ensures that the correct version of firmware is saved so that, if an error occurs, the
DIR911 can re-load this previous version and continue operation.
Connect the computer carrying the new firmware upgrade to Port A of the DIR911. The
serial IO configuration of the computer must match the remote control port IO for this to
operate properly. When this is done, press “LOAD” and the LOAD UPGRADE screen
shown below will appear.
LOAD UPGRADE Screen
- Load field firmware upgrade from computer
This screen waits for the data transfer from the external computer to begin. Once the
loading has started, the progress indicator will continue until it reaches just about the
end of the line. If an X appears in the progress indicator, an error has occurred and new
firmware has not been successfully loaded. When the upgrade is successfully loaded,
the unit will reboot with the new firmware version. However, this new version must now
be saved to system ROM. Get back to the UPGRADE screen and press “SAVE”. The
following screen will appear:
SAVE UPGRADE Screen
- Save field firmware upgrade to ROM
Assuming the upgrade has loaded successfully, press “BURN ROM” to save the new
upgrade code as permanent. The following message should appear on the display
“Burning ROM with new code version Will reboot when upgrade complete”. After the
upgrade is saved to ROM and the system reboots, the upgrade is complete. If you do
not want the upgrade, simply press “DO NOTHING” and power the unit off and on
again. This will load the older firmware version and the upgraded version will not be
used.
