KVM-0850/1650 IP KVM switch If the problems above happen, please consult your network administrator in order to provide an appropriate network environment. 5.5 Main Window Clicking the Remote Console opens an additional window. It displays the screen content of your host system. The Remote Console will behave exactly the same way as if you were sitting directly in front of the remote system. That means keyboard and mouse can be used in the usual way.
KVM-0850/1650 IP KVM switch Sync mouse Activates the mouse synchronization process. Choose this option to synchronize the local and the remote mouse cursor. This is necessary especially when using accelerated mouse settings on the host system. In general, there is no need to change mouse settings on the host.
KVM-0850/1650 IP KVM switch A user with the appropriate permission can close the Remote Console connections of all other users. No users can open the Remote Console until this user disables the exclusive access, or logs off. A change in the access mode is visible in the status line (see Figure 5-8). Figure 5-8. Remote Console Exclusive Mode • Scaling Allow you to scale down the Remote Console. You can still use both mouse and keyboard, however the scaling algorithm will not preserve all display details.
KVM-0850/1650 IP KVM switch Warning Intelligent Sync takes more time than Fast Sync and requires a correctly adjusted picture. Use the auto adjustment function or the manual correction in the Video Settings panel to setup the picture. • Local Cursor Offers a list of different cursor shapes to choose from for the local mouse pointer. The selected shape will be saved for the current user and activated the next time this user opens the Remote Console.

Soft Keyboard Opens up the Menu for the Soft-Keyboard. • Show Pops up the Soft-Keyboard. The Soft-Keyboard is necessary in case your host system runs a completely different language and country mapping than your administration machine.
KVM-0850/1650 IP KVM switch Figure 5-13. Soft Keyboard Mapping • Local Keyboard Used to change the language mapping of your browser machine running the Remote Console Applet. Normally, the applet determines the correct value automatically. However, depending on your particular JVM and your browser settings this is not always possible. A typical example is a German localized system that uses an US-English keyboard mapping.
KVM-0850/1650 IP KVM switch • Encoding Allows to adjust both compression rate and the colour depth individually. Depending on the selected compression rate the data stream between the KVM-0850/1650 and the Remote Console will be compressed in order to save bandwidth. Since high compression rates are very time consuming, they should not be used while several users are accessing the KVM-0850/1650 simultaneously. The standard color depth is 8 Bit (256 colors).
KVM-0850/1650 IP KVM switch 5.5.2 Remote Console Status Line Status line Shows both console and the connection state. The size of the remote screen is displayed. Figure 5-15 was captured from a Remote Console Screen with a resolution of 800x600 pixels.

KVM-0850/1650 IP KVM switch For additional options see the Section called Options for details. Creating an Image Floppy Images UNIX and UNIX-like OS To create an image file, make use of “dd”. This is one of the original UNIX utilities and is included in every UNIX-like OS (UNIX, Sun Solaris, Linux). To create a floppy image file, copy the contents of a floppy to a file. You can use the following command: dd [ if=/dev/fd0 ] [ of=/tmp/floppy.
KVM-0850/1650 IP KVM switch To create a CDROM image file, copy the contents of the CDROM to a file. You can use the following command: dd [ if=/dev/cdrom ] [ of=/tmp/cdrom.image ] dd reads the entire disc from the device /dev/cdrom, and saves the output in the specified output file /tmp/cdrom.image. Adjust both parameters exactly to your needs (input device etc.). MS Windows To create the image file, use your favorite CD imaging tool.
KVM-0850/1650 IP KVM switch 6.2.3 Drive redirection Warning 1. Drive Redirection is only possible with Windows 2000 and the latter version. 2. The Drive Redirection works on a low SCSI level and the SCSI protocol cannot recognize partitions; therefore the whole hard disk selected will be shared instead of any particular partition. 3. While connecting to a legacy KVM switch, please select PS/2 mouse for Keyboard/Mouse setting from webpage. Otherwise you will be not be able to use Hot-key. 6.2.3.

KVM-0850/1650 IP KVM switch 6.2.4 Options Options Set this option to disable the mass storage emulation (and hide the virtual drive) if no image file is currently loaded. If disabled, no file image will be found. It may happen that the host system will hang on boot due to changes in the boot order, or the boot manager (LILO, GRUB). This case was reported for some Windows versions (2000, XP), other OS might not be fully excluded. This behavior depends on the BIOS version used in that machine.
KVM-0850/1650 IP KVM switch 6.3.2 Users And Groups Figure 6-13. Set User The KVM-0850/1650 comes with 2 pre-configured user accounts that have fixed permissions. The account super has all possible rights to configure the device and to use all functions KVM-0850/1650 offers. The account “user” has only the permission to open and use the Remote Console. Even his user name and password can only be changed by the super account. Upon delivery, both accounts have the password pass.
KVM-0850/1650 IP KVM switch 6.4 KVM Settings 6.4.1 User Console The following settings are user specific. That means, the super user can customize these settings for every users separately. Changing the settings for one user does not affect the settings for the other users. Figure 6-14.
