StarTech PEX2S5531P 2-Port Serial Card
PCIe x1 RS-232 serial adapter. This entry records a distinct product or well-defined family; differences among revisions and similarly named models are called out below.
MODEL IDENTIFICATION: Match the full model/part number, revision, and region to the item label and its manufacturer documentation. Where a family has multiple revisions, specifications below are not universal across the family.
Recorded specifications
| Cataloged part | StarTech PEX2S5531P 2-Port Serial Card |
|---|---|
| Era / family | PCIe x1 RS-232 serial adapter |
| Key specifications | Two DB9 RS-232 ports; PCIe x1; chipset and FIFO/baud support specified by exact SKU. |
| Interface / fit | Operating system driver and low-profile/full-height bracket included with exact package; serial voltage is not RS-422/485. |
| Variants / identification | Check full PEX SKU suffix; StarTech adapters with same port count may implement different electrical standards. |
| Archive record | Record full part number, hardware revision, serial/date code, firmware/BIOS, accessories, physical condition, and the documentation revision used for verification. |
Compatibility and handling
- Confirm the complete part number, connector signal/pinout, supported host, dimensions, power, firmware and operating-system requirements before use.
- Inspect for corrosion, cracked parts, bent pins, damaged insulation, failing bearings, leaking cells, or prior repair. Avoid powering unidentified or damaged hardware.
- For compatibility claims, cite a specific manual, CPU support list, interface standard, or tested host configuration; physical fit alone is insufficient.
- Record measurements with the test setup and instrument conditions; distinguish vendor maximums from measured or sustained results.
