Description
AN-EXT-RS-232 extends full-duplex transmission of asynchronous data over four wires (two twisted pairs). The data transmission between each line driver utilizes differential signaling that is immune to electrical interference and therefore makes it ideal for use in light manufacturing and industrial office areas. It can run up to speeds of 57.6 kbps
