To upgrade the FLASH code on your KVM Switch, you will first need to obtain the 

latest FLASH firmware revision. It is available online at www.sharkrack.com/kvm.
Next you will need a serial cable (available at most electronics stores) to connect a 

computer to your KVM Switch. Simply connect the serial cable between the SETUP 

port on your KVM Switch to the serial port on the computer.
You will then need some form of terminal software on your attached computer so that 

it can communicate with the KVM Switch. There are several that are commercially 

available. Select one that you are comfortable with and be sure that it can communicate 

at 38,400 baud.
Configure your terminal program to the following settings:
38,400 Baud

8 Bits

No Parity

1 Stop Bit

No Flow Control
Activate the OSD menu on your KVM Switch by tapping the Control key twice. Enter 

twice more to activate the Administrator Commands screen and then select 

“Administrator Functions.”
Use the down arrow key to highlight the menu selection for “FLASH Upgrade”, then 

press Enter.
A menu screen will appear and ask if you wish to continue. You must type out the word 

before proceeding. Once you have done this, the Switch will go into a standby 

mode and wait for data from the computer. 

Note: The keyboard, video and mouse are disabled during the FLASH upgrade.

The final step is to send the FLASH file from your terminal program. To do this, you 

will need to use the transfer function of your communications software. Send the 

FLASH file using the XMODEM protocol. The transfer should be completed within 

four minutes.
The KVM Switch will automatically check the upgrade and make sure that it is valid. 

If the Switch detects an error it will abort the upgrade and prompt you to re-transfer the 

file. Otherwise, it will return the message “Flash Upgrade Successful.”
