LAARS ProtoNode Start-up Guide 3
Quick Start Guide
1. Record the information about the unit. (Section 2.1)
2. Check that the ProtoNode and customer device COM settings match. (Section 2.3)
3. Connect the ProtoNode 6 pin RS-485 connector to the RS-485 network that is connected to each of
the devices. (Section 3.2)
4. If using a serial field protocol:
Connect the ProtoNode FPC-N34 3 pin RS-485 port to the field protocol cabling, (Section 3.3)
or connect the ProtoNode FPC-N35 2 pin LonWorks port to the field protocol cabling. (Section 3.4)
5. Connect power to the ProtoNode 6 pin port. (Section 3.5)
6. Connect a PC to the ProtoNode via Ethernet cable. (Section 4)
7. Setup Web Server Security and login via web browser. (Section 5)
8. Use a web browser to access the ProtoNode Web Configurator page to select the profiles of the devices
attached to the ProtoNode and enter any necessary device information. Once the devices are selected,
the ProtoNode automatically builds and loads the appropriate configuration. (Section 8)
9. 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 9)

LAARS ProtoNode Start-up Guide 8
1 Introduction
1.1 ProtoNode Gateway
The ProtoNode is an external, high performance building automation multi-protocol gateway that is
preconfigured to automatically communicate between LAARS’devices (hereafter simply called “device”)
connected to the ProtoNode and automatically configures them for BACnet MS/TP, BACnet/IP, Modbus
TCP/IP or LonWorks®1.
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.
WARNING: Only use screws supplied by MSA Safety in the holes found on the back of the unit
when attaching the optional DIN rail bracket. Use of any other screws may damage the unit.

LAARS ProtoNode Start-up Guide 9
FPC-N35 Connectivity Diagram:
The ProtoNode can connect with the SMC Cloud. The SMC Cloud allows technicians, the OEM's support
team and MSA Safety's support team to remotely connect to the ProtoNode. The SMC Cloud provides the
following capabilities for any registered devices in the field:
•Remotely monitor and control devices.
•Collect device data and view it on the SMC Cloud Dashboard and the SMC Smart Phone App.
•Create user defined device notifications (alarm, trouble and warning) via SMS and/or Email.
•Generate diagnostic captures (as needed for troubleshooting) without going to the site.
For more information about the SMC Cloud, refer to the SMC Cloud Start-up Guide.

2 Setup for ProtoNode
2.1 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
FPC-N34-0701
ProtoNode FPC-N35
FPC-N35-0702
Figure 1: ProtoNode Part Numbers
•FPC-N34 units have the following 3 ports: RS-485 + Ethernet + RS-485
•FPC-N35 units have the following 3 ports: LonWorks + Ethernet + RS-485
2.2 Point Count Capacity
The total number of registers presented the device(s) attached to the ProtoNode cannot exceed:

2.3 Configuring Device Communications
2.3.1 Confirm the Device and ProtoNode COM Settings Match
•Any 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.

2.3.2 Set Node-ID for Any Device Attached to the ProtoNode
•Set Node-ID for any device attached to ProtoNode. The Node-ID needs to be uniquely assigned
between 1 and 255.
•Document the Node-ID that is assigned. The Node-ID assigned is used for deriving the Device
Instance for BACnet/IP and BACnet MS/TP. (Section 8.5)
NOTE: The Modbus TCP/IP field protocol Node-ID is automatically set to be the same value as the
Node-ID of the device.

ProtoNode 6 Pin Phoenix connector:
•The 6 pin Phoenix connector is the same for ProtoNode FPC-N34 and FPC-N35 (LonWorks).
•Pins 1 through 3 are for RS-485 devices.
oUse standard grounding principles for RS-485 GND
•Pins 4 through 6 are for power. Do not connect power until Section 3.5.

3.2.1 Biasing the 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 7)
•Only turn biasing ON:
oIF the BMS cannot see more than one device connected to the ProtoNode
oAND all the settings (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.

3.2.2 End of Line Termination Switch for the 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).

3.3 Serial Network (FPC-N34): Wiring Field Port to RS-485 Network
•Connect the RS-485 network wires to the 3-pin RS-485 connector on ProtoNode as shown below
in Figure 9.
oUse standard grounding principles for RS-485 GND

•If the ProtoNode is the last device on the trunk, then the end of line (EOL) termination switch needs
to be enabled. See Figure 10 for the orientation of switch positions referenced below.
oThe default setting from the factory is OFF (switch position = right side)
oTo enable the EOL termination, turn the EOL switch ON (switch position = left side)
•If more than one RS-485 device is connected to the network, then the field bias resistor switch
needs to be enabled to ensure proper communication. See Figure 10 for the orientation of switch
positions referenced below.
oThe default factory setting is OFF (switch position = right side)
oTo enable biasing, turn the bias switch ON (switch position = left side)
NOTE: Biasing only needs to be enabled on one device. The ProtoNode has 510 ohm resistors
that are used to set the biasing.

4 Connect the PC to the ProtoNode
4.1 Connecting to the Gateway via Ethernet
Connect a Cat-5 Ethernet cable (straight through or cross-over) between the local PC and ProtoNode.
4.1.1 Changing the Subnet of the Connected PC
The default IP Address for the ProtoNode is 192.168.1.24, Subnet Mask is 255.255.255.0. If the PC and
ProtoNode are on different IP networks, assign a static IP Address to the PC on the 192.168.1.xxx network.
For Windows 10:
•Find the search field in the local computer’s taskbar (usually to the right of the windows icon )
and type in “Control Panel”.
•Click “Control Panel”, click “Network and Internet” and then click “Network and Sharing Center”.
•Click “Change adapter settings” on the left side of the window.
•Right-click on “Local Area Connection” and select “Properties” from the dropdown menu.
•Highlight and then click the Properties button.
•Select and enter a static IP Address on the same subnet. For example:
•Click the Okay button to close the Internet Protocol window and the Close button to close the
Ethernet Properties window.

5 Setup Web Server Security
Navigate to the IP Address of the ProtoNode on the local PC by opening a web browser and entering the
IP Address of the ProtoNode; the default Ethernet address is 192.168.1.24.
NOTE: If the IP Address of the ProtoNode has been changed, the assigned IP Address can be
discovered using the FS Toolbox utility. See Section 10.1 for instructions.
5.1 Login to the FieldServer
The first time the FieldServer GUI is opened in a browser, the IP Address for the gateway will appear as
untrusted. This will cause the following pop-up windows to appear.
