Any form of communication requires rules to ensure everyone is on the same page. In electronics, these rules take the form of standards—these are widely applicable design specifications recommended by industry associations. Following these guidelines helps engineering devices speak the same electronic language, enabling efficient and reliable communication. RS-232 (“RS” stands for “Recommended Standard”) was … 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
