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.
