Virtual Ignition
Detect engine status by battery voltage
System that automatically detects if the engine is on or off by analyzing battery voltage. Ideal for installations where connecting to the physical ignition line is not possible.
Voltage Detection
Alternator vs Battery
Engine Off
12.0V - 13.0V
Engine On
14.0V - 14.8V
How does it work?
When the engine is running, the alternator generates additional voltage that raises battery voltage. By leveraging this difference, we can detect engine status without additional wiring.
Engine Off
12.0V - 13.0V
Battery only, no alternator charge
Engine On
14.0V - 14.8V
Alternator charging the battery
Hysteresis
~1.4V
Prevents false oscillations between states
Simplified Installation
No need to find or connect to the vehicle's ignition wire.
Universal
Works with any 12V or 24V vehicle - cars, trucks, or machinery.
No Extra Wiring
The device already measures supply voltage, just enable the feature.
Configurable Thresholds
Adjust voltage values according to each vehicle's characteristics.
Three available modes
The CXIGN command allows you to choose how the device determines ignition status.
Physical Input
Normal mode. Reads status from the device's physical ignition input.
Manual
Allows setting IGN status manually with the SS command. Ideal for testing.
By Voltage
Automatically detects engine ON/OFF based on main supply voltage.
Virtual Ignition with Event Engine
For more control, you can configure custom thresholds using analog ranges (AR) and event engine rules.
Manual Mode
>SCXIGN1<Sets ignition to manual mode to control it via software.
High Threshold (Engine ON)
>SAR0407+1450+9999020<Sets AR04 range between 14.50V and 99.99V. When voltage enters this range, engine is running.
Low Threshold (Engine OFF)
>SAR0507+0000+1310020<Sets AR05 range between 0 and 13.10V. When voltage enters this range, engine is off.
IGN = 1 Rule
>SRLA0E;TRG=AR04+;ACC={SSSIGN11}<When voltage enters AR04 range (exceeds 14.5V), set IGN = 1.
IGN = 0 Rule
>SRLA1E;TRG=AR05+;ACC={SSSIGN00}<When AR05 deactivates (low voltage), set IGN = 0.
Complete Script
Copy and send these commands to configure virtual ignition:
>SCXIGN1<
>SAR0407+1450+9999020<
>SAR0507+0000+1310020<
>SRLA0E;TRG=AR04+;ACC={SSSIGN11}<
>SRLA1E;TRG=AR05+;ACC={SSSIGN00}<Recommended values
Thresholds may vary by vehicle type. We recommend measuring actual voltage before configuring.
12V Automobiles
Cars, pickup trucks, motorcycles
24V Trucks
Trucks, buses, heavy machinery
Special Machinery
Harvesters, tractors, equipment
Values may vary depending on battery condition and vehicle electrical system.
Where is it used?
Virtual ignition is especially useful in installations where wiring access is difficult.
Rent a Car
Quick installations in rental fleets without accessing original wiring.
Leasing & Finance
Discreet installations that don't modify the vehicle's electrical system.
Heavy Machinery
Equipment where finding the ignition line is complex or impossible.
Portable Devices
OBD2 or magnetic devices without physical ignition connection.
Simplify your installations
Virtual ignition is available on all our devices at no additional cost.
