2.7.2 About ASI and ASR
ASI (Automatic Source Interpolation) is a feature which automatically adjusts display settings based on the
settings of other setup memories stored in the projector. When a setup memory is first created, ASI automatically
generates its initial display settings. These settings will be created by copying another setup memory or by
interpolating multiple setup memories.
ASI is activated when:
•
A new setup memory is created.
•
An ASR is performed and its logic has activated an ASI.
•
An "ASI with Save" is specified by the user (see Section 3.6).
ASR (Automatic Source Recall) is a feature which, when turned on for a given input, provides automatic Recall
memory selection or ASI adjustment. ASR processing can activate when:
•
a change in scan frequencies is detected at the input,
•
an input is selected,
•
a Recall memory is selected, or
•
a channel is selected.
This feature is primarily intended for use when many different sources must share the same input (via a third party
switcher, for example) or when a signal source can output several different scan frequencies (e.g., a SVGA card).
When a source switch is made, the projector may automatically select a Recall memory with matching scan
frequencies or create the display settings based on the settings in other setup memories.
2.7.3 Input
Memory
Setup
Follow these steps to prepare an Input memory for a source.
Note:
To assure proper setup of an existing Input memory, ASR must be off (default) for the memory.
Step 1.
Connect the source to the input to be set up, and then select the input using the Source
command. For example, if the source is connected to slot 1 of the projector, press [
SOURCE
]
[
0
] [
1
]. If the Input memory did not previously exist, it will be created automatically.
Step 2.
The source should be displayed on the projection screen. If much adjustment is required,
press [
UTIL
] [
1
] [
2
] to perform an ASI with Save. The display appearance may improve
based on the settings stored in other setup memories. (If the Input memory is new, ASI with
Save will have
Step 3.
Make display adjustments as required. Adjustment changes will automatically be saved in the
2.7.4 Recall Memory Setup
Follow these steps to prepare a Recall memory.
Step 1.
Select the input connected to the source. For example, if the source is connected to switcher
1, slot 5, press [
SOURCE
] [
1
] [
5
]. The source should be displayed on the projection screen.
Step 2.
To assure proper setup of a Recall memory, ASR must be off (default) for the current input.
Step 3.
Select a Recall memory as the current setup memory. For example, to make Recall memory
03 the current setup memory, press [
RECALL
] [
0
] [
3
]. If the Recall memory did not
previously exist, it will be created automatically.
Step 4.
If much adjustment is required, press [
UTIL
] [
1
] [
2
] to perform an "ASI with Save". (If the
Recall memory is new, ASI with Save will have already been performed when the memory was
Step 5.
Make display adjustments as required. Adjustment changes will automatically be saved in the
Recall memory.
