Service & preservation
Preserve the permanently attached cables and label host/MIDI directions. Inspect leads for strain and test data flow in both directions independently. Save the system driver mode and OS version; avoid bending the cable at the molded USB end.
Identification and compatibility checks
- Photograph the product/model label, board silkscreen/revision, connector faces, cable assemblies, and accessory part numbers before installation.
- Check electrical bus and host slot or USB/MIDI protocol support against the exact manual; connector shape alone does not establish compatibility.
- For analog I/O, confirm line/mic/instrument level, phantom-power behavior, channel map, and direction from the model-specific documentation before connecting equipment.
- When software or driver support is uncertain, preserve the last known-good installer and document tested host OS, driver version, and device identifier.
