How to Set DMX Loss Behavior on CEM+

Symptoms

When DMX is unplugged from the console accidentally, the lights powered by the Sensor+ (CEM+) Rack go out immediately, or don't stay on long enough if they remain on.

Explanation of Issue

The CEM+ has data loss behaviors that define what the rack does when signal is lost. The options are below*:

- Wait and Fade: upon loss of the signal, the rack will keep the last look for a designated time and then fade out. The default wait time is 180 seconds, but that can be adjusted to a shorter or longer interval. The minimum is 0 seconds, and longest is 60 minutes.

- Hold Last Look: upon loss of the signal, the rack will hold the last look until either the signal is re-acquired, or if the rack is reset.

- Play Preset: upon the loss of the signal, the rack will play a preset for a designated amount of time, and then fade out. The default wait time is 3 minutes, but can be adjusted to a shorter or longer interval. The minimum is 0 seconds, and the longest is 60 minutes.

Follow the steps below to set up the data loss behavior on your rack.*

  1. Press the + or - button until you see [Rack] on the bottom line of the display. Press the check mark.
