Options
Descriptions
Permission Levels
Determines which Decoders can communicate with which
Encoders. A Decoder must have a permission level that is
equal to or greater than the Encoder in order for
communication to be successful.
KVM Encoders table
Use the KVM Encoders table to:
• Let the Decoder know the Encoder passwords it needs to
establish communication.
• Assign Encoder hotkeys.
• Add/remove Encoders from the Decoder's list.
Passwords
By default, KVM streams are encrypted with a common
password. You can change the password on the Security
page of the Encoder. If you change Encoder passwords, you
will need to supply the new information to the Decoders to
allow communication to continue.
A Decoder only receives password information for the
Encoders on the network that have been associated with
that Decoder as mentioned previously.
Hotkeys
To use hotkeys for easy switching, enable KVM Directory
Screen Enable on the Decoder's KVM page. You can now
access the KVM Directory Screen at any time by pressing the
<Scr Lk> button (two or three times) on the keyboard
connected to the Decoder. This screen displays all Encoders
associated with that Decoder and their corresponding
hotkeys.
Import and export KVM CSV
Multiple Encoders and Decoders can be configured from a
files
single CSV file (which is generated using the KVM Wizard in
N-Able). Once all changes are made, upload the file to each
unit using its KVM page.Click the Choose File button,
browse to the CSV file you exported from the wizard, and
click the Upload button.
Warning! You must assign KVM passwords to your Encoders and Decoders (as well as
change the default login password from admin/password) in order for your system to
be secure.
