Setup Menu
Note that transition times are specified for switching applications with Auto
Acquire turned OFF. When Auto Acquire is ON, the transition time is greater,
due to the additional time required to analyze the input video timing.
Transition values are listed below:
• Adjustment range: 0.0 - 12.0 seconds (0.0 is a cut)
• Default: 1.0 seconds

The Auto Acquire function enables or disables the Input > “Auto Acquire“mode, which
acquires a signal for the input. Values for Auto Acquire are: ALLOFF, ALL ON (default),
and Input.
When Auto Acquire is ALL ON, and an input has a saved configuration file, the system
attempts to use the saved file. If the input timing matches the timing in the saved
configuration file, the saved file is used.
The system always performs a full sync (timing) acquisition on the selected input signal
under the following conditions:
• When an input without a saved configuration file is selected
• When the input type is changed
• When the input signal’s sync rate is changed
• When an input with a saved configuration file is selected, but the input timing is
different from the saved configuration
When Auto Acquire is ALL ON, and the input source is non-digital, the system uses the
following library search order:
• Saved configuration files defined in the File Association Menu for each input
channel
• The user’s library of saved files
• A best guess
When Auto Acquire is ALL ON, and the input source is digital, the system uses the
following search order:
• Saved configuration files defined in the File Association Menu for each input
channel
• The user’s library of saved files
• Direct measurement of the signal
If the input signal’s timing is too different from the saved configuration, a good lock may not
be possible. In this situation, the “Invalid Signal” message is displayed, and the video
output will be black. You will also see “Invalid Signal” if the configuration file for an input
has been deleted.
When Auto Acquire is INPUT, Auto Acquire can be adjusted to be ON or OFF on an Input
by Input basis within the Input setup menu.
Please note the following important points:
• It is recommended that you leave the Auto Acquire mode ALL ON. Then, if the
timing changes on any input (whether or not you have a saved config file), you will
always get an output image. On the other hand, if the mode is ALLOFF and the
input timing changes, the output will be black.
