ISO 11783 Physical Layer

• Bus Fault Tolerance:

  • Continued communications (emissions failure?)
    • CAN_H shorted to Vbat or Ground or interrupted
    • CAN-L shorted to Vbat or Ground or interrupted
  • Communications Failure
    • CAN_H Shorted to CAN_L
    • Terminator power interrupted

• Termination: High impedance at nodes

  • Active terminators - precise differential current control
