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.
