RS 232/RS 485 Communication Description

Both the RS 232 and the RS 485 interfaces are available on the
connector J2.
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 software.
