FMB920 Features settings
When vehicle parameters exceed the values of Max Acceleration, Max Braking or Max Cornering parameters, the scenario is activated: a record is generated, and digital output status is changed to 1 when configured. You can configure all three parameters in m/s2 units. The scenario is activated until the current Acceleration, Braking, or Cornering value decreases below the set parameter value.
Parameters used with Eco/Green Driving functionality are given in a table below.
|Scenario Settings||Enable/Disable Green driving functionality|
|Max Acceleration||Value which can be reached while accelerating without triggering harsh acceleration event.|
|Max Braking Acceleration||Value which can be reached while braking without triggering harsh braking event.|
|Max Cornering Acceleration||Value which can be reached while cornering without triggering harsh cornering event.|
|Source||Which source (GPS or accelerometer) data will be collected from.|
|Eco/Green Driving Duration||If enabled, additional record with Eco/Green Driving event duration (ms) will be saved and send to server. When GPS is selected as the data source duration accuracy will be in seconds.|
|Output Control||Which FMB920 Digital Output will be used for accesory (buzzer, LED and etc.) activation/deactivation.|
|DOUT ON Duration||A value in miliseconds (ms), for how long DOUT should be active.|
|DOUT OFF Duration||A value in miliseconds (ms), for how long DOUT should be inactive.|
Data from accelerometer/GPS are continuously monitored and processed and are used to decide whether a harsh event has occurred. If either of three cases is satisfied, an event is generated and a record is saved and sent to the server (FMB920 must be properly configured in order to send the record). Event value is multiplied by 100 before sending/saving records to get more precision when displaying data.
The auto-calibration process is following:
- The vehicle is stopped.
- There is a straight road ahead.
- Send SMS "auto_calibrate:set" to the FMB device.
- Accelerate to >30 km/h for 5 sec.
- FMB will send a response when calibration is completed successfully.
Calibration is saved to internal flash memory, which means it will stay after a reset. To check auto-calibration status send a following short text message to the FMB device: "auto_calibrate:get".
When vehicle speed exceeds configured maximum speed value the scenario is activated, an event record is generated and digital output status is changed to 1 when configured.
Scenario is active until detected speed decreases below the set parameter value.
When a device detects GSM signal jamming, it activates the Jamming scenario. The device then starts a configurable timeout before responding that is intended to reduce false positives. After the timeout ends, the device generates an event record and digital output status is changed to 1 when configured If the device regains a GSM signal before the countdown ends, no event will be generated and output will not be controlled. This Digital Output activation can be used to trigger measures to disrupt potential thieves using GSM signal jamming to steal your vehicle.
Connecting a Buzzer to the Digital Output to emit sounds as soon as jamming is detected is the most straightforward use of this scenario.
The Digital Output can be directly connected to the vehicle's alarm system to ensure the thief can not avoid triggering it.
It can also be connected to the central lock system to ensure that all the doors are locked.
A relay can be used to disable the starter motor. Usually used with the Immobilizer scenario.
Alternatively, the Digital output can also be connected to an LED visible to the driver to inform the driver when Jamming occurs.
Eventual Records parameter can be configured: when it is disabled scenario status value will appear in each AVL record, otherwise, it will be appended only to eventual records.

DOUT Control Via Call
The scenario is activated and digital output is ON when a call is received from a number which is on the authorized numbers list.
Call control functionality is the following:
- When FMB920 is configured to control DOUT1/DOUT2 the device waits for an incoming call from a configured secure number. If a call is received FMB920 turns on DOUT1/DOUT2 for a user defined Duration Timeout. If duration timeout set to "0" DOUT1/DOUT2 will be OFF.
- DOUT1/DOUT2 can be turned off by Duration Timeout or by digital input 1, digital input 2 or digital input 3.
- DOUT1/DOUT2 will always be ON if, for example, DOUT deactivation is set to DIN1, but DIN1 will be never turned ON, or when duration timeout is set to maximum value (2147483647) which is about 68 years.
If DOUT Control is disabled, the scenario will only generate events without digital output activation. If DOUT Control is enabled DOUT1/DOUT2 turns ON if ignition turns ON (Ignition Source is configured to 1). After any iButton ID is attached, DOUT1/DOUT2 turns OFF. After iButton identification configured Ignition Source can be turned OFF (Ignition Source is configured to 0) for no longer than 30 seconds, otherwise, immobilizer must be repeated. If the iButton List Check parameter is enabled, the authorization will be successful only if the attached iButton is specified in the iButton list.
Ignition off timeout parameter is used to set the duration after which authorization is activated when the ignition is turned off. For example, if the Ignition off timeout is set to 30 seconds when the driver turns the ignition off, he has 30 seconds until the immobilizer security check turns on again. In other words, if the driver turns off the ignition and turns it back on in less than 30 seconds, then he will not have to attach the iButton to the reader again.
From the firmware version 03.25.14 iBeacon authentication was introduced. iBeacon authentication works in the same way as iButton authentication. To use authorized iBeacons, the iBeacon list should be filled in the device configurator. Instructions how to list iBeacons in FMB devices can be found here.
By using iBeacon authorization, the immobilizer feature can be used with devices that don't have a 1-wire data connection available.
GNSS Fuel Counter
- To configure Fuel Counter parameters use fuel consumption norms which are presented in the technical documentation of the vehicle. By default speeds for these fuel consumption norms are: City – 30 km/h, Average - 60 km/h, Highway - 90 km/h. These values can be changed.
- When speed is higher than the highway fuel consumption speed, x% of highway fuel consumption is added every extra y km/h, by default FMB920 adds 20% every 50 km/h of extra speed. For example, the fuel consumption is (1.2 * (Highway Fuel Consumption)) at 140 km/h and (1.4 * (Highway Fuel Consumption)) at 190 km/h.
- Correction coefficient is used to correct every value of fuel consumption which is sent to the server through an expression of ((Used Fuel) * Correction coefficient). By default, it is 1, with minimum and maximum values of accordingly 0.01 and 2. For example, when the correction coefficient is 1 and FMB920 calculates that the amount of used fuel over 35 m distance is 20 ml, the value of 20 ml will be sent to the server, and if correction coefficient is 1.2, the value of 20 * 1.2 = 24 ml will be sent to the server.
- Fuel Consumption on Idling is used to calculate fuel consumption when the ignition is on, but the vehicle is stationary. The consumption value is 1 l/h by default, with a minimum and maximum of accordingly 0 and 5 l/h. This parameter is less than 1.0 l/h for almost all diesel cars and is equal to about 1.5 – 2.0 l/h for gasoline cars.
DOUT Control Via Ignition
This feature allows direct control of DOUT by configured ignition source status. When enabled, the function will start to monitor ignition status, and once the ignition changes state from On to Off after configured Ignition Off a timeout, selected DOUT (Digital Output) will be turned On.
Turning DOUT Off is possible with enough voltage applied to the configured DIN (Digital Input). Voltage requirements: DIN1 – 7.5V, DIN2-4 – 2.5V.
|DOUT Control via Ignition Scenario||Enable/Disable DOUT Control Via Ignition scenario|
|DOUT Control||Scenario controls configured DOUT if ignition timeout exceeds its limit|
|DOUT Deactivation Via DIN||DOUT is turned off if configured DIN is in on (voltage applied) state|
|Ignition Off timeout||Duration (in seconds) after which DOUT is turned on, when ignition is turned off|
Ignition ON Counter
It is possible to configure a starting value of the counter. Maximum value: 2147483647 seconds or 596523.235 hours NOTE THAT, when entering a starting value, the value must be in seconds!
