Quick Start Guide
1. Record the information about the unit. (Section 3.1)
2. Set the device’s COM settings and Node-ID for the device that is to connect to the ProtoNode. (Section
3.2)
3. Select a stored configuration then set the field protocol’s MAC Address, Node-ID and baud rate.
(Section 3.3)
4. Connect the ProtoNode’s 6 pin RS-485 connector to the RS-485 network that is connected to the
device. (Section 4.2)
5. Connect the ProtoNode FPC-N34 3 pin RS-485 port to the field protocol cabling, (Section 4.2.3)
or connect the ProtoNode FPC-N35 2 pin LonWorks port to the field protocol cabling. (Section 4.4)
6. Connect power to the ProtoNode’s 6 pin connector. (Section 4.5)
7. Ethernet network (FPC-N34): Use a web browser to access the ProtoNode Web Configurator page to
change the IP Address. No changes to the configuration file are necessary. (Section 5)
8. LonWorks (FPC-N35): The ProtoNode must be commissioned on the LonWorks network. This must be
done by the LonWorks administrator using a LonWorks commissioning tool. (Section 7)
