focus to the computer on the selected port.
Press and hold port selection buttons 1 and 2 for more than 2 seconds to start Auto Scan Mode.
14
Mouse Port Switching
The KVM supports the very latest in mouse port-switching – simply double-click the scroll wheel of your
USB mouse to cycle through the ports.
Note: 1. This featured is only supported by USB 3-key scroll wheel mice.
2. The default setting is disabled.
3. This feature is only supported when Mouse Emulation is enabled.
See Mouse Emulation Control for details
Hotkey switching
All port switching begins by tapping the Scroll Lock key twice. The tables below describe the actions
that each combination performs.
Note:
If the Scroll Lock key conicts with programs running on the computer, or your keyboard does not have
a Scroll Lock, see the section titled Advanced Switching to use the alternate switching method.

Port ID Numbering
Each CPU port on the switch is assigned a port number. The port numbers are marked on the rear
panel of the switch and each switch LED has a corresponding number for easy identication.
The Port ID of a computer is derived from the CPU port number it is connected to. For example, a
computer connected to CPU port 2 has a Port ID of 2.
The Port ID is used to specify which computer gets the KVM, USB peripheral, and / or audio focus
with the Hotkey port selection method.

Auto Scanning
The GCS1782G’s Auto Scan feature automatically cycles the KVM focus through the computer ports
at regular intervals. This allows you to monitor computer activity without having to switch from port
to port manually.
Note:
1. The n stands for the number of seconds that the GCS1782G should dwell on a port before
moving on to the next. Replace the n with a number between 1 and 99 when entering this hotkey
combination.
2. 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 input. You must exit Auto Scan
Mode in order to regain normal control of the console (hit the space bar or the Esc key).
3. Although the video focus switches from port to port, the keyboard, mouse, and USB focus do not
switch. They remain on the port where Auto Scanning began.

Hotkey Setting Mode
In some instances the default hotkey settings conict with programs running on your computer, and in
some instances the default hotkeys either do not exist on your keyboard (MAC keyboards for instance
do not have a Scroll Lock key), or are inconvenient to use, so The Hotkey Setting Mode allows you to
select alternate congurations for the KVM’s hotkeys.
When HSM is active, the Caps Lock, and Scroll Lock LEDs ash in succession to indicate that HSM is
in effect. They stop ashing and revert to normal status when you exit HSM.
Ordinary keyboard and mouse functions are suspended – only Hotkey compliant keystrokes and
mouse clicks (described in the sections that follow), can be input.
At the conclusion of some hotkey operations, you automatically exit hotkey mode. With some
operations, you must exit manually. To exit HSM manually, press the Esc key, or the Spacebar.
