ADAS
Advanced Driver Assistance Systems
Syrus can interact with Advanced Driver-Assistance Systems accessories which help monitor the road to help avoid collisions & accidents. ADAS accessories notify when a vehicle is close to hitting the vehicle or pedestrian in front of it, including alerts for when the vehicle is swerving on the road without directional signals.
General Overview
- Use the apx-ecu tool to configure the ECU with the compatible ADAS accessory
- Add the ADAS accessory's parameters to the ecu monitor configuration file
- Connect the ADAS accessory to the Syrus
- Install the ADAS accessory in a vehicle
- Receive alerts and information from the ADAS accessory

Installing a Terminating Resistor
Note that the impedance of the CAN bus must be 60 Ohms. To measure the impedance turn off the vehicle and make sure the multimeter is set to measure resistance (20Ω scale), and finally place the red and black probes on the CAN bus, it should be around 60Ω.
When connecting a single Movon device to the CAN bus the impedance of the bus changes to 120Ω, in order to drop it to the required 60Ω value a 120Ω resistor must be placed in parallel at the terminating end of the CAN bus wires of the Syrus 4G CAN High/CAN Low wires.
Any value lower than 60 Ohm indicates that there are probably more than two 120 Ohm bus termination resistors present. A value bigger than 60 Ohm typically indicates that there is at least one bus termination resistor missing or the bus terminators have a wrong resistance value.
Note: If you connect multiple accessories with terminating resistors, for example 2 Movon sensors, the impedance will measure out to be 60 Ohms, meaning you DO NOT have to add a resistor in this case.
The recommended resistances wattage depends on the type of vehicle, for 12V use at least a wattage of 0.5W, and for 24V use a wattage of at least 1W.
