Some types of sensors have additional properties described below.
The possibility of indicating filtration level is applicable to the following sensors: temperature sensor, engine revs sensor, voltage sensor, accelerometer, custom sensor, weight sensor. This option allows applying the smoothing algorithm to the sensor values. It is necessary to indicate the level of such smoothing (from 0 to 255) in the corresponding field. The filtration level is indicated individually for the sensors of such a type.
The filtration level is only taken into account in reports (in tables and in charts while drawing smoothed lines).
This property is a specific feature for the engine ignition sensor and the custom digital sensor. Indicate the time value (in seconds). If nothing is indicated in the field or 0 is entered, the option is considered to be disabled. If the time between messages exceeds the time indicated by you, then the time interval at which the timeout has been exceeded is considered invalid, and the remaining time is divided into intervals (before and after the invalid time period). In other words, the last message before, and the first message after the invalid time period are considered the end of the first and the beginning of the second interval, correspondingly.
A one-hour timeout is indicated for a custom digital sensor. The following data comes from the sensor: 1 (22:00), 1 (22:10), 1 (07:50), and 1 (08:00). If the timeout property had not been indicated, we would have had one continuous interval (from 22:00 to 08:00). But using 1 hour timeout we receive the following situation: there is less than 1 hour between the 1st and 2nd message, so we have the first interval (from 22:00 to 22:10); between the 2nd and 3rd messages more than 1 hour passes, so this data is considered to be an invalid time period (from 22:10 to 07:50); and there is less than an hour between the 3rd and 4th message, so we receive the second interval (from 07:50 to 08:00).
This option is used to calculate fuel consumption mathematically for the sensors of the Engine ignition, Absolute engine hours and Relative engine hours types.
If the ignition is off, the consumption is considered to be 0 l/h.
The option is available for an ignition sensor, relative and absolute engine hours and allows binding the engine efficiency sensors of the unit to them. Once bound, the values of these sensors are taken into account when calculating fuel consumption. Select the sensor or sensors you want to bind. To select all the sensors at once, press Ctrl and click on any of them. If no sensor is selected, the calculation is carried out taking into account all the sensors of the appropriate type created for the unit.

This option is available for an impulse fuel consumption sensor, absolute fuel consumption sensor, instant fuel consumption sensor, and a fuel level sensor. If the option is enabled, the data calculated by the sensor is included in the Consumed row in statistics. Below, you can learn how fuel consumption is calculated by each of these sensors.
Impulse fuel consumption sensor
When fuel consumption is calculated by this sensor, its values from the previous and current messages are taken into account. The previous value is subtracted from the current one and, if needed, the calculation table is applied to the resulting value. The sum of the values received on the interval corresponds to the amount of the fuel consumed.
For calculating fuel consumption, a sensor of this type should have a calculation table from impulses to liters (gallons).
Absolute fuel consumption sensor
This sensor shows the fuel consumption during all the period of vehicle operation. The AbsFCS values increase all the time, so an overflow of such a sensor is not expected.
The fuel consumption is calculated by this sensor in the following way: the sensor value at the beginning of the interval is subtracted from the sensor value at the end of the interval and, if needed, the calculation table is applied.
Instant fuel consumption sensor
If this type of sensor is used, the hardware sends messages that contain the amount of the fuel consumed from the previous message till the current one. Accordingly, to determine the fuel consumption on an interval, the values of the InsFCS are summed.
For instance, the hardware has sent three messages with the following values: х1 = 0,01 l, х2 = 0,023 l, х3 = 0,048 l. The fuel consumption during this interval is: х1 + х2 + х3 = 0,01 + 0,023 + 0,048 = 0,081 (l).
Fuel level sensor
The calculation of fuel consumption on the basis of the fuel level sensor is described here.
This option is displayed for impulse fuel consumption sensors and becomes available when the Calculate fuel consumption by sensor option is enabled. If there is a limit after which the impulse counter is zeroed (overflow), you can indicate it in this field. The value should be integer and greater than or equal to zero. However, with the limit indicated in case of an emergency reset, the calculations will be meaningless. In this case, the specified limit should be equal to zero.
This option is displayed for impulse fuel consumption sensors and becomes available when the Calculate fuel consumption by sensor option is enabled. If the Skip first zero value option is activated and the value of the Max impulses field is 0, the difference between the current and previous sensor values is taken into account when calculating the fuel consumption. If the value of the Max impulses field is nonzero, the Skip first zero value option is not taken into account when calculating the fuel consumption.
This option is available for the sensors that can be influenced by occasional resets (mileage sensor, absolute engine hours, absolute fuel consumption sensor). When this option is enabled, the system uses the following algorithm. The value from the latest message is compared to the previous one. If the value is greater than the previous one, their difference is added to the previous value. If it is less, the value from the latest message is added. This algorithm ensures that the resets are taken into account and correct data is obtained.
This option appears only for the differential counter sensors with overflow. If it is activated, raw data is analyzed first, and then the calculation table is applied. It means that raw data (and not data processed with the calculation table, as it is in the case when the option is disabled) is taken to estimate overflow.
This property is specified for sensors of driver/trailer binding. If the option is activated, the driver bound to the unit can be unbound from it automatically only if the empty value comes from the same sensor that was used to bind the driver. Otherwise, the unbinding of the driver on any sensor results in the unbinding of all drivers bound to this unit. The same is for the trailers.
This property is also applicable to the driver/trailer assignment sensors. You can type a custom code in the Separation code field. If the code is specified, the driver/trailer separation is carried out when the empty value or the code is received.
This option is relevant for the digital sensor of the Private mode type. Its activation allows hiding the information about the unit location in the monitoring panel, on the map, in reports, tracks, etc. in case a private mode trip is detected. This is applied only to the messages which are received from the unit after you activate the option. Next to the caption of such a unit, on the map and in the monitoring panel, the icon is displayed and the last known location is shown instead of the current one.
When using this option, it is recommended to enable the display of the unit caption on the map.
This option is available only for custom sensors. It should be activated if the sensor sends text parameters instead of numeric. In this case, in the table of intervals and colors, you can list these parameters and give them broader descriptions. For example, a device sends parameters error1, error2, error3, etc. In accordance with the documentation for the device, you can specify decryption for each parameter (i.e. Power supply disconnected, Invalid data, etc.). Besides, you can use the special character * (asterisk) which substitutes for any combination of characters. For example, you can indicate that the value error* should be always displayed as Error.
