OPERATION

This KVM supports several different methods for switching focus from one PC to another.

Manual Front Panel

The most basic method is to press one of the PC# buttons on the front panel to directly select the corresponding PC.

IR Remote Control

The remote control offers two ways to select a PC.

• Press one of the numbered buttons to directly select the corresponding PC.
• Press the ◄ button to cycle backward through the connected PCs. Press the ► button to cycle forward through the connected PCs. The forward cycle order is PC1 > PC2 > PC3 > PC4 > PC1 > etc.

Mouse Traverse

Put the mouse cursor on the right side of the screen, then move it to the right for about 2 seconds. The KVM will automatically cycle forward to the next connected PC. The forward cycle order is PC1 > PC2 > PC3 > PC4 > PC1 > etc.

USB Port Detection

The KVM monitors the USB ports to each PC to detect the presence of a signal and will switch the selected PC in one of the following ways.

• If the currently selected PC is powered off or the USB connection is broken, the KVM will cycle forward to the next available PC. While searching for an available connection, the Select LEDs on the front panel will flash sequentially in a loop. Once a PC connection is found and the PC connection is established, the corresponding Select LED on the front panel will illuminate. The forward cycle order is PC1 > PC2 > PC3 > PC4 > PC1 > etc.
• If a PC is powered on or a USB connection is established, the KVM will automatically switch focus to that PC.

Hotkey Selection

Use one of the hotkey sequences on the keyboard connected to one of the USB ports on the rear panel to activate various functions. A keyboard plugged into one of the front panel USB ports cannot be used to issue hotkey sequences. Each hotkey command begins with pressing the Scroll Lock (SL) key twice, followed by one or more other keys, all of which must occur within 5 seconds, from beginning to end. This will be represented in the following table with SL+SL+X, where X is the one or more keys that constitute the actual command. If more than 5 seconds elapse without issuing a valid command, the existing command elements will be discarded. Refer to the following table for the various hotkey commands and an explanation of what they do. Note that the commands are not case sensitive and that the case used in the commands are mixed for clarity.

SL+SL+s

| Enable Automatic Switching Mode. The KVM will automatically switch the HDMI ®, MICROPHONE , and SPEAKERS inputs from one to another without changing the USB connection, staying on each input for the interval amount of time (default 15 seconds). Press the SPACE BAR when an input is displayed to select that input. Press any other key to return to the input that was selected before Automatic Switching Mode was enabled. When Automatic Switching Mode is enabled, the Select LED corresponding to the currently displayed input will flash.
---|---
SL+SL+i+#+ENTER| Set the Automatic Switching Mode Interval, where # is 5-999 seconds (default 15 seconds).

SL+SL+b+#

| Enables or disables the buzzer that sounds when switching to PC1, PC2, PC3, or PC4, where # is 1 (on) or 0 (off) (default on).
