Verified card compatibility
Rugged Computers for MIL1394 (SAE AS5643) Interface Cards
SAE AS5643 — deterministic IEEE-1394 as flown on programs like the F-35 — needs specialist interface hardware, and the test rigs around it need hosts that keep interrupt behavior predictable. The DapTechnology FireTrac4424bT below is verified in DuroPC systems; the part number in the legacy record (FT4424BT-RTX64-AS5643P) is the RTX64 real-time variant.
Multi-card 1394 rigs are where interrupt routing bites: shared IRQ lines between the interface card and its neighbors can stall deterministic traffic, and the fix is MSI — see the IRQ-sharing tech note linked below.
| Manufacturer | Model | Part number | Bus | Verified in |
|---|---|---|---|---|
| DapTechnology | FireTrac4424bT | FT4424BT-RTX64-AS5643P | PCIe | DuroPC systems — configuration verified at order |
DapTechnology FireTrac4424bT(FT4424BT-RTX64-AS5643P)
Four-node IEEE-1394 / SAE AS5643 "MIL1394" PCIe interface with IRIG time-stamping, used in vehicle-bus test programs. Verified in DuroPC systems, including the RTX64 real-time variant this part number denotes.
