Quick Start Guide
1. Record the information about the unit. (Section 3.1)
2. Set the device’s COM settings and Node-ID for each of the devices that are to connect to the
ProtoNode. (Section 3.3)
3. FPC-N34: Select the protocol configuration on the S Bank DIP switches. (Section 3.4)
4. BACnet MS/TP (FPC-N34): Set the MAC Address on the A Bank DIP switches. (Section 3.5.1)
5. BACnet MS/TP (FPC-N34): Set the baud rate of the BACnet MS/TP field protocol on the B Bank DIP
switches. (Section 3.5.2)
6. Connect the ProtoNode 6 pin RS-485 connector to the RS-485 network that is connected to each of
the devices. (Section 4.2)
7. Connect the ProtoNode FPC-N34 3 pin RS-485 port to the field protocol cabling, (Section 4.3)
or connect the ProtoNode FPC-N35 2 pin LonWorks port to the field protocol cabling. (Section 4.4)
8. Connect power to the ProtoNode 6 pin connector. (Section 4.5)
9. Use a web browser to access the ProtoNode Web Configurator page to select the profiles of the
devices attached to the ProtoNode and input the Node-ID from each device. Once the devices are
selected, the ProtoNode automatically builds and loads the appropriate configuration. (Section 5)
10. 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 are necessary. (Section 5.4)
11. LonWorks (FPC-N35): The ProtoNode must be commissioned on the LonWorks Network. This needs
to be done by the LonWorks administrator using a LonWorks commissioning tool. (Section 8)

2 INTRODUCTION
2.1 ProtoNode Gateway
The ProtoNode is an external, high performance building automation multi-protocol gateway that is
preconfigured to automatically communicate between Thermal Solutions’ products (hereafter called
“device”) connected to the ProtoNode and automatically configures them for BACnet MS/TP, BACnet/IP,
Metasys®2 N2 by JCI, Modbus TCP/IP or LonWorks®3.
It is not necessary to download any configuration files to support the required applications. The
ProtoNode is pre-loaded with tested profiles/configurations for the supported devices.

3 SETUP FOR PROTONODE
3.1 Record Identification Data
Each ProtoNode has a unique part number located on the side or the back of the unit. This number
should be recorded, as it may be required for technical support. The numbers are as follows:
Model Part Number
ProtoNode FPC-N34 BACnet FPC-N34-0643
ProtoNode FPC-N35 LonWorks FPC-N35-0644
Figure 1: ProtoNode Part Numbers
•FPC-N34 units have the following 3 ports: BACnet RS-485 + Ethernet + Modbus RS-485
•FPC-N35 units have the following 3 ports: LonWorks + Ethernet + Modbus RS-485
3.2 Point Count Capacity and Registers per Device
The total number of registers presented by all the devices attached to the ProtoNode cannot
exceed:

3.3 Configuring Device Communications
3.3.1 Input COM Settings on All Devices Connected to the ProtoNode
•All of the connected serial devices MUST have the same baud rate, data bits, stop bits, and
parity settings as the ProtoNode.
•Figure 4 specifies the device serial port settings required to communicate with the ProtoNode.
Port Setting RWF40, RWF55, RM7800
Protocol Modbus RTU RS-485
Baud Rate 19,200
Parity None
Data Bits 8
Stop Bits 1
Figure 4: COM Settings
3.3.2 Set Node-ID for Each Device Attached to the ProtoNode
•Set Node-ID for each of the devices attached to ProtoNode. The Node-ID’s need to be uniquely
assigned between 1 and 255.
•Document the Node-ID assigned for each device. The Node-ID’s assigned are used for deriving
the Device Instance for BACnet/IP and BACnet MS/TP. (Section 3.5.2)
NOTE: The Metasys N2 and Modbus TCP/IP field protocol Node-IDs are automatically set to be the
same value as the Node-ID of the device.

3.4 Selecting the Desired Protocol Configuration
•ProtoNode FPC-N34 BACnet units use the “S” bank of DIP switches (S0 – S3) to select the
protocol configuration.
oSee the table in Figure 5 for the switch settings to select
oThe OFF position is when the DIP switches are set closest to the outside of the box
•ProtoNode FPC-N35 LonWorks units do not use the “S” bank DIP switches (S0 – S3) to select a
field protocol.
oOn ProtoNode FPC-N35 units, these switches are disabled; the field protocol is always

3.5 BMS Network Settings: MAC Address, Device Instance and Baud Rate
3.5.1 BACnet MS/TP (FPC-N34): Setting the MAC Address for BMS Network
•Only 1 MAC Address is set for ProtoNode regardless of how many devices are connected to
ProtoNode.
•Set the BACnet MS/TP MAC Address of the ProtoNode to a value between 1 to 127 (Master
MAC Address); this is so that the BMS front end can find ProtoNode via BACnet Auto-Discovery.
NOTE: Never set a BACnet MS/TP MAC Address of the ProtoNode to a value from 128 to 255.
Addresses from 128 to 255 are Slave Addresses and can not be discovered by BMS front
ends that support Auto-Discovery of BACnet MS/TP devices.
•Set “A” bank DIP switches A0 – A7 to assign a MAC Address to the ProtoNode for BACnet
MS/TP.
•Refer to Appendix D.1 for the complete range of MAC Addresses and DIP switch settings.
NOTE: When using Metasys N2 and Modbus TCP/IP, the A Bank of DIP switches are disabled and
not used. They should be set to OFF.

3.5.2 BACnet (FPC-N34): Calculating the Default Device Instance
•The Device Instance value is automatically generated using the following formula:
BACnet Device Instance = (Device Node ID) + (Default Node Offset)
NOTE: The default Node Offset is 50,000.
For example, if Device A has a Node ID of 1 and Device B has a Node ID of 2, then:
BACnet Device Instance A = (1) + (50000) = 50001
BACnet Device Instance B = (2) + (50000) = 50002
NOTE: The Node ID is set in Section 3.3.2.
•To reach a specific BACnet Device Instance result, refer to Section 6.
3.5.3 BACnet MS/TP (FPC-N34): Setting the Baud Rate for BMS Network
•DIP switches B0 – B3 can be used to set the field baud rate of the ProtoNode to match the baud
rate required by the BMS for BACnet MS/TP.
•The ProtoNode baud rate for Metasys N2 is set for 9600. DIP switches B0 – B3 are disabled for
Metasys N2 on ProtoNode FPC-N34.
•DIP switches B0 – B3 are disabled on ProtoNode FPC-N35 (LonWorks).

4.2.5 End of Line Termination Switch for the Modbus RS-485 Device Network
•On long RS-485 cabling runs, the RS-485 trunk must be properly terminated at each end.
•The ProtoNode has an End of Line (EOL) blue jumper. The default setting for this Blue EOL
switch is OFF with the jumper straddling the pins closest to the inside of the board of the
ProtoNode.
oOn short cabling runs the EOL switch does not to need to be turned ON
•If the ProtoNode is placed at one of the ends of the trunk, set the blue EOL jumper to the
ON position straddling the pins closest to the outside of the board of the ProtoNode.
•Always leave the single Red Jumper in the A position (default factory setting).
