Quick Start Guide
1. Record the information about the unit. (Section 3.1)
2. Set COM settings for the devices that will be connected to ProtoAir. (Section 3.3)
3. Connect Power to ProtoAir’s 3 pin connector. (Section 4)
4. Connect a PC to the ProtoAir via Ethernet cable or connect using Wi-Fi access point to ensure the
PC is on the same subnet as the ProtoAir. Set the IP Address of the ProtoAir to the subnet of the
intended Network and reset IP details of the PC. (Section 5)
5. Use a web browser to access the ProtoAir Web Configurator page to select the profiles of the devices
attached to the ProtoAir and enter the IP Address of each device. Once the devices are selected, the
ProtoAir automatically builds and loads the appropriate configuration. (Section 6)

2 INTRODUCTION
2.1 ProtoAir Gateway
The ProtoAir wireless gateway is an external, high performance building automation multi-protocol
gateway that is preconfigured to auto-discover any of Siemens’products (hereafter called “device”)
connected to the ProtoAir and automatically configures them for BACnet/IP, Modbus TCP/IP and
EtherNet/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.

3 PROTOAIR SETUP
3.1 Record Identification Data

3.3 Configuring Device Communications
3.3.1 Input COM Settings on the Device Connected to the ProtoAir
•The 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.

NOTE: The COM parameters are adjustable.
3.3.2 Set Node-ID for the Device Attached to the ProtoAir
•Set Node-ID for the device attached to ProtoAir to 1.
•Document the Node-ID that is assigned to the device. The Node-ID’s assigned are used for
deriving the Device Instance for BACnet/IP. (Section 3.3.3)
NOTE: The Modbus TCP/IP field protocol Node-IDs are automatically set to be the same value as
the Node-ID of the device.
3.3.3 BACnet: Calculating the Default Device Instance
•The Device Instance value is automatically generated using the following formula:
BACnet Device Instance = (Device Node-ID) + (Default Node Offset)
NOTE: The default Node Offset is 50,000.
For example, if Device A has a Node-ID of 1 then:
BACnet Device Instance A = (1) + (50000) = 50001
NOTE: The Node-ID is set in Section 3.3.2.
•To reach a specific BACnet Device Instance result, refer to Section 7.
3.4 Attaching the Antenna
Wi-Fi Antenna:
Screw in the Wi-Fi antenna to the front of the unit as shown in Figure 32.

4.1.1 Bias Resistor DIP Switches
To enable Bias Resistors, move both the BIAS- and BIAS+ dip switches to the right.
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.
In the RS-485 carrier, 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 (on the Brian field port were there are very weak bias resistors of
100k). Since there are no jumpers, many Brains can be put on 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.

4.1.2 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.
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.

5 CONNECT THE PC TO THE PROTOAIR OVER ETHERNET OR WI-FI
5.1 Connecting to the ProtoAir via Ethernet
First, connect a CAT5 Ethernet cable (straight through or cross-over) between the local PC and ProtoAir.
There are two ways to access the ProtoAir via an Ethernet connection, either by changing the subnet of
the connected PC or using the FieldServer Toolbox to change the IP Address of the ProtoAir.
5.1.1 Changing the Subnet of the Connected PC
The default IP Address for the ProtoAir Ethernet connection 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:
Right click on > >
> >
Right-click on Local Area Connection > Properties
Highlight >
Use the following IP Address:
Click twice.
Ethernet Port

5.1.2 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 Resource Center 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.
•Select Network Settings in the Configure Device window.
•Modify the IP Address (N1 IP Address field) of the gateway Ethernet port.
oThe following fields may also be changed as needed: Netmask (N1 Netmask field), DHCP
Client State (N1 DHCP Client State field), IP Gateway (Default Gateway field) and DNS 1 & 2
(Domain Name Server fields)
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 on the Change and Restart to restart the Gateway and
activate the new IP Address.

5.2 Connecting to the ProtoAir via 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 via 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.

5.3 Updating Network Settings
5.3.1 Navigate to the FS-GUI Network Settings
After setting a local PC on the same subnet as the ProtoAir (Section 5.1 or Section 5.2), open a web
browser on the PC 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. Alternatively, the Web Configurator
page can be accessed by clicking the Connect button in the FieldServer Toolbox (Section 5.1.2).
NOTE: If the IP Address of the ProtoAir was previously changed, the assigned IP Address can be
discovered using the FS Toolbox utility. See Appendix A.1 for instructions.
•From the Web Configurator landing page, click the “Diagnostics & Debugging” button to open the
FS-GUI page.
•Find the Navigation tree on the left side of the screen.

5.3.2 IP 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 the ProtoAir is connected to a router, the Default Gateway of the ProtoAir should be set
to the same IP Address of the router.
•Click Update IP Settings, then click on System Restart to restart the Gateway and activate the
new IP Address.
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.
