Output Window

The Output Window is arguably the core window that can be viewed in ZerOS. The Output Window will show patched fixtures in channel number order. The channel numbers of fixtures are displayed in white, with intensity percentages displayed below them.

Internal Touchscreen


The shortcut to view the Output Window on the internal touchscreen of consoles without a monitor, is hold Shift and press View.

External Desktop

If you have an external monitor or remote monitor connected, the Output window is shown on the top half of both the Cues and Faders desktops:

Intensity Colour Coding


The intensity percentages of your lights are displayed in various colours, which indicate the following:



When the channel is selected, the LED in the button under the fader will turn on, and an orange box will be drawn around the channel number in the Output Window.

The Output window will automatically scroll to show the last selected channel number.

Grey outlines around rows of fixture numbers in the Output Window indicate which set of fixtures are currently being controlled by the channel faders.



The “source” button displays what’s in control of each fixture. The following descriptions are used:

  • C 1/1 - Playback 1, Cue 1
  • C 22/5 - Playback 22, Cue 5
  • UDK 1/1 - UDK Page 1, UDK 1
  • P - Programmer
  • D - Default value

Pressing “Intensities” reverts back to the usual display, showing the current intensity of every fixture.

Live / Preview / Blind


“Live” displays the current intensity percentages outputting from the console.

“Preview” displays the intensities of the next cue (yellow bar) of the currently viewed playback. Using the up/down arrows to navigate the playback allows quick preview of upcoming cues.


“Blind” is both a visual indicator and a quick way to enter and leave “Blind Mode”.

Parameter Table

Parameter Table

At the bottom of the Output Window on the external desktops, a parameter table will open. This will show the percentages and details of all parameters of the currently selected fixtures, and fixtures that are currently in the programmer.

RDM Notifications

When RigSync is enabled, ZerOS will continuously look for any new RDM fixtures that may be connected. When a fixture is discovered, it will be processed, and then automatically patched.


When an RDM device is detected, a banner will be shown at the top of the Output window, whilst ZerOS processes information about the fixture.


If a discovered and patched RDM fixture stops responding, an X will be shown next to the fixture's channel number, and an error message will be displayed at the top of the Output Window. A "Dismiss" button is provided to dismiss the notification. A "View Notifications" button will display if more than one fixture stops responding.

Multicell Fixtures

"Multicell" fixtures, are fixtures that have multiple light sources which can be controlled individually. When all the "cells" of a multicell fixture are at the same intensity level, the fixture will be shown in the Output window like any normal fixture.


On FLX, if one or multiple cells of a multicell fixture are selected, the Output window expands to show you the fixture's individual cells.

The fixture's name, is temporarily replaced by the labels of the cells.


If the cells of a multicell fixture are not all at the same intensity level, the Output Window will display the fixture's highest cell intensity percentage below the fixture's number, followed by a "."
