RS485: Serial Communication Standard for Industrial Applications

RS485 is a serial communication standard often used in industrial automation, security monitoring, and other fields for long - distance communication between multiple devices. Using differential signal transmission, it has strong anti - interference ability and long transmission distance, and can support multiple devices to communicate on one bus for distributed control systems.

Advantages of the product

Strong Anti - interference Ability

The differential signal transmission used by RS485 provides strong resistance to electromagnetic interference. This allows it to operate reliably in environments with high levels of electrical noise, ensuring stable data transmission in industrial settings.

Simple and Cost - effective

RS485 is a relatively simple and cost - effective communication standard. It requires less complex hardware and cabling compared to some other communication protocols, making it an attractive option for applications with budget constraints.

RS422 is a type of serial communication standard. This type of communication uses differential signaling which has less noise and allows for longer travel distance than some other standards. It is common practice to use RS422 in industrial and automated settings for point to point communication. For example, in a factory, RS422 is useful for linking a PLC to remote sensors or actuators because data is reliably transferred over great distances. Moreover, certain scientific and medical devices can use it to communicate between parts that require precise and sequential free communication.

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.
