What are the advantages of RS485?

RS485 has advantages like strong anti - interference ability due to differential signal transmission, long - distance communication capability, and the ability to support multiple devices on a single bus for distributed control systems.
Typically, an RS485 bus can support up to 32 devices. However, with the use of repeaters or special drivers, the number of connected devices can be increased, depending on the specific application requirements.
In an RS485 network, devices are daisy - chained together using two wires (A and B). The positive terminal of one device is connected to the positive terminal of the next device, and the negative to the negative, following a proper grounding scheme for stable operation.
