A short description of the options as follows. • Monitor Only Toggles the Monitor only filter on or off. If the filter is switched on no remote console interaction is possible, and monitoring is possible.
KVM over IP Module • 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. When you designate 25%, 50%, or100% scaling, the size of Remote Console window is calculated according to the remote host video setting with scaling algorithm execution. When you designate “Scale to fit”, the remote video displaying is scaled to fit the size of Remote Console window.
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 The option Noise Filter defines how IP-KVM reacts to small changes in the video input signal. Turning on the noise filter can help reduce video flickering that is often caused by distortions, as well as lowering unnecessary bandwidth consumption. A large filter setting needs less network traffic and leads to a faster video display, but small changes in some display regions may not be recognized immediately.
KVM over IP Module Phase Defines the phase for video sampling, used to control the display quality together with the setting for sampling clock. Horizontal Position Use the left and right buttons to move the picture in horizontal direction while this option is selected. Vertical Position Use the left and right buttons to move the picture in vertical direction while this option is selected. Reset this Mode Reset mode specific settings (Clock , Phase and Position) to the factory-made defaults.
KVM over IP Module Figure 4-9 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. In this case you have to change the Local Keyboard setting to the right language, manually.
KVM over IP Module depth. They are only available unless "Transmission Encoding" is determined automatically (see the Section called Transmission Encoding in Chapter 6). Compression Level You may select a value between 1 and 9 for the desired compression level with level 1 enabling the fastest compression and level 9 the best compression.
KVM over IP Module Figure 4-12 Predefined Compression 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 Figure 4-14 Encoding Color depth 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.

KVM over IP Module 5.2 Virtual Media The IP-KVM provides a powerful capability called Virtual Media (or Virtual Disk). Using the USB port, the IP-KVM can present either a local floppy disk image or a redirected remote CD/DVD-ROM image to the target computer. This can allow system recovery in conditions as bad as having local disks down and no primary network connection. With Floppy Disk Image, the user can upload an image to the IP-KVM’s memory, which then emulates a locally attached floppy drive.
KVM over IP Module 5.2.1 Drive Redirection The Drive Redirection is another possibility to use a virtual disc drive on the remote computer. With Drive Redirection you do not have to use an image file but may work with a drive from your local computer on the remote machine. The drive is hereby shared over a TCP network connection. Devices such as floppy drives, hard discs, CD-ROMs and other removable devices like USB sticks can be redirected.
KVM over IP Module Please note that Drive Redirection works on a level which is far below the operating system. That means that neither the local nor the remote operating system is aware that the drive is currently redirected, actually. This may lead to inconsistent data as soon as one of the operating systems (either from the local machine, or from the remote host) is writing data on the device.
