Serial Mode
Overview
You can use any computer or data logger that has a serial port to collect
the sensor data by using the serial commands. The communication speed,
parity, and number of data bits for the serial line can be selected by the
user. The sensor can be set to transmit data messages at predefined
intervals (autosending) or it responds to a polling string, which is specific
to a selected output message format. Various operational parameters can
be set through a terminal connection.
NOTE Since the serial line settings may not be known for a device, the settings
are held as constant for the first five seconds after powering up the
sensor. During this time, the sensor responds to commands issued with
settings such as 9600 bit/s, 8 data bits, parity None, 1 stop bit.
