Rs232 function
WebThe RS-232 standard requires signal levels of +5V (minimum) for a low and -5V (minimum) for a high. A higher voltage swing ensures greater noise immunity after the signals travel through lossy cables to RS-232 receivers. Early RS-232 transceivers (such as the MAX1488 and MAX3185, which are still in use today) required dual power supplies. WebJul 3, 2024 · Unlike many bus-like configurations, which use signal name, the serial communication traditionally uses function name for pins. So, if the device transmits on some pin, it is marked Tx. If it receives, it is marked Rx. Obviously you connect Tx of one device with RX of the other and vice versa.
