Synchronous Timing Diagram (Note: Asynchronous mode timing is per RS-232. To use RS-232 requires the Maxim MA232
interface circuit for proper voltage level compatibility.)

Typical Configurations
Synchronous Communications
Typical synchronous communications
configuration (compatible with All Sensors
GA142 Series Digital Output Sensors).

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.
