Extended signaling capacity in a DALI system

Abstract

The invention relates to a signaling device (2) for use in a DALI system (1) with a DALI bus (B), wherein, according to the DALI standard, an upper voltage value range (DH) is established for the bus voltage of the DALI bus (B) for transmitting a high-level DALI signal via the DALI bus, and the bus voltage of the DALI bus (B) lies within the upper voltage value range (DH) in the idle state, wherein the signaling device (2) is configured for being connected to the DALI bus (B) of the DALI system (1), and wherein, in the connected state, the signaling device (2) is configured to change the bus voltage of the DALI bus to a predetermined voltage value (U2) within the upper voltage value range (DH) in the idle state. The invention also relates to a DALI device (3a, 3b, 3c) for use in a DALI system (1) with a DALI bus (B), which is configured for registering the above-mentioned signaling using the signaling device (2) according to the invention.
