OLA (Open Lighting Architecture) is a framework that allows applications to send and receive DMX512, using various hardware devices and 'DMX over IP' protocols. It enables software controllers talk to DMX hardware.

OLA allows DMX sent using various DMX over IP protocols to be converted from one format to another. This enables devices from different manufacturers to talk to each another (for example a Strand Console can send DMX to an Enttec EtherGate). When combined with a physical DMX interface such as the DMX USB Pro, OLA can send and receive data from traditional wired DMX networks.

OLA can run on Linux and on Mac OS X. A port to Windows is feasible if someone wants to add the necessary platform-dependent code for plug-ins and create an installer.

OLA can also run on a wireless access point. [1]

There is a project underway to build packages for OpenWrt. See for more details.
