![]() ![]() Serial printer cables are used to connect computers and printers with serial port features. V.35 crossover cables, which enable enhanced data rates and increased transfer speeds. Null modem cables, which ensure connection stability between two PCs where no modem is present. With the help of adapters, it is still possible for devices to communicate with each other using old and new standards.Industry examples include industrial automation systems, scientific instruments, point of sale technologies, consumer products and industrial circuit boards.What are the different types of assemblies?Basic DTE-DCE cables with universal compatibility features, typically used in data terminal equipment and data communication applications. The cable assemblies are used for connecting computers to printers, PLCs to HMIs, input, and output modules and even motor drives. D-SUB 9-pin connector cable hun/hun serial 1: Serial cable, 9-pin (socket. Even if you wish to buy a USB to serial cable, we got you covered.What are serial cables used for?Although serial cables have been replaced in some areas by Ethernet, wireless and USB connectors technologies, they are still used in some applications. D-Sub 9-pin null modem connector cable (socket - s. Whether you need a RS 232 cable, BD9 connector, or DB9 cable, you can easily purchase what you want from our store. Russell McMahon mentions several different 'standards' for wiring RS-232 to the 4 pins of a RJ11 connector or the 8 pins of a RJ45 connector. Cable ends often incorporate strain relief for added flexibility.Take a look at our store to get your serial cables. The connectors can be plugs (male) or sockets (female). D-subminiature connectors could be DB9 (9-pin) or DB25 (25-pin). RS offer a selection of high-quality serial cables from leading brands including Phoenix Contact, Startech, Molex, TE Connectivity and of course RS PRO.How is a RS 232 Cable made?RS232 cables are typically made from shielded cable and will be terminated with D-subminiature connectors. ![]() Serial cable assemblies mostly use the RS-232 (Recommended Standard 232) interface specifications. The cables achieve this via serial communication protocols (data sent one bit at a time). Is it possible that using an incorrect connector in such a situation would damage the customer's equipment? My best guess is that the inputs would be isolated (optically for example), but I figured I would ask the panel of experts for real-world situations and experience.Serial Cables A serial cable is a computer cable used for data transfer and information between computers. Common connectors in personal computers use either a 9 pins RS-232 connector or a 25 pins RS-232 connector. Some manufacturers use cables that physically look the same (DB9 on one end, DB25 on the other) where the pins will not match up with the RS-232 pinout. These connectors are known as the DB-9 Connector as a serial port and they are of two type Male connector (DTE) & Female connector (DCE). Even the most tempestuous software that insists on using all of the RS232 pinout can, surprisingly be short circuited. There are oodles of different types of RS232 cables, but the only real difference is which pins of the RS232 port they actually use. These connectors are often used in applications involving monitoring, control, and communication. Circuit Board D-Sub Connectors Add a D-sub connection to a printed circuit board (PCB). My question is - are there any situations where it is dangerous to cross signals, or could potentially cause damage to equipment by using the wrong cable?įor example, I was in the field looking to connect to a DB25 connector via a DB9 to DB25 RS-232 convertor cable. Then the RS232 wiring was condensed into the 9 pin connector, a victim of evolution if you like. How can we improve 245 Products Electrical Wiring and Connecting D-Sub Connectors Assemble DB and HD connectors to replace worn out connectors. The Apple Macintosh computer uses a circular 9-pin DIN connector, and there are several popular (and incompatible) systems for using standard modular telephone cords. I understand most or all of the signals involved with RS-232 (TX, RX, RTS, CTS, DSR, DTS, DCD, and RI on older systems, etc.) I know that many applications call for a null modem to cross TX and RX signals between certain device connections (like DTE to DTE connections for example.) A number of nonstandard RS-232 connectors are also in use. Even if you wish to buy a USB to serial cable, we got you. Whether you need a RS 232 cable, BD9 connector, or DB9 cable, you can easily purchase what you want from our store. Cable ends often incorporate strain relief. I have been working a lot with RS-232 lately and had a fundamental type of question. D-subminiature connectors could be DB9 (9-pin) or DB25 (25-pin). ![]()
