Watchport/D (Proximity & Distance Sensor)
The Watchport/D can be programmed to use either an RS-232 modem signal interface or an
ASCII command interface. In its ASCII command mode, the sensor reports the distance to the
object (if any). In its modem signal mode, the sensor acts as a 'proximity' detector; that is, if an
object comes within range, the sensor will raise (and then lower) its DSR signal. The default
mode is Proximity.
