The main differences between RS-232 and RS-485 are: 1. The transmission methods are different. RS-232 uses an unbalanced transmission method, known as single-ended communication. In contrast, RS-485 uses balanced transmission, which is a differential transmission method. 2. The transmission distances are different. RS-232 is suitable for communication between local devices, with a transmission distance generally … Read more

Serial Communication refers to a communication method for data transmission through serial ports. Data is transmitted bit by bit through data signal lines and ground lines. Common serial ports include RS-232, RS-485, and RS-422. It is important to note that serial ports are only interface standards, specifying the electrical standards of the interface, and not … Read more

Any form of communication requires rules to ensure everyone is on the same page. In electronics, these rules take the form of standardsāthese 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
Communication issues, just like traffic problems, can have various situations such as high-speed, low-speed, congestion, interruptions, etc. If we compare serial communication to traffic, UART can be likened to a station, while a frame of data is similar to a car. Cars on the road must obey traffic rules. In urban areas, speed limits are … Read more
