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 Siemens’devices (hereafter simply
called “device”) connected to the ProtoAir and automatically configures them for BACnet/IP, BACnet
MS/TP, EtherNet/IP and Modbus TCP/IP.
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 Modbus Device Communications
3.3.1 Input COM Settings on Any Device Connected to the ProtoAir
•Any connected serial device MUST have the same baud rate, data bits, stop bits, and
parity settings as the ProtoAir.
•Figure 4 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 to 1.
•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 7)
NOTE: The Modbus TCP/IP field protocol Node-IDs are automatically set to be the same value as
the Node-ID 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 34.
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.

4.3 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.

5 CONNECT THE PC TO THE PROTOAIR
There are two ways to connect the PC to the ProtoAir, either by Ethernet cable (Section 5.1) or Wi-Fi
Access Point (Section 5.2).
5.1 Connecting to the ProtoAir via Ethernet
First, connect a Cat-5 Ethernet cable (straight through or cross-over) between the local PC and ProtoAir.
5.1.1 Enable Access Through the Local Browser
There are two methods to enable access to the ProtoAir in the local browser, either by changing the
subnet of the connected PC (Section 5.1.1.1) or using the FieldServer Toolbox to change the IP
Address of the ProtoAir (Section 5.1.1.2).
NOTE: Only perform one method or the other.
5.1.1.1 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.
Ethernet Port
Figure 12: Ethernet Port Location

Siemens ProtoAir Start-up Guide
Page 17 of 66
5.1.1.2 Changing the IP Address of the ProtoAir with FieldServer Toolbox
•Ensure that FieldServer Toolbox is loaded onto the local PC. Otherwise, download the
FieldServer-Toolbox.zip via the Sierra Monitor website’s Software Downloads.
•Extract the executable file and complete the installation.
•Double click on the FS Toolbox Utility and click Discover Now on the splash page.
•Find the desired gateway and click the Configure Device button (gear icon) to the right of the
gateway information.
NOTE: If connectivity status is green, then the IP Address doesn’t need to be changed (the
ProtoAir is already on the same subnet). Skip the rest of the section and go to Section 6.
•Select Network Settings in the Configure Device window.
•Modify the IP Address (N1 IP Address field) of the gateway Ethernet port.
oChange additional fields as needed
NOTE: If the gateway is connected to a router, the Default Gateway field of the gateway should be
set to the IP Address of the connected router.
NOTE: Do not change the DHCP Server State (N1 DHCP Server State field).
NOTE: If DNS settings are unknown, set DNS1 to “8.8.8.8” and DNS2 to “8.8.4.4”.
•Click Update IP Settings, then click the “Change and restart” button to reboot the Gateway and
activate the new IP Address. See the FieldServer Toolbox and GUI Manual for more information.

Siemens ProtoAir Start-up Guide

5.2 Connecting to the ProtoAir Over Wi-Fi Access Point
When the ProtoAir is first powered up, the Wi-Fi Access Point will be enabled allowing direct connection
to the ProtoAir with Wi-Fi.
To connect to the ProtoAir Wi-Fi Access Point:
•Click the icon (found in the bottom-right corner of the computer screen) to open the available
Wireless Network Connections.
•Select the desired ProtoAir and click Connect.
•Enter the Security key. The default is 12345678.
The available Wireless Network Connection menu should now show that the computer is connected to
the ProtoAir.

6 CONFIGURE THE PROTOAIR
6.1 Accessing the ProtoAir Web Configurator
•Navigate to the IP Address of the ProtoAir on the local PC using one of two methods:
oOpen a web browser and enter the IP Address of the ProtoAir; the default Ethernet address is
192.168.1.24, the default Wi-Fi Access Point address is 192.168.50.1
oIf using the FieldServer Toolbox (Section 5.1.1.2), click the Connect button
NOTE: If the IP Address of the ProtoAir has been changed, the IP Address can be discovered
using the FS Toolbox utility. See Appendix A.1 for instructions.
6.2 Select Field Protocol Configuration
•On the Web Configurator page, the first configuration parameter is the Protocol Selector.
•Select the configuration desired, using the number key under the Parameter Description header,
and click the Submit button.
oA message will appear at the top of the screen stating that the update was completed and to
restart the system.
•Click the System Restart button on the bottom of the screen and wait for the system to reset.

6.3 Setting ProtoAir Active Profiles
•In the Web Configurator, the Active Profiles are shown below the configuration parameters. The
Active Profiles section lists the currently active device profiles, including previous Web Configurator
additions. This list is empty for new installations, or after clearing all configurations. (Figure 14)
