MultiSmart Installation & Operation Manual
29.2 Enabling Software Modules with a New Site Key
A new Site Key can be obtained from MultiTrode to enable one or more software modules that are currently
disabled. The Site Key is entered via the keypad in a similar way to using a mobile phone, e.g. pressing the
number 3, steps the character displayed through 3,d,e and f. (The Site Code is unique to each MultiSmart
and cannot be changed).
Navigate to:
Figure 176 - Enabling Software Modules
NOTE: The Site Key is based on the serial number of the unit so a different Site Key is required for
each MultiSmart.
30 Upgrading MultiSmart Firmware
30.1 Upgrading via PC Configuration Utility
To upgrade the firmware, insert the SD card or USB 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 SD card or USB. 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 6 minutes.
This is a consequence of having forward 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.
