Lindy MC5-IP manual Advanced unit configuration

Advanced unit configuration

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

To get here

1Using 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 3.3

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.

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 MC5 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 Appendix 9 for a list of all supported video modes.

Upgrade firmware

Places the unit into upgrade mode. See Upgrading MC5-IP models.
