Power over Ethernet
From SpinetiX Support Wiki
Power over Ethernet (PoE) is a standardized method of providing DC power over the unused wires in Cat5 cabling. It is commonly used for devices such as Wireless Access Points to avoid the need for a local power supply. As the HMP is almost always combined with a screen which requires a local power source, PoE usefulness with the HMP is limited, so it is not natively supported.
Using a PoE splitter
You can employ a separate PoE splitter which sits between the network cable and the player and transfers the power onto a standard DC jack which is plugged into the player.
The PoE splitter must meet these specifications:
- Voltage: 5V
