Wiring Notes:
⚫
As above, the daisy chain topology is used for wiring, so the star topology cannot be
used. When the use environment is ideal and there are few nodes, the branch
structure can also be considered.
⚫
Please connect a 120Ω terminal resistor in parallel at the two ends of the CAN bus to
match the circuit impedance and ensure communication stability.
⚫
Please be sure to connect the common terminal of each node on the CAN bus to
prevent the CAN chip from burning out.
⚫
Please use twisted-pair shielded wires, especially in harsh environments, make sure
the shielding layer is fully grounded.
⚫
On-site wiring should also pay attention to the distance between strong current and
