Ajout d'une capacité de câblage supplémentaire à un poteau central de 1,5 pouce pour des flux vidéo et accessoires supplémentaires
Il y a 21 ans. Le matériel et les prix ont peut-être changé depuis.
Ce que le fil a révélé
- Le connecteur Lemo à 8 broches standard sur des poteaux de 1,5 pouce limite la capacité du fil, avec une diminution de 13 ampères à 8 broches à 9 ampères à 12 broches à mesure que le nombre de broches augmente.
- La mise à niveau vers un connecteur Lemo plus grand nécessite des modifications importantes à la fois à la poste et junction boxes, plus un nouvel usinage, ce qui le rend coûteux et potentiellement coûtant plusieurs centaines de dollars par connecteur.
- Alternative approaches include using a 10-pin Lemo connector with thicker gauge cable, which may fit in existing posts if only the connectors are swapped out.
- Some manufacturers offer 2-inch posts with smaller connectors or multi-pin systems that can carry multiple video feeds, tally signals, and camera data simultaneously through a single post.
- Auxiliary power ports designed for specific base plates can be repurposed to free up additional conductor lines in existing connector systems.
- Direct soldering of cables without connectors allows maximum wire capacity limited only by post inner diameter and collapse specifications, though this sacrifices serviceability and repairability.
Dépend de
- Amperage ratings decrease as connector pin counts increase, potentially creating power delivery constraints.
- Heavily modified posts become difficult to repair in the field and may require spare units to be built.
- Switching to larger connector systems forces complete rewiring of upper and lower junction boxes.
- Some solutions mentioned were based on product specifications from 2000-era catalogs and may not reflect current offerings.
- The discussion does not conclusively determine which off-the-shelf solution best meets multi-video requirements.
