Claim Text:
1. A connection device for connecting first electronic equipment to second electronic equipment, the device comprising first and second Ethernet type interfaces that are linked together by an up line and a down line and that are arranged for each of them to be linked to a respective one of the first and second electronic equipment and to transmit data in differential mode, first and second power supply modules, each associated with a respective one of the first and second electronic equipment and wired in common mode between the up and down lines in order to transmit a power supply carrier signal in alternating current, and first and second secondary transmission modules, each associated with a respective one of the first and second power supply modules and arranged to enable data to be transmitted by modulating the power supply carrier signal in accordance with a data stream, wherein the second Ethernet type interface is linked to the up and down lines via a first transformer, the second power supply module receives power from a primary of the first transformer via a second transformer, and the second secondary transmission module receives power from a primary of the second transformer and is separately connected to the second power supply module to control the second power supply module for transmitting the power supply carrier signal.
