APPENDIX B : ORBITING

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.

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.
