在进行RS485通讯连接时，建议采用屏蔽双绞线，每芯截面至少为0.5mm2，分别连接A、B端，并确保屏蔽层可靠接地。布线过程中应避免将通讯线与强电电缆或其他强电场环境并行，以减少电磁干扰，保证通信的稳定性。
The recommended communication connection utilizes a three-core shielded cable, with each core having a cross-sectional area of no less than 0.5mm², connected to A and B respectively, and the shielding layer grounded. The wiring should be kept away from strong cables or other strong electric field environment.
