Configuring a fixture with MUM
Setting the clock
Exterior 400 Image Projector fixtures have a battery-operated 24-hour clock that is used to start and stop
stand-alone operation.
To set the clock:
1. Click on the Fixture Info button in MUM:
Figure 11: Fixture info window
2. Using the Fixture real-time clock spin buttons, set the fixture to the current time (expressed in the
24-hour clock in hours and minutes) and date. The time will be updated in the fixture in real time.
DMX address and other fixture settings
If individual control of each Exterior 400 Image Projector fixtures is required, each fixture must be set up to
receive instructions from the DMX controller on a group of DMX channels that are not used by any other
device in its DMX universe. The DMX address, also known as the control address or start channel, is the
first of these channels. Each fixture uses this channel and the channels immediately above it to receive
instructions.
Exterior 400 Image Projector fixtures use nine DMX channels. If a fixture's DMX address is set to 1, it will
use channels 1 - 9. Channel 10 will be available as the DMX address for the next fixture, which can use
channels 10 - 18, and so on.
If two or more identical fixtures are set up with the same DMX address and in the same DMX mode, they will
receive the same instructions and behave identically. Setting up identical fixtures with the same address is
a good tool for troubleshooting unexpected behavior and an easy way to achieve synchronized action.
