the branch structure also can be used.
⚫
Please connect a 120Ω terminal resistor in parallel to each end of the CAN bus for
matching the circuit impedance and ensuring communication stability (when it is one
to one connection and the number of slave station is less and the wiring is short,
terminal resistor can not be added).
⚫
When the number of slave station is more, p lease connect a 120Ω terminal resistor
in parallel to each end of the RS485 for matching the circuit impedance and
preventing signal reflection.
⚫
Please be sure to connect the public ends of each node on the CAN bus / RS485 to
prevent the CAN / RS485 chip from burning out.
⚫
Please use STP (Shielded Twisted Pair), especially in bad environments, and make
sure the shielding layer is fully grounded.
⚫
When on-site wiring, pay attention to make the distance between strong current and
weak current, it is recommended for the distance to be more than 20cm.
⚫
It should be noted that the equipment grounding (chassis) on the entire line must be
good, and the grounding of the chassis should be connected to the standard factory
ground pile.
⚫
Please wire according to wiring, don’t connect to all controllers’ EGND signals.

Cable Requirements:
Shielded Twisted Pair, and the shielded cable is grounded.
