1 BACNET ROUTER DESCRIPTION
The BACnet Router provides stand-alone routing between BACnet networks such as BACnet/IP, BACnet
Ethernet, and BACnet MS/TP –thereby allowing the system integrator to mix BACnet network
technologies within a single BACnet internetwork. There are three physical communication ports on the
BAS Router. One is a 10/100 Mbps Ethernet port and the other two are RS-485 MS/TP ports.
Configuration is accomplished via a web page.
The BACnet Router is cloud ready and connects with Sierra Monitor’s SMC Cloud.
NOTE: For SMC Cloud information, refer to the SMC Cloud Start-up Guide online at the Sierra
Monitor website.
NOTE: The latest versions of instruction manuals, driver manuals, configuration manuals and
support utilities are available online at the Sierra Monitor website.

2 EQUIPMENT SETUP
2.1 Mounting
The BACnet Router can be mounted using the DIN rail mounting bracket on the back of the unit.

3 INSTALLING THE BACNET ROUTER
3.1 Connecting the R1 and R2 Ports
The R1 and R2 Ports are RS-485.
NOTE: For the R1 Port, ensure RS-485 is selected by checking that the number 4 DIP Switch is set
to the left side.
Connect to the 3-pin connector(s) as shown below.
The following baud rates are supported:
9600, 19200, 38400, 76800

3.2 10/100 Ethernet Connection Port
The Ethernet Port is used both for BACnet/IP communications and for configuring the BACnet Router via
the Web App. To connect the BACnet Router, either connect the PC to the Router’s Ethernet port or
connect the Router and PC to an Ethernet switch. Use Cat-5 cables for the connection.
NOTE: The Default IP Address of the BACnet Router is 192.168.2.101, Subnet Mask is
255.255.255.0.

4 POWER UP THE DEVICE
Check power requirements in the table below:
Power Requirement for External Gateway
Current Draw Type
BACnet Router Family
12VDC
24V DC/AC
FS-EXPLORER-BAC2 (Typical)
250mA
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 5: Required Current Draw for the Gateway
Apply power to the BACnet Router as shown below in Figure 6. Ensure that the power supply used
complies with the specifications provided in Appendix B.1.
•The gateway accepts 12-24VDC or 24VAC on pins 4 and 5.
•Frame GND should be connected.

5 CONNECTING TO THE BACNET ROUTER
The FieldServer Toolbox Application can be used to discover and connect to the BACnet Router on a
local area network. To connect to the BACnet Router over the Internet using Toolbox, add the Internet
exposed IP Address of the Router by clicking on the button, or alternatively enter the Internet
exposed IP Address in a web browser directly.
5.1 Using the FieldServer Toolbox
•Install the FS Toolbox application from the USB drive or download it from the Sierra Monitor
website.
•Use the FS Toolbox application to find the BACnet Router, change the IP Address details (if
required) and launch the Web App (by clicking the Connect button).
+

5.2 Using a Web Browser Directly
•Open a Web Browser and connect to the BACnet Router’s Default IP Address. The Default IP
Address of the BACnet Router is 192.168.2.101, Subnet Mask is 255.255.255.0
•If the PC and the BACnet Router are on different IP Networks, assign a Static IP Address to the
PC on the 192.168.2.X network.
NOTE: The FieldPoP™ tab (see Figure 7) allows users to connect to the SMC
Cloud, Sierra Monitor’s device cloud solution for IIoT. The SMC Cloud enables secure
remote connection to field devices through a FieldServer and its local applications for
configuration, management, maintenance. For more information about the SMC Cloud,
refer to the SMC Cloud Start-up Guide.

6 CONFIGURING THE BACNET ROUTER
6.1 Settings
6.1.1 Button Functions
•Save –write the currently displayed settings to the device. A
restart will be required to apply the updated settings.
•Reload –discard the currently displayed settings and reload
the settings stored on the device. This will undo any unsaved
edits.
•Defaults –discard the currently displayed settings and load
default settings. This must still be saved and the device must
be restarted for the default settings to be applied.
•Restart –restarts the device.
6.1.2 Multiple Connections
•Network Number –set up the BACnet network number for the connection. Legal values are
1-65534. Each network number must be unique across the entire BACnet internetwork.
•Enable –enable or disable the connection; note that BACnet/IP Primary is always enabled.
6.1.3 BACnet Device
•Device Instance and Device Name –a BACnet
Router must provide a Device Object. Configure its
name and Instance Number here. Take care to select
a Device Instance Number that is unique across the
entire BACnet internetwork.
•Device Location –enter a location for the Device.
The location may not contain any commas.
•Device Connection –select which connection to
bond the BACnet device settings.

BACnet Router Start-up Guide
Page 13 of 32
6.1.4 BACnet/IP
•IP Port –the BACnet/IP default is 47808 (0xBAC0),
but a different port number may be specified here.
•IP Port –this MUST be different to the IP Port used
on the BACnet/IP Primary connection. Default is
47809 (0xBAC1).
•BBMD Connection –select which connection to
bond the BACnet/IP BBMD settings.
•Public IP Address and Port –if the BBMD is being
accessed across a NAT Router, then these values
must be configured with the public IP Address and
Port by which the BBMD can be reached from across
the NAT Router. The Public IP Address and Port
would also be used in the BDT of remote BBMD's that
need to reach this BBMD across the NAT Router. If
no NAT Router is being used, these fields can be left
blank. For example, type into a Google browser “my
IP Address” to see the local PC’s Public IP Address.

6.1.5 BACnet MS/TP, BACnet Ethernet and BACnet Explorer
•Max Info Frames –the number of transactions the
Router may initiate while it has the MS/TP token.
Default is 50.
•Max Master –the highest MAC address to scan for
other MS/TP master devices. The default of 127 is
guaranteed to discover all other MS/TP master
devices on the network.
•MAC Address –legal values are 0 to 127, must be
unique on the physical network.
•Baud Rate –the serial baud rate used on the
network.
•Token Usage Timeout (ms) –the number of
milliseconds the router will wait before deciding that
another master has dropped the MS/TP token. This
value must be between 20ms and 100ms. Choose a
larger value to improve reliability when working with
slow MS/TP devices that may not be able to meet
strict timing specifications.
