Demux
A device which splits a DMX signal into analogue control signals, for use with older
generation dimmers.
Desk
A commonly used name for the lighting control equipment. Also sometimes known
as Board or Console.
Dimmer
A device which takes a control signal and turns it into a dimmed mains voltage for
controlling the brightness of a standard filament lamp.
DIN
Deutsches Institut für Normung e.V. The MIDI standard specifies the use of
180degree 5 pin DIN plugs.
Dipless
The fades on the Jester are customised so that there will not be a ‘dip’ in the
brightness on stage when crossfading from one scene to another.
Direction
The order in which chase steps are output. This can be forward, backward, bounce
or random.
DMX-512
Standard communications protocol for dimmers and moving heads. 512 channels of
control are digitally multiplexed and sent down a cable to dimmers, which listen for
their specific data, according to their start address.
DMX In
The ability to take a DMX input (see DMX-512) into the Jester, and output it through
the Jester’s DMX output. This allows you to add in the 24 (48) channels of your
Jester to the DMX signal, and also to store the incoming DMX signal as part of a
scene or chase. These can then be replayed as a normal scene or chase, but affect
the entire universe of DMX.
Enter
The key in the middle of the cursor keys which allows you to confirm something on
the Jester.
Fade Down
The Fade Down time on the Jester is the time it will take for the channels which are
programmed at a lower level in the incoming cue to that of the current cue to fade to
their programmed level.
Fade Time Pot
The control for setting fade times on the Jester. This can be used in conjunction with
SHIFT to set a split fade time.
