Remote Console Preview Click on Click to open to start the remote console redirection Click on Refresh to refresh the picture. 4.2.
KVM over IP Module 4.3 The Remote Console The Remote Console is the redirected screen, keyboard and mouse of the remote host system that IP-KVM controls. The Remote Console window is a Java Applet that tries to establish its own TCP connection to the IP-KVM. The protocol that is running over this connection is neither HTTP nor HTTPS, but RFB (Remote Frame Buffer Protocol). As default, RFB tries to establish a connection to TCP port number 443.
KVM over IP Module to keyboard and mouse actions with a slight delay. The delay depends on the bandwidth of the link to which you use to connect to the IP-KVM. With respect to the keyboard, the very exact remote representation might lead to some confusion as your local keyboard changes its keyboard layout according to the remote host system.
KVM over IP Module Sync mouse Activates the mouse synchronization process. Choose this option in order to synchronize the local with the remote mouse cursor. This is especially necessary when using accelerated mouse settings on the host system. In general, there is no need to change mouse settings on the host.
KVM over IP Module If a user has the appropriate permission, he or she can force the Remote Consoles of all other users to close. No one can open the Remote Console at the same time again until this user disables the exclusive access, or logs off. A change in the access mode is also visible in the status line. Figure 4-4 Remote Console Exclusive Mode • Scaling Allow you to scale down the Remote Console.
KVM over IP Module Fast Sync -The fast synchronization is used to correct a temporary, but fixed skew. Intelligent Sync -Use this option if the fast sync does not work or the mouse settings have been changed on the host system. Warning This method takes more time than the fast one and requires a correctly adjusted picture. Use the auto adjustment function to setup the picture. • Local Cursor Offers a list of different cursor shapes to choose from for the local mouse pointer.
KVM over IP Module Figure 4-6 Remote Console Options Menu:Cursor • Video Settings Opens a panel for changing the IP-KVM video settings. IP-KVM features two different dialogs, which for adjusting the video settings. Video Settings through the HTML-Frontend To enable local video port, select this option.

KVM over IP Module be packed and sent from IP-KVM, for saving network bandwidth. This function is mainly used for troubleshooting purpose where some old video fragments are displayed as not updated in time for some reason; for example, noise filter for VGA is setting too large. • Soft Keyboard Figure 4-8 Soft Keyboard Opens up the Menu for the Soft-Keyboard. Show Pops up the Soft-Keyboard.
KVM over IP Module • 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. In this case you have to change the Local Keyboard setting to the right language, manually.
KVM over IP Module The option "Video Optimized" has its advantages if transferring high-quality motion pictures. In this case the video compression is disabled, completely and all video data is transferred via network as full-quality video snippets. Therefore, a high amount of bandwidth is required to ensure the quality of the video picture. Figure 4-11 Encoding Compression The next two options allow you to set the compression level to a predefined level OR to set a level for "lossy" compression.
KVM over IP Module Figure 4-13 Lossy Compression Color Depth: Set the desired color depth. You may select between 8 or 16 bit for Video Optimized/compression level 0, or between 1 and 8 bit for compression level 1 to 9. The higher the color depth, the more video information has to be captured and to be transferred.
KVM over IP Module Note: If displaying motion pictures on a connection with low speed you may achieve an improvement regarding the video transfer rate by lowering the color depth and disabling the option "Video Optimized". As a general result, the data rate is reduced (less bits per color). Furthermore, the OPMA module will not have to do any video compression. In total, this will lead to less transfer time of the motion picture. 4.3.
