The »DVIMUX4-DL-PS/2« KVM switch The »DVIMUX4-DL-PS/2« KVM switch The DVIMUX4-DL-PS/2 KVM switch enables you to operate up to four computers via one console. The console has to be supplied with a PS/2 keyboard, a PS/2 mouse and a digital and/or analog monitor. The computers connected to the KVM switch are operated at the installed console.
Installation Installation Overview of the interfaces Front panel of the KVM switch The front panel of the KVM switch provides two USB interfaces to connect a USB keyboard and/or mouse. NOTE: The PS/2 interfaces to connect the console keyboard and mouse (at the back panel of the KVM switch) and the USB interfaces at the front panel of the device can be used at the same time.
Installation Connecting the console devices NOTE: Connect the cables of the console and the computers preferably block by block and from the bottom up. By doing so, you will avoid already connected cables blocking your view of the interfaces. Monitor 1 DVI-I CPU 1.1 DVI-I CPU 2.1 DVI-I CPU 3.1...
Installation Connecting the computers IMPORTANT: KVM cable sets are required to connect the computers to the KVM switch. A list of the available KVM cable sets can be found on page 30. Assign the KVM cable sets to the different computers and place them ready for installation.

Further information Further information Support of digital and analog video signals Computers that provide digital or analog video signals can be connected to the KVM switches of the DVIMUX4-DL series. The signal type (digital or analog) that is transmit- ted from computer to KVM switch is displayed unaltered on the connected monitor. Uniform signal type within one video channel Install a console monitor that can display the uniform signal type of the computer’s video channels (only digital or analog).
Initiation Initiation Turn on the Power switch on the back panel of the KVM switch. As soon as the device is supplied with power, the green User LED lights up. The KVM switch is now ready for operation. Status displays The LEDs on the front panel of the device enable you to control the operational status at all time.
Switching between the computers Switching between the computers The user can either use the four buttons on the front panel of the device or key com- binations to switch between different computers. Keyboard and mouse inputs are forwarded to the active computer. The video signal of the active computer is displayed at the console monitor.

Switching between the computers Switching commands The following commands are provided for switching the channel: Command Channel <! switch to previous channel >! switch to next channel ADVICE: Use the » « command to show the currently accessing channel. NOTE: The serial device carries out the command directly after it has been sent.
Configuration Configuration The configuration of the KVM switch can optionally be changed in the setup mode or in the setup menu: Enable the setup mode using the console keyboard. You can change the configura- tion via special setup keys. ...
Configuration Operating the setup mode The setup mode can be enabled using the console keyboard. After enabling, the con- figuration of the KVM switch can be changed by using various step keys. NOTE: Only one setup function can be performed after the calling of the setup mode. If you want to perform more functions, please restart the setup mode.
Configuration Operating the setup menu The setup menu provides a convenient alternative to view and edit the configuration of the KVM switch. The switch can be operated through the setup menu which both easy operation and adjustment of several settings within a session. The setup menu can be operated via any terminal emulator (e.g.

Configuration Configuration settings Using single or double hotkeys If many application programs with key combinations are operated on one computer or if different G&D devices are used in one cascade, the number of available key combinations might be restricted. In such a case, it is appropriate to apply double hotkeys. How to enable single or double hotkeys: 1.
Configuration Changing the single hotkey Press the hotkey and the Backspace key simultaneously to start the setup mode of the KVM switch. Pressing the hotkey and the select key simultaneously enables the switching of channels. If an application program or another G&D device uses the same hotkey within the cascade, the hotkey can be changed.
Configuration Changing the double hotkey If the use of double hotkeys is enabled (see page 16), press the double hotkey and the Backspace key simultaneously to start the setup mode of the KVM switch. Switching of channels takes place by pressing the double hotkey and a select key at the same time.
Configuration Changing the select keys In the default settings, use the enabled select keys to switch between the com- puters that are connected to the KVM switch. For instance, you can switch to computer 2 by pressing Hotkey+2 (default: Ctrl+2 How to choose a different select key set: 1.
Configuration Disabling/Enabling the hotkey delay Press the Hotkey+Backspace (default: Ctrl+Backspace ) key combination for seven sec- onds in order to start the setup mode in the default settings. You can disable the hotkey delay if you want to start the setup mode immediately after pressing the key combination.
Configuration Resetting the default settings This function resets the default settings of the KVM switch. IMPORTANT: Performing this function reactivates the default settings of the KVM switch as shown on page 12! How to reset the default settings: Hotkey+Backspace Ctrl+Backspace 1.
Configuration Auto-accessing the first channel Usually, after turning on the device, the recently active channel is accessed. The set- ting can be changed so that the computer connected to the first channel is automati- cally accessed when the device is turned on. How to disable/enable the automatic access of the first channel after booting: NOTE: The option to automatically access the first channel after booting the device...
Configuration (De)activating the switching via hotkeys In the defaults, you can use hotkeys to switch between the computers. If desired, you can deactivate this kind of switching in the setup menu. How to enable/disable the switching via hotkeys: NOTE: Use the setup menu to (de)activate the switching via hotkeys. 1.
Configuration (De)activating the switching via step keys Instead of using hotkeys to switch to one of the channels connected to the KVM switch, you can also use step keys to switch the channels in ascending or descending order. NOTE: The use of step keys is disabled in the default settings. After enabling the step keys, you can use the following key combinations to switch channels in ascending or descending order: ...
Configuration Changing the bit rate of the Service port The Service port of the KVM switch can be used both for operating the setup menu and for switching the channels with a serial device. The Service port transfers a certain amount of data per time unit. The bitrate is given in bit/s.
Configuration Changing the standard mode of the Service port The Service port of the KVM switch can be used both for operating the setup menu and for switching the channels with a serial device. IMPORTANT: Depending on the purpose of use, the KVM extender distinguishes between the modes listed below.
Configuration Changing the scan code set of a PS/2 keyboard If a key is pressed on the PS/2 keyboard, the keyboard processor sends a data packet that is called scan code. The two common scan code sets (sets 2 and 3) contain dif- ferent scan codes.
Configuration Selecting the PS/2 keyboard type In addition to standard PS/2 keyboards, the KVM switch also supportsPixelPower Clar- ity (blue) and SKIDATA1 keyboards. Select the keyboard type if you want to use such a keyboard at the console. NOTE: The PS/2 keyboard type can only be selected in the setup menu. How to select the PS/2 keyboard type: 1.
Configuration Enabling or resetting a PS/2 mouse Compared to USB mouses, PS/2 mouses do not support hot plug technology. You can therefore insert the PS/2 plug during operation, but it may be possible that the computer does not detect the input device. To enable or reset the PS/2 mouse, the KVM switch can be used to send a special command to the computer.
