Description

The table below lists every version of software for the original ColorSource family of fixtures, along with its release date, key information about the version, and a list of compatible fixture hardware.

ETC recommends using UpdaterAtor software to manage software updates. For information on UpdaterAtor and how to use it, see the UpdaterAtor Software Quick Guide and the UpdaterAtor Software Release Note, which you can download from etcconnect.com.

If you don't have access to UpdaterAtor, ColorSource fixtures running v1.3.0 and higher can push firmware to other fixtures of the same type and CPU. For more information, check the release notes of the version you intend to push.

This article separates version branches by CPU. For more information on CPU variants and how to identify your fixture, see: CPU Variants
