Erweitern von Infrarot-Fernbedienungssignalen zu einem Recorder mit Glasfaserkabel
20 Jahre alt. Geräte und Preise können sich seitdem geändert haben.
Was die Diskussion ergab
- Optische Audiokabel, die für Heimkinosysteme entwickelt wurden, können wiederverwendet werden, um Infrarotsignale von einer Fernbedienung zu einem Recorder zu übertragen, indem die sperrigen Anschlussenden sorgfältig entfernt und in der Nähe des Senders und Empfängers positioniert werden.
- Passive Glasfaserlösungen funktionieren besser mit Infrarot-LEDs mit höherer Leistung; schwache Sender mit Münzzellenbatterien können Schwierigkeiten haben, mit ausreichender Intensität durch das Kabel zu übertragen.
- Photosensors used in receiver designs must be rated for the infrared spectrum range rather than visible light, as standard photocells peaked in the visible spectrum show poor sensitivity to infrared wavelengths.
- The receiver circuit must pass the 36-44 kilohertz data carrier frequency used by infrared remote systems without distortion for proper operation.
- Modifying a remote control by replacing its infrared LED with one having a wider viewing angle reduces transmission distance due to the same power output being spread over a larger area.
- Active infrared extenders exist but require external power supplies and additional components, making them less suitable for portable sled-mounted applications.
Hängt ab von
- The feasibility of fiber optic signal transmission depends heavily on the specific power output characteristics of the infrared LED in the remote being used.
- Optical cable solutions have not been confirmed as successfully implemented in the thread; suggestions are based on theoretical possibility rather than tested results.
- Home theater infrared repeater systems designed for stationary installations may not be practical for mobile sled use due to power and component requirements.
- The specific recorder model and its infrared receiver specifications are not mentioned, affecting compatibility assessment.
