OLA can act as a gateway, where it converts between different protocols. It can also be used by client applications to communicate with DMX devices.

OLA supports the following:

Other features include:

Supported Platforms

OLA runs on Linux, Mac OS X and FreeBSD. It's been tested to run on x86, x86_64 & arm platforms.
