1 BACNET IOT GATEWAY DESCRIPTION
The BACnet IoT Gateway provides a connection from BACnet devices and networks to the cloud. This is
achieved via a discovery tool built into the hardware for any BACnet/IP or BACnet MS/TP network without
any additional dongles or installations needed. BBMD BACnet network discovery is also supported.
The BACnet IoT Gateway comes in three model types. The FS-IOT-BAC model offers two RS-485 ports
and one Ethernet 10/100 port. The FS-IOT-BACW model has two RS-485 ports, one Ethernet 10/100 port
and supports Wi-Fi network connection. The FS-IOT-BACA, FS-IOT-BACV and FS-IOT-BACF models offer
cellular connections for the chosen carrier (AT&T, Verizon or Vodafone), one RS-485 port, one Ethernet
10/100 port and supports Wi-Fi network connection.
Additionally, Wi-Fi models act as a Wi-Fi access point for modern web-based configuration and remote
access from any mobile device without user restrictions.
The BACnet IoT Gateway also includes Monitor View, Data Log Viewer, Virtual Points and Event Log data
analysis features that allow tracking and logging of individual device data points across the connected
network in real-time.
The BACnet IoT Gateway is cloud ready and connects with MSA Safety’s SMC Cloud.
NOTE: For SMC Cloud information, refer to the SMC Cloud Start-up Guide online through the
Sierra Monitor website.
NOTE: The latest versions of instruction manuals, driver manuals, configuration manuals and
support utilities are available online through the Sierra Monitor website.

2.4 FS-IOT-BACA/V/F: Inserting the SIM Card
NOTE: A micro 4G SIM card must be purchased from an AT&T, Verizon or Vodafone cellular
provider to set up cellular functionality and create a data plan for the ProtoAir. SIM card
vendor contact information is available at the end of the section.
Insert the SIM card into the Micro SIM card slot with the chip on the SIM card facing away from
the cellular antenna as shown below.
See Section 7 to complete cellular setting configuration.
SIM Card Vendor Contact Information:
Verizon
A business contract is required to purchase a Verizon SIM card. The IMEI of the ProtoAir is required to
purchase the Verizon SIM card.
AT&T
Please call AT&T Customer Service at 800.331.0500 or find the nearest AT&T store.

3.3 10/100 Ethernet Connection Port
The Ethernet Port is used both for BACnet/IP communications and for configuring the BACnet IoT Gateway
via the Web App. To connect the BACnet IoT Gateway, either connect the PC to the Gateway’s Ethernet
port or connect the Gateway and PC to an Ethernet switch. Use Cat-5 cables for the connection.
NOTE: The Default IP Address of the BACnet IoT Gateway is 192.168.2.101, Subnet Mask is
255.255.255.0.

6 SETUP WEB SERVER SECURITY
6.1 Login to the FieldServer
The first time the FieldServer GUI is opened in a browser, the IP Address for the gateway will appear as
untrusted. This will cause the following pop-up windows to appear.
•When the Web Server Security Unconfigured window appears, read the text and choose whether
to move forward with HTTPS or HTTP.
•When the warning that “Your connection is not private” appears, click the advanced button on the
bottom left corner of the screen.
