IEEE 1394 connectors
Similarly, many modern-day motherboards provide a pin header that allows connection to a front-mounted IEEE-1394 port.
With this system case, there are six wires coming from its front-mounted IEEE-1394 port. These consist of two sets of twisted pair cables (TPA and TPB), a power cable (VP) and a ground cable (VG).
The Intel Front Panel Connectivity Guide recommends the following design for a front-mounted IEEE-1394 connectors. If your motherboard is a recent design, it's likely it will be identical, or at least similar.
| Pin | Signal name | Pin | Signal name |
|---|---|---|---|
| 1 | TPA+ | 2 | TPA- |
| 3 | Ground | 4 | Ground |
| 5 | TPB+ | 6 | TPB- |
| 7 | +12V (Fused) | 8 | +12V (Fused) |
| 9 | Key | 10 | Ground |
