Abstract
The invention relates to a data transmission device for transmitting data between an Ethernet connection (3) suitable for energy transmission and a lighting mains current-free two-wire connection (4). According to the invention, a means for energy transmission is disposed between the Ethernet connection (3) and the lighting mains current-free two-wire connection (4).
Claims10
A data transmission device for transmission of data between an Ethernet connection, which is suitable for power transmission, and a two-wire connection which carries no mains current, characterized in that a means is provided for power transmission between the Ethernet connection and the two-wire connection which carries no mains current.
The data transmission device as claimed in the preceding claim, characterized in that the means for power transmission is designed to transmit power from the two-wire line to the Ethernet connection.
The data transmission device as claimed in one of the preceding claims, characterized in that the means for power transmission is designed to transmit power from the Ethernet connection to the two-wire line.
The data transmission device as claimed in the two preceding claims, characterized in that the means for automatic power transmission is designed to selectively transmit power from the two-wire line to the Ethernet connection, or vice versa, in particular as DC voltage power.
The data transmission device as claimed in one of the preceding claims, characterized in that a power consumption detection means is provided, in order to detect whether a power load is connected to a connection and, in response to this, to transfer power to a connection such as this, simultaneously with data transmission.
The data transmission device as claimed in one of the preceding claims, characterized in that the data transmission device itself is supplied with power via the Ethernet connection and/or the two-wire connection which carries no mains current.
The data transmission device as claimed in one of the preceding claims, characterized in that the two-wire connection which carries no mains current is designed for connection to a low-voltage two-wire line, in particular for connection to a bell wire and/or telephone wire line.
The data transmission device as claimed in one of the preceding claims, characterized in that the data transmission device is designed for transmission of data via the Ethernet connection at a higher data rate than via the two-wire line, with a plurality of Ethernet connections being provided.
The data transmission device as claimed in one of the preceding claims, characterized in that more than one Ethernet connection is provided, and data can be transmitted between the Ethernet connections at a data transmission rate which is higher than the data transmission rate via the two-wire line which carries no mains current, with the data transmission device being provided, in particular, with a switch, route and/or hub capability.
The data transmission device as claimed in one of the preceding claims, characterized in that the device is intended to additionally and/or separately supply power to a load which is connected without data being transmitted.
