Default Preferences
When an AJA device starts up, a preference can determine what settings it will
have it when it begins to operate. The AJA Control Panel offers two default
preference settings:
• Local Preference - A preference stored from the last AJA device's Control Panel
settings to be used on next startup of AJA Control Panel. This occurs on next
restoration of the default state (triggered by start up of host CPU, startup of
the AJA device, or when a third-party application releases the AJA device).
• Global Preference - A preference saved for use as a global default start state
for an AJA device that can be shared by multiple users, applied on first startup,
or by pressing the Control Panel
Reset Device...
button.
Local Preference
The Local Preference file (com.aja.devicesettings) exists to immediately and
automatically store all parameter changes made by a user on a particular AJA
device. When any control is changed in the Control Panel, that change is recorded
in the Local Preference file stored in a unique location on that computer that is
dedicated to that particular device, serial number, and logged-in user. Then, when
AJA Control Panel is restarted for any reason, the AJA device being controlled
restores the settings being used when Control Panel was last closed.
The Local Preference file can be accessed at the following locations.
On Mac:
• From the Finder, hold down the Option key (to display the Library directory)
and click on Go/Library/Preferences/com.aja.devicesettings.
On Windows:
• C:\Users\<USER_NAME>\AppData\Local\aja\com.aja.devicesettings
NOTE: Clicking on the AJA Control Panel "Erase All Prefs" button deletes the existing
Local Preference file from this location. This file will be recreated as soon as any
Control Panel setting is changed.
NOTE: Clicking on the AJA Control Panel "Reset Device..." button will delete the existing
Local Preference file. If a Global Preference file is found, these settings are
reloaded. If a Global Preference file is not found, “factory defaults” are loaded and
the device is set to that state
Global Preference
An administrator can establish a house standard for an AJA device by copying
a preference file to a shared computer location. Once placed at that location, it
becomes a Global Preference file where it will establish a standard default startup
state for all users of that AJA device using that computer system. These settings
preempt the initial AJA factory default settings, and are applied when an AJA
device is first powered up, or when the Control Panel
Reset Device
button is
pressed.
To establish a Global Preference, the administrator first configures the AJA device
(which automatically creates a "com.aja.devicesettings" Local Preference file in
the location identified above) and then copy or move or that file to the correct
computer locations (manually or by pushing it out across the network) on all the
computers that use the AJA device.
NOTE: If the user makes changes to an AJA Device's Control Panel settings, those
changes are saved to the Local Preference file, which will take priority over the
Global Preference file.
The shared computer locations for a Global Preference file are:
