Adjustment Blocks and Source Numbers 90-99A-15976066 BARCOCINE 7 011299Adjustment 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 numericvalues. These numeric values are used to control digital potentiometers which in turn, control the projector. Each source connectedto the projector has a unique set of adjustment data which is automatically downloaded into the projector’s digital potentiometers oncethe 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 modeis entered. If other sources have already been connected to the projector and geometry and convergence adjustments have beenperformed on these sources, the projector will use Linear Digital Interpolation to create a new block for the new source. This blockwill 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 headerand the data representing the values for all adjustments (eg. Convergence and Geometry) in the projector for the source the blockcorresponds to. The block header contains the basic characteristics of the source and the projector configuration used to displaythe source.Built up of blockBlock Headerexample of block headerBlock Number 01Source Number 01Horizontal Frequency 15.6 kHzVertical Frequency 50 HzInput Type videoScan Switch Configuration Front/CeilingThe data representing the various adjustments for the source follows the block header.A ADJUSTMENT BLOCKS AND SOURCENUMBERS 90 - 99Source numbers 90 - 99Why used ?Source numbers 90 - 99 do not correspond to physical inputs to the projector or RCVDS. They are used to assign an additionaladjustment block to a source. This additional adjustment block may contain different geometry and convergence settings, sync fast/slow positions and enhanced blue on/off settings. The relationship between source numbers 0 - 9 and 90 - 99 (projector with RCVDS)or 1 - 5 and 91 - 95 (stand-alone projector) is shown in the diagram below.The alternate adjustment block for sources 0 - 9 (projector with RCVDS) or 1 - 5 (stand-alone projector) is activated by selectingthe corresponding source number 0 - 9 (projector with RCVDS) or 1 - 5 (stand-alone projector). 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 adjustmentblock 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 iscopied 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 secondadjustment block.4. Exit the adjust mode.Note : the above also applies to source number 1 - 5 and 91 - 95 of a stand alone projector (no RCVDS) |
