NOTE
In the interconnection of the 485 network, to attend the EMC standard (Electromagnetic capability), it is
necessary to use a 3-wire shielded twisted pair cable. Where, two wires are used to communication and
the third is used as reference. The shielding must be connected in one of the housing endings.
