DSI485A
The DSI485A communication module can be configured for either 2-
wire line or for 4-wire line when 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 a default mode.
