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 units back  
panel.  
2. Connect your microphone, speakers, and monitor into the Console ports located on the units rear  
panel  
Note: The IOGEAR KVM cable set provided 2.1 channel surround sound only. You must use the

Basic Operation  
Manual Switching  
There are two convenient methods to access the computers: Manual – pressing the port selection  
pushbuttons located on the units 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).

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 conflicts with other programs running on the computer, see the section titled  
Advanced Switching to switch to the alternate method.

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 identification.  
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 n stands for the computers Port ID number. Replace the n with the appropriate Port ID  
when entering hotkey combinations

Auto Scanning  
The GCS1782s 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 CS1782 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 when Auto Scanning began.

Hotkey Setting Mode  
In some instances the default hotkey settings conflict 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 configurations for the KVMs hotkeys.  
When HSM is active, the Caps Lock, and Scroll Lock LEDs flash in succession to indicate that HSM is  
in effect. They stop flashing 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.

The Firmware Upgrade Utility  
The Windows-based Firmware Upgrade Utility (FWUpgrade.exe) provides a smooth, automated  
process for upgrading the KVM switchs rmware.  
The Utility comes as part of a Firmware Upgrade Package that is specific for each device. New firmware  
upgrade packages are posted on our Website as new firmware revisions become available. Check the  
web site regularly to find the latest packages and information relating to them.  
Before you Begin  
To prepare for the firmware upgrade, do the following:  
1. From a computer that is not part of your KVM installation ( disconnect the computer from the KVM)  
go to our Internet support site and choose the model name that relates to your device (GCS1782)  
to get Firmware Upgrade Packages.  
2. Choose the Firmware Upgrade Package you want to install (usually the most recent), and down-  
load it to your computer.  
3. Use the Firmware Upgrade Cable provided with this unit, to connect a COM port on your computer  
to the Firmware Upgrade Port of your switch.  
4. Shut down the computers on your CS1782 installation.  
5. Invoke Firmware Upgrade Mode.  
The front panel LEDs flash together to indicate Firmware Upgrade Mode is in effect.  
30  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Starting the Upgrade  
To upgrade your firmware:  
1. Run the downloaded Firmware Upgrade Package file – either by double clicking the file icon, or by  
opening a command line and entering the full path to it.  
The Firmware Upgrade Utility Welcome screen appears.  
2. Read the License Agreement (enable the I Agree radio button).  
3. Click Next to continue. The Firmware Upgrade Utility main screen appears.  
The Utility inspects your installation. All the devices capable of being upgraded by the package are  
listed in the Device List panel.  
4. As you select a device in the list, its description appears in the Device Description panel.  
5. After you have made your device selection(s), Click Next to perform the upgrade.  
If you enabled Check Firmware Version, the Utility compares the devices rmware level with that of  
the upgrade files. If it finds that the devices version is higher than the upgrade version, it brings up a  
dialog box informing you of the situation and gives you the option to Continue or Cancel.  
31  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If you didn’t enable Check Firmware Version, the Utility installs the upgrade files without checking  
whether they are a higher level, or not. As the Upgrade proceeds, status messages appear in the  
Status Messages panel, and the progress toward completion is shown on the Progress bar.  
After the upgrade has completed, a screen appears to inform you that the procedure was successful.  
Click Finish to close the Firmware Upgrade Utility.  
After a successful completion, the switches exit Firmware Upgrade Mode, and reset themselves.  
32  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Upgrade Failed  
If the Upgrade Succeeded screen doesn’t appear, it means that the upgrade failed to complete  
successfully, in which case you should do the following:  
1. Power off the CS1782 and remove its housing.  
2. Using a jumper cap, short the jumper on the mainboard labeled J17. The diagram below indicates  
the jumper location on the CS1782 board:  
3. Power on the CS1782. It will now work with the factory default firmware.  
4. Do the firmware upgrade procedure again.  
5. After the upgrade procedure completes, power off the switch, remove the jumper cap from J17,  
close the housing, and power the CS1782 on again.

Troubleshooting  
Symptom  
Possible Cause  
Action  
Mouse / Keyboard not  
responding.  
Improper mouse and/  
or keyboard reset.  
Unplug the cable(s) from the console  
port(s),then plug it/them back in.  
USB devices not  
responding.  
KVM switch needs to  
be reset.  
Power off all devices on the installation. Power  
off the KVM switch; wait five seconds; then  
power up  
There are ghost images  
on the external monitor.  
USB ports need to  
reset.  
Unplug the devices USB cable from the USB  
port on the switchs rear panel, then plug it  
back in.  
PC or OS does not  
support USB 2.0.  
The CS1782 has a built-in USB 2.0 hub, so  
will not support PCs or OS that do not support  
USB 2.0.  
The distance between the external console and the CS1782 is too great.  
The maximum VGA cable distance should not exceed 20m and, in some  
cases, may need to be shorter. Replace the VGA cable with one of an  
appropriately short length.
