|
| This section explains the normal functions of the KVM Combiner offered to the user. |
| Normal Mode |
|
The KVM Combiner enable simultaneous interaction with 4 different hosts (PCs) using single display keyboard and mouse. When the user interacts with application at a specific window that channel is active and the mouse and keyboard affecting only that channel.
The user may move to a different channel by switching first to system mode. While in system mode the cursor will change to the selected system mode cursor and will enable free movement throughout the display area. |
When the KVM Combiner is in Normal Mode:
- Mouse cursor is controlled by the system mouse.
- Mouse cursor is generated / controlled by the host OS / Application.
- Mouse movement is limited to the active window area.
- All mouse keys (and wheel) will function based on the host specific application.
- Keyboard connected to the active window host.
- Audio output of active channel will be heard at 100% volume, other channels will be attenuated to 25% or muted.
- Active window will always be on top of all other windows.
- Title bar / task bar not shown, keys are not accessible.
- Pressing + / - keys will change to System Mode.
|
| System Mode |
|
The system mode enables the user to manage his/her combined desktop and customize it for the job being done. This mode also enables the user to move between windows and to maximize windows as needed. |
When the KVM Combiner is in System Mode:
- Mouse cursor is controlled by the system mouse
- Mouse cursor is generated / controlled by the KVM Combiner
- Mouse movement is unlimited in all display area
- Keyboard is routed to the active window (active window is always in front)
- Audio output is routed to the active window
- Title bar / task bar visible keys are accessible
- Pressing + / - keys will change to Normal Mode and the active window will be the window where the system cursor was last positioned.
- Left clicking on a window will bring it to the front and make it active window.
- Pressing left mouse key and holding – will drag the window under it.
- Double clicking on a window will maximize that window.
|
| Toggling between Normal and System modes |
|
The mouse +/- side keys triggers cyclic toggling between modes. System mode can be easily identified by the appearance of the task bar at the bottom of the display. |
| Switch between windows |
|
To move between windows, the user should switch to system mode by pressing the mouse + or – side keys and the using system cursor to touch another window. Changing back to normal mode will make the new window an active window.
Another option to switch between windows in system mode is by using the wheel in the mouse. Windows will move to the front at a cyclic sequence. |
| Cascade / Tiles Modes |
|
Pressing the "Tile" key located at the task bar arranges all 4 windows on the display (see Pict on the Right). Pressing the "Cascade" key located at the task bar arranges all 4 windows one on top of the other (see Pict on the Left).
|
| Moving a Window |
Window resizing |
In order to move a window user should first switch to system mode by pressing + or – mouse side keys. In system mode, hold the left mouse key when the system cursor located on the desired window and the window will move. Release left mouse key to drop window in place. Window movement on the left side is limited by the display boundary. Window movement on the right side is unlimited (window may be pushed out of the display area). |
In order to resize a window user should first switch to system mode by pressing + or – mouse side keys. In system mode, hold the right mouse key when the system cursor located on the desired window and the window will start resizing moving the lower right window corner. Release right mouse key to freeze window size. |
When window size is smaller than input image size, scroll bars will be shown in border. To move internal image inside smaller window, enter system mode and click on both left and right mouse keys together. Then internal image can be dragged inside window.
Note: Currently this feature is supported only by PS/2 mouse.
|
| Help key |
|
The ? key located at the task bar show mouse functionality bitmap.
|
| Preset keys |
|
Preset keys located at the task bar marked as 1, 2, and 3 (see figure 20) enable window arrangement saving and loading. Preset keys are useful to store user specific settings for specific job environments.
To save a setting the user should enter system mode and then click on one of three preset keys. As the save process starts the key will show a small progress bar. After loading, clicking the preset key will load preset KVM configuration.
|
| Maximizing a window |
|
To maximize a window to its full size – enter System Mode by pressing + or – mouse side keys then bring the system cursor to the window that should be maximized and then double click on that window. The selected window will maximize to its native input resolution. If that resolution is identical to output resolution – window frame would not be shown. To leave maximize mode – change back to system mode and re arrange windows as needed.
Note: When the K400 KVM Combiner maximizes a window it will change output display resolution to the input resolution. The reaction of this change on the display may change according to the display design. Some display may automatically adjust to new resolution and rescale (showing full image), while other may not and will show black borders around image. |
| Deactivating / Activating channels |
|
The user can remove from the KVM Combiner display inactive channels. In order to deactivate a channel the user should enter system mode and then move the system cursor to the desired channel key at the task bar and double-click on it. Red X should appear on that channel.
In some cases the user may want to deactivate a live channel for operational reasons. The K400 will display instead on that channel a background color.
Repeating this process will cancel this status and reactivate that channel. Once a channel had been deactivated it would not participate in cyclic toggling between windows. |
| Failsafe mode |
|
This mode is available only in airborne derivative of the K400.
If power is lost to the K400 KVM Combiner or device detected internal failure, Channel 1 will be selected and maximized. |
| Mouse Functions |
|
The K400 KVM Combiner uses 5 keys mouse to control host applications as well as system control applications (managing the KVM Combiner). The use of 5 keys mouse enables the user to fully use all standard wheel mouse keys for application specific tasks and still operate KVM Combiner specific functions using the 2 extra side keys. |
