TwidoPort (499TWD01100) Exec and Kernel Upgrade Procedure to Version 3.02

Facts and Changes

It is necessary to turn off all firewall services in the PC before continuing this procedure.  Active firewalls may not allow the files to download.
Users of the KernelKiller utility should connect to the target TwidoPort via a Hub or a Switch to ensure that the KernelKiller utility is running in Half-Duplex mode.  The KernelKiller utility will not successfully complete the operation otherwise.

Create a directory to place the required files.  From that directory, run your FTP and Telnet sessions.

You should have a functioning TwidoPort at a known IP Configuration to begin this process.

The upgrade must be performed on the local network of the TwidoPort.  The KernelKiller does not work through a router.

Do not use the default IP address of the TwidoPort when doing an upgrade to the latest version if the TwidoPort contains Exec. version 1.6.  Using the default IP may cause the TwidoPort to crash and will be unrecoverable.  Any other assigned IP may be used.

Before proceeding with the test, it is essential to know the IP address of the unit.  The procedure will not work if anything happens where the link is lost.  If this occurs, the module can be power cycled and the test restarted using the assigned IP.
