Abstract
In one or more embodiments, a T-adapter includes an input for receiving power and data on a wire pair, a first output for transmitting the power and data to a first load, a second output for transmitting the power and data to a second load, and a controller operable to detect and authenticate the first load at the first output or the second load at the second output and enable power at the first output or the second output in response to load detection and authentication.
Claims20
A T-adapter comprising:
- an input for receiving power and data on a wire pair;
- a first output for transmitting the power and data to a first load;
- a second output for transmitting the power and data to a second load;
- and
- a controller operable to detect and authenticate said first load at said first output or said second load at said second output and enable power at said first output or said second output in response to load detection and authentication.
2 more elements
A method comprising:
- receiving power and data at an input of a T-adapter;
- detecting a first load at a first output at the T-adapter;
- transmitting the power and data at said first output;
- detecting a second load at a second output at the T-adapter;
- and
- transmitting the power and data at said second output;
- wherein at least one of said first load or said second load is authenticated at the T-adapter before transmitting power at said first output or said second output.
4 more elements
A system comprising:
- a plurality of powered devices;
- and
- a plurality of T-adapters each comprising an input for receiving power and data, a first output for transmitting the power and data to one of the powered devices, and a second output for transmitting the power and data to the input of a downstream T-adapter or another one of the powered devices;
- wherein each of the T-adapters comprises a controller for detecting the powered device at said first output and transmitting the power and data to the powered device, and detecting the downstream T-adapter or the powered device at said second output and transmitting the power and data to the downstream T-adapter or the powered device.
