RS-485 Bus cabling
If the remote devices are properly installed, all the bus communication LEDs featured on each device should flash. If any of them are
not flashing it means that the device has not been correctly installed and programmed (check wiring, address and programming in control unit).
TRADITIONAL CABLING (INPUT - OUTPUT)
BRANCHED-OUT CABLING
Branching out 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 it is noticed that the structure of the RS-485 bus is still linear (input-output).
