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.

RS485 to USB adapters serve the purpose of connecting RS485 compatible devices to the USB port of a computer. In certain industrial tasks or for the sake of networked information retrieval, RS485 equipped sensors or controllers need to be integrated with a computer for its configuration, monitoring or data uploading functions. The USB port cannot understand the RS485 serial signals, and with the help of an RS485 to USB adapter, these signals can be transformed so that the computer's USB port can understand them. This makes it easier to connect RS485 compatible devices to modern computers that, instead of featuring native RS485 ports, come equipped with USB interfaces. This feature makes it easier for computers to be integrated with RS485 devices and makes it simpler to turn a computer into a controller for RS485 enabled systems.

What is RS485 used for?

RS485 is a serial communication standard used in industrial automation, security monitoring, and other fields. It enables long - distance communication between multiple devices in these applications.
RS485 is more suitable for medium - speed data transfer. While it can support data rates up to a few Mbps, it is not as fast as some other high - speed communication standards. But its reliability and long - distance capabilities make it ideal for industrial applications.
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.
