9 9.1 Configuration Network configuration using PSetup utility After the initial setup, the CAT5 8-PORT/16-PORT IP-KVM can be managed via the Internet using a standard browser that lets you control the device/s attached to it. However, to configure the CAT5 8-PORT/16-PORT IP-KVM’s network access, the user must first run the PSetup Utility software that is included on the CD-ROM included in your package.
3) Use the PSetup Utility to search for the CAT5 8-PORT/16-PORT IP-KVM on your network: a) Click the Refresh Devices button to show the MAC addresses of all connected devices on your network. b) Find the MAC address of the CAT5 8-PORT/16-PORT IP-KVM by clicking on the “Device MAC Address” drop-down box. Select your device’s MAC address from the dropdown list. c) After selecting your CAT5 8-PORT/16-PORT IP-KVM’s MAC address, click Query Device to view the device’s Network Configuration in the top right area.
OK Enabling DHCP to get a dynamic IP address: If you have installed the CAT5 8-PORT/16-PORT IP-KVM on the subnet (intranet) of a DHCP server, or the subnet of a router that supports DHCP, you can use the PSetup Utility to find the dynamic IP address of the CAT5 8-PORT/16-PORT IP-KVM. DHCP automatically assigns a dynamic IP address to the CAT5 8-PORT/16-PORT IP-KVM.
6) Use the PSetup Utility to search for the CAT5 8-PORT/16-PORT IP-KVM on the network (see the image below): a) Click the Refresh Devices button to detect all connected devices. b) Find the MAC address of the CAT5 8-PORT/16-PORT IP-KVM by clicking on the “Device MAC Address” drop-down box.

This option is only available if IP auto-configuration is disabled. Gateway address Enter the IP address of the default router for the connected IP subnet. If you do not have a default router, enter 0.0.0.0. This option is only available if IP auto-configuration is disabled. 9.
Fixed mouse speed This mode just translates the mouse movements from the Remote Console so that one pixel of movement will result in “n” number of pixel moves on the Host system. The value of “n” is adjustable. Please note that this works only when mouse acceleration settings are turned off on the Host computer. 9.3.3 Automatic mouse speed and mouse synchronization The automatic mouse speed mode performs the speed detection during mouse synchronization.
mode, the mouse pointers may need to be synchronized in order to ensure they are pointing at the same position on your Host computer screen. You can define a hotkey to quickly sync the two mouse pointers. Single Mouse Mode: In this mode, only one mouse pointer is visible – the Remote computer pointer. On the Remote computer, when you click on the Remote Console window, your mouse pointer will be “captured”, and all mouse movement will be inside the Remote Console window only.
Mac OS X Settings Mac OS X (on Host computer): If the host computer is running on any version of Mac OS X, we recommend using Single Mouse mode. SUN Solaris Settings SUN Solaris (on Host computer): If the host system is running SUN Solaris, adjust the mouse settings of the system by entering “xset m 1” into the console, or use the CDE Control Panel to set the mouse to “1:1, no acceleration”. Alternatively, you could use the Single Mouse mode only.
10 10.1 Usage Prerequisites The CAT5 8-PORT/16-PORT IP-KVM features an embedded operating system and applications that support two standardized interfaces – HTTP/HTTPS and Telnet. This chapter will describe both these interfaces in detail, as well as how to use them. Both interfaces are accessed using the TCP/IP protocol family. ■ HTTP/HTTPS Full access is provided by the embedded web server. The CAT5 8-PORT/16-PORT IP-KVM environment can be entirely managed by using a standard web browser.
browsers do not have a strong 128-bit encryption algorithm. If you are using Internet Explorer, click on the top toolbar menu option marked “?”, then click on “About Internet Explorer” to see the current “Cipher Strength” (the passkey length that is currently activated). The dialog box contains a link that leads you to information on how to upgrade your browser to a more powerful encryption scheme. The screenshots below shows the dialog boxes presented by IE 8 and IE 6.
10.2 Log in/out CAT5 8-PORT/16-PORT IP-KVM 10.2.
WARNING: Please make sure that you change the default Super User password immediately after you have installed and accessed your CAT5 8-PORT/16-PORT IP-KVM for the first time. Leaving the password as it is represents a severe security risk and may result in unauthorized access to the CAT5 8-PORT/16-PORT IP-KVM as well as the entire Host system and connected devices! NOTE: Your web browser has to be set up to accept cookies, or else you won’t be able to log in.
Return to the main page of the IP-KVM’s web GUI Open the IP-KVM Remote Console Log out and exit from the IP-KVM’s web GUI. NOTE: If there is no user activity for 30 minutes, the CAT5 8-PORT/16-PORT IP-KVM will log you out automatically. Clicking on any of the menu items will bring you back to the login screen. Remote Console Preview Click on Click to open to start the remote console redirection Click on Refresh to refresh the picture. 10.2.
The Remote Console is the redirected screen, keyboard and mouse of the remote host system that CAT5 8-PORT/16-PORT IP-KVM controls. The Remote Console window is a Java Applet that tries to establish its own TCP connection to the CAT5 8-PORT/16-PORT IP-KVM. The protocol that is running over this connection is neither HTTP nor HTTPS, but RFB (Remote Frame Buffer Protocol). By default, RFB tries to establish a connection to TCP port 443. Your local network environment must allow this connection to be made, i.
Remote Console will behave exactly in the same way as if you were sitting in front of it. This means you can use your keyboard and mouse in the usual way. However, be aware of the fact that the feedback from keyboard and mouse actions on the Host system will be slightly delayed. The delay depends on the bandwidth of the between you and the CAT5 8-PORT/16-PORT IP-KVM. Differences between the Remote computer’s keyboard layout and the Host computer’s keyboard settings may lead to some problems.
Ctrl+Alt+Delete Click this button to send the “Control Alt Delete” key-sequence command to the remote system. (Also, see section 5.4.1 for configuring new key-sequence buttons). Drive Redirection button Click this button to open the Drive Redirection options at the top of the Remote Console window (see the screenshot below). For more details, see section 11.2.
Options Click on this button to open the “Options” menu. Figure 35: Remote Console Options Menu A short description of the options as follows. • Monitor Only Click this command to toggle the Monitor Only function on or off. If this function is switched on, the Remote-side user can only monitor the Host-side user’s console, and cannot control it.
This allows the Remote-side user to scale down the Remote Console window on their monitor. The mouse and keyboard controls will stay the same, but the scaling algorithm will not preserve all the display details. When you select 25%, 50%, or 100% scaling, the size of the Remote Console window is calculated according to the Host video settings and the scaling algorithm.
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. • Local Cursor This submenu offers a list of different cursor shapes for the mouse pointer visible by the Remote user. The selected shape will be saved for the current user and activated the next time this user opens the Remote Console.
Video Settings via the Remote Console’s “Options > Video Settings” Figure 39: Video Settings Panel Brightness - Controls the brightness of the picture Contrast Red/Green/Blue - Controls the contrast of the picture Clock - Defines the horizontal frequency for the video mode. Different video card types may require different values here. The default settings in conjunction with the auto adjustment procedure should be adequate for most configurations.
video display, but some small changes in the display may not be recognized immediately. A small filter setting displays all changes instantly, but may lead to a constant stream of network traffic, even if the display content is not actually changing (depending on the quality of the video input signal). In general, the default setting should be suitable for most situations. Click the “Force Composite Sync” button if you are using a SUN computer or server on the Host-side.
Figure 41: 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.
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. The most suitable compression level should always be seen as a compromise between the network bandwidth that is available, on your video picture to be transferred, and on the number of changes between two single video pictures. We recommend to use a higher compression level if the network bandwidth is low.
Figure 43: 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. This compresses well, but leads to degradation in image quality.
Figure 45: 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.
Figure 46: 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 CAT5 8-PORT/16-PORT IP-KVM will not have to do any video compression. In total, this will lead to less transfer time of the motion picture.
10.3.3 Status Line of Remote Console Status line The status bar shows the status of the Remote Console as well as the status of the connection between the Host system and the Remote system. The size of the remote screen is displayed. Figure below was taken from a Remote Console with a resolution of 1024x768 pixels. The value in brackets describes the connection to the Remote Console. “Norm” means a standard connection without encryption; “SSL” means a secure connection.
11 Menu Option 11.1 Remote Control The Remote Console is the redirected screen, keyboard and mouse of the remote host system that CAT5 8-PORT/16-PORT IP-KVM controls. The Remote Console window is a Java Applet that tries to establish its own TCP connection to the CAT5 8-PORT/16-PORT IP-KVM. Starting the Remote Console opens a new window displays screen movement of host system, with its size automatically adjusted to optimum. Keyboard and mouse are redirected to control the host system simultaneously.
11.1.1 KVM Console Figure 49: KVM Console To open the KVM console either click on the icon Console or Remote Control > KVM Console of the menu entry on the left or Click to open of the console picture on the right. 11.1.2 Telnet Console/SSH Console In general, the Telnet or SSH interface supports two operation modes: the command line mode and the terminal mode. The command line mode is used to control or display some parameters.
Telnet Console The CAT5 8-PORT/16-PORT IP-KVM firmware features a Telnet server that enables a user to connect via a standard Telnet client. In case the Telnet program is using a VT 100, VT 102 or VT 220 terminal or an according emulation, it is even possible to perform a console redirection as long as the CAT5 8-PORT/16-PORT IP-KVM host machine is using a text mode screen resolution. To log in Telnet Console by one of the following way: 1.
2. or telnet command as required by the Telnet client, for instance in a UNIX shell: telnet 192.168.0.70 3. or run the SSH-supported terminal emulation program (such as PuTTY). Replace the IP address by the one that is actually assigned to the CAT5 8-PORT/16-PORT IP-KVM. This will prompt for username and password in order to log into the device. The credentials that need to be entered for authentication are identical to those of the web interface.

11.1.3 Remote Wakeup The CAT5 8-PORT/16-PORT IP-KVM provides the remote power wakeup function, which can remotely wake up the sleeping computer. With this feature, the computers that are not in use for now can be shut down and remotely wake up the computer when want to use it, and thus save the power energy. Settings on target computer: To wake up a remotely located computer via the CAT5 8-PORT/16-PORT IP-KVM, some settings have to be pre-configured on the target computer: 1.
Make sure Wake on Magic packet is Enable.
Make sure the following two items are selected. Settings on CAT5 8-PORT/16-PORT IP-KVM: The control can be easily configured via web GUI. 1. Click on Remote Control > Remote Wakeup to bring up the configuration page. 2. Type in the computer/server description and the computer/server’s IP address. 3. Click on the Get MAC button to obtain and automatically add the corresponding MAC address of the selected computer. 4. Click on the Apply button to save the entry. 5.
11.2 Virtual Media The CAT5 8-PORT/16-PORT IP-KVM provides a powerful feature called Virtual Media (or Virtual Disk). The CAT5 8-PORT/16-PORT IP-KVM can present either a local floppy disk image (stored on the CAT5 8-PORT/16-PORT IP-KVM) or a redirected remote CD/DVD-ROM image (redirected from the Remote computer) to the target computer through the built-in USB port. This can allow for system recovery in conditions including disk failure or no primary network connection on the target computer.
11.2.1 Drive Redirection The Drive Redirection function gives the administrator another virtual disk drive on the Host computer. With Drive Redirection, you do not have to use an image file. Instead, the Remote-side user can open a drive on his or her local computer and use it on the Host machine. Thus, the drive is shared over a TCP network connection. Devices that can be redirected are floppy drives, hard disks, CD-ROM drives, and other removable devices such as USB storage drives.
Please be noted that Drive Redirection works on a more basic level than the operating systems of the computers. This means that neither the Remote-side nor the Host-side operating system is aware that the drive is being redirected. This may lead to inconsistent data when the operating system (either on the Remote-side or Host-side machine) is writing data on the device. If write support is enabled, the Host computer might damage the data and the file system on the redirected device.
system could possibly hang in boot mode due to changes in the boot order or the boot manager (LILO, GRUB). Such incidents were reported for some Windows versions (Windows 2000 and Windows XP), and other operating systems might behave in the same way. The actual OS behavior will depend on the BIOS version used in the specific machine.
11.2.3 CD/DVD Image Use Image on Windows Share (via SAMBA) To include an image from a Windows share, select “CD/DVD Image” from the submenu. Figure 53: Virtual Media - CD-ROM Image Share host Enter the server name or its IP address (the computer/server that shares out the image file). Note: For Windows 95, 98 and Windows ME, do not enter the IP address; enter the server name (e.g. “NetBIOS Name”). Share folder name Enter the name of the relevant share folder.
Notes: 1. The output image extension file must be an ISO image file, and the file name extension must be ‘iso’, e.g. CD-Rom_vir.iso. 2. You can create an ISO file up to 650 MB in size (CD-ROM size). This drive will be accessible only in read-only mode, you will not be able to write any information to it. This drive can act as a boot drive if the motherboard/BIOS on the Host computer supports the USB BOOTABLE function. For emulating a DVD Drive, please use Drive Redirection function. 3.
Operation Procedures: 1. Please run Nero or any CD/DVD imaging tool to create CD/DVD ISO image. 2. Please create a folder and share this folder on the PC that shares out the image file. Copy the CD/DVD ISO image file to this sharing folder. (Please make sure password has to be setup with the authorized user during Sharing => Permission settings) MS Windows Open the Explorer, navigate to the directory (or share) and press the right mouse button to open the context menu.

3. Fill in the sharing information on Image on Windows Share, and click the Set button to save the settings. 4. If the Image file set successfully, a screen like the one below will appear. 5. Open the remote console and you can see the virtual CD as shown below.
11.2.4 Floppy Disk Figure 56: Virtual Media - Floppy Disk The maximum image size is limited to 1.44MB. To use a larger image, mount this image via Windows Share (or SAMBA) (see the Section called Use Image on Windows Share (via SAMBA) for details) Operation Procedures: 1. You need to create the floppy image file first (Please refer to the section “Creating a floppy image”). For this example, we used Raw Write program (or any other image-creator software) to create the floppy image.
8-PORT/16-PORT IP-KVM module’s on-board memory 4. After you uploading the image file, you will see the information below. 5. Open the remote console and you will see a virtual Floppy drive is created on the host computer that connected to CAT5 8-PORT/16-PORT IP-KVM. The maximum size of the floppy image disk is 1.44MB. This drive is in read-only mode and does not allow you to write any information on the drive.
11.2.5 Creating an Image 11.2.5.1. Creating a Floppy Image MS Windows You can use the tool “Raw Write for Windows”. You can get the RawWrite software from the website http://www.chrysocome.net/rawwrite. Figure 57: Raw Write for Windows selection dialog From the menu, select the tab “Read”. Enter (or choose) the name of the file in which you would like to save the floppy content. Click on the button “Read” to initiate the image creation process.
11.2.5.2. Creating a CD/DVD ISO Image MS Windows To create the image file, use your favorite CD imaging tool. Copy the whole contents of the disk into one single image file on your hard disk. For example, with “Nero” you should select “Copy and Backup”. Then, click on the “Copy Disc” section. Select the CD-ROM or DVD drive you would like to create an image from. Specify the filename of the image, and save the CD-ROM content in that file.
