FireWire 400 Connector IEEE1394a

FireWire 400 Connector:
The 6-pin FireWire 400 technology supports serial I/O at 100, 200, and 400 Mbps and provides up to 7 watts of power when the computer system is on or when the power adapter is connected and in sleep mode.

The FireWire 400 connector has six contacts, as shown in Figure 3-2. The connector pin assignments are shown in Table 3-2.

Figure 3-2 6-pin FireWire connector:

Table 3-2 Pin assignments on the 6-pin FireWire connector
Pin	Signal name	Description
1	Power	Unregulated DC - 12.8 VDC nominal
2	Ground	Ground return for power and inner cable shield
3	TPB-	Twisted-pair B, differential signals
4	TPB+	Twisted-pair B, differential signals
5	TPA-	Twisted-pair A, differential signals
6	TPA+	Twisted-pair A, differential signals
Shell	—	Outer cable shield

When the computer is on or the power adapter is connected, the power pin provides a maximum voltage of 12.8 V (no load) and 7 W power per port. Maximum output current for both ports combined is 1.5 A and is controlled by a self-resetting fuse.

Pin 2 of the 6-pin FireWire connector is ground for both power and the inner cable shield. If a 4-pin connector is used on the other end of the FireWire cable, its shell should be connected to the wire from pin 2.

The signal pairs are crossed in the cable itself so that pins 5 and 6 at one end of the cable connect with pins 3 and 4 at the other end. When transmitting, pins 3 and 4 carry data and pins 5 and 6 carry clock; when receiving, the reverse is true.

More Information on FireWire 400:
In spite of a maximum rate of 400 Mbps for FireWire (S400) and up to 480 Mbps for USB 2.0, USB is trailing behind. Why? The performance disparity hinges on FireWire&squot;s application, which offers more robust data transfer overall compared to USB. more...

More Information on FireWire 800:
The FireWire advantage can be summed up in three words: speed, speed and more speed - at 800Mbps, it has more than two times the usable bandwidth of USB 2.0, which makes it the perfect choice for high-speed storage and serious video capture. more...
