Orbiting (option)
Static pictures are very often shown on large screen projectors, especially in
process control and presentation applications.  Due to the fact that the same picture
information is shown for a long period on the same place, picture tubes can be
damaged by 'local burn-in'.  To avoid this problem, BARCO has designed special
Orbiting circuitry which moves the picture very slowly around a predefined screen
area.  The orbiting circuitry has been designed using a very long cycle time to make
the movement of the projected image imperceptible.
Adjustment procedure :
The orbiting path is automatically added to the Random Access Adjustment mode
menu when installed.
Press  ADJUST to enter the Ad-
justment mode and select Ran-
dom.
The Random Access Adjustment
Mode menu will be displayed.
Highlight ORBITING with the con-
trol disk and press ENTER.
ENTER continues to the Master Orbiting
menu.
EXIT returns to the Operational mode.
ADJUST returns to the Operational mode.
Orbiting mode toggle switches
The orbiting module is provided with a three pin connector for connection with the
BARCO's BCl link option module, used in multiple projector installations.  For
Orbiting, one projector operates as master whereas the others operate as slave.
