Advanced unit configuration

Click this button to display several 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 remote 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.

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 connections speed is detected, the background refresh is automatically disabled, regardless of the settings of this option.
