OUT 1 & OUT 2
The OUT1 and OUT2 connectors each have 1 analogue voltage and 1 digital output. The digital output on connector OUT1 is a frequency/pulse output
corresponding to velocity. The pulse per meter range is adjustable in software. The digital output on connector OUT2 is a simple on/off state output. This
digital output can be associated with any of the data channels being logged by the VBOX. A threshold level can be set for the selected data channel where a
true condition gives a 5v output and a false condition gives a 0v.
i.e. Data channel
–Speed, threshold 40Km/h. When speed is >40 output = 5V, speed ,40 output = 0V
A hysteresis and tolerance value can also be associated to this condition.
The default function of this digital output is to indicate the current logging status of the VBOX.
The analogue outputs on connectors OUT1 and OUT2 are both user configurable. For example, analogue output 1 could be configured to output velocity
while analogue output 2 might be configured to output lateral acceleration. The voltage range of both analogue outputs is 0 to 5v DC.
