Connessioni per dischi fissi esterni

Interfacce di connessione

Parallel and Serial connectors

The parallel and serial ports are built onto the back of the motherboard. You would most likely connect a parallel printer to this port. Otherwise you may even connect a parallel or serial data cable.

Power Connector (AT or ATX)

The industry standard ATX power-supply–to–motherboard main connector is the Molex 39-29-9202 (or equivalent) 20-pin ATX style connector.

As motherboards and processors evolved, the need for power became greater. In particular, chipsets and DIMMs were designed to run on 3.3v, increasing the current demand at that voltage. In addition, most boards included CPU voltage regulators designed to convert +5v power into the unique voltage levels required by the processors the board supported. Eventually, the high current demands on the +3.3v and +5v outputs were proving too much for the number and gauge of the wires used. Melted connectors were becoming more and more common as these wires overheated under these loads.
Finally, Intel modified the ATX specification to add a second power connector for ATX motherboards and supplies. The criteria was that if the motherboard needed more than 18A of +3.3v power, or more than 24A of +5v power, an auxiliary connector would be defined to carry the additional load. These higher levels of power are normally necessary in systems using 250-watt to 300-watt or greater supplies.

To augment the supply of +12v power to the motherboard, Intel created a new ATX12V power supply specification. This adds a third power connector, called the ATX12V connector, specifically to supply additional +12v power to the board.

USB Universal Serial Bus

USB version 2.0 is a "peripheral connection interface" for external devices. USB is supposed to be what you'll connect digital camera, joysticks, keyboards, modems, scanners, mice, and anything else that use USB ver. 2.0 interface. USB 2.0 is also backward compatible to USB version 1.1 type peripherals.


Schema elettrico dell’attacco USB
(Universal Serial Bus)
L'USB (Universal Serial Bus) è uno standard per interfaccia seriale per la telefonia e i dispositivi multimediali.
Ciascuna porta USB è un connettore singolo per il collegamento di dispositivi che in precedenza utilizzavano porte seriali, parallele, per la tastiera, per il mouse e per i giochi. La tecnologia USB utilizza la tecnologia Plug and Play per determinare quale dispositivo è collegato al connettore. E' possibile accedere a ciascun dispositivo USB tramite un indirizzo USB univoco. Per convertire una porta USB in più punti di collegamento viene utilizzato un dispositivo chiamato "HUB". Un HUB dispone di più porte alle quali è possibile collegare delle periferiche.
L'USB fornisce una larghezza di banda di 12 Mbps (megabits-per-second) con un massimo di 63 periferiche e una istanza massima del segnale di cinque metri per segmento..
La tabella seguente illustra le assegnazioni dei numeri dei piedini per il connettore USB.

Velocità di trasferimento dati
100, 200, 400 e 800 Megabit al secondo (Mb/s)
Alimentazione
Voltaggio di ingresso: 8-33 volt (V)
Potenza di ingresso: circa 1 watt (W)
Voltaggio di uscita: circa 18-24 V
Potenza di uscita: fino a circa 15 W
Sicurezza
Il bus FireWire ha 3 fusibili a reset automatico. Spegnimento inaspettato della periferica: Se la periferica FireWire si spegne, questo problema può essere dovuto a un fusibile in sovraccarico. In questo caso, scollegare immediatamente il dispositivo.
Funzionalità ripetitore
La funzionalità ripetitore incorporata consente il trasferimento dei dati FireWire tra il computer e le periferiche esterne anche a computer spento. Nelle periferiche auto-alimentate, il ripetitore viene alimentato tramite il cavo FireWire. La funzionalità ripetitore non è supportata dalle periferiche non auto-alimentate.
La funzionalità ripetitore richiede tra 8 e 33 V e consuma circa 1 W.
Cavi FireWire
I cavi FireWire sono disponibili presso molti rivenditori di materiale elettrico; a seconda del produttore, possono essere chiamati cavi IEEE 1394 oppure avere un altro marchio specifico.
I cavi sono disponibili in varie lunghezze; le lunghezze standard sono 0,7 m, 2 m e 4,5 m. I cavi sono provvisti di connettori a 4 pin o 6 pin.
Connettore a 4 pin 1394 e connettore a 6 pin 1394 (FireWire)
Porta e connettore a 6 pin 1394 (FireWire)
Nota: I cavi con connettori a 6 pin trasmettono l'alimentazione e i dati da un dispositivo all'altro, mentre i cavi a 4 pin trasmettono solo i dati. Prima di acquistare i cavi, verificare il tipo di connettore utilizzato dal dispositivo. La porta FireWire del computer accetta solo connettori a 6 pin, sebbene siano disponibili i seguenti tipi di cavo:
cavi con connettori da 6 pin a 6 pin
cavi con connettori da 4 pin a 4 pin
cavi con connettori da 6 pin a 4 pin
AVVISO: Non tentare di forzare un connettore a 4 pin in una porta a 6 pin su una periferica. A volte, le porte a 4 pin possono essere alquanto fragili; prima di connettere un connettore a 4 pin alla relativa porta, allinearlo attentamente alla porta e non forzarne l'inserimento. Alcuni connettori si bloccano automaticamente nella porta; per scollegare un connettore auto-bloccante, esercitare una lieve pressione sui lati del connettore mentre lo si estrae.

DVI Digital Visual Interface .. standard for high-speed, high-resolution digital displays. Developed by the Digital Display Working Group (DDWG).

Digital Video Broadcasting/Digital Audio-Visual Council (DVB/DAVIC), developed by DAVIC and DVB and adopted by European Telecommunication Standards Institute (ETSI) and International Telecommunication Union (ITU)

DVI has a number of different types connectors:
DVI-D Digital only connector; 24 pins [modified D style]
DVI-I Digital and Analog [RGB]; 29 pins [modified D style]
DFP Digital only connector





DVI was developed by the Digital Display Working Group (DDWG). It carries the same type of signal as the DFP connector; however, the connector is not the same physically or in terms of pin out. The DVI connector comes in two forms, a 24-pin version and a 29-pin version. The 29-pin version allows an analog signal to also be carried. Signal type: analog and digital

DVI Tutorial

1) What is the difference between Dual Link and Single Link? Which do I need?
Dual link enables a higher resolution (1920 X 1080) and more channels. You can view 2 displays simultaniously. If in doubt, order the Dual Link cable because it is backwards compatible with Single Link.

2) I need a DVI-I to DVI-D cable - What part number do I buy?
A DVI-I enables digital and analog signals. A DVI-D only allows digital signals. The part number to buy is DVIDL-length

3) Why are your DVI cables so much less?
You are coming right to the source. Our cables meet all wiring specifications. We don't know why everybody else is so expensive.

4) Is there a distance limitation?
Yes. For digital DVI cables there is a 5 Meter distance limitation. If you go longer the video results will be unpredictable and not guaranteed. The only way to safely and efficiently go longer distances is to use our OC and OLC series DVI fiber cables.

5) What is the TFT LCD?
TFT stands for "Thin Film Transistor" and describes the control elements that actively control the individual pixels. For this reason, one speaks of so-called "active matrix TFT's". LCD means "Liquid Crystal Display" and stands for monitors that are based on liquid crystals.

6) What's the difference between CRTs size and TFT size?
The visible diagonal size of a CRT tub monitor is always smaller than the tube's actual diagonal size. For example: a 17-inch CRT monitor has an edge area and it's visible diagonal is only 16-inches. But TFT LCD monitors do not have an edge area. This means that a 15-inch TFT LCD monitor is almost the same as the 17-inch CRT monitor.

7) What's the Contrast Ratio?
The Contrast Ratio is derived from the maximum and the minimum values for brightness.

8) What's the difference netween Digital and Analog Interface? Any advantages or disadvantages?
TFT LCD monitors with an analog VGA interface dominate the market. Because it is easy to install PC basis and not purchase a new graphics board. Although digital TFT LCD monitors don't need to adjust clock and phase and the no signal losses advantage. The Digital Interface standard has totally different connectors and it is not easy to buy a suitable graphic board. So the analog TFT LCD monitors still dominate the market. The following table gived you an overview of the most important points:
Digital Control Analog Control
Advantages
  • No signal losses due to DA and AD conversion
  • Geometry, clock and phase settings unnecessary - therefore simple to use
  • Lower costs as less electronic circuitry required
Disadvantages
  • Currently three standards (P & D (M1DA), DFP, and DVI)
  • Low availability of models with digital interfaces
  • Requires graphic board with digital output
Advantages
  • Compatible with standard VGA boards on a broad installed PC basis
  • Not necessary to purchase seperate board
Disadvantages
  • Clock and phase of the TFTs must be synchronized with the analog signal to avoid pixel jitter, which is a relatively complex issue
  • Cables sensitive to external influences
  • High cost of signal conversion inside the display
  • Upgrade to digital interface not possible


9) How many Digital Interfaces are there now? Which one do I choose?
Currently there are three digital interface standards (P & D (M1DA), DFP, and DVI) in the market. The following table is the comparison and summary of the three interface standards. According to the table, DVI will be a standard in the future. DVI not only allows high resolutions, it also enables the connection of analog devices.
