COSINE NANOELECTRONICS LAUNCHED THE RS485 CHIP COS13487EESA WITH AUTOMATIC TRANSCEIVER CONTROL FUNCTION

RS-485 is a half-duplex communication interface that uses differential signals for transmission, also known as TIA-485-A, ANSI/TIA/EIA-485 or TIA/EIA-485. Because it is half-duplex, in the usual use of 485 communication, it is necessary to switch the sending or receiving function. The conventional method is to use the RE pin and DE pin (see Figure
