This function also allows to optimize Giotto 1500 moving head in relation
to the operator's position, in order to simplify all positioning procedure.
When PAN TILT SWAP is enabled (ON), this means that the lighting console
sends the data regarding Pan to the Tilts controls and vice versa.
To invert Pan and Tilt movement proceed as follows:
1. Use the DIAL to find "SWAP".
2. Press ENTER to confirm. The message on the display will start to flash.
3. Use the DIAL to select which of the two available options is required.
4. Press ESC to confirm.
This function allows to define the movement resolution (16 or 8 bit). The
difference is in the number of steps in which the range of head movement
is divided.
In high res. (16bit) mode, 530° ofl pan and 250° of tilt are divided into
65.536 steps, ensuring very smooth precision even at very low speed. In
low res. (8 bit) mode the number of the steps is 256, which nevertheless
allow precise movement. The change from high res. into low res. reduces
the number of channels.
1. Use the DIAL to find "PAN TILT RES" menu.
2. Press ENTER to confirm. The message on the display will start to flash.
3. Use the DIAL to select the required resolution.
4. Press ESC to confirm.
There are two ways to control the speed with which a fixture moves from a
static position into another.
These are known with the names of "TRAKING contol" and "VECTOR
control" and are determined by the presence of the Pan/Tilt Speed
channel.
In TRACKING mode the speed is determined by the cross-fade time set on
the console.
In VECTOR mode the speed is set by the Pan7Tilt Speed channel directly,
the cross-fade time in the consol has to be 0.
The change from high res. into low res. reduces the number of channels:
1. Use the DIAL to find "SPEED CONTROL" menu.
2. Press ENTER to confirm. The message on the display will start to flash.
3. Use the DIAL to select the required control speed.
4. Press ESC to confirm.
