Can the RVVP cable be used as a 485 communication cable? What's the problem?
One experience is that if the communication distance is far away (such as more than 500 meters), you can connect a 120 ohm resistor at the far end and ensure the reliability of the communication.
There will be no negative issues. RS-485 is a good choice for using RVVP cable, which can make the shielding layer of the cable grounded.
