How can noise be reduced on serial communication between two controllers. The earth/ground is not reliable.? - serial noise reduction 2.0f
Two controllers are in the serial communication. The driver uses VVVF AC drives, SMPS. We note that sometimes the driver picks up signals, do not expect.
The grounding is available on the website is not good.

Serial Noise Reduction 2.0f How Can Noise Be Reduced On Serial Communication Between Two Controllers. The Earth/ground Is Not Reliable.?

1) upgrade to a fiber optic link
Or
2) Use a differential signal technology, such as RS-442 or RS-485, not on devices that have the same field depend. Furthermore, differential signals to the modality of sound "common" could be induced in the cables from other sources in the region. Noise is true both + and -, signal cables at the same time, which tends to cancel.
Companies such as the black box to sell converter boxes, which may be useful that can meet their needs.
