Hotkey Port Control

IOGEAR's GCL1908W/GCL1916W provides an extensive, easy-to-use, hotkey function for convenience in controlling and configuring KVM installation from the keyboard. The GCL1908W/GCL1916W provides the following hotkey port control features:

• Selecting the Active Port
  • Auto Scan Mode Switching
• Skip Mode Switching
  • Computer Keyboard/Mouse Reset

The following settings can also be controlled in the Hotkey mode

• Setting the Beeper
• Setting the Quick Hotkey
• Setting the OSD Hotkey
• Setting the Port Operating System
• Restoring the OSD Default Values

Invoke Hotkey Mode

All hotkey operations begin by invoking Hotkey mode. Please make sure that the Hotkey Command Mode function is enabled and that you key in the appropriate Hotkey.

There are 2 possible keystroke sequences used to invoke Hotkey mode, though only one can be operational at any given time:

[Num Lock] + [-]

1. Hold down [Num Lock]
2. Press and release [-]
3. Release [Num Lock]

[Ctrl] + [F12]

1. Hold down [Ctrl]
2. Press and release [F12]
3. Release [Ctrl]

When Hotkey mode is active:

• A command line appears on the monitor screen. The command line prompt is the word Hotkey: in white text on a blue background and displays the subsequent hotkey information that you key in
• Ordinary keyboard and mouse functions are suspended – only hotkey compliant keystrokes (described in the following section) can be entered.

Press [Esc] to exit Hotkey mode

Select the Active Port

Each KVM port is assigned a port ID (see Port ID Numbering). You can directly access any computer on the installation with a hotkey combination that specifies the port ID of the KVM port that a computer is connected to. To access a computer using hotkeys:

1. Invoke hotkey mode with [Num Lock] + [-] or [Ctrl] + [F12] combination
2. Key in the port ID

The port ID numbers display on the command line as you key them in. If you make a mistake, use [Backspace] to erase the wrong number

1. Press [Enter]

After you press [Enter], the KVM focus switches to the designated computer and you automatically exit hotkey mode

Note: In the hotkey mode, KVM focus will not switch to a port if an invalid switch or port number is entered. The hotkey command line will continue to display on the screen until you enter a valid switch and port number combination or exit hotkey mode.

Auto Scan Mode

Auto Scan automatically switches, at regular intervals, among all the KVM ports that have been set as accessible under Scan-Skip Mode, so that their activity can be monitored automatically. See Scan-Skip Mode for more information.

Invoking Auto Scan

To start Auto Scan, key in the following Hotkey combination:

1. Invoke hotkey mode with the [Num Lock] + [-] or [Ctrl] + [F12] combination
2. Press [A] then [Enter], then you will automatically exit hotkey mode and enter Auto Scan mode

- While you are in Auto Scan mode, you can pause the scanning in order to keep the focus on a particular computer either by pressing P or with a left-click of the mouse. During the time that auto-scanning is paused, the command line displays:

Auto Scan: Paused

Pausing when you want to keep the focus on a particular computer is more convenient than exiting Auto Scan because when you resume scanning, you start from where you left off. If, on the other hand, you exited and restarted, scanning would start over from the very first computer on the installation.

To resume Auto Scanning, press any key or left-click. Scanning continues from where it left off

- While Auto Scan mode is in effect, ordinary keyboard and mouse functions are suspended – only Auto Scan mode compliant keystrokes and mouse clicks can be entered. You must exit Auto Scan mode in order to regain normal control of the console.

Note: Auto Scan duration could be adjusted via OSD menu

1. To exit Auto Scan mode press [Esc] or [Spacebar]. Auto-scanning stops when you exit Auto Scan mode.

Skip Mode

This feature allows you to switch between computers in order to monitor them manually. You can dwell on a particular port for as long as you like – as opposed to auto-scanning, which automatically switches after a fixed interval.

To invoke Skip mode, key in the following hotkey combination:

1. Invoke hotkey mode with the [Num Lock] + [-] or [Ctrl] + [F12] combination
2. Key in [Arrow]

- Where [Arrow] refers to one of the arrow keys. After you press an arrow, you automatically exit hotkey mode and enter Skip mode where you can switch ports as follows:

←	Skips to the first accessible port. See Scan/Skip Mode for more details
→	Skips to the next accessible port

• Once you are in Skip mode, you can keep on skipping by pressing the arrow keys. You do not have to use [Num Lock] + [-] combination again
