The COM serial products commonly used in IPCs generally have RS-232 and\nRS-485 interfaces. In appearance, both serial ports use a 9-pin type. It&#8217;s just\nthat they have different definitions of the two pins, which are not mentioned\nhere.<\/p>\n\n\n\n<p>The RS-232 serial\nport used by the COM serial port of the industrial computer is relatively more.\nRS-232 (ANSI\/EIA-232 standard) is the standard for serial connection on IBM-PC\nand its compatible machines.<\/p>\n\n\n\n<p>The COM port is a\ncommunication port that can be used in a wide variety of communication devices.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" loading=\"lazy\" width=\"295\" height=\"231\" src=\"https:\/\/www.pcstationcn.com\/blog\/wp-content\/uploads\/2019\/04\/2-4.jpg\" alt=\"\" class=\"wp-image-207\"\/><\/figure>\n\n\n\n<p>Pin function of\nthe 9-pin serial port:<\/p>\n\n\n\n<p>1 Carrier Detection\n(CD)<\/p>\n\n\n\n<p>2 Accepted Data\n(RXD)<\/p>\n\n\n\n<p>3 Send Data (TXD)<\/p>\n\n\n\n<p>4 Data Terminal\nReady (DTR)<\/p>\n\n\n\n<p>5 Signal Ground\n(SG)<\/p>\n\n\n\n<p>6 Data Ready (DSR)<\/p>\n\n\n\n<p>7 Request to Send\n(RTS)<\/p>\n\n\n\n<p>8 Clear Send (CTS)<\/p>\n\n\n\n<p>9 Ringing Indication\n(RI)<\/p>\n\n\n\n<p>The COM port is a\ncommunication port that can be used in a wide variety of communication devices.<\/p>\n\n\n\n<p>1.
