Synchronous Communications

Typical synchronous communications

configuration (compatible with All Sensors

GA142 Series Digital Output Sensors).

Typical Configurations

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.
