4. Operation
Using the Main Menu
få=^ìíç=^ÅèìáêÉ
From the Main Menu, select In Auto Acquire to enable or disable the Input Auto Acquire
mode. Values are: OFF and ON (default).
• When Input Auto Acquire is ON, the system always performs a full sync
acquisition on the selected input signal under the following conditions:
~ When an input channel without a saved configuration file is selected.
~ When the input type is changed.
~ When the input signal changes sync rates.
~ When an input with a saved configuration file is selected, but the input
timing is different from the saved configuration.
• When Input Auto Acquire is OFF, the system uses the last known configuration
for each input channel, to the greatest extent possible. At some point, the input
signal may be too far away from the saved configuration, in which case a good
input lock may not be possible. In this situation, the "Invalid Signal" message is
shown, and the video output will be black.
Please note the following important points:
• It is recommended that you leave the In Auto Acquire mode ON. In this mode, if
the timing changes on any of your inputs (whether or not you have a saved
configuration file), you will always get an output image. On the other hand, if the
mode is OFF and the timing of an input changes, the output will be black.
• When the In Auto Acquire mode is ON, the ACS-2048 automatically detects and
acquires the input video type and resolution (in most cases), and limits menu
selections as applicable to the detected video type (e.g., color space).
• If you are an advanced user and you know the exact timing parameters for your
input(s), you can turn the In Auto Acquire mode OFF, and dial in your timing
parameters manually.
Tip
If you have already saved configuration files for your input
sources, it is recommended that you turn the In Auto
Acquire mode OFF. This mode provides the fastest
transition times. When the mode is ON, transition times will
be greater, due to the additional time required to analyze the
input timing for each selected source.
