Quick Start Guide
1. Record the informationabout the unit. (Section 2.1)
2. Check that the ProtoNode and customer device COMsettingsmatch. (Section 2.3)
3. If connecting to a serial device:
Connect the ProtoNode 3 pin RS-485 R1 port to the RS-485 network connected to each of the
devices. (Section 3.1)
4. If using a serial field protocol:
Connect the ProtoNode 3 pin RS-485 R2 port to the field protocol cabling. (Section 3.2)

Description
Mestek ProtoNodeStart-up Guide 7
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 Mestek’sdevices (hereafter simply called “device”)
connectedto the ProtoNode and automaticallyconfiguresthem for BACnet/IP, BACnet MS/TP, Modbus
TCP/IP and Metasys®
1
N2 by JCI.
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.
FPC-N54 Connectivity Diagram:
The ProtoNode can connect with the MSA Grid –FieldServer Manager.The FieldServerManager allows
technicians,theOEM'ssupportteamandMSASafety'ssupportteamtoremotelyconnecttotheProtoNode.
The FieldServer Manager providesthe following capabilities for any registered devices in the field:
•Remotely monitor and control devices.
•Collect device data and view it on the Dashboard and the MSA Smart Phone App.
•Create user defined device notifications(alarm, trouble and warning) via SMS and/or Email.
•Generate diagnostic captures(as needed fortroubleshooting) without going to the site.

2 Setup for ProtoNode
2.1 Record Identificati on Data
Each ProtoNode has a uniquepartnumberlocated on the side or the back of the unit. This number should
be recorded,as it may be required for technical support. The numbersare as follows:

2.3 Configuring Device Communications
2.3.1 Confirm the Device and ProtoNode COM Settings Match
•Any connected serial device 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 thatis assigned. The Node-ID assigned is used for deriving the Device
Instance for BACnet/IP and BACnetMS/TP.(Section 6.5)
NOTE: The Metasys N2 and Modbus TCP/IPfieldprotocol Node-ID is automatically setto be the
same value as the Node-ID of the device.

3 Interfacing Pro toNode to Devices
3.1 Device Connections to ProtoNode
The ProtoNode has a 3-pin Phoenix connector for connecting RS-485 devices on the R1 port.
NOTE: Use standard groundingprinciples for RS-485 GND.

3.3 Bias Resistors
To enable Bias Resistors, move both the BIAS- and BIAS+ dip switches to the right as shown in
Figure 7.
The ProtoNode biasresistors are used to keep the RS-485 bus to a known state, when there is no
transmission on the line (busis idling), to help preventfalse bits of data frombeing detected. The bias
resistors typically pull one line highand the other low - faraway from thedecision pointof the logic.
The bias resistor is 510 ohms which is in line with the BACnetspec. It should onlybe enabled at one
point onthe bus(forexample, on the field port were there are very weak biasresistors of 100k). Since
there are no jumpers, many gateways can be puton the networkwithout running into the bias resistor
limit which is < 500 ohms.
NOTE: See www.ni.com/support/serial/resinfo.htm for additional pictures and notes.
NOTE: The R1 and R2 DIP Switches apply settings to the respective serialport.
NOTE: If the gateway is already powered on, DIPswitch settings will not take effect unless the
unit is power cycled.

3.4 Term i nati on Resistor
If the ProtoNode is the last device on the serial trunk, then the End-Of-Line Termination Switch needsto
be enabled. To enable the Termination Resistor, move the TERM dip switch to the right as shown in
Figure 8.
Termination resistor is also used to reduce noise.It pulls the two lines of an idle bus together. However,
the resistor would override the effect of any bias resistors if connected.
NOTE: The R1 and R2 DIP Switches apply settings to the respective serialport.
NOTE: If the gateway is already powered on, DIPswitch settings will not take effect unless the
unit is power cycled.

Apply power to the ProtoNode as shown below in Figure 10. Ensure thatthe power supply used complies
with the specifications provided in Section 10.
•The ProtoNode accepts 9-30VDC or 24VAC on pins L+and N-.

4 Connect the PC to the Pro toNode
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 defaultIP Addressforthe ProtoNode is 192.168.1.24,SubnetMaskis 255.255.255.0. If the PC and
ProtoNode are on different IP networks, assigna static IPAddress to the PC onthe 192.168.1.xxx network.
ForWindows10:
•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 Addressof the ProtoNode; the defaultEthernetaddressis 192.168.1.24.
NOTE: If the IP Address ofthe ProtoNode has been changed,the assignedIP Address can be
discovered using the FSToolbox utility. See Section7.1 for instructions.
5.1 Logi n to the Fi eldServer
The first timethe FieldServer GUI is opened in a browser, the IP Address for the gatewaywill appear as
untrusted. This will cause the following pop-up windows to appear.
•When the Web Server Security Unconfigured windowappears,read the text and choose whether
to moveforward with HTTPS or HTTP.
•When the warning that “Your connection is not private” appears, click the advanced button on the
bottomleft corner of the screen.

•Additional text will expand belowthe warning, click the underlined text to go to the IP Address. In
the Figure 14 example this text is “Proceed to 10.40.50.94 (unsafe)”.
•When the login screen appears, put in the Username (default is “admin”) and the Password (found
on the label of the FieldServer).
NOTE: There is also a QR code in the top right corner of the FieldServer label that shows the
default unique passwordwhen scanned.
NOTE: A user has 5 attempts to login then there willbe a 10-minute lockout.There is no timeout
on the FieldServer to enter a password.
NOTE: To createindividualuser logins,go to Section 8.7.

NOTE: It may take about 3 minutes for all the devices to be discovered and the configuration file
to be built.
•If the discovery is successful, the device profile should appear under the Active profilestitle.
NOTE: Scroll down the page if the Active profiles header is not visible.
6.3 Verify Devi ce Com m unicati ons
•If using a serial connection, check that the port R1 TX1 and RX1 LEDs are rapidly flashing.
See Section 7.4 for additional LED information and images.
•Confirm the software shows good communicationswithouterrors (Section7.2).
