Analog voltage output
The analog voltage interface on the “Vout” screw terminal produces a linear voltage of between 0.0 V and 3.3 V that is proportional
to the measured distance. The actual distances of the 0.0 V and 3.3 V end points can be adjusted through the menu system. The
analog voltage can be measured by the host controller using any available analog-to-digital-converter (ADC). The voltage is updated
32 times per second and has 10 bit resolution.

Alarm outputs
The alarm output on the “Alarm1” screw terminal is a digital warning signal that becomes active when an object is closer than a
preset distance. The alarm distance can be set using the menu system. The alarm is active high with an output of 3.3 V. This alarm
signal can be connected to an available digital port pin on the host controller and read as: low = safe and high = alarm.

There are two additional alarms available on the digital expansion port (see “Digital expansion port” on page 9) and all three alarms
give a visible LED indication when active.
