AVN422HD User’s Manual
Chapter 6 Using the Browser Interface

About User Levels:
There are four possible authorization levels which can be assigned to a given user.
Admin
– The Admin user level has full administrative authorization and can modify all device
parameters, including other users. Note that you can only change the default admin user's
password, and not the Username or Level, and the default admin user cannot be deleted. Other
admin users can be created with different Usernames, but the Default Admin User will always
exist in the list.
Channel
– The Channel user has the ability to configure, update and save any setting in the
Channel pages, including Input, Encoding, Stream, and SAP, as well as the ability to view the
Advanced pages, Events and Stats. All other browser pages (Device and Administration) are
disabled.
Start/Stop
– The Start/Stop user only has the ability to start and stop the device's stream
(including any auxiliary streams). They can also view all the settings on the Channel and
Advanced pages, but cannot configure, update, or save them.
Invalid
– The Invalid user cannot log in to the device. This user level can be assigned to disable
a previously saved user, if deleting the user is not desirable.
6.7.4 Administration FactDef
Clicking the
FactDef
button causes the AVN422HD to reset all of its settings to Factory Default
values, including network settings.
6.7.5 Administration Upgrade
The Administration Upgrade page displays all of the current firmware "image/component"
versions and allows each firmware component to be upgraded independently (refer to
Chapter 8
Field Upgrade
).
Note:
In order to upgrade firmware components, the AVN422HD must have a valid
Gateway IP address configured and be on a network that has access to the
Internet.
The AVN422HD has four firmware components:
1. Root File System
2. Linux Kernel
3. U-Boot Boot Loader (Boot Loader)
4. Configuration Partition (not currently implemented).
Each firmware component must be updated independently, but not all components will always
need to be updated. The Root File System is the most likely to change, and therefore the most
likely to require updating. If two or more image/components need to be updated, the updates
