Isolated RS-485 Module DSI485
The isolated RS-485 communication module can be configured either
for a 2-wire line or for a 4-wire line when the receive and transmit lines
are separated. If the module is configured for a 2-wire line, the
transmitter is enabled only during the transmission. Normally, the 2-
wire connection is used to connect several devices to the same
communication line. The 4-wire mode is the default mode.
