RS-485 Bus Overview When the communication distance is required to be from tens to thousands of meters, the RS-485 serial bus standard is widely used. RS-485 uses balanced transmission and differential reception, thus it has the ability to suppress common-mode interference. Additionally, the bus transceiver has high sensitivity and can detect voltages as low as … Read more
01 【Overview of RS-485】 RS-485, like RS-232, is a serial communication standard. The current standard name is TIA485/EIA-485-A, but it is commonly referred to as the RS-485 standard. RS-485 is widely used in industries such as automation, automotive, and building management. The RS-485 bus overcomes the shortcomings of RS-232’s short communication distance and low speed. … Read more
