8/11/2023 0 Comments Db9 connector pinout![]() Use a multimeter to test whether the two ends are connected directly with a multimeter to determine whether the two ends are connected, just test 2/3/5 pins. DB9 connectors are usually used for CAN: DB9 female connectors are located on the bus, while DB9 male connectors are located on the device.ġ. However, this use is not standardized between DB connector manufacturers and may require special cables.ĭE9 connectors are used for some token ring networks as well as other computer networks. These typically do not send data serially to the computer, but instead use a handshake control line to indicate low battery, power failure, or other conditions. Many uninterruptible power supply units are equipped with DB9 connectors to send signals to a connected computer through the RS-232 interface. RS-232 devices originally used DB25, but for many applications, the less common signals were omitted, allowing the use of DB9 female and male connectors. The most widespread use of D-subs connectors is for RS-232 serial communications, although the standard does not mandate such connectors. ![]() So now it is common to sell DE9 connectors as DB9 connectors, and DB9 means 9-pin connector with E size shell. However, due to ignorance, it was usually labeled as DB9 instead of DE9 connector, incorrectly using B to indicate the fact of shell size. For example, computer first used DB25 connector as its serial and parallel port when PC serial port started to use DE9 D-sub 9-pin connector. In addition, DB9 connector is DE9 D-sub 9-pin connector, just incorrectly called "DB9" connector, where E is the size of the shell. DB9 is the smallest model of D-Subminiature connector, DB9 female connector has 9 pin holes, while DB9 male connector is 9 pins. In fact, DB9 connector is a common electrical connector, is one of the common D-Sub type of connectors. Many people do not understand what is DB9 connector. What is DB9 connector and what are the applications of DB9 female and male connectors? IV Is serial cable directly connected or crossed? III How to test the quality of the serial port cable? ![]() This article will focus on the definition and test method of DB9 connector port and introduce DB9 port in detail.Ģ.3 Computer video output, game controller port DB9 connector s are commonly used in serial communication. ![]()
