Mouse Latency AllowanceThis option is used during calibration to account for latency delays (causedas signals pass through a device) introduced by some KVM switches fromalternative manufacturers.During calibration, the AdderView CATx waits for 40ms after each mousemovement before sampling the next. If a KVM device adds a significant delay tothe flow of data, the calibration process can be lengthened or may fail entirely. Thevalue 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 thecalibration process when using fast KVM switches. Use this option with cautionas it can adversely affect the calibration process.Mouse RateDefines the rate at which mouse movement data are transmitted to the system. Thedefault option is 20ms, which equates to 50 mouse events per second. This defaultrate can prove too fast when passed through certain connected KVM switches fromalternative manufacturers. In such cases, data are discarded causing the local andremote mouse pointers to drift apart. If this effect is encountered, increase the mouserate to around 30ms (data are then sent at a slower rate of 33 times per second).Background Refresh RateUse the arrow keys to alter the refresh rate for screen images via remote links. Thisallows you to tailor the screen refresh to suit the network or modem connectionspeeds. The options are: Slow, Medium, Fast or Disabled. When the disabledoption is selected, the remote users will need to manually refresh the screen.Note: When a low connection speed is detected, the background refresh isautomatically disabled, regardless of the settings of this option.Single Mouse Mode Mouse SwitchAllows you to select the mouse button combination that can be used to exit fromsingle mouse mode (when active).Behaviour for admin connections when limit reachedDetermines what should occur when four global connections already exist anda fifth, administrator connection attempt is made. Options are: Replace oldestconnection, Replace newest connection and Don’t replace. Only non-administratorconnections can be terminated in this way.Use VESA GTFWhen ticked, the VESA Generalized Timing Formula will be used to helpdetermine the correct input video resolution and timing details. See Appendix 9for a list of all supported video modes.Upgrade firmwarePlaces the unit into upgrade mode. See Upgrading AdderView CATx IP models.To get here1 Using VNC viewer or a browser, log on as the ‘admin’ user.2 Click the ‘Configure’ button in the top right corner.3 Click the ‘Unit configuration’ option.4 Click the ‘Advanced unit configuration’ option.Force VNC Protocol 3.3IMPORTANT: The use of this option is not recommended. Protocol 3.3 is a legacyversion that does not offer any encryption.Idle TimeoutDetermines the period of inactivity on a global connection before the user is loggedout. 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 TimeoutSets the time period by which responses should have been received to outgoingdata packets. If the stated period is exceeded, then a connection is consideredlost and terminated.
