Activate external devices through CAN data signal changes.
Our CAN-Bus Smart Trigger activates MDVRs, tachographs, emergency lights, and high beams in real time.
How the CAN Trigger works
The CAN-Bus Smart Trigger monitors vehicle CAN data in real time to detect specific signal changes. When a preset condition is met—like engaging reverse gear or reaching a certain speed—it instantly activates connected external devices. With support for both On/Off and Speed Pulse outputs, it offers flexible control for various automotive systems.
Factory-set parameters that will activate external devices
We have configured each output of the CAN-Bus Smart Trigger device with the following default factory settings. Please note that Pin 1 and Pin 6 serve as the power supply connections.
Pin 1: Ground connection
Pin 2: Right turn indicator (excluding hazard activation)
Pin 3: Parking brake status
Pin 4: Reverse gear engagement
Pin 5: Wheel-based vehicle speed
Pin 6: Ignition connection
Pin 7: Left turn indicator (excluding hazard activation)
Pin 8: Hazard warning lights
Pin 9: Ignition state
Pin 10: Brake pedal switch status
Key benefits
Direct compatibility – Outputs standard digital (On/Off) and pulse signals, ideal for cameras, relays, taximeters—no protocol conversion required.
Real-time response – Instant hardware-level signal output with zero parsing delay.
Fully configurable outputs – Each output line can be individually programmed to respond to specific CAN parameters (e.g., brake, indicator, reverse, speed).
Smart CAN decoding – Built-in firmware automatically detects and decodes CAN data from over 2,500 vehicle models.
Built-in measurement tool – Fast diagnostics and immediate functional feedback during installation or troubleshooting.
Continuously updated CAN Library – Firmware expands by 300–400 new vehicle models per year.
