Latest Interest In Serial Cable

Printers is not going to function devoid of printer cables, which connect printers to devices like computers, digital cameras, and scanners. They are produced with insulated wires with distinct connectors at each ends.

Before, a printer cable was typically sold at "standard" forms for PC or Mac.

If you might be reading this article, you know that there is nonetheless a need to have for serial ports in this world. Be it that a device doesn't have USB or needs one thing USB can't provide, or that the project basically does not warrant the added expense and complexity of USB, serial remains a viable answer for many projects and systems. Add to that the fact that serial will allow for longer cables and that RS232/RS422/RS485 are extremely flexible information communication protocols thanks to the flexibility of the standards themselves and also to the ease with which you may communicate in between protocols via converters, and it is no surprise that serial ports are here to stay.

A parallel printer cable consists of two parallel connectors that serve to connect parallel-enabled printers to computers. This is ordinarily put to use to connect computers to old, dot matrix printers.

That said, there are actually several places in serial communication where a bit a lot more standardization wouldn't have hurt. How many occasions have you tackled a seemingly straightforward serial communication project just to come across that you just did not have the suitable cable and connector? That can take place with USB, too, with its Mini-USB, USB-B, Mini-A along with other connector variants, but it's truly worst with serial connections where you usually have no thought hat to expect. So let's take a look at the numerous connectors utilized in RS-232/RS-422/RS-485.

Each comes in a male and female variety, and every has two rows of pins, 5 and four for the DB-9, and 13 and 12 for the DB-25. Older equipment with serial ports commonly has the substantial DB-25 connectors but those have mostly given approach to the smaller DB-9. That's because the drastically narrower DB-9 saves valuable actual estate, and also simply because only quite couple of serial connections basically use extra than nine leads.

RJ-11, of course, is what's generally identified as a modem jack, and RJ-45 is normally connected with Ethernet connections. However, RJ-11 has six wires and RJ-45 8, and that is typically adequate even for complex serial connection projects.

USB printer cable

One neat factor about all those unique serial connectors is that it's really simple to convert from one to the other. Adapters and converters are readily obtainable and in the event you keep a number of the widespread ones inside your toolbox, there will not be any unpleasant surprises when you tackle a project in the field. Oh, and also make sure to carry along some gender changers. While DTEs (Data Terminal Equipment) will need to use male connectors and DCEs (Data Communication Equipment) female connectors, that's not usually the case, and then it is so substantially much easier to just pop in a gender changer than to create or purchase a brand new cable.

The USB printer cable is made up of two USB connectors and has a data transfer rate of 480 mbps. This is perfect for high-volume printing. There are some computers that have both parallel and USB ports. You can select either one depending in your printer.

Does anyone know any thing about HASP keys?

I have a toshiba satellite laptop with no parallel port. I recently purchased a program that requires a hap key to be plugged into a 25 pin female parallel port. So I bought a USB to DB25F adapter cable thinking that this would work. The program is a dos based program, and apparantly able to run on windows 98, NT, but I am not sure about XP. Anyways, when I try to install the program, it doesnt recognize the hasp key as being plugged into the laptop. Does DOS not recognize USB ports when XP emulates DOS?

No, DOS does not recognise USB (WinNT either)

Using DOS emulation under XP I take it you are talking about the CMD prompt? If so, I believe the pinout between the USB and the DB25 is not sending the signals on the right pins which is causing your problem. You might want to talk to the vendor of the software for a sutable hardware solution.
