Wiring Notes:
⚫
The wiring of RS232B (port 1) is as above, the sending and receiving signals need to
be cross-connected, and it is recommended to use a double-female cross line when
connecting to a computer.
⚫
As above, the daisy chain topology is used for RS485 (port 2) 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 when there are
many slave stations.
⚫
Please be sure to connect the common terminal of each communication node to
prevent the communication chip from burning out.
⚫
Please use twisted-pair shielded cables, especially in harsh environments, and make
sure the shielding layer is fully grounded.

Cable Requirements:
Twisted pair shielded wire, and shielded cable grounded.
