SIGNAL DESCRIPTIONS
Vs and GND (Power): Red and Black wires respectively for the
2240-CAB cable (ordered separately). Power (+9 to +32 Volts
DC) and ground.
AOP and AON (Output): Green and White wires respectively for
the 2240-CAB cable (sold separately). Analog output voltages
proportional to acceleration; AOP voltage increases (AON
decreases) with positive acceleration. At zero acceleration both
outputs are nominally equal to 2.5 volts. The device experiences
positive (+1g) acceleration with its lid facing up in the Earth’s
gravitational field. Either output can be used individually or the
outputs can be used differentially. (See response plot below).
