ProtoNode Startup Guide
Quick Start Guide
1. Record the information about the unit. (Section 2.1)
2. Set the device’s Modbus RTU serial settings (i.e. baud rate, parity, stop bits) and Modbus Node-ID
for each of the devices that will be connected to ProtoNode FPC-N34 or FPC-N35. (Section 2.3)
3. ProtoNode FPC-N34 units: Select the Field Protocol on the S Bank Dip Switches. (Section 2.4.1)
4. Enable the ProtoNode “Auto Discovery” mode on Dip Switch Bank S. (Section 2.4.2)
5. BACnet MS/TP (FPC-N34): Set the MAC Address on DIP Switch Bank A. (Section 2.5.1)
6. BACnet MS/TP or BACnet/IP (FPC-N34): Set the BACnet Device Instance. (Section 2.5.2)
7. Metasys N2 or Modbus TCP/IP (FPC-N34): Set the Node-ID. (Section 2.5.3)
8. BACnet MS/TP (FPC-N34): Set the BAUD rate of the BACnet MS/TP Field Protocol on DIP Switch
Bank B. (Section 2.5.4)
9. Connect ProtoNode’s 6 pin RS-485 connector to the Modbus RS-485 network that is connected to
each of the devices. (Section 3.2)
10.Connect ProtoNode FPC-N34’s 3 pin RS-485 port to the Field Protocol cabling, (Section 3.3) or
connect ProtoNode FPC-N35’s 2 pin LonWorks port to the Field Protocol cabling. (Section 3.4)
11.Connect Power to ProtoNode’s 6 pin connector. (Section 3.5)
12.When power is applied it will take about 3 minutes for all the devices to be discovered, and the
configuration file to be built. Once Auto-Discovery is complete turn OFF the S3 DIP Switch to save
the configuration settings. (Section 3.5.1)
13.BACnet/IP or Modbus TCP/IP (FPC-N34): Use the ProtoNode’s embedded tool which is accessed
with a browser, referred to in this manual as the Web Configurator, to change the IP Address. No
changes to the configuration file are necessary. (Section 4)
14.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 7)

2.3 Configuring Device Communications
2.3.1 Set COM setting on all of the Devices connected to the ProtoNode
•Set up all devices on the same subnet as the ProtoNode.
•All of the serial devices connected to ProtoNode MUST have the same Baud Rate, Data
Bits, Stop Bits, and Parity settings.
•Figure 4 specifies the device serial port settings required to communicate with the ProtoNode.
•Set the Modbus COM settings on the devices now. When mixing devices, the selected baud
rates are required to match the slowest device (ENVI=9600). When there are no ENVI units
present, the baud rate could be set faster (LOVE end NURO support 19200 and 38400).
oThe ProtoNode’s default settings are 9600 / None / 8 /1
oAbility to change the ProtoNode’s Device COM settings are offered later in Section 2.5.1
•The Selected device COM settings need to be documented.

2.4.1 Selecting Desired Field Protocol
•ProtoNode FPC-N34 units use the “S” bank of DIP switches (S0 – S2) to select the Field
Protocol.
oSee the table in Figure 5 for the switch settings for the ProtoNode.
oThe OFF position is when the DIP switches are set closest to the outside of the box.
•ProtoNode FPC-N35 units do not use the “S” bank DIP switches (S0 – S2) to select a Field
Protocol.
oOn ProtoNode FPC-N35 units, these switches are disabled; the Field Protocol is always
LonWorks.

2.5 BMS Network Settings: MAC Address, Device Instance and Baud Rate
2.5.1 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 addresses 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 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 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.

ProtoNode Startup Guide
2.5.2 BACnet MS/TP and BACnet/IP (FPC-N34): Setting the Device Instance
•The BACnet Device Instances will be calculated by adding the Node_Offset (default value is
50,000) to the device’s Modbus Node ID (that was assigned in Section ).
•The BACnet Device Instance can range from 1 to 4,194,303.
For example:
If the following is true:
oNode_Offset value (default) = 50,000
oDevice 1 has a Modbus Node-ID of 1
oDevice 2 has a Modbus Node-ID of 22
oDevice 3 has a Modbus Node-ID of 33
And given that: Device Instance = Node_Offset + Modbus Node_ID
Then Device Instances are:
o
Device 1 =
50,000
+ 1 = 50,001
o
Device 2 =
50,000
+ 22 =
50,022
o
Device 3 =
50,000
+ 33 =
50,033
2.5.2.1 BACnet MS/TP or BACnet/IP: Assigning Specific Device Instances
•With the default Node_Offset value of 50,000 the Device Instances values generated will be
within the range of 50,001 to 50,127.
•The values allowed for a BACnet Device Instance can range from 1 to 4,194,303.
•To assign a specific Device Instance (or range), change the Node_Offset value.
•Methods for changing the Node_Offset value are provided in Section 5.
oThis step cannot be performed until after the unit is connected and powered.
2.5.3 Metasys N2 or Modbus TCP/IP (FPC-N34): Setting the Node-ID
•The Modbus RTU Node-ID’s assigned to the devices attached to the ProtoNode in Section will
be the Metasy N2 or Modbus TCP/IP Node-ID’s to the field protocols.
•Node-ID’s range from 1-255. Refer to Appendix C.1 for the full range of addresses for setting
Node-ID.
Page 13 of 50

ProtoNode Startup Guide
2.5.4 BACnet MS/TP (FPC-N34): Setting the Baud Rate for BMS Network
•“B” bank DIP switches B0 – B3 can be used to set the Field baud rate of the ProtoNode to match
the baud rate required by the Building Management System for BACnet MS/TP.
•The baud rate on ProtoNode for Metasys N2 is set for 9600. “B” bank DIP switches B0 – B3 are
disabled for Metasys N2 on ProtoNode FPC-N34.
•“B” bank DIP switches B0 – B3 are disabled on ProtoNode FPC-N35 (LonWorks).

ProtoNode Startup Guide
3.2.4 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.
•None of the ENVI’s support biasing. The ProtoNode is required to bias the RS-485 network.
•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 12)
•Only turn biasing ON:
oIF the BMS cannot see more than one device connected to the ProtoNode
oAND 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.
