L W Bus Topologies
ON ORKS
The L W Bus is a 78-kilobit serial link that uses
ON ORKS
transformer isolation so that the bus wiring does not have a
polarity. I.e. it is not important which of the two L
Bus terminals are connected to each wire of the twisted pair.
The L W Bus does not need to be shielded on the
ON ORKS
controller module side.
The L W Bus can be wired in daisy chain, star, loop
ON ORKS
or any combination thereof as long as the maximum wire
length requirements are met.
Configuration
The recommended configuration is a daisy chain with two
bus terminations. This layout allows for max. L
Bus lengths, and its simple structure presents the least
number of possible problems, particularly when adding on to
an existing bus.

C-Bus Topologies

Via the C-Bus up to 30 C-Bus devices (e.g., controllers, etc.)
can communicate with one another and a PC central. The
C-Bus must be connected via the individual controllers
(open ring).
Note
Star connection is not allowed because uncontrollable line
reflections may occur.
Instead of an Excel 800 Controllers, other C-Bus controllers
(e.g., the Excel 500, Excel 100, Excel 50) can also be
connected.
