Hardware Setup
Make sure that power to all the devices you will be installing has been turned off. You must
unplug the power cords of any computers that have the Keyboard Power On function.
Cable Connection
To set up your GCS1782 installation, refer to the installation diagrams on the following pages
(the numbers in the diagrams correspond to the steps, below), and do the following:
1. Connect your USB keyboard and mouse into the USB Console Ports located on the unit’s back
panel.
2. Connect your microphone, speakers, and monitor into the Console ports located on the unit’s
rear panel
Note: The IOGEAR KVM cable set provided 2.1 channel surround sound only. You must use the
included audio cable for 7.1 audio
3. Using the KVM cable set, connect the DVI connector into any available DVI socket in the CPU
Port setion of the switch, then connect the accompanying USB, microphone and speaker
connectors into their corresponding USB, microphone, and speaker sockets.

12
4. At the other end of the cable, connect the
USB, video, microphone, and speaker
cables into their respective ports.
5. Connect your USB peripherals into the type
A sockets (one is located on the front, the
second is located on the rear).
6. Connect the power adapter that came with
your switch into the jack on the switch then
connect the adapter to an AC power source.
7. Verify your connections: ports are correct
and that the Icons match the connection
type.

There are three convenient methods to access the computers: Manual – which involves pressing
the port selection buttons located on the unit’s front panel; Mouse – which involves double clicking
the scroll wheel of the mouse; and Hotkey – which involves entering key combinations from
the keyboard.
Manual port selection
Press and release a port selection button to focus the computer on the corresponding port. The
USB and Audio focus do not change (expect a 2 sec delay).
Press a port selection button twice to focus the audio on the corresponding port (expect a 2
sec delay).
Press and hold a port selection button for more than 2 seconds to change KVM, USB, and Audio
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.
Basic Operation

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 conicts 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.

15
* The USB ports cannot be switched independently of each other.
Hotkey Action
[Scroll Lock] [Scroll Lock] [Enter] Increments the KVM, USB, and Audio focus to the
next higher port ( port 4 wraps to 1)
[Scroll Lock] [Scroll Lock] [K] [Enter] Increments only KVM focus to the next port
[Scroll Lock] [Scroll Lock] [U] [Enter] Increments only the USB hub to the next port
[Scroll Lock] [Scroll Lock] [S] [Enter] Increments only Audio to the next port
Cycling though the ports

16
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 identication.
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.
Going Directly to a Port
Note: The nstands for the computer’s Port ID number. Replace the nwith the appropriate Port ID
when entering hotkey combinations

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 nstands for the number of seconds that the GCS1782G should dwell on a port before
moving on to the next. Replace the nwith 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.

19
Hotkey Result
[Scroll Lock] [Scroll Lock] [A] Enter] Invokes Auto Scan. The KVM focus cycles from port to port at
5 second intervals (default interval)
[Scroll Lock] [Scroll Lock] [A] [n] Enter] The KVM focus cycles from port to port at nsecond intervals.

Hotkey Setting Mode
In some instances the default hotkey settings conict 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 congurations 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.
