Functionality description
Pulse counter functionality enables devices to count digital impulses going to DIN1/DIN2/DIN4. This means that 3 digital inputs of the devices can be used with fuel flow meters, impulse frequency, and impulse RPM counter or other impulse-based accessories. Impulse-based fuel usage monitoring is much more accurate than different types of fuel metering sensors and it makes the devices a perfect solution for high-fuel usage machines like cranes, construction vehicles, mining machines, and agriculture equipment.
This functionality was added in 03.28.04.Rev.00 firmware version.

Warning! When the pulse counter is enabled, all other scenarios will ignore the corresponding DIN state, except DIN1 which can be used to wake up the device from Deep Sleep. |

System parameters description
If this function is active, then all other settings associated with the this input are disabled.
Frequency measurement can be performed in 2 different ways:
- Frequency is measured by counting pulses over time period (997 ms). Method is used for frequencies higher than 100 Hz.
- Frequency is measured by measuring time between pulses. Method is used for frequencies lower than 100 Hz.
Advanced Pulse Counter limitations
Advanced Pulse counter functionality has limitations when pulse is at different duty cycle and signal voltage at 2kHz frequency. Exceeding limitations might lead to unexpected pulse count or even stop functionality from working. Tables below shows those limitations for specific DIN.
Devices on DIN2 support up to 2kHz pulse frequency. Pulses can be with different duty cycles, but only pulses that are greater than 120μ period is counted, otherwise they are filtered as signal noise. In other words, pulse change between low and high state should not take longer than 120μ. Also, there is a pulse rise time that affects time when voltage threshold is reached. So, for 2kHz there is limitations for available duty cycle.

For lower than 2kHz frequencies smaller or bigger duty cycle might be available, considering previously mention conditions.
Also, devices that’s support 2kHz on DIN1 (see Table 1) have same limitations as DIN2, but also minimum voltage provided to DIN1 by pulse should be 7.5V or grater. Lower than 7.5V pulses add pulse rise time. For example, at 3.6V pulse rise time is ~500μ comparing to 7.5V at 60μ (FMB920). Pulse counting might work at these low voltages with low frequency but it is not reliable.
