Cue list
The cue list offers a way to playback cues in a pre-determined order. The cue list may be
synchronized to internal PC clock for elapsed time between cues or to time code from a CD-ROM
drive or Windows Media files. It can also be executed manually using a 'go-button', if for example used
in a theatrical type of show where everything is planned and pre-programmed.
See cue list control for more details
The current sequence
It is important to understand that the LightJockey always contains a 'current sequence'. Think of the
current sequence as a 'holder' for sequences when editing a sequence. When saving a sequence, it is
always the current sequence that is being saved, and when loading an already saved sequence, the
sequence is being loaded 'into' the current sequence for editing.
In principle the current sequence always contributes to the final DMX output of the LightJockey -
however if the current sequence does not contain any 'instructions' (for example after a New Sequence
command has been executed) there will be no visible effect of the current sequences contribution to
the overall output.
The current cue
In the same way as the current sequence the LightJockey always have a current cue. The current cue
acts as a 'holder' for cues when editing, and when playing back cues, it is always done by loading
cues into the current cue. As with the current sequence, the current cue always contributes to the
final DMX output, but if the current cue contains no 'instructions' (no sequences or other elements) -
there will be no visible effect.
DMX addresses and links
DMX Addresses
To enable communication between the LightJockey and the fixtures, an address must be assigned to
each fixture. This address must also be set on the fixture itself - Martin fixtures has DIP-switches or
LED display panels for address settings.
When assigning DMX addresses keep in mind that fixtures usually uses several continuous
addresses, for example the Roboscan 918 uses 16 addresses. The first address is usually referred to
as the start-address. This is important to remember since it is not possible to 'share' addresses
between individual fixtures, so if the Roboscan 918 was given the start-address of 1, the next available
address would be 17 (1+16).
The DMX protocol defines a maximum of 512 addresses (or channels) so all fixtures must fit within
this address space.
There are two ways to assign an address to a fixture in LightJockey.
Set the address manually.
Use the address field in the upper right hand corner of the fixture configuration dialog. Use this method
to match addresses on fixtures that has already been given an address (on the fixture).
Use the "Auto Address" function.
This will prompt LightJockey to calculate addresses based on the fixtures selected and fixtures that
has already been assigned an address. Use this approach when fixtures have not yet been addressed
(on the fixture). There are a few exceptions where the auto address will not work - see details in the
Fixture Configuration help topic.
Link
Link is a term that describes the physical connection from the controller to the fixtures (and between
the fixtures). Since the DMX protocol allows only 512 channels on one link, the only way to add more
channels to a system is to increase the number of links (physical connections). Depending on what
DMX transmitter hardware is in use in the installation, one or more links may be available for
connecting fixtures. Links are numbered 1-4 and when addressing the fixtures, make sure to specify
