In fact, We only have a normal wired cable . I can not use any other wires. Wireless is not responsive Is there a way? The main problem is the current induction And loss of connection i try RS485 & CanBus But none worked or worked very poorly Thanks in advance

Lamp cord? And, again, what is your data rate? And RS-485 is good for 1200 meters. Your cable must be pretty low quality.
