Relative Mouse Mode KM Switching
When 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

System operation
There are four ways to control the SKM-04-PRO: 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:
# | STATUS | DESCRIPTION |
---|---|---|
1 | OFF | Non-selected port |
2 | ON | Selected port |
Hotkey Commands
A Hotkey command is a keyboard sequence used to trigger an action on the
SKM-04-PRO via the keyboard connected to the USB port of the SKM-04-PRO. 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.
COMMANDS | HOTKEY |
---|---|
Display Topology (multiple rows) | [CTRL][CTRL] H [1-4] |
Limit Input Ports (one row only) | [CTRL][CTRL] W [1-4] |
Cursor Rolling (roll past display borders up, down, left, and right) |
[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-PRO 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-PRO via Serial, you will see the SKM-04-PRO information when the device starts up.
The following commands can be used for RS-232 with available keyboard hotkeys:
COMMAND DESCRIPTION | HOTKEY | RS-232 COMMAND |
---|---|---|

Graphical User Interfaces
In addition to the front panel buttons, keyboard hotkeys, and RS-232 serial
commands described above, the SKM-04-PRO can be configured through a simple
GUI that offers all the same customization options as the other control
methods. This interface can be accessed on the connected computers.
Display Topology Configuration
The SKM-04-PRO has a configurable display topology configuration that can be
easily activated through keyboard hotkeys. No software or drivers are required
to configure the display topology.
Note: Hotkey CTRL + CTRL command allows for multiple rows.
Limit Input Ports Configuration
- The SKM-04-PRO 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):
Note: Limit Input Ports commands reset Display Topology configuration.
Resolution and Mouse Configuration
COMMAND DESCRIPTION | RS-232 COMMAND |
---|---|
Switch resolution | // ce [SPACE] [SKM #] [SPACE] [resolution #] [ENTER] |
Mouse control | // mm [SPACE] [resolution #] [SPACE] [x #] [y #] [ENTER] |
Mouse default position | // rl [ENTER] |
//CE [SPACE] [SKM #] [SPACE] [resolution #]
Where SKM channel can be set 1-4 Where Resolution number is the following:
- 1080p
- 4K
- 2K
- 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.
