Starting the Equipment
1. Hang up of Varyscan
®
To scoop the optimal functioning of your Varyscan
®
, you should hang up the spots as high as possible.
2. Adjustment of Varyscan
®
All spots should hang in the same angle, i.e. the imagined angle between perpendicular and Varyscan
®
should
be the same among all Varyscans
®
3. Cabling of Varyscan
®
Power supply:
A specialist should attach a plug to the open end of the connecting cable, or have the cable connected to 230
volt 50 hertz.
DMX-cabling:
Connect the output of your DMX-controller with the first Varyscan
®
(controller DMX-out; Varyscan
®
DMX-in) with
the aid of a 5pole XLR-cabel. Now establish the connection between the Varyscans
®
with the aid of further
5pole XLR-cables. Make sure that in DMX-out of the last Varyscan
®
there is a resistor (XLR-plug with a resistance
of 100 Ohm between pin 2 and pin 3) plugged into.
4. Adjustment at DIP-switches
At DIP-switch No.1 and No.2 you have the following possibilities of adjustment:
?
initialisation mode
?
test mode
?
infinitely variable colour changing
