| Verified protocol / model information | StarTech identifies ICUSB2321F as a 6 ft (1.8 m) USB-to-RS-232 adapter with an FTDI chipset and COM-port retention. RS-232 is electrical signaling; USB is translated by active electronics, not passively wired through. |
| Connector ends | USB TYPE-A HOST → RS-232 DB9; diagram is schematic, not a pinout map. |
Physical & electrical compatibility
This output is RS-232, not 3.3 V/5 V TTL UART. Verify operating-system driver support, target connector/pinout, DTE/DCE role, and the device’s serial settings. Do not connect the DB9 RS-232 output to a logic-level UART header.
Archival & handling notes
Record adapter model, driver/OS, assigned COM port, and known-good device. Protect USB and DB9 connectors from side-load; preserve any driver/media information with the adapter.
Record provenance, condition, label photographs, exact full part number/revision, host system, and any test method/result. Preserve packaging and source documents with the cable when available.
