3) The EIA standard establishes that by RS-485 interface it is possible
to connect up to 30 devices with one remote master unit.
The serial interface of these instruments is based on “High
input impedance” transceivers; this solution allows you to
connect up to 127 devices (based on the same transceiver
type) with one remote master unit.
