Section 2. Installation
Please refer to the documentation for your CAN network to check the preferred
method of connection. For many applications various standards will apply giving
recommended practises for connection. Apart from the choice of connector some
standards recommend different ways of ‘tapping’ into CAN networks and also
recommend maximum lengths for ‘T’s or ‘stubs’ off the network. For instance, at
the highest baud rate of 1Mbit/s, ISO11898 recommends a maximum bus length
of 40 m and a maximum stub length of 0.3 m. These lengths increase significantly
at lower bit rates.
As discussed above you also need to consider:
• If the SDM-CAN should terminate the network
• If it should be configured in isolated mode
• If transmission should be enabled
• The source of power for the isolation hardware.
