Chapter 2 MBS Universal BACnet Router (UBR) 8
Connecting two IP networks (UBR-02)
Standalone BBMD (BACnet Broadcast Management Device)
The routers can function as BBMDs in BACnet networks. In the process the
BBMD functionality is used to transport broadcast messages via network
boundaries (IP switches) and to provide availability in the other subnetwork.
Without the use of BBMDs broadcast messages are not be transmitted via an
IP router. The connection of a foreign device (FD) is supported in BBMD mode.
Further characteristics of the MBS Universal BACnet Routers
BACnet Protocol Revision
Conformity with BACnet version 1 protocol revision 14
Diagnosis
Comprehensive diagnostics options to make a start-up easier and to monitor
the function in operation
FD – foreign device
Registration of the router as a foreign device when there is a BBMD in the
network.As a result, the router becomes part of the BACnet/IP network and
receives broadcast messages from other subnetworks.
BBMD IP filter
The BBMD-IP filter function makes it possible to control from which devices
broadcasts are forwarded using the BBMD functionality from the IP subnet.
Individual devices can be excluded using the filters to prevent broadcasts
from these devices being transported over the boundaries of the IP subnet.
BACnet MS/TP
The routers operate as masters on the MS/TP bus. Compatible with the
following speeds: 9600 baud, 19200 baud, 38400 baud, 57600 baud, 76800
baud, 115200 baud.
The bus terminating resistor and the network bias resistors are activated by
the DIP switch. The RS485 interface (BACnetMS/TP) is potential-free.
