Firmware Upgrade  
The Window-based Firmware Upgrade Utility (FWUprade.exe) provides a smooth, automated process for  
upgrading the GCS1924 firmware.  
Note: In order to perform a firmware upgrade, you need to use a computer thats not connected to the  
KVM.  
Step 1  
Connect a USB cable to any open USB port of the KVM and the any open USB port on the computer.  
Connect power adapter to your power outlet and the KVM.  
Step 2  
upgrade to the computer.  
Step 3  
Shut down all the computers that are connected to the KVM. Then Invoke Firmware Upgrade Mode.  
(Please refer to Hotkeys Setting Mode section.) The front panel LEDs flash together to indicate Firmware  
Upgrade Mode is in effect.  
27  
 
Step 4  
Extract the file with WinRAR or compatible  
software. Then double click on the execute  
file to begin with the Firmware Upgrade Utility.  
Step 5  
The Firmware Upgrade Utility welcome screen  
appears. Read the License Agreement and  
click “I Agree” then click “Next” if you wish  
to continue with the firmware upgrade.  
Otherwise, click “Cancel” to exit.  
28  
 
Step 6  
Choose the correct KVM that you wish to  
perform firmware upgrade from the “Device  
List” and then click “Next” to continue. Then  
the Firmware Upgrade Utility will verify if there  
is a KVM connected to the computer by the  
firmware upgrade cable. (Check Firmware  
Version checkbox is optional)  
29  
 
Step 7  
If you have checked the “Check Firmware Version” checkbox, then the utility will check the current firmware  
that is on your KVM. If the current firmware is newer than the firmware that you wish to upgrade to, a window  
will popup and prompt you to ask if you wish to proceed. Simply click “Yes” to start the upgrade and “No”  
to cancel the upgrade.  
Note: If you did not check the “Check Firmware Version” checkbox, utility will perform the upgrade  
automatically no matter what version of firmware you have in the KVM.  
30  
 
Step 8  
When the firmware upgrade is done, you will  
see “Firmware upgrade OK” in the “Status  
Messages” window. Then simply click “Finish”  
to complete the whole firmware upgrade  
process.  
Final Step  
Now the KVM will reset by itself and it will be  
ready for usage after the rest.  
Note: If you see warring message of Mac O.S.  
version incompatible, please contact IOGEAR  
service staff for latest firmware upgrade tool  
31  
 
Upgrade Fail  
If you don’t see “Firmware upgrade OK” in the “Status Messages” window, it means the utility has failed to  
complete the firmware successfully. If that occurs, please do the following:  
Step 1  
Unplug all USB cables and DC power adapter from GCS1924.  
Step 2  
Plug single USB cable in the last CPU port with PC powered on.  
Step 3
