NOTE:
It is important that a VCX-2400 device that has a
Failed
status
NOT
be turned off or
rebooted. At the point that the failure occurs the device will not be in a bootable state. If power is
cycled or the firmware cannot be updated without failure after repeated attempts then the
firmware chip will need to be replaced. The 10Mbps revision 2.5 devices (in current production)
have removable chips that can be replaced in the field. The 100Mbps revision 3.0 devices must
be reprogrammed at the factory. Since revision 3.0 is not yet in production there may be other
safeguards, such as automatic firmware backup that may modify these instructions.
When a device is in the process of upgrading, the Activity screen will show the progress as a
percent of complete for each stage. There are four stages.. 1) Erasing, 2) Startup Code, 3)
Application Code, and 4) FPGA. When erasing the progress may not update but erasure will
compete in a few seconds. The startup code frequently completes so quickly that you don’t see it
in the Status column.
After the FPGA status reaches completion you should see the Status column change to
Complete.
If it changes to
Failed
at any time during the firmware update you will need to retry
updating the firmware for that unit before cycling power or rebooting.
The
Clear Complete
button will clear the list display of any operations that did not fail. The
Clear Failed button will clear the list display of any failed operations.
The Initiate Update
will
Broadcast a command to all online units to connect to the update server to perform a firmware
update. Normally the update server will be the computer that is running VcxNetBurner. However
it would be possible to have VCX-2400 devices configured to use a different server. When
Initiate Update
is pressed, all of the VCX-2400 devices within range of multicast packets will
connect to its preset update server.
VCX2400D Screen
The VCX2400D is accessed through the VCX-2400D tab and displays the parameters used to
select the version of the firmware sent to VCX-2400 decoder devices. This information is
imported from a import.ini file that is provided with each firmware update. This screen allows
the operator to see what update is selected. It is important to confirm that the files indicated in
the file selection boxes are located on your computer. The import file is selected using the
