A DB-9 connector is a 9-pin connector, approximately 2cm long by 0.75cm wide, with two rows of pins or sockets, a row of 5 and, a row of 4, hence 9 pins total. It is often used in low-speed data communications such as RS-232, and is the connector on personal computers since the IBM PC-AT used for COM ports. There are larger versions with 15 pins, called DB-15 and used for game ports and 10Base5 network AUIs, and 25 pins, called DB-25 and used for earlier COM ports and printer ports among other things.

The application of USB?

USB stands for "Universal Serial Bus". It was designed to be a common, easy way to connect a very wide variety of devices to a computer. USB has replaced the PS/2 keyboard and mouse ports, printer ports, DB9 serial ports, external SCSI, and many, many other device buses. USB can be used for just about anything.If you are talking about a software application required for USB, there is none. Device drivers are required for USB operation, but those are usually generic and can be found on your manufacturer's webpage.If this does not answer your question, please clarify in the discussion page.


Which type of port is used for low speed dot matrix printers?

Traditionally the DB25 parallel port and DB9 serial ports are associated with low speed matrix printers. Special printers are used for printing matrixlike prints such as cash register receipts, which typically are printed using a thermal technology which is almost infinitely quiet compared to a matrix printer. With a dot matrix printer using a typerwriter approach the noise you hear is mostly the actual printing, but with thermal and other technologies like Jet Ink the same type of print can be made using less noise. With newer technologies the connection ports often do not differ much, but there is a tendency in the direction using USB ports instead. Perhaps one day a printing device can only be connected to one type of port, call it PortX, of which there are many on the computers. When the same port type can beused for most things you can add anything in sufficient numbers to a computer if you need it. Back in the old days you could only have one keyboard (PS/2) and one mouse (DB9), one printer (DB25) and one graphics display (DB15). Today you can have all of those on USB and if you need more just add one as long as you have available USB ports.


Definition of console cable?

A serial cable used to attach to a piece of computer equipment that does not have normal input and outputs e.g. keyboard and monitor. You use another computer to attach to the first via the serial port and cable and use a communications program to use the first computer's operating system. Medium to upper level Cisco and HP routers all have a console port for serial access.

What is the difference between a serial port and a parallel port?

Parallel ports are easy to program and faster compared to the serial ports. But main disadvantage is it needs more number of transmission lines. Because of this reason parallel ports are not used in long distance communications. Let us know the basic difference between working of parallel port and serial port. In serial ports, there will be two data lines: One transmission and one receive line. To send a data in serial port, it has to be sent one bit after another with some extra bits like start bit, stop bit and parity bit to detect errors. But in parallel port, all the 8 bits of a byte will be sent to the port at a time and a indication will be sent in another line. There will be some data lines, some control and some handshaking lines in parallel port. If three bytes of data 01000101 10011100 10110011 is to be sent to the port, parallel port communication is faster then serial port.

How do you connect innova 3130 scanner to PC?

Plug the included serial connection (RS-232, DB9) into the male DB9 port on the back of a computer. You need to install the software that come with the scanner too. Once I plugged mine in, it connected right away no problems and was able to read codes from the scanner from the computer. If you don't have a serial port, you can get a RS-232 to USB adapter to use with a USB port. J. Frontbutt
