ADJUSTMENT BLOCKS AND SOURCE NUMBERS 90-99

Adjustment Blocks (Memory Blocks)

What are adjustment block?

As the projector is digitally controlled, all geometry and convergence adjustments are stored in the projector’s memory as numeric values. These numeric values are used to control digital potentiometers which in turn, con- trol the projector. Each source connected to the projector has a unique set of adjustment data which is automati- cally downloaded into the projector’s digital potentiometers once the source has been selected. This set of adjustment data is referred to as an “adjustment block”.

An adjustment table is automatically created for a source when the source is first connected to the projector and the Adjustment mode is entered. If other sources have already been connected to the projector and geometry and convergence adjustments have been performed on these sources, the projector will use Linear Digital Interpolation to create a new block for the new source. This block will provide an initial set of adjustments for the new source that have been calculated by the projector from “previous experience”.

The projector’s memory has the capacity to store 32 adjustment blocks. The adjustment block consists of two parts, the block header and the data representing the values for all adjustments (eg. Convergence and Geometry) in the projector for the source the block corresponds to. The block header contains the basic char- acteristics of the source and the projector configuration used to display the source.

Source Numbers 90-99

Why used?

Source numbers 90 - 99 are used to assign an additional adjustment block to a source. This additional adjust- ment block may contain different geometry and convergence settings, sync fast/slow positions and enhanced blue on/off settings. The relationship between source numbers 1 - 5 and 91 - 95 is shown in the diagram on the next page. The alternate adjustment block for sources 1 - 5 is activated by selecting the corresponding source number 1 - 5. Once this source number is selected, the alternate block of adjustment data is in use and may be modified via the adjust mode of the projector. The alternate adjustment block is automatically stored.

How to create a second block?

Follow the steps below to create a second adjustment block for a source between 0 and 9.

1.Select the source between 0 and 9 that the second adjustment block is to be created for.

2.Select the corresponding source number between 90 and 99. The adjustment block for the source number between 0 and 9 is copied to the corresponding source number between 90 and 99.

3.Enter the adjust mode and make any desired changes (geometry, convergence, sync fast/slow, enhanced blue on/off) to the second adjustment block.

4.Exit the adjust mode.
