The communication protocol is the same (see the structure below),
but only the RS 485 manages the address field. Therefore to enable
the RS 485 is necessary to select the type of communication as well
as the device address by means of the T-plus software.
The RS-485 is a 2-wire (gnd optional) half-duplex communication link.
