8 CANBus Channels, J1939 Protocol

The serial bus system with real-time capabilities is the subject of the ISO 11898 International Standard and covers the lowest two layers of the ISO/OSI Reference Model. Our CANBus modules provide independent, isolated channels of CAN serial data bus links, conforming to the ISO 11898 International Standard. All CAN nodes are able to transmit data and several CAN nodes can request the bus simultaneously.

The CB2 module stack design conforms to the SAE J1939 protocol specification with address claiming option: Transport and DataLink layers IAW SAE, Section J1939/21.

  • Eight independent, galvanically-isolated channels implemented with Bosch® FPGA core
  • Fully compliant ANSI C network: Transport and DataLink layers
  • Addressing settings: self-configurable, non-configurable, or command-configurable
  • Adjustable baud rate with speeds up to 1 Mbit/sec
  • MilCAN compliant (CB1 CAN 2.0 base foundation with higher level protocol integration-ready)
  • Continuous Background Built-in-Test (BIT) status for real-time channel health
  • Error status registers
  • Self-test mode

  • Number of Channels: 8 Rx/Tx Channels
  • CAN Protocol: Version SAE J1939
  • Data Rate: Up to 1 Mbps per channel.
  • Data Length: 0-250 bytes
  • Power: 210 mA @ 5 V per channel typical
  • Weight: 1.5 oz. (42 g)
