4.3. Connection to the digital central unit

You can use

either the BiDiB interface (variant 1)

or the DCC-compliant interface (version 2)
for the connection of the B-6 to the central unit.
Preferred connection variant: BiDiB interface
If you use a digital control unit with BiDiB interface (e.g. MasterControl 2**), it is
recommended to use the BiDiB interface of the B-6 for the connection to the control unit. This
also applies if BiDiB is not used for the system control. The connection of the two devices via a
patch cable is easier to establish and permanently safer compared to the connection via the
DCC-compliant interface.

4.3.1. Connection variant 1: BiDiB interface (RJ 45)

!
Note:
RJ 45 connectors are also used for other data buses. Make sure that you plug the RJ 45
cable for connection to the BiDiB interface of the B-6 only into the BiDiB interface of your
central unit. If you plug the cable into an RJ 45 socket for another data bus, serious damage
may occur to one or both units.
Tip: To avoid confusion between different RJ 45 connections, it is recommended to use
different coloured cables for the different bus lines, e.g. green for the BiDi bus, blue for the
s88 bus, red for the data bus of the digital control.
Evaluation of short-circuit feedback signals
The B-6 sends a corresponding message via the BiDi bus in case of an overload at the track
output (e.g. in case of a short circuit). The digital control can react to this and e.g. switch off
the track voltage for the entire installation.
If the layout is controlled via PC with software that supports BiDiB, the software takes over the
so-called booster management. If the B-6 is only connected to the digital control unit via the
BiDiB interface, the digital control unit can react to short-circuit messages sent via the BiDi bus.
The prerequisite is that the central unit supports this function and is configured accordingly
(→ instructions for your digital central unit).
Connect one of the two BiDiB sockets of
the B-6 to the BiDiB interface of your
control unit via a RJ 45 cable. The two RJ
45 sockets of the BiDiB interface are
connected in parallel, so you can use any
socket.
