Digital addressable lighting interface bridge
First Claim
1. An apparatus for bridging a digital interface to a digital addressable lighting interface (DALI) interface, comprising:
- a digital interface;
a digital addressable lighting interface (DALI) interface adapted for connection to a DALI bus; and
a processor coupled between said DALI interface and said digital interface, wherein said digital interface is adapted to receive address and control information, said processor formats the received address and control information into a DALI standard format, and said DALI interface is adapted to transmit the DALI standard formatted address and control information onto the DALI bus.

Abstract
An interface bridge between a standard input-output (I/O) computer port and a Digital Addressable Lighting Interface (DALI) interface. The DALI bridge translates signal levels and protocol from the standard I/O computer interface port to the DALI signal levels and protocol, and visa-versa. A digital processor is used for protocol translation and message buffering. Signal level translation is used to properly connect to a the computer port and the voltage levels of the two wire DALI bus. Using a standard computer for testing and control of a DALI compliant device and/or plurality of DALI compliant devices in a building lighting system is facilitated by the DALI bridge.
