Cause

When connecting to a server via a Digital IP KVM, you may notice that the local mouse (your desktop) is not synchronizing with the remote mouse (the workstation/server that you are attaching to). There are a couple of steps that you can take to resolve this, depending on the KVM you are using.



Resolution


Recommended options and tweaks for KVM1116P, KVM2116P, and KVM2132P

• Try enabling mouse sync mode which is an icon option available from the Remote Viewer Toolbar.
• From the same toolbar, it is recommended to try and set the Network Type to 512K ADSL under Video Settings. 
• Consider changing the mouse mode between single, dot, dual, crosshair options along with enabling/disabling mouse sync between each of the mouse modes. (This is also accessible from the Remote Viewer Toolbar.)
• Make sure "Cable Length" is set accurately for your configuration. The available options are short, medium, and long. (This is also accessible from the Remote Viewer Toolbar.)

Recommended options and tweaks for AP5610, AP5615, AP5616
 

• Connect to a server via the Digital IP KVM. Once connected to the target server via the IP KVM's Java viewer, select Tools, then Single Cursor mode to sync your mouse with the target server's.

Recommended options and tweaks for AP5405
 

• If using an AP5405, connect to a server via the IP KVM. Once connected, scroll to the top of the server window. You should see the following menu options: Shortcuts, Options, Connection, Host OS, About.... Choose Options, then Auto Sync Mouse.

You can also try adjusting mouse settings direct from the attached servers (i.e. mouse acceleration) if the mouse is not working correctly (meaning the servers attached to the KVM, not the server you're connecting from).
