RS-485 signal distributors may be used for star wiring. The maximum system cable length can also be
expanded by using these distributors, physically providing a new RS-485 bus with 1200 m cable length
each at every distributor output.
In case the maximum number of 32 bus participants is exceeded, the number of connected devices can
be increased by using RS-485 distributors. Each distributor output physically provides one RS-485 bus
which enables the additional connection of 31 further devices (the distributor output represents one bus
participant itself).
The maximum system expandability depends on the RS-485 address range of the installed devices.
Attention: The RS-485 signal distributor is unidirectional! This means that the signal only flows from
the input towards the outputs. Therefore, e.g. the interconnection of several EKB 500 keyboards is not
possible with this signal distributor!
