NETRON EN12: distribution and configuration recovery

Proposed test, scope and alternatives

EN12 NRE001 provides twelve configurable five-pin XLR IN/OUT ports in 1U. It is distinct from EN12i/EN12-45. Map every port; twelve connectors establish neither twelve separate universes nor console capacity.

Official 2.x→3 migration notes say settings/cues are erased and 2.x backups cannot import into 3. A saved file is insufficient: preserve the map and reconstruction resources.

1. On receipt, record model, Firmware/Web, IP, protocols, ports, presets, cues and triggers. Keep a version-supported backup externally and check supplier conditions before changes.
2. Propose zone mapping and model-specific mounting. Confirm power/accessories; connector type alone does not establish outdoor protection.
3. Test individual outputs with known values, then intended cues/merges and signal loss/return. Record initial and event-approved settings.
4. Before reset/update, compare source/destination notes and reconstruction requirements. Schedule maintenance away from the show; a factory preset may change many routes.
5. Deliver identified configuration, map and rehearsed/pending recovery. Agree on return settings/version for a rental rather than restoring blindly.
