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.

13
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
8. Power on the computers.

Manual Switching
There are two convenient methods to access the computers: Manual – pressing the port selection
pushbuttons located on the unit’s front panel; and Hotkey – entering key combinations from the
keyboard. Hotkey port selection is discussed in the next chapter.
Manual port selection:
Press and release a port selection pushbutton 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 pushbutton twice to focus the audio on the corresponding port (expect a 2
sec delay).
Press and hold a port selection pushbutton for more than 2 seconds to focus KVM, USB, Audio and
the computer on the corresponding port.
Press and hold port selection pushbuttons 1 and 2 for more than 2 seconds to start Auto Scan
Mode, at 5seconds dwell time (default).
Basic Operation

15
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 other programs running on the computer, see the section titled
Advanced Switching to switch to the alternate method.
Cycling though the ports
Hotkey Action
[Scroll Lock] [Scroll Lock] [Enter] Increments the KVM, USB, and Audio focus to the next
higher port (GCS1784 - 4 wraps to 1)
[Scroll Lock] [Scroll Lock] [K] [Enter] Increments only KVM to the next port
[Scroll Lock] [Scroll Lock] [U] [Enter] Increments only USB to the next port*
[Scroll Lock] [Scroll Lock] [S] [Enter] Increments only Audio to the next port
* The USB ports are locked together, therefore they cannot be independently switched.

Port ID Numbering
Each CPU port on the switch is assigned a port number (1 or 2 for the GCS1782 and 1,2,2,4 for the
GCS1784). 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 GCS1782’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 CS1782 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 when Auto Scanning began.

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.
