DMX Test allows users to temporarily set a dmx channel or group of dmx channels to a custom "value" as set in the scroll box at the top of the window when the coordinating cells are selected in the dmx output window:
Toggle on the button at the top of the dmx output window.
Select any dmx channel cell or group of dmx channel cells in the DMX output window spreadsheet.

The dmx test feature can be used to perform a traditional "dimmer check" by toggling on the button in the dmx output window, selecting a dmx channel cell in the spreadsheet, and using the cursor left and right keys to go through the dmx channels for that universe. |
