Advanced unit configuration

Click this button to display advanced options that do not normally require alteration.

Force VNC Protocol 3.3

IMPORTANT: The use of this option is not recommended. Protocol 3.3 is a legacy version that does not offer any encryption.

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. Note: The Screensaver option serves a similar purpose for local connections.

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.

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.

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.

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 AdderView CATxIP 5000 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 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 Appendix 10 for a list of all supported video modes.

Upgrade firmware

Places the unit into upgrade mode. See Upgrading AdderView CATxIP 5000 models.
