Updating the Firmware
The AN-X4 firmware files are supplied in files that begin with AN-X4 and have extension qtf.
AN-X4 can have multiple versions of the same firmware, for example, different versions of the
the Data Highway Plus qtf. You can use the web interface to:
download firmware files to the AN-X4
select which version is to run
remove firmware files using the web interface.
Run the command Administration/Select AN-X Firmware to select the file you wish to run.
WARNING!
Do not update firmware to the AN-X while applications that use the
AN-X are running.
You must restart the AN-X4 to run the firmware that you selected or transferred to the AN-X.
WARNING!
It is essential that you do not disrupt power while updating firmware,
especially maintenance firmware, to the AN-X4 or while the AN-X4 is
restarting following a firmware update.
Interrupting power at some points in the update process could render the
AN-X inoperative and it would have to be returned to the factory for
reinitialization.
You can also copy firmware files to the directory /Firmware on the microSD card using a card
reader in your computer. If you do so, you will also need to update the file FirmwareCfg.txt in the
same directory to run the file you copied over. The contents of FirmwareCfg.txt must match
exactly the name of one of the firmware files on the AN-X, including the version.
Example
AN-X4-AB-DHP.v4.12.54.qtf
