29 Upgrading MultiSmart Firmware

29.1 Upgrading Firmware

Firmware can be upgraded via a Compact Flash card, or using the PC Upgrade Utility.
Upgrades of firmware do not overwrite the existing configuration. Any new tags which are available in the
system are simply set to their new default value.
An automatic DSP upgrade (of the DSP board) is performed at the end of the firmware upgrade. This
behaviour can be changed by setting the following parameter in the Advanced menu.

29.2 Upgrading via PC Configuration Utility

To upgrade the firmware insert the compact flash card into the MultiSmart unit and restart (see Section 27). It
is recommended to save your current configuration prior to commencing a firmware upgrade
The MultiSmart displays a firmware update prompt with the version information of the current version and the
update image present on the CF card. If neither option is selected after a predefined time period, the
MultiSmart resumes normal operation without performing a firmware upgrade.
The unit uses the file of upgrade image to upgrade to the latest version of firmware. The existing
configuration is preserved. After the new firmware is installed, the MultiSmart automatically upgrades the
existing configuration to the latest firmware version.
NOTE:
This process takes approximately 10 minutes. This is a consequence of having forwards and
backwards compatibility. MultiSmart interrogates every tag in the existing configuration and checks
for any new tags in the firmware. Any new tags found are set to the default status.
NOTE:
During the upgrade process, the MultiSmart does not control the pumps so a backup method of level
monitoring and pump control may be required.
