[ IEEE 1394 CONTROLLER // EXPANSION CARDS ]
SYBA SD-PEX30001
PCI Express FireWire 400 adapter with two 6-pin and one 4-pin IEEE 1394a port. Verify the exact board label and revision before service.
MODEL SCOPE: SYBA SD-PEX30001. Specification distinctions below identify 1394a/1394b rates, physical bus and power limitations; host OS and driver support can change by revision and release.
Specifications and compatibility
| Exact model / SKU | SYBA SD-PEX30001 |
|---|---|
| Controller chipset | VIA VT6315 IEEE 1394 controller, as identified for this model family by SYBA product documentation. |
| PCI bus / lanes | PCI Express x1. |
| IEEE 1394a rate | IEEE 1394a / FireWire 400, up to 400 Mb/s per link. |
| IEEE 1394b rate | Not a 1394b / FireWire 800 adapter. |
| Ports and connectors | Two external 6-pin IEEE 1394a connectors and one external 4-pin IEEE 1394a connector. |
| Power / bus-power notes | 6-pin connectors can provide FireWire bus power when supported by card circuitry/host supply; the 4-pin connector is data-only. Verify the card’s power arrangement and do not assume the 6-pin ports are independently current-limited. |
| OS driver compatibility | SYBA supplies model-specific downloads; otherwise use the operating system’s IEEE 1394 OHCI driver. Confirm the driver package supports the exact Windows/macOS/Linux release before installation. |
| Host compatibility | PCIe x1 host interface; verify slot clearance, operating-system OHCI support and that the connected peripheral’s power requirements are met. |
Installation and archival notes
- Match the card’s printed model/revision and connector layout to the cited maker documentation; do not infer a controller IC or current limit from the connector alone.
- IEEE 1394 link rate is negotiated with the peripheral and cable. A FireWire 800 connector does not make a 400-Mb/s device or cable operate at 800 Mb/s.
- Use ESD precautions; validate system bus wiring, driver version, peripheral power source, and application-level compatibility before replacing a working legacy host.
