Setting DMX Addresses
To set a DMX address using MUM, click on the
Fixture settings
button and use the
DMX Address
spin
buttons to set the fixture’s DMX address. The DMX address will be updated in the fixture in real time.
DMX reset
Three settings are available in
DMX Reset
:
•
On
– The fixture will accept a reset command sent via DMX on channel 9 (the “Fixture control settings”
channel: see page 35). This can be a useful ‘escape route’ if you have had problems programming the
fixture correctly or a minor software problem has occurred.
•
Off
– Resetting via DMX is disabled to prevent accidental resets.
•
5 Sec
– A reset command sent on DMX channel 9 must be sent for five seconds to reset the fixture.
Dimming curve options
The
Dimming Curve
setting provides four dimming options (see Figure 13):
•
Linear
– Optically linear: the increase in light intensity appears to be linear as DMX value is increased.
•
Square Law
– Light intensity control is finer at low levels and coarser at high levels.
•
Inverse Square Law
– Light intensity control is coarser at low levels and finer at high levels.
•
S-Curve
– Light intensity control is finer at low levels and high levels and coarser at medium levels.
