CABLING WITH BRANCHING
The branching consists of a cable with three pairs, two
of which are twisted (each pair is made up of conductors A and
B) Analysing the circuit made in this way, you can see that the
structure of the RS-485 bus is still linear (entry-exit)

Device on bus
If the installation of remote devices has been carried out
correctly, all the bus communication LEDs on each device should
flash If some of them don't flash, it means that the device has not
been installed and programmed correctly (check cabling, address
and programming in the control unit)
