MBS UBR-01 | Mk II Classification and purpose 7 von 46
3Classification and purpose
Classification The devices of the UBR (Universal BACnet Router) product family, with
their different interfaces, serve as BACnet router between different
BACnet networks.
Purpose Router from BACnet IP to BACnet MS/TP. The router can be used as a
BACnet router to connect a MS/TP bus to a BACnet IP network.
Standalone BBMD
The router can act as a BBMD in BACnet networks. The BBMD
functionality is used to transport broadcast messages across network
boundaries (IP switches) and thus make them available in the other
subnet. Without the use of BBMDs, broadcast messages are not
transmitted over an IP switch.

MBS UBR-01 | Mk II Features 8 von 46
4Features
BACnet BACnet Protocoll Revision;
the router is compliant with BACnet version 1 protocol revision 22.
Diagnostics;
the router has extensive diagnostic capabilities to assist with
commissioning and to monitor function during operation.
BACnet-IP BBMD – BACnet Broadcast Management Device;
the router can be configured as a BACnet Broadcast Management
Device (BBMD). The connection of Foreign Device (FD) is supported in
BBMD mode.
FD – Foreign Device;
the router can be registered as a foreign device with a BBMD present
in the network. By the registration the router becomes part of the
BACnet/IP network and receives broadcast messages from other
subnets which are provided by the BBMD.
BBMD IP Filter;
using the BBMD-IP Filter function, it is possible to control from which
devices broadcasts are forwarded from the IP subnet via the BBMD
functionality. Individual devices can be excluded via the filters in order
to prevent broadcasts from these devices from being transported
beyond the limits of the IP subnet.
BACnet MS/TP The router works as a master on the MS/TP bus and supports the
following baud rates: 9,600 / 19,200 / 38,400 / 57,600 / 76,800 /
115,200.
The bus terminating resistor and the network bias resistors can be
activated via the DIP switch. The RS485 interface (BACnet MS/TP) is
potential-free.

MBS UBR-01 | Mk II Features 9 von 46
Slave Proxy The router can be configured as a "slave proxy" and responds to
"Who-Is" requests with an "I-Am" message on behalf of connected
MS/TP slave devices. The slave proxy option allows other BACnet
devices to find the connected MS/TP slave devices in the network
without having to configure the slave addresses in each device
individually.
In addition to manual configuration, the router also has the capability
of automatic configuration.
BACnet/SC
Topology
First of all, the network topology of BACnet/SC looks different.
Previously, broadcasts were used for initial
connection attempts in
BACnet, partly with the support of BACnet Broadcast Management
Devices (BBMD)
– not a commonplace method in the IT field.
A different approach has now been chosen for the configuration.
Each network is given a central point, the so
-called hub. It controls the
data traffic between any number of nodes (end devices). It also
analyzes the traffic to determine whether information should be
forwarded to a single node or to all nodes.
A direct connection can also be configured for direct communication
between
two nodes.
Furthermore, BACnet/SC includes a failover mechanism that ensures
that the system remains operational even if the hub fails or is switched
off for maintenance. This new
topology greatly simplifies
configuration, commissioning and management.
At the same time,
BBMDs and their configuration become obsolete.

MBS UBR-01 | Mk II Features 10 von 46
Structure of a typical BACnet/SC network
BACnet/SC
Encryption
and certificates
TCP (Transmission Control Protocol) and WebSocket – two reliable
mechanisms based on the internet protocol (IP) widely used in IT –
are used for secure data transmission. TCP/IP replaces the UDP
(User Data Protocol) network protocol layer previously used by
BACnet; TLS is used to ensure bug-proof and tamper-proof
communications. TLS (Transport Layer Security) is also widely used
as the foundation for secure internet access (https) in IT.
As far as encryption is concerned, a company-wide procedure must
be put in place for the necessary digital certificates.
The certification and registration authorities responsible for the
internet in connection with public key infrastructures are not
specified in BACnet/SC. This means building automation operators
can take account of their individual network structures.

MBS UBR-01 | Mk II Features 11 von 46
To ensure problem-free implementation in existing networks, the
security mechanisms have been defined in BACnet as an additional
data link layer.
The new standard in the latest revision 22is also downwardly
compatible. The advantage of this is that the existing system can
always communicate with the new BACnet/SC devices via
appropriate routers.
Notice
The configuration of BACnet/SC connections is described in this
document under BACnet settings (page 32).

MBS UBR-01 | Mk II Installation 15 von 46
Assembly / Disassembly The device must be mounted on a top-hat rail (DIN top hat TS35
according to EN 60715). The top-hat rail bracket is pre-assembled on
the back of the device. The bracket is hooked into the top-hat rail from
above and fixed to the underside of the bracket with a clearly
perceptible click.
Warning
Electric shock injury hazard!
The device may only be installed in a control cabinet (top-hat rail)
when the power is disconnected.
The system must be disconnected for installation.
Notice
A sufficient distance (≥ 15 mm) to the other components on the top
hat rail is recommended for mounting the device in the control
cabinet.
This ensures better heat dissipation, which can have a positive
influence on the service life of the device.
Disassembly is carried out by unlocking the bracket on the underside
and carefully removing it from the top-hat rail.
Notice
Connecting cables should be unplugged during disassembly, to
avoid damage.
Power connection The device is exclusively operated with protective extra low voltage
(PELV). The permissible voltage range must be taken from chapter 5
Specifications and connected loads.

MBS UBR-01 | Mk II Installation 16 von 46
Warning
Electric shock injury hazard and damage to device!
Connecting the device to deviating, excessively high supply
voltages may lead to serious injuries or death.
The device is operated exclusively with Protective Extra-Low
Voltage. No supply voltages that deviate from the connection
values specified in the Specifications and connected loads may
be used.
The device is supplied with a reverse polarity protected plug that is
already pre
-
assembled in the [PWR] socket. To connect the supply lines,
it is recommended to remove the plug. The cable cores are connected
and screwed
according to the marking [+24 / GND].
RS485 Bias voltage The bias voltage for the RS485 interface is switched with the DIP
switches S1 and S2. The bias voltage is active when they are both set
to the ON position. The default setting for all DIP switches is OFF..
Notice
Switches S1 and S2 must always be switched together to avoid
transmission interference on the MS/TP bus.
RS485 Bias termination S3 provides a switchable 120 Ohm terminating resistor that terminates
the end of a segment in an MS/TP network. Termination may only be
done when the device is at the end of such a network segment.
