INITIAL SETUP

Absolute Mouse Mode KM Switching

Relative Mouse Mode KM Switching

Aer all devices are connected to the SKM-04-LT, the user must choose a display topology

conguraon and display mode. By default, the SKM-04-LT is congured to a topology with four

screens arranged horizontally starng with Port 1 on the le.

The installaon setup must match one of SKM-04-LT’s predened display topology conguraons.

This can be selected through keyboard hotkey commands. Please refer to the “Display Topology

Conguraon” secon for the available display topologies.

SmartAVI’s new PASS (Progressive Automac Screen Switching) technology allows seamless switching

between computers by moving the mouse cursor from one display to another. With PASS, users can

eortlessly switch computers for faster producvity. PASS only works in Absolute Mouse Mode.

When using computers with mulple 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 direcon of the channel you desire to switch to. This feature only works in

Relave Mouse Mode.

Note: Display Topology species the number of horizontal columns. The number of vercal rows is

calculated in the soware by 4/n columns.

Custom Hotkey Triggers

Users can customize the keys that trigger hotkeys. The default trigger for hotkey funcon on the

keyboard is Ctrl + Ctrl. The trigger funcon can be used to change to the following keys:

Ctrl (Le / Right), Alt, Shi (Le / Right), Caps Lock, Scroll Lock, F1-F12

To view the current hotkey trigger seng:

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 seng:

[hotkey] + [hotkey] + X+ [desired hotkey]

Example: If the user’s current hotkey trigger is Shi and they want to change it to Scroll Lock, the user

would type Shi + Shi + X+ Scroll Lock.

System operation

There are four ways to control the SKM-04-LT: front panel buons, 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 buon on the front-panel of the KM. If an input port is

selected, the LED of that port will turn on.

Front Panel - Port Selecon LEDs:

Hotkey Commands

A Hotkey command is a keyboard sequence used to trigger an acon on the SKM-04-LT via the

keyboard connected to the USB port of the SKM-04-LT. To acvate 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.

System operation (continued)

RS-232 Serial Control

The SKM-04-LT may also be controlled via RS-232 commands. To use these commands, you must use

HyperTerminal or an alternate terminal applicaon. The sengs for the connecon are as follows:

Baudrate 115200; Data Bits 8; Parity None; Stop Bits 1; Flow Control None.

Once you have connected to the SKM-04-LT via Serial, you will see the SKM-04-LT informaon when

the device starts up.

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

Graphical User Interfaces

In addion to the front panel buons, keyboard hotkeys, and RS-232 serial commands described

above, the SKM-04-LT can be congured through a simple GUI that oers all the same customizaon

opons as the other control methods. This interface can be accessed on the connected computers.

Display Topology Conguraon

The SKM-04-LT has a congurable display topology conguraon that can be easily acvated through

keyboard hotkeys. No soware or drivers are required to congure the display topology.

Note: Hotkey CTRL +CTRL command allows for mulple rows.

(1) Hotkey Command: “CTRL +CTRL +H +4 +ENTER”

Limit Input Ports Conguraon

The SKM-04-LT allows the user to shut o input from specic connected computers without the need

to disconnect them from the switch.

Note: Limit Input Ports commands reset the Display Topology conguraon.

Resoluon and Mouse Conguraon

System operation (continued)

//CE [SPACE] [SKM #] [SPACE] [resoluon #]

Where SKM channel can be set 1-4

Where Resoluon number is the following:

1. 1080p

2. 4K

3. 2K

4. 720p

For example: //CE 1 2

In this example we are seng channel 1 to reference 4K resoluon.

//MM [SPACE] [resoluon #] [SPACE] [x integer # (1-100)] [y integer # (1-100)]

For example: //MM 2 80 50

In this example we are seng the mouse movement according to 4K resoluon with 80 as the mouse

speed mulitplier for X and 50 as the mouse speed mulplier for Y.

The integer number set for the mouse mulplier 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 vercally 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 soware 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 resoluon which will

reference the resoluon number menoned in the // C E command.
