3. Functions of the built-in “Control” computer
On the Giotto’s input panel, as
well as the power and signal
connectors, there’s also a built-
in “Control” microcomputer
By means of this fundamental
part of the fixture, it’s possible
to carry out all the regulations
necessary for correct installa-
tion, as well as running a test
of all the functions and ena-
bling the operator to “interro-
gate” the fixture about some
very important parameters.
To access the functions, scroll with the Up/Down arrows to the required voce desiderata, then
press ENTER to access the variation (also done with Up/Down) and then confirm the new data
with ENTER.
In working conditions,
appears on the display, showing that the input signal
is DMX and is correctly received. After having modified the parameters “Control” micro-computer,
the display automatically returns to this condition after a few seconds.
When there’s no signal, the flashing message indicates
.
3.1 Start address
Every unit in a DMX chain needs a start address in order to accept only the controls sent to that
specific unit. To address the fixture press ENTER:
will appear on the display,
with the word “Addr” flashing. The Up/Down keys now allow the value required to be entered.
Press ENTER again to confirm the new value.
3.2 Pan direction
This function allows to set the direction of rotation of Giotto’s moving head and is indispensable
when several fixture’s are installed, in order that the operator can have fixtures set opposite each
other moving in the same direction when a command is received. Scrolling the menu with
Up/Down,
or
will appear. To change the direction of
rotation press ENTER and then change from Norm to Rev (or vice versa) with the Up/Down keys,
then press ENTER to confirm the new choice.
3.3 Limiting Pan
The Giotto fixture has a 540° Pan range (one and a half turns). If the total movement is not requi-
red, two parameters enable to limit the start and stop angle. The only limit is the minimum diffe-
rence between start (MIN) and stop (MAX), set at 4°.
