Keybd layout

Use the arrow buttons to match the keyboard layout expected by the host system.

Admin password

Enter the password that will be used to gain administrator access to the CPU IP. There can only be one admin user and only that user is given access to the configuration menus. The admin password background will be red until a reasonably secure password has been entered, although this is only advisory as any password or no password may be entered.

Unit name

The name entered here will be displayed on the local menus and the remote VNC/browser windows.

Hot keys

Use the left and right arrow keys to select an appropriate hot key sequence for the locally connected keyboard. This sequence is used in combination with other keypresses to access the on-screen menus and to change between hosts. The options are: Ctrl+Alt (default), Ctrl+Shift, Alt+Shift, Alt Gr, Left + Right Alt, Left Ctrl + Alt or Right Ctrl + Alt.

Screensaver

Use the left and right arrow keys to select an appropriate period of inactivity on the local keyboard or mouse before a screensaver is displayed and the user is logged out. This setting applies to local users only and once the screensaver is displayed, for security purposes the user is required to log in again. The timeout period can be selected between 5 minutes and 1 day (24 hours), it cannot be disabled. Note: The Idle timeout option serves a similar purpose for remote connections.

Time and date

Use the left and right arrow keys to select the correct time and date. The time entry uses the 24 hour clock notation. The internal real time clock will continue to run for roughly one week without power to the CPU IP, after that it will be lost and require resetting. Use the up and down arrow keys to move between each of the sections within the time and date entries.

Encryption

Three options are available: Always on, prefer off, prefer on. The one to choose depends on the specific details of your installation - see Encryption settings for details. The use of encryption imposes a slight performance overhead of roughly 10% but is highly secure against third party intrusion.
