similar interface. The DSI485A module is used, for example, for
connecting displays and terminals to the data logger when the distance
is longer than 15 meters. The maximum distance for DSI485A is
approximately 1500 meters at full speed. The DSI485A module must be
configured before using it in order to work as desired.
