    CAN segments, nothing else is required! When connected to a CAN bus system, a Kvaser Air Bridge device will by default determine the bit rate used by the attached CAN system using Automatic Baud Rate Detection (autobaud), see Section 3.6, Autobaud, on Page 12.

  • Page 10: Can Channel

    The recommended minimum distance between two Kvaser Air Bridge devices is 0.5 m. 3.2 CAN channel The Kvaser Air Bridge M12 has one CAN Hi-Speed channel with a 5-pin M12 Male CAN connector. See Section 4.3, CAN Connectors, on Page 16 for details about the pinout.

  • Page 11: Commissioning

    Kvaser Air Bridge ’one-to-any’ devices. All Kvaser Air Bridge ’one-to-any’ devices have the possibility of assuming on of two roles, i.e. acting as a Primary device or a Secondary device. By default, all Kvaser Air Bridge ’one-to-any’ devices are configured to be Secondary devices.

  • Page 12: Autobaud

    250 kbit/s 125 kbit/s The Autobaud Detection is done locally, so a Kvaser Air Bridge can be used to bridge two different CAN bus segments operating at different bit rates. However, the amount of traffic on the networks will determine whether the system designer should allow the networks to be bridged via the Kvaser Air Bridge.

  • Page 13: Optional Bit Rate Setting

    Kvaser Air Bridge System Integration Guide and the Kvaser Air Bridge Management Interface Description. Note that the bit rate setting relates to the CAN bus only, and that each Kvaser Air Bridge device therefore can be configured differently. 3.8 Optional custom CAN configuration The Kvaser Air Bridge ’one-to-any’...
