Click this button to display advanced options that do not normally require alteration.
Force VNC Protocol 3.3
IMPORTANT: Protocol 3.3 is a legacy version that does not offer any encryption.
Hashed passwords are not supported with 3.3
Idle Timeout
Determines the period of inactivity on a global connection before the user is logged
out. The idle timeout period can be set to any time span, expressed in minutes.
Session Sleep Timeout
Determines the period of inactivity before the viewer screen will blank and a
message is displayed. When no hosts are being viewed either because of this
time out or if no viewers are active then parts of the video circuitry are powered
down reducing power consumption by up to a third.
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.
Background Refresh Rate
Use the arrow keys to alter the background refresh rate used to correct any
screen changes missed in normal operation. The options are: Slow, Medium,
Fast, Auto or Disabled. The Auto option automatically varies the refresh rate
when multiple VNC sessions are active to provide a balance between the
sessions.
Note: When a low connection speed is detected, the background refresh is
automatically disabled, regardless of the settings of this option.
Mouse Latency Allowance
This option is used during calibration to account for latency delays that may be
caused as signals pass through a device.
During calibration, the ALIF 2112T waits for 40ms after each mouse movement
before sampling the next. If a device adds a significant delay to the flow of data,
the calibration process can be lengthened or may fail entirely. The value entered
here is added to (or subtracted from) the default 40ms sampling time.
Note: You can enter negative values (down to -40) in order to speed up the
calibration process when using fast KVM switches. Use this option with caution
as it can adversely affect the calibration process.
Mouse Rate
Defines the rate at which mouse movement data are transmitted to the system. The
default option is 20ms, which equates to 50 mouse events per second. This is used to
slow down the rate in exceptional circumstances but normally requires no adjustment.
Single Mouse Mode Mouse Switch
Select the mouse button combination to exit from single mouse mode (when active).
Use Quick Mouse Calibration
Invokes optimised calibration techniques that handle the majority of mouse types.
Behaviour for admin connections when limit reached
Determines what should occur when the limit on VNC users is reached. Options
are: Replace oldest connection, Replace newest connection and Don't replace.
Only non-administrator connections can be terminated in this way.
Enable Virtual Media
When ticked, allows the Adder Virtual Media features to be used.
Reset Unit
Performs a complete cold boot of the ALIF 2112T unit.
