  • Organization

    • Log files grouped by session (power cycle)

    • Log files split based on file configurable size or time

    • Optional cyclic-logging mode (oldest log file is deleted when memory is full)

  • Performance

    • Simultaneous logging from 2 x CAN-bus + 2 x LIN-bus

    • Message time stamping with 50 us resolution

    • High message rate[1]

    • Optional data compression (LZSS)

  • Security

    • Globally unique device ID with customizable device name

    • Power safe (device can be disconnected during operation without risk of data corruption)

    • Optional end-2-end data encryption (AES128-GCM)

Real-time clock (RTC)

  • High precision real-time clock retains date and time when device is off

  • The real-time clock can be automatically synced from various sources[2]

CAN-bus (x2)

  • Physical

    • Two physical CAN-bus interfaces

    • Compliant with CAN Protocol Version 2.0 Part A, B and ISO 11898-1

    • Compliant with ISO CAN FD and Bosch CAN FD

    • Ideal passive behavior when unpowered (high impedance / no load)

    • Short circuit protection

    • Transient protection

    • TXD dominant timeout (prevents network blocking in the event of a failure)

    • Data rates up to 5Mbps[3]

  • Controller

    • Based on MCAN IP from Bosch

    • Bit-rate: Auto-detect (from list[4]), manual simple (from list[5]) or advanced (bit-timing)

    • 128 standard CAN ID + 64 extended CAN ID filters (per interface)

    • Advanced filter configuration: Range, mask, acceptance, rejection

    • Configurable transmit messages, single shot or periodic (up to 128/64 regular/extended)

    • Message down-sampling based on:

      • Count

      • Time

      • Change in data

    • Support for Remote-Transmission-Request (RTR) frames

    • Silent modes: Restricted (acknowledge only) or monitoring (transmission disabled)

    • Supports all CAN based protocols (J1939, CANopen, OBD2, NMEA 2000, …)[6]

    • Application

      • Cross-channel control-message for start/stop of reception/transmission

      • Heartbeat-message to broadcast device time, space left on SD-card and reception/transmission state

LIN-bus (x2)

  • Physical

    • Two physical LIN-bus interfaces

    • Industry standard DB9 (D-sub9) connectors

    • No internal diode and resistor for publishing mode
