![]() 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. The pins and signals associated with the 9-pin connector are described below. Null modem cables, which ensure connection stability between two PCs where no modem is present. The pin assignment scheme for a 9-pin male connector on a DTE is given below. 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 RS-232 DB25 connector is capable of supporting two separate connections - each with its own optional clock when used in Synchronous mode or Bit-Synchronous mode. ![]() DB9 connector has 9 pins and DB25 connector has 25 pins with each pin having its own function. The cable assemblies are used for connecting computers to printers, PLCs to HMIs, input, and output modules and even motor drives. RS232 on DB25 (RS-232C) The use of each pin including methods for spoofing signals is described in our Signal/pin primer. The D-sub connectors (DB9, DB25) comes with male and female cable. 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. As we see that the data communication can be classified as DTE(data terminal equipment) and DCE(data connection equipment). 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 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). Then you should use a multimeter to determine which wires in the cable connect to which pins on the RS-232 connector. You will need an RS-232 interface chip (MAX3232 or similar) to invert the RS232 signals, and convert them to 3.3 volt logic levels. FREE delivery Thu, Nov 9 on 35 of items shipped by Amazon. So, for the OP's application, I'm going to say 'no' - not without modifying the PC's serial port and/or cable.Serial Cables A serial cable is a computer cable used for data transfer and information between computers. The processor will likely be damaged if you connect real RS-232 signals to those pins. D-SUB 9-pin RS232 RS485 Adapter to Terminal Connector Signal Module with Bolts Nuts and Screwdriver (1PCS Male+1PCS Female) 95. I doubt both can be powered from a standard serial port, and I doubt even more than the serial port it is connected to is 'standard'. Whilst many RF transciever's can operate at very low power using burst comms and low duty cycles, your average MAX232 equivilent uses up a fair few mA. I hate USB-serial adapters, they cause no end of trouble with host software, and latency issues, but they are necessary since the venerable serial port is being dropped from portable computers, and some desktops. If the OP is connecting his 'max232 and transceiver' to another embedded device, I doubt he would ask about using it for power. ![]() 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). It is no different from the suggestions to tap a PC's internal power supply, but with only a modification made to a cheap USB-serial port dongle. How can we improve 245 Products Electrical Wiring and Connecting D-Sub Connectors Assemble DB and HD connectors to replace worn out connectors. But where there's a serial port, there's generally a host system nearby - and therefore, likely a USB port. ![]()
