Das
Relais
Das
Relais
Die Ethernet-Vorrichtung weist einen ersten Zustand und einen zweiten Zustand auf. Der erste Zustand entspricht einer Bedingung, bei der die Ethernet-Vorrichtung schon Strom für den Betrieb verlangt hat. Der zweite Zustand entspricht einer anderen Bedingung, bei der die Ethernet-Vorrichtung nicht Strom für den Betrieb verlangt hat. Zum Beispiel ist der erste Zustand ein POE-aktiviert-Zustand, und der zweite Status ist ein POE-deaktiviert-Zustand.The Ethernet device has a first state and a second one State on. The first state corresponds to a condition in which the Ethernet device has already requested power for operation. The second state corresponds to another condition in which the Ethernet device has not requested power for operation. For example, the first state is a POE-enabled state, and the second status is a POU disabled state.
In
dem zweiten Zustand ist, da die Ethernet-Vorrichtung nicht Strom
für den
Betrieb verlangt hat, der Spannungserzeuger
Wenn
die Ethernet-Vorrichtung mit dem benötigten Betriebsstrom versorgt
ist, ist sie in dem ersten Zustand, und der Spannungserzeuger
In
einem anderen Ausführungsbeispiel
empfängt,
wenn das erste Empfangsende VIP das erste Signal empfängt, das
zweite Empfangsende VIN auch ein zweites Signal, welches ein negativer
Verbindungsimpuls des zuvor erwähnten
Differenz-Verbindungsimpulses
ist. Das zweite Signal ist über
den dritten Kondensator C3 mit dem Steuerungsende des zweiten Transistors
T2 AC-gekoppelt. Indes ist das zweite Signal ein negativer Impuls
und könnte
den zweiten Transistor T2 ausschalten. Die zweite AC-Kopplungseinheit
