IMSA Accident Data Recorder V2 (ADR2)

Features: Configurable thresholds to trigger an event - password-protected feature. Configurable thresholds to trigger the medical light output - password-protected feature. Support for external medical and status lights. CAN and GPS inputs for data recording. Internal backup power to continue recording if power is lost. Real-time clock for accurate time keeping. Password protection restricts selected features to ISMA access only. Communications: CAN for transmitting and receiving ISMA-specified data. RS232 for receiving GPS data. USB for communication with ADR2 Manager. Connectors: 1 x 13 pin Autosport connector size 10. Physical construction and dimensions: Case size: 86 mm x 45 mm x 25 mm. Case material: anodized aluminum. Ingress protection rating: IP66 / IP67. Operating temperature: -40 to 85 °C. Weight: 130 g. Power: Power supply: 6 – 32 V. Current: nominal 200 mA @ 12 V (with external GPS), maximum 1 A when charging backup power supply. USB power when connected to PC (when no other power source is connected). Backup power supply. Provides power for at least 45 seconds of continuous recording after vehicle power is lost. Recharges in less than one minute after vehicle power is applied. Medical and status light outputs: Topology: current limited open collector high-side drive. External load: LED to GND or logic level input with a pull-down resistor. Voltage on: 5 V – Regulated. Voltage off: 0.3 V (with external 10k load to ground). Voltage off: 2 V (approximately, when not connected). Current Limit: 20 mA. Reverse polarity protected. Voltage diagnostic feedback. Operational: Recording of lateral, longitudinal, and vertical accelerations at 3000 Hz. Recording of CFC60 filtered acceleration data at 1000 Hz. Acceleration channel resolution: 0.125G. Recording of ISMA-specified CAN channel. GPS data recorded: Date and Time. Latitude and Longitude. Accelerometers range: -480G to +480G. Accelerometers overload: 1800G minimum. Pre-event recording: 15 seconds. Total event recording: minimum 30 seconds, extended on the subsequent impact. Data output format: CSV.
