in client fixtures are synchronized with the scene change times in the host. Every time the host changes to
its next pre-programmed scene, the client fixtures change to their next pre-programmed scene at the
same time.
Note the following:
•
Although scene changes in host and client fixtures all occur at the same time, scenes do not have to be
identical. You can program different effects in the standalone scenes of different fixtures.
•
Each fixture displays its own pre-programmed standalone show until it reaches its last scene, then it starts
the show sequence again and continues in a loop. If all fixtures have the same number of scenes in their
shows, they will all start shows in synch. If the standalone shows in different fixtures have different numbers
of scenes, the fixtures will restart their shows at different times relative to each other.
•
If no controller is connected to the first fixture on the link, you can improve the quality of the data signal sent
to client fixtures by inserting a DMX termination plug (a plug with a 120 Ohm resistor across data hot and
data cold) in the data IN connector of the first fixture.
•
DMX and RDM signals will override standalone operation in both the host and the client fixtures. This
means that standalone operation is only possible if no DMX signal is present.
•
If you want host/client operation, set only the first fixture on the link to HOST. Set all the other fixtures to
CLIENT. If you set more than one fixture to act as host in host/client operation, fixtures may behave
unexpectedly.
•
You should set
only one
fixture to HOST when you set up host/client operation, but note that if you want
fixtures to keep obeying the last DMX command they received or to switch to their own independent
standalone show if they stop receiving a DMX signal, you must set
all fixtures to be HOST. Fixtures set to
CLIENT will always black out when they are not receiving a DMX signal or a signal from a HOST fixture.
Setting up host/client operation
To operate fixtures in host/client mode, the fixtures must be connected as described under ‘Control data
link’ on page 17. The host fixture must be programmed to run a standalone routine as described under
‘Programming a standalone show’ on page 20.
Enable host/client operation as follows:
1. On each fixture, access the control menu and select FIXTURE CONFIG. Press ENTER.
2. Select DMX STATE and press ENTER.
3. Select SHOW MODE and press ENTER.
4. Select HOST/CLIENT from FIXTURE CONFIG menu and press ENTER.
5. The default setting is CLIENT. On one fixture only, select HOST and press ENTER. Press MENU to
exit.
6. On all other fixtures, select HOST/CLIENT and confirm that they are set to CLIENT. Press MENU to
exit.
7. Check that no DMX control signal is present.
DMX mode
Four DMX control modes are available: see ‘DMX settings’ on page 19.
Dimmer curve
Four dimming options are available:
•
OPTICALLY LINEAR: dimming appears linear as DMX values change.
•
SQUARE LAW: dimming is finer at low levels and coarser at high levels.
•
INVERSE SQUARE LAW: dimming is coarser at low levels and finer at high levels.
•
S-CURVE: dimming is finer at high and low levels, and coarser at medium levels.
