Asynchronous Communications
Typical asynchronous communications
configuration. The Mode pin is interrogated
at power up and if tied low, will cause the
sensor to enter asynchronous communica-
tions mode. This mode supports multiple
sensors by addressable commands. The
Convert/BR pin then serves to select one of
two available baud rates.
