INPUTS
Vega MT-5 CAN GNSS tracker has three multifunctional inputs that can operate in four modes:
Analog;
Digital;
Frequency;
Pulse.
In analog mode, the input voltage is measured. Such an input can be used for sensors whose readings
vary in a certain range.
In digital mode, the input signal level (0 or 1) is measured. Such an input can be used for logic sensors,
the readings of which are determined by two states (on/off).
In frequency mode, the frequency of the pulse signal is measured. Such an input, for example, is
convenient to use for a car tachometer.
In pulse mode, the number of pulses at the input is counted. Such an input can be used for flow rate
sensors, for example, fuel consumption.
In the settings of multifunctional inputs in the “Configurator” program, in addition to selecting a mode
for each input, there is a parameter called “Active Level”. It can take the value “low” and “high” and
characterizes the magnitude and direction of the input tightening.

Pull-up to external power cannot be carried out while battery powered device
When the device is restarted, the multifunction input is pulled to the ground
