USING USER MEMORY AND CHANNEL MEMORY (Memory)

Before Using the Memory Function

The projector uses a microprocessor to automatically iden- tify the input signal. Therefore, it is necessary to set and store in the microprocessor the adjustment conditions of such set- tings as the alignments and picture settings that match the input signal and that an optimum picture can be reproduced.

The projector is equipped with five kinds of memory. There is standard memory that cannot be overwritten, user memory to which the user can freely write or overwrite (and to which switcher channels can be registered), special switcher chan- nel memory that is used when this main unit and a number of switchers are connected and used together , the default area in a one-to-one correspondence with areas of the standard memory, and last memory that stores the latest settings for each source (RGB1, RGB2, Video, and S-Video)

Types of Memory

• Standard Memory (Preset at Time of Shipping)

Video signals of the type used in personal computers and work stations currently on the market have been registered in the projector as standard data (and cannot be overwritten). See "Displayable Video Signals" on Page E-82.

When displaying personal computer video signals (resolu- tion/frequency) that have not been registered to standard memory, make the screen and picture adjustments and then register them to user memory.

• User Memory

When data that has been adjusted by the user is stored to user memory, it can be called back and used at any time.

A maximum of 100 items of screen and/or picture adjustment or setting data can be registered.

• Channel Memory

This special memory for switchers is used to simultaneously register the screen adjustment data and the data of the switcher when the projector is used in conjunction with a switcher.

A maximum of 100 channels (10 per switcher with max. of 10 switchers) of setting data (for the various pieces of equip- ment that are connected to the switchers) and the screen and picture adjustment data (adjusted by the projector) can be registered.

• Default Area

This is a rewritable memory that is in a one-to-one corre- spondence with areas of the standard memory.

The projector searches the settings in the default area before the standard memory.

The factory shipped default area settings are the same as in the standard memory.

• Last Memory

This is a memory that stores the last settings for each source (RGB1, RGB2, Video, and S-Video).

Switching sources will store the settings in memory. For this reason, even if the memory is not used, returning to its original source will store the adjustments in memory.

Automatic Searches of Memory

The channel memory is searched first when used with the switcher (s).

When the input is switched, the projector searches the user memory for the existence of applicable registration memory during input selection (of input source) or switcher slot selec- tion (RGB and RGB2 only). When more than one such memory item appear, the most recent memory number is selected. When there is no such memory item, the unit searches irrespective of input selection or slot selection. When there is no applicable memory item in user memory, the default area and a standard memory search is performed in this order (but there will not be a search when there is a skip setting).
