16 ULTRAVIEW REMOTE 2 INSTALLATION AND OPERATIONS MANUAL
Screensaver Timeout
Use the arrow keys to select an appropriate period of inactivity before a screensaver is displayed and the user is
logged out. This setting applies to local users only and once the screensaver is displayed, for security purposes the
user is required to log in again. The timeout period can be selected between 5 minutes and 1 day (24 hours), it
cannot be disabled.
Menu Bar Toggle Hot Key
Use the left or right arrow keys to choose the hot key to turn on or off the menu bar.
(NOTE: DO NOT assign a hot key value that will conflict with other hot key assignments. The KVM switch
module uses hotkeys to quickly perform an operation. Make sure the hot key assigned to toggle the menu
bar is unique)
Encryption
Three encryption options are available; Always on, Prefer off, Prefer on. The one to choose depends on the specific
details of your installation. The use of encryption imposes a slight performance overhead of roughly 10% but is highly
secure against third party intrusion.
Encryption settings
The Unit configuration page offers three encryption settings:
Always on - This setting will force all viewers to use encryption. Note: This setting will preclude any VNC
viewer versions that do not support encryption.
Prefer off - This setting does not enforce encryption unless a viewer specifically requests it. If a viewer has its
‘Let server choose’ setting, then an un-encrypted link will be set up.
Prefer on - This setting generally enforces encryption unless an earlier viewer version is unable to support it,
in which case the link will be un-encrypted. If a viewer has its ‘Let server choose’ setting, then the link will be
encrypted.
The “Advanced Configuration” tab will display advanced options that generally do not need modifying.
Force VNC protocol 3.3
IMPORTANT: The use of this option is not recommended. VNC protocol 3.3 is a legacy version that does not offer
any encryption.
Idle timeout
Determines the period of inactivity on a remote connection before the user is logged out. The idle timeout period can
be set to any time span, expressed in minutes. Note: The Screensaver option serves a similar purpose for local
connections. A value of 0 will disable the timeout.
Protocol timeout
Sets the time period by which responses should have been received to outgoing data packets. If the stated period is
exceeded, then a connection is considered lost and terminated.
