steps
what you'll need: UpdaterAtor (recommended) or push from fixture via wired DMX chain
1Option A - UpdaterAtor: Connect via ETC Gateway/Gadget. Launch UpdaterAtor. Select CS V fixture(s) and update.
2Option B - Push from fixture: Remove power and DMX In from source fixture. Hold Up and Down simultaneously while restoring power. Display shows 'Udt rdy'. Press Mode. Display shows progress on pushing fixture ('Udt' + percentage) and on receiving fixtures ('dL rdy' then 'U:XX'). Display returns to previous value when complete. Reconnect DMX In.
Warningv4.3.1 applies ONLY to ColorSource Spot V. Do not attempt to install on other CS V fixtures.
Gotchav4.3.0 is the current release for ColorSource PAR V Zoom and ColorSource Fresnel V (including V Fresnel MAX).
GotchaCAUTION: If reverting from v4.3.0 or later to an earlier version, restore fixture defaults first to avoid unexpected behavior from configuration differences.
GotchaUpdaterAtor update can sometimes freeze; workaround is to power-cycle the fixture which restarts the update.
WarningMixed DMX runs: other fixture types do not need to be disconnected before pushing.
GotchaConfiguration changes just before power loss may not be saved.
