What can be plugged in a parallel port?
Other uses included optical disc drives such as CD readers and writers, Zip drives, scanners, external modems, gamepads, and joysticks. Some of the earliest portable MP3 players required a parallel port connection for transferring songs to the device. Adapters were available to run SCSI devices via parallel.
Are parallel port is most often used by a?
The parallel port is found on the back of IBM compatible computers and is a 25-pin (type DB-25) computer interface commonly used to connect printers to the computer.
What are parallel port used for?
A parallel port is an interface allowing a personal computer (PC) to transmit or receive data down multiple bundled cables to a peripheral device such as a printer. The most common parallel port is a printer port known as the Centronics port.
What is parallel port mode?
ECP is a Parallel Port mode that is available on most computers to increase the speed at which data is transmitted and is set in the computer’s BIOS settings. The instructions in the BIOS coordinate communication between the operating system and the computer hardware.
Can You Power an IC from a parallel port?
One method often used for powering small circuits is to use the power from data output pins directly to power the external IC. If you have one IC which takes less than 1 mA current, you can easily power it directly from one data output pin. You get around 4.5-5V to the IC very easily in this way just by using one data output pin.
Can a parallel port power a serial port?
Because there is no power output in parallel port, operating a circuit from parallel port seems to be first quite impossible. But there is one solution to this problem: steal some power from the parallel port signal lines. This same approach is used with PC serial port powered devices like PC mouse .
What should I use with parallel port transistor?
Use a 1K resistor between the parallel port pin and the base of the transistor. Use a silicon rectifier (1N400x type) as a snubber across the relay coil; anode to collector, cathode to V+.
What kind of device can use parallel port?
The same method is also useful in parallel port and some devices like copy protection dongles and some sound output devices use this method. New features in PC parallel port (EPP,ECP, IEEE 1284) make the port faster, more flexible and more standardized.
