Please use shielded twisted-pair wire as CAT5E or above, connect to metal shell of network interface to ensure EMC performance.
The distribution length of communication cable shall be less than 100m;
The master communication port is connected to CN3(IN), and CN4(OUT) is connected to the next slave device. If the cables were incorrectly connected, the communication would fail.
