ERS-4 Instruction Manual
A RS-485 distributor can also be used to increase the maximum number of devices on the bus as well as
the total range. Each distributor output provides another RS-485 bus. This allows each output to extend an
additional 1200m, and it also enables the additional connection of 31 further devices to each output (the
output itself represents one device).
The maximum system expandability depends on the RS-485 address range of the installed devices.
System expansion with RS-485 signal distributor
ATTENTION: Most signal distributors are unidirectional! This means that the signal only flows from the
input towards the outputs. Therefore, e.g. the interconnection of several keyboards is not possible with
these types of signal distributor!
