Quick Start Guide
1. Methods of Configuration: (Section 2.2)
•Auto-Discovery: See Figure 1 for the table of devices that support automatic configuration.
•Web Configurator: For devices that cannot be automatically configured, use a web browser to
access the Web Configurator page.
2. Record the information about the unit. (Section 3.1)
3. Check that the ProtoAir and customer device COM settings match. (Section 3.3)
4. Connect the ProtoAir 3 pin RS-485/RS-232 R1 port to the RS-485 or RS-232 network connected to
each of the devices. (Section 4.1)
5. If using a serial field protocol:
Connect the ProtoAir 3 pin RS-485 R2 port to the field protocol cabling. (Section 4.2)
6. Connect power to ProtoAir 3 pin power port. (Section 4.5)
7. Connect a PC to the ProtoAir via Ethernet cable. (Section 5)
8. Auto-Discovery Devices: On the Web Configurator page, click the Discovery Mode button at the bottom
of the screen. It may take about 3 minutes for all the devices to be discovered and the configuration file
to be built. (Section 6.3.1)
9. Web Configuration Devices: Use a web browser to access the ProtoAir Web Configurator page to
select the profile of the device attached to the ProtoAir and enter any necessary device information.
Once the device is selected, the ProtoAir automatically builds and loads the appropriate configuration.

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 Pure Humidifier’s devices (hereafter
simply called “device”) connected to the ProtoAir and automatically configures them for BACnet/IP, BACnet
MS/TP, Modbus TCP/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.

2.2 Methods of Configuration
The ProtoAir offers two methods of configuration:
•Auto-Discovery: Supported RS-485 devices can be automatically detected and identified for
addition to the ProtoAir’s configuration via the ProtoAir’s Web Configurator. (Section 6.3.1)
•Web Configurator: Devices that cannot be identified by Auto-Discovery must be configured to the
gateway by selecting profiles on the ProtoAir’s Web Configurator. The Web Configurator shows all
the stored profiles/devices on the ProtoAir. It will also show all the devices that were previously
discovered or selected. To configure, select a device and enter the Station Address. Once all
required device profiles are saved, the ProtoAir automatically builds and downloads the
configuration for the desired protocol. (Section 6.3.2)

3 PROTOAIR SETUP
3.1 Record Identification Data
Each ProtoAir 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
ProtoAir
FPA-W44-1732
Figure 2: ProtoAir Part Numbers
•FPA-W44 units have the following 4 ports: Ethernet + Wi-Fi + RS-485 + RS-485/RS-232
3.2 Point Count Capacity and Registers per Device
The total number of registers presented the device(s) attached to the ProtoAir cannot exceed:

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 the Station Address for Any Device Attached to the ProtoAir
•Set the Station Address for the device attached to ProtoAir. The Station Address needs to be
uniquely assigned between 1 and 255.
•Document the Station Address that is assigned. The Station Address assigned is used for
deriving the Device Instance for BACnet/IP and BACnet MS/TP. (Section 6.5)
NOTE: The Metasys N2 and Modbus TCP/IP field protocol Station Addresses are automatically set
to be the same value as the Station Address of the device.
3.4 Attaching the Antenna
Wi-Fi Antenna:
Screw in the Wi-Fi antenna to the front of the unit as shown in Figure 54.
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 or RS-232 devices on the R1 port.
NOTE: Use standard grounding principles for RS-485 or RS-232 GND.
To switch the R1 port between RS-485 and RS-232, move the number 4 DIP Switch left for RS-485 and
right for RS-232.

4.3 Bias Resistors
To enable Bias Resistors, move both the BIAS- and BIAS+ dip switches to the right as shown in
Figure 11.
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 12.
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.

•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.
