What the status labels mean

Confirmed: Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source: Only one underlying document, or one pass, supports this assignment.
Device-specific: Supported for the named equipment or wiring only. Check your device’s manual.
Unverified: Missing or conflicting evidence. Do not wire from this row.
Not connected: The source explicitly says NC, no contact or no pin for this wiring.

P258 LEMO 3K.93C (SMPTE 304M) — **Partial, consistent** — A has only contact classes from LEMO's catalogue: 2 single-mode fibre, 2 power, 2 signal, shell earth. B read SMPTE ST 304 and 311 (free on SMPTE's server), which give colour-coded contacts (blue and yellow fibre, red and grey low-voltage, black and white auxiliary) for the plug and jack ends but no contact numbers. The two are consistent but at different levels of detail, and neither establishes per-contact function or polarity. **Publish as contact classes and colours only.**
pin_number values are contact-class labels written for this pass, not LEMO or SMPTE contact designations.
SMPTE ST 304 and ST 311 are paywalled and were not consulted. Per-contact designations, which power contact is the 'N' contact, the use of the two signal contacts, and fibre direction (camera-to-CCU vs CCU-to-camera) are not established.
The insulator drawings show six contacts of three visual types plus the 'N' marking but no legend; mapping drawn shapes to fibre/power/signal was not done to avoid guessing.
Not consulted; any differences from SMPTE wiring are unknown.
