Initial Setup
After all devices are connected to the SKM-04-PLUS, the user must choose a display topology configuration and display mode. By default, the SKM-04-PLUS is configured to a topology with four screens arranged horizontally starting with Port 1 on the left. The installation setup must match one of SKM-04-PLUS’s predefined display topology configurations. This can be selected through keyboard hotkey commands. Please refer to the Display Topology Configuration section for the available display topologies. Other configurations are possible through the GUI after initial setup.

Absolute Mouse Mode KM Switching
SmartAVI’s new PASS (Progressive Automatic Screen Switching) technology allows seamless switching between computers by moving the mouse cursor from one display to another. With PASS, users can effortlessly switch computers for faster productivity. PASS only works in Absolute Mouse Mode.

Auto-Switch Example:

• AUTO-SWITCH FROM 1 TO 2
  • SOURCE 1
  • SOURCE 2
• AUTO-SWITCH FROM 3 TO 1
  • SOURCE 3
  • SOURCE 4
• AUTO-SWITCH FROM 2 TO 4
  • CURSOR
  • CURSOR
• AUTO-SWITCH FROM 4 TO 3

Relative Mouse Mode KM Switching
For using computers with multiple displays, SmartAVI developed a new feature called Mouse Gesture Switching, which is a technology that allows switching between computers using simple mouse clicks and gestures. No device driver is required. Simply press the scroll wheel twice and then move the mouse in the direction of the channel you desire to switch to. This feature only works in Relative Mouse Mode.

Example:

• TO THE UPPER SCREEN
• SCROLL 2X THEN
• TO THE LEFT SCREEN
• TO THE RIGHT SCREEN
• TO THE LOWER SCREEN

System operation

There are four ways to control the SKM-04-PLUS: front panel buttons, keyboard hotkeys, RS-232 serial commands, and through the included graphical user interface (GUI).

Front Panel Control
To switch to an input port, simply push the button on the front-panel of the KM. If an input port is selected, the LED of that port will turn on.

Front Panel – Port Selection LEDs:

Hotkey Commands
A Hotkey command is a keyboard sequence used to trigger an action on the SKM-04-PLUS via the keyboard connected to the USB port of the SKM-04-PLUS. To activate the hotkey sequence, press the CTRL key twice and then enter the desired hotkey commands.
Note: All commands can use upper and/or lower case characters.

[CTRL][CTRL] O [0(OFF), 1(ON)]

Note: Display Topology specifies the number of horizontal columns. The number of vertical rows is calculated in the software by 4/n columns.

• Custom Hotkey Triggers
  Users can customize the keys that trigger hotkeys. The default trigger for hotkey function on the keyboard is Ctrl + Ctrl.

• The trigger function can be used to change to the following keys:
  Ctrl (Left / Right), Alt, Shift (Left / Right), Caps Lock, Scroll Lock, F1-F12

• To view the current hotkey trigger setting:
  Use the RS-232 command: / + / + ? + ? + Enter to view the current hotkey trigger. To reset the Hotkey Trigger, use the “Factory Defaults” command.

• To change the hotkey trigger setting:
  [hotkey] + [hotkey] + X + [desired hotkey] Example: If the user’s current hotkey trigger is Shift and they want to change it to Scroll Lock, the user would type Shift + Shift + X + Scroll Lock.

RS-232 Serial Control
The SKM-04-PLUS may also be controlled via RS-232 commands. To use these commands, you must use HyperTerminal or an alternate terminal application. The settings for the connection are as follows: Baudrate 115200; Data Bits 8; Parity None; Stop Bits 1; Flow Control None. Once you have connected to the SKM-04-PLUS via Serial, you will see the SKM-04-PLUS information when the device starts up.

The following commands can be used for RS-232 with available keyboard hotkeys:

[ENTER]
Disable/Limit Ports| [CTRL][CTRL] d [2-4] [ENTER]| // d [2-4] [ENTER]
Reset Software| [CTRL][CTRL] r [ENTER]| // r [ENTER]
Factory Defaults| [CTRL][CTRL] f [ENTER]| // f [ENTER]
Get Port Status| N/A| // ?? [ENTER]
Switch resolution Channel: 1-4 Resolution: 1 (1080p), 2 (4K), 3 (2K), 4 (720p)| N/A| // ce [SPACE] [SKM #] [SPACE] [RESOLUTION #]
Mouse control speed (per resolution type) X and Y axes set in percent [0-500]|

N/A

| // mm [SPACE] [resolution #] [SPACE] [x #] [y #]
Get resolution/mouse info| N/A| // rl [ENTER]

Graphical User Interfaces
In addition to the front panel buttons, keyboard hotkeys, and RS-232 serial commands described above, the SKM-04-PLUS can be configured through simple GUIs that offer all the same customization options as the other control methods. These interfaces can be accessed on the connected computers, in a web browser, or in an Android app.

Display Topology Configuration
The SKM-04-PLUS has a configurable display topology that can be easily activated through keyboard hotkeys. No software or drivers are required to configure the display topology.

1. Hotkey Command : “CTRL + CTRL + H + 4 + ENTER”
2. Hotkey Command: “CTRL + CTRL + H + 2 + ENTER”
3. Hotkey Command: “CTRL + CTRL + H + 3 + ENTER”
4. Hotkey Command : “CTRL + CTRL + H + 1 + ENTER”

With GUI

To reconfigure the display topology on the GUI,

1. Click the Topology and Display button in the left pane. If the display has not been previously configured, the default configuration will appear. The channels are color coded: yellow for Channel 1, green for Channel 2, blue for Channel 3, and red for Channel 4. The interface is click-and-drag.
2. Move the tiles for the four channels into the desired positions on the grid.
3. Click submit.

The GUI will display a dialog box to confirm that the topology has been updated.

Limit Input Ports Configuration
The SKM-04-PLUS allows the user to shut off input from specific connected computers without the need to disconnect them from the switch.
Note: Limit Input Ports commands reset the Display Topology configuration.

Hotkey Commands: CTRL, CTRL W (X) commands (allows one row only):

• CTRL + CTRL + W + 4 + ENTER
• CTRL + CTRL + W + 3 + ENTER Note: Port 4 N/A
• CTRL + CTRL + W + 2 + ENTER
• CTRL + CTRL + W + 1 + ENTER
  • Note: Port 2-4 N/A
  • Note: Limit Input Ports commands reset Display Topology configuration.

With GUI

1. Click the Configuration button in the left pane.
2. Under USB Settings, use the Limit Ports dropdown menu to turn on or off the input from desired ports.
3. Click Apply.

Resolution and mouse configuration only work in absolute mouse mode (//KS)

[SPACE] [x #] [SPACE] [y #] [ENTER]
Get resolution/mouse info| // rl [ENTER]

//CE [SPACE] [SKM #] [SPACE] [resolution #] Where SKM channel can be set 1-4

Where Resolution number is the following:

1. 1080p
2. 4K
3. 2K
4. 720p

For example: //CE 1 2

• In this example we are setting channel 1 to reference 4K resolution. //MM [SPACE] [resolution #] [SPACE] [x integer # (1-100)] [y integer # (1-100)]

For example: //MM 2 80 50
In this example we are setting the mouse movement according to 4K resolution with 80 as the mouse speed mulitplier for X and 50 as the mouse speed multiplier for Y. The integer number set for the mouse multiplier will act as a value from 1-100%.

In the example above we are using the following:

• 80 for X, therefore 80 will become 80% of the mouse movement moving horizontally on the X-axis 50 for Y, therefore 50 will become 50% of the mouse movement moving vertically on the Y-axis
• 100 will do 100%, 65 will do 65%, 5 will do 5%, etc. Suppose you move the mouse 100 units for the X axis and 10 units for the Y axis. The software will change 100 80% = 80 units for the X axis and 10 50% = 5 unit for the Y axis. This will cause the mouse cursor to move slower.
• //RL will return the channel’s current mouse mulitplier percentage and the current resolution which will reference the resolution number mentioned in the //CE command.

With GUI

1. Click the Mouse Speed Settings button in the left pane. Each channel is represented by a dropdown menu at the bottom of the center pane.
2. Follow the formula outlined in the previous section to calculate the desired mouse settings for each channel.
3. Click the X or Y axis for the desired channel and enter the mouse multiplier.
4. Click Submit.

Settings Files

In addition to one-time adjustment of settings through any of the control methods, the user can establish a settings file through the GUI. This allows the user to restore a previous configuration with a single click instead of making each adjustment every time they log in.

Creating a Settings File

1. Open the KM Configuration Tool.
2. Adjust the display configuration to your preferred settings.
3. Click “Create Settings File.
4. This will open a standard dialogue box for saving a .txt file. Navigate to the desired folder and click Save.

Loading a Settings File

1. Open the KM Configuration Tool.
2. Click “Load Settings File.”
3. Select the desired settings file and click Open.
