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

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.
n
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.
