Mouse Latency Allowance
This option is used during calibration to account for latency delays (caused
as signals pass through a device) introduced by some KVM switches from
alternative manufacturers.
During calibration, the ServSwitch CX waits for 40ms after each mouse movement
before sampling the next. If a KVM 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 default
rate can prove too fast when passed through certain connected KVM switches from
alternative manufacturers. In such cases, data are discarded causing the local and
remote mouse pointers to drift apart. If this effect is encountered, increase the mouse
rate to around 30ms (data are then sent at a slower rate of 33 times per second).

Background Refresh Rate
Use the arrow keys to alter the refresh rate for screen images via remote links. This
allows you to tailor the screen refresh to suit the network or modem connection
speeds. The options are: Slow, Medium, Fast or Disabled. When the disabled
option is selected, the remote users will need to manually refresh the screen.
Note: When a low connection speed is detected, the background refresh is
automatically disabled, regardless of the settings of this option.

Single Mouse Mode Mouse Switch
Allows you to select the mouse button combination that can be used to exit from
single mouse mode (when active).

Behaviour for admin connections when limit reached
Determines what should occur when four global connections already exist and
a fifth, administrator connection attempt is made. Options are: Replace oldest
connection, Replace newest connection and Don’t replace. Only non-administrator
connections can be terminated in this way.

Use VESA GTF
When ticked, the VESA Generalized Timing Formula will be used to help
determine the correct input video resolution and timing details. See

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.
