Page 3: Introduction: Who Is This Manual For
This manual is written for engineers and technicians who are responsible for the design, installation, and configuration of BACnet-based building automation systems. To successfully configure the B3075’s core routing functionality, you will need to be familiar with the following terminology and concepts, at a minimum:... -
Page 4: What Does A Bacnet/Ip To Bacnet/Ip Router Do, And Why Is It Used
The B3075 has two Ethernet ports that are used for BACnet/IP communication, and each of those ports will be assigned an IP address appropriate for the directly connected IP network. The B3075 is not an IP router, so the IP addresses of devices connected to the backbone network will not appear on the private network, and the IP addresses of devices connected to the private network will not appear on the backbone network. -
Page 5: B3075 Functionality Overview
The B3075 is a BACnet Device, as defined in the BACnet Standard. The Device Object instance number (a.k.a. “Device ID”) and the Device Object name (a.k.a. “Device Name”) are configurable. The B3075 can be configured to be a BBMD on the Customer port, with optional support for Foreign Devices. -
Page 6: The B3075 Hardware
B3075 will perform substantially in accordance with the applicable datasheet, under normal and proper use, for two (2) years from the date the B3075 is delivered to the Buyer. This warranty will be void if, in Cimetrics’ reasonable opinion, the defect was caused by (a) improper handling, configuration, operation, or testing by anyone other than Cimetrics;... -

(see the section Activate New Configuration). Even if you lose the “admin” password, you can reset the B3075 to factory default settings and recover the factory default admin password using the procedure described in section How to reset to factory default settings if the admin password is unknown. -

B3075’s non-volatile memory and reboot. See the section Activate New Configuration. BACnet Device Settings The B3075 contains a basic BACnet Device that will respond to a few BACnet service requests. See the B3075’s BACnet PICS document for details. -

IP network to which it is connected has a DHCP server. Note: Although the B3075 can be configured to use DHCP to obtain an IP address and other network parameters, the product is a BACnet anchor point used to maintain the integrity of the building automation network. -
Page 11: Bbmd Settings
BBMD Settings The BBMD function can be enabled on the Customer port, but not on the Private port. For general information about how BBMDs work, see the Appendix: What does a BBMD do?. The most complex configuration parameter in a BBMD is the Broadcast Distribution Table (“BDT”), which contains the list of BBMDs (identified by each BBMD’s IP addresses and UDP port) that will receive forwarded BACnet/IP broadcasts from this BBMD. -

255.255.255.255 would be used today, so accepting that default value is almost always correct. Note: It is not necessary for you to include the B3075’s own IP address in the BDT Entries table. If you do include the IP address of the B3075 in that table, then on the Activate Configuration web page you may see a spurious warning message such as the following: “Some BDT addresses are... - Page 13 Parameters for BACnet NAT traversal A B3075 with the BBMD function enabled on the Customer port can be configured to communicate through a network address translation (NAT) router, but this requires careful network design and configuration of the B3075. Please refer to clause J.7.5, “BBMD Operation with Network Address...

B3075’s non-volatile memory. Note that if the B3075 is disconnected from its power source or a logout occurs (manually by the user or automatically due to a timeout), all configuration changes that have not been activated will be discarded. -

PC connected to the Customer network or the Private network. When this feature is enabled, the B3075’s configuration interface can be accessed at the IP address of the B3075’s Customer port from the Customer network or at the IP address of the B3075’s Private port from the Private network. -
Page 16: Internal Diagnostics
The Status and Statistics page shows the output of various internal tools that, in aggregate, provide a technically dense view of the health of the B3075 since its last reboot. If you suspect that the B3075 is malfunctioning or that it might not be correctly configured, you can click the “Save Internal Diagnostic Info”... -
Page 17: Network Packet Capture
“Download files” to download the compressed packet capture file(s). The packet capture files created by the B3075 are managed as a ring buffer: When the last file is full, the oldest file is removed, and the resulting free space is reused to create a new file. Under normal conditions, packet capture continues until explicitly stopped by the user. - Page 18 USB memory stick to store the files containing the captured packets. Insert a formatted memory stick into one of the B3075’s USB ports, and then navigate to (or refresh) the Network Packet Capture web page. If the memory stick is recognized by the B3075, you should now see something like the following: Select the “USB disk”...

Both modes may be used simultaneously, with a limit of one active client per mode. In both modes, the B3075’s built-in VPN server is present on the Customer port. For each mode, select an unused IP address on the Private network for use by the VPN’s virtual interface. -
Page 20: Replacing The Web Server's Private Key And Certificates
Replacing the Web Server’s Private Key and Certificates The B3075’s web server uses the HTTPS protocol for communication with web browsers. The B3075 ships with a pre-assigned private key and a self-signed operational certificate that are used by the B3075’s web server. -
Page 21: Managing B3075 Configuration
Managing B3075 Configuration You may save the B3075’s configuration in a file, and later load the configuration file into the same B3075 or into a different B3075 that is running compatible firmware. After you load a configuration file you may make additional configuration changes if desired. -
Page 22: Resetting The B3075 To Factory Default Settings
PC, an Ethernet cable, and physical access to the B3075. The recommended procedure is as follows: 1. Connect a USB mouse to one of the B3075’s USB ports, and then power cycle the B3075 by disconnecting its external power adapter from AC power for several seconds. It will take a couple of minutes for the B3075 to reboot after the power is restored. - Page 23 4. Click on the “Reset configuration” button. If all is well, you should see a web page like the following: You can reconfigure the B3075 as required after you login using the factory default admin password, which is shown on the web page.

Page 24: Appendix: What Does A Bbmd Do
Appendix: What does a BBMD do? BBMDs forward BACnet broadcast messages within BACnet/IP networks that span multiple IP subnetworks. The BACnet protocol utilizes broadcast messages for certain functions, such as the discovery of BACnet devices and for time synchronization. Also, BACnet networks and BACnet routers are discovered using BACnet broadcast messages.
