CANBus Communications

 

Modules CB1, CB2, and CB3

Modules CB1, CB2, and CB3 are NAI’s latest generation 8 channel CANBus Communication Modules. These sophisticated serial bus system modules are used on our multifunction embedded boards and SBCs.

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 CB1 module stack supports CAN 2.0 A and B protocol. Each channel is independently configurable.

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.

The CB3 module stack design supports both CANBus 2.0 A and B protocol and CANBus SAE J1939 protocol. Each channel can be set for either protocol.

Features:

  • 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
