This video provides an overview of the Test Mode feature onboard the Force 1.0. This mode allows you to scan through your lighting rig, one fixture at a time or one pixel at a time, in order to confirm/verify your lighting rig and DMX Universe profile are both setup correctly.
In the case of a fixture being mounted in reverse (a bar light, for example), resulting in pixels being displayed in the incorrect order, there is a simple fix without having to get up on a ladder.
