, and the IP Address if you are selecting
Ethernet devices. After you select all of the devices, the ProtoNode automatically builds and downloads the configuration for the
desired protocol.
