4.1.3.2 Remote Mouse Settings

A common problem with KVM devices is the synchronization between the local and remote mouse cursors. The KVM-0850/1650 addresses this situation with an intelligent synchronization algorithm. There are two mouse modes available on the KVM-0850/1650.

Auto mouse speed

The automatic mouse speed mode tries to detect the speed and acceleration settings of the host system automatically. See the section below for a more detailed explanation.

Fixed mouse speed

This mode just translates the mouse movements from the Remote Console in a way that one pixel move will lead to n pixel moves on the remote system. This parameter n is adjustable with the scaling. It should be noted that this works only when mouse acceleration is turned off on the remote system.

4.1.3.3 Auto mouse speed and mouse synchronization

The automatic mouse speed mode performs the speed detection during mouse synchronization. Whenever the mouse does not move correctly, there are two ways for re-synchronizing local and remote mouse:

Fast Sync

The fast synchronization is used to correct a temporary, but fixed skew. Choose the

option using the Remote Console options menu or press the mouse synchronization hotkey sequence in case you defined one.

Intelligent Sync

If the fast sync does not work or the mouse settings have been changed on the host

system, use the intelligent resynchronization. This method takes more time than the fast one and can be accessed with the appropriate item in the Remote Console option menu. The intelligent synchronization requires a correctly adjusted picture. Use the auto adjustment function or the manual correction in the Video Settings panel to setup the picture. The Sync mouse button on top of the Remote Console can behave differently, depending on the current state of mouse synchronization. Usually pressing this button leads to a fast sync, except in situations where the KVM port or the video mode changed recently.

Note: At first start, if the local mouse pointer is not synchronized with

the remote mouse pointer, press the Auto Adjust Button once.

4.1.3.4 Host system mouse settings

The host's operating system knows various settings from the mouse driver.

Warning

The following limitations are not for the Mouse Type of “MS Windows 2000 and newer”.

While the IP-KVM switch works with accelerated mice and is able to synchronize the local with the remote mouse pointer, there are the following limitations, which may prevent this synchronization from working properly:

Special Mouse Driver

There are mouse drivers which influence the synchronization process and lead to

desynchronized mouse pointers. If this happens, make sure you do not use a special vendor-specific mouse driver on your host system.

Windows XP Mouse Settings

Windows XP knows a setting named “improve mouse acceleration”, which has to be

deactivated.

Active Desktop

If the Active Desktop feature of Microsoft Windows is enabled do not use a plain

background. Instead, use some kind of wallpaper. As an alternative, you could also disable the Active Desktop completely.

Navigate your mouse pointer into the upper left corner of the applet screen and move it slightly forth and back. Thus the mouse will be resynchronized. If re-synchronizing fails, disable the mouse acceleration and repeat the procedure.

4.1.3.5 Single and Double Mouse Mode

The information above applies to the Double Mouse Mode, where remote and local mouse pointers are visible and need to by synchronize. The KVM-0850/1650 also features another mode, the Single Mouse Mode, where only the remote mouse pointer is visible. Activate this mode in the open Remote Console and click into the window area. The local mouse pointer will be hidden and the remote one can be controlled directly. To leave this mode, it is necessary to define a mouse hotkey in the Remote Console Settings Panel. Press this key to free the captured local mouse pointer.

4.1.3.6 Recommended Mouse Settings

For the different operating systems we can give the following advice:

MS Windows 2000/2003 (Professional and Server), XP In general, we recommend the usage of a mouse via USB. Choose USB without Mouse Sync. For a PS/2 mouse choose Auto Mouse Speed. For XP disable the option enhance pointer precision in the Control Panel.

SUN Solaris Adjust the mouse settings either via xset m 1 or use the CDE Control Panel to set the mouse to 1:1, no acceleration. As an alternative you may also use the Single Mouse Mode.

KVM-0850/1650 IP KVM switch

MAC OS X We recommend using the Single Mouse Mode.

4.1.3.7 Video Modes

The KVM-0850/1650 recognizes a limited number of common video modes. When running X11 on the host system, please do not use any custom mode lines with special video modes. If you do, the KVM-0850/1650 may not be able to detect them. We recommend using any of the standard VESA video modes, instead

5. Usage

5.1 Prerequisites

The KVM-0850/1650 features an embedded operating system and applications offering a variety of operating interfaces. This chapter will describe both these interfaces, and the way to use them in a more detailed manner. The interfaces are accessed using the TCP/IP protocol family, thus they can be accessed using the built-in Ethernet adapter.

The following interfaces are supported:

HTTP/HTTPS

You can full access the device via the embedded web server. The KVM-0850/1650

environment can be entirely managed using a standard web browser. You can access the KVM-0850/1650 using the insecure HTTP protocol, or using the encrypted HTTPS protocol. Whenever possible, use HTTPS.

Telnet

A standard Telnet client can be used to access an arbitrary device connected to the

KVM-0850/1650's serial port via a terminal mode.

The primary interface of the KVM-0850/1650 is the HTTP interface. This is covered extensively in this chapter. Other interfaces are addressed in subtopics.

In order to use the Remote Console window of your managed host system, the browser has to come with a Java Runtime Environment version 1.1 or higher. If the browser has no Java support (such as on a small handheld device), you are still able to maintain your remote host system using the administration forms displayed by the browser itself.

Important: We recommend installing a Sun JVM 1.4 or higher.

In order to access the remote host system using a securely encrypted connection, you need a browser that supports the HTTPS protocol, such as IE 6.0. Strong security is only assured by using a key length of 128 Bit. Some of the old browsers do not have a strong 128 Bit encryption algorithm.

Using the Internet Explorer, open the menu entry “? ” and “Info” to read about the key length that is currently activated. The dialog box contains a link that leads you to information on how to upgrade your browser to a state of the art encryption scheme. Figure 5-1 shows the dialog box presented by the Internet Explorer 6.0.

Newer web browsers do support strong encryption on default.

5.2 Using PS/2 KVM over IP switch as a KVM switch

The power on state of 8/16-port PS/2 KVM over IP switch: When you power on KVM switch, it will ask you the password, the default password value is eight zero –“ 00000000 “. Please key in eight zero and enter the same value at retype field. Note: Before you are not familiar with the operation of OSD manual, please don’t change the

password – i.e. keep default eight zero (00000000) value. Otherwise, if you have set the password and unfortunately forget the password, you need send it back to your distributor for

maintaining the password.

Please use the attached 3 feet 3-in-one daisy chain Cable Kit to daisy chain the KVM Switch.

A. Connect Keyboard, Mouse and Monitor to the console port (white color block) of bank 1 KVM

switch.

B. Use one end of 3-in-one Cable Kit to connect the daisy chain port of bank 1 and the other end

for the console port (white color block) of bank 2 KVM switch.

C. Please repeat item B to daisy chain more bank as you want. But, the maximum daisy chain

bank is eight levels.

D. Before chaining the slave bank up to six banks, you need a VGA extender between the fifth

bank and the sixth bank to enhance the VGA signal.

(Note: If you would like to daisy chain 8 port and 16 port KVM Switch together, the master bank must be 16 port KVM Switch)

5.2.2 Hot Plug

The KVM Switch supports “Hot Plug“ function for easy addition or removal of PCs. The user can arrange or maintain PCs as follows:

a. A PC can be disconnected and reconnected to the same or different port of the KVM unit

without having to power it off as long as it is not the Daisy-chain port or pass through port.

b. When the pass through port PC (i.e. The pass through port means the PC port that is

connected to console port directly) is powered on, for hot plug function, please switch this pass through port to next port (or say emulation port ) and then switch back to the pass through port.

c. You may unplug or plug the mouse or the keyboard from the console port any time.

OTE

Some O.S. (Operation Systems) like SCO Unix are unable to support “ Hot Plug ” function. If you apply “Hot Plug” to this kind of O.S., it will cause unpredictable behavior or shut down the PC. Before attempting to use “Hot Plug”, please make sure your O.S. and mouse software driver supports the “Hot Plug” function.
