3.3 BMS Network Settings: Selecting Stored Configurations, Setting the MAC
Address, Device Instance and Baud Rate
3.3.1 Selecting Configuration Files for Devices: “S” Bank DIP Switches S0 – S3
The S bank of DIP switches (S0-S3) are used to select and load a configuration file from a group of
pretested/preloaded configuration files which are stored in the ProtoNode FPC-N34 and the ProtoNode
FPC-N35 (LonWorks).
NOTE: When setting DIP switches, ensure that power to the board is OFF.
3.3.1.1 FPC-N34 DIP Switch Settings
For most BACnet and Modbus TCP/IP profiles, all small ProtoCessor DIP Switches (A1-A8) must be set to
“off”. This is the default position when the ProtoNode is shipped so check the profile chart on the next
page before taking steps to manipulate the ProtoCessor DIP Switches.
NOTE: The lid on top of the ProtoNode must be removed to select the small ProtoCessor DIP
switches (A1-A8). To remove, pull on the lid while holding onto the 6 pin Phoenix connector.
Do not hold the wall mount tabs as these are designed to break off if not required.
• To select configurations using the ProtoCessor DIP Switches, open the ProtoNode and find the
DIP switches on the small ProtoCessor module that sits on top of the ProtoCarrier (Figure 5).
o The ProtoCessor A1 DIP switch is the lowest of the ProtoCessor DIP switches with A8 at the
top, as oriented in Figure 5.
NOTE: The ProtoCessor A2-A8 DIP switches are disabled for this configuration.

3.3.2 BACnet MS/TP (FPC-N34): Setting the MAC Address for BMS Network
• Set the BACnet MS/TP MAC Address of the ProtoNode to a value between 1 to 127 (MAC
Master Addresses); this is so that the BMS front end can find the ProtoNode via BACnet
Auto-Discovery.
NOTE: Never set a BACnet MS/TP MAC Address from 128 to 255. Addresses from 128 to 255 are
Slave Addresses and cannot be discovered by BMS front ends that support Auto-Discovery of
BACnet MS/TP devices.
• Set DIP switches A0 – A7 to assign MAC Address for BACnet MS/TP for the ProtoNode
FPC-N34.
• Refer to Appendix C.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.

3.3.3 BACnet (FPC-N34): Setting the Device Instance
• The A Bank of DIP switches are used for two purposes:
o For BACnet MS/TP, they are used to set the BACnet MS/TP MAC address (Section 3.3.2)
o For both BACnet MS/TP and BACnet/IP, they are also used to determine the BACnet Device
Instance values
• The BACnet Device Instance can range from 1 to 4,194,303.
• The BACnet device instance is calculated by taking the Node_Offset (default is 50,000) found in
Web Configurator (Section 5.2) and adding it to the value of the A Bank DIP switches.
• The formula for calculating the Device Instance is:
Device Instance = Node_Offset + A Bank DIP switch value
For example, if:
o Default Node_Offset value = 50,000
o A Bank DIP switch value = 11
Then the Device Instance value for the device is:
o Device Instance = 50,011
3.3.4 Metasys N2 or Modbus TCP/IP (FPC-N34): Setting the Node-ID
• Set DIP switches A0 – A7 to assign a Node-ID for Metasys N2 or Modbus TCP/IP to the ProtoNode.
• Node-ID’s range from 1-255. Refer to Appendix C.1 for the full range of addresses for setting
Node-ID.
Lochinvar ProtoNode Start-up Guide
Page 13 of 48
3.3.5 BACnet MS/TP (FPC-N34): Setting the Serial Baud Rate for BMS Network
• DIP switches B0 – B3 are 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 (FPC-N35 LonWorks).

4.2.1 Biasing the Modbus RS-485 Device Network
• An RS-485 network with more than one device needs to have biasing to ensure proper
communication. The biasing only needs to be done on one device.
• The ProtoNode has 510 ohm resistors that can be used to set the biasing. The ProtoNode’s default
positions from the factory for the Biasing jumpers are OFF.
• The OFF position is when the 2 RED biasing jumpers straddle the 4 pins closest to the outside of
the board of the ProtoNode. (Figure 11)
• Only turn biasing ON:
o IF the BMS cannot see more than one device connected to the ProtoNode
o AND all the settings (Modbus COM settings, wiring, and DIP switches) have been
checked.
• To turn biasing ON, move the 2 RED biasing jumpers to straddle the 4 pins closest to the inside of
the board of the ProtoNode.

4.2.2 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.
o On 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).

4.2.3 Lochinvar Low Voltage Modbus RTU Wiring to the ProtoNode (Armor,
SYNC/Armor X2, Knight/Knight XL, Crest, Copper-Fin II and FTXL)
• On the Lochinvar’s Modbus terminal strip, connect Pin A (RS-485+) to B+ (RS-485+) on the
ProtoNode’s 6 Pin Phoenix connector.
• On the Lochinvar’s Modbus terminal strip, connect Pin B (RS-485-) to A- (RS-485-) on the
ProtoNode’s 6 pin Phoenix connector.
• The Shield Pin on the terminal strip (which is Ground) does not need to be grounded to the
ProtoNode.
