2 INTRODUCTION
2.1 ProtoAir Gateway
The ProtoAir wireless gateway is an external, high performance building automation multi-protocol
gateway that is preconfigured to automatically communicate between Chromalox’s devices (hereafter
simply called “device”) connected to the ProtoAir and automatically configures them for BACnet/IP, BACnet
MS/TP, Modbus TCP/IP, EtherNet/IP and Metasys®
2
N2.
It is not necessary to download any configuration files to support the required applications. The ProtoAir is
pre-loaded with tested profiles/configurations for the supported devices.
FPA-W44 Connectivity Diagram:
The ProtoAir can connect with Sierra Monitor’s SMC Cloud. The SMC Cloud allows technicians, the OEM's
support team and Sierra Monitor's support team to remotely connect to the ProtoAir. 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.

3.3 Configuring Device Communications
3.3.1 Confirm the Device and ProtoAir COM Settings Match
•Any connected serial device MUST have the same baud rate, data bits, stop bits, and
parity settings as the ProtoAir.
•Figure 5 specifies the device serial port settings required to communicate with the ProtoAir.

3.3.2 Set Node-ID for Any Device Attached to the ProtoAir
•Set Node-ID for the device attached to ProtoAir. 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 9.5)
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.
3.3.3 Set IP Address for Any Ethernet Device Connected to the ProtoAir
•Ensure any device is set to Modbus TCP/IP to communicate with the ProtoAir.
•The device needs to be on the same IP subnet as the ProtoAir and the configuration PC.
•Record the following device information to start the setup:
oIP Address
oIP port
oNode-ID
NOTE: This information is required for Section 9.2.
3.4 Attaching the Antenna
Wi-Fi Antenna:
Screw in the Wi-Fi antenna to the front of the unit as shown in Figure 53.
NOTE: Using an external antenna is also an option. An external antenna can be plugged into the
SMA connector. The best antenna for the job depends on the range, topography and
obstacles between the two radios.

4 INTERFACING PROTOAIR TO DEVICES
4.1 Device Connections to ProtoAir
The ProtoAir has a 3-pin Phoenix connector for connecting RS-485 devices on the R1 port.
NOTE: Use standard grounding principles for RS-485 GND.
4.2 Wiring Field Port to RS-485 Serial Network
•Connect the RS-485 network wires to the 3-pin RS-485 connector on the R2 port. (Figure 7)
oUse standard grounding principles for RS-485 GND
•See Section 5 for information on connecting to an Ethernet network.

4.3 Bias Resistors
To enable Bias Resistors, move both the BIAS- and BIAS+ dip switches to the right as shown in
Figure 8.
The ProtoAir bias resistors are used to keep the RS-485 bus to a known state, when there is no
transmission on the line (bus is idling), to help prevent false bits of data from being detected. The bias
resistors typically pull one line high and the other low - far away from the decision point of the logic.
The bias resistor is 510 ohms which is in line with the BACnet spec. It should only be enabled at one
point on the bus (for example, on the field port were there are very weak bias resistors of 100k). Since
there are no jumpers, many gateways can be put on the network without 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 serial port.
NOTE: If the gateway is already powered on, DIP switch settings will not take effect unless the
unit is power cycled.

4.4 Termination Resistor
If the ProtoAir is the last device on the serial trunk, then the End-Of-Line Termination Switch needs to be
enabled. To enable the Termination Resistor, move the TERM dip switch to the right as shown in
Figure 9.
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 serial port.
NOTE: If the gateway is already powered on, DIP switch settings will not take effect unless the
unit is power cycled.

Power Requirement for ProtoAir External Gateway
Current Draw Type
ProtoAir Family

125mA
NOTE: These values are ‘nominal’ and a safety margin should be added to the power supply of
the host system. A safety margin of 25% is recommended.
Figure 10: Required Current Draw for the ProtoAir
Apply power to the ProtoAir as shown below in Figure 11. Ensure that the power supply used complies
with the specifications provided in Appendix D.1.
•The ProtoAir accepts 9-30VDC or 24VAC on pins L+ and N-.
•Frame GND should be connected.

5 CONNECT THE PC TO THE PROTOAIR
5.1 Connecting to the ProtoAir via Ethernet
Connect a Cat-5 Ethernet cable (straight through or cross-over) between the local PC and ProtoAir.
5.1.1 Changing the Subnet of the Connected PC
The default IP Address for the ProtoAir is 192.168.1.24, Subnet Mask is 255.255.255.0. If the PC and
ProtoAir 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.

6.2.1 Update Wired Network Settings
IP Settings tab is the landing page when selecting Network Settings on the navigation tree. To change the
IP settings, follow these instructions:
•Enable DHCP Client State to automatically assign IP Settings or modify the settings manually as
needed, via these fields: IP Address, Netmask, Default Gateway and Domain Name Server1/2.
NOTE: If connected to a router, set the Default Gateway to the same IP Address as the router.
•Click Update IP Settings, then click on System Restart to restart the Gateway and activate the new
IP Address.
•Connect the ProtoAir to the local network or router.
NOTE: If the FS-GUI was open in a browser, the browser will need to be pointed to the new IP
Address of the ProtoAir before the FS-GUI will be accessible again.
