Occasionally, it may be necessary to upgrade the firmware on the Reference Monitor
Meters to add new functionality and fix software bugs. New firmware updates will be made
available from time to time on the Sonifex website. Visit www.sonifex.co.uk for details.
It is vital that neither the serial connection nor mains power to the unit should be
interrupted during the update process. If this should happen, or the update is unsuccessful
for any other reason, the Reference Monitor Meters will not operate normally and will
instead enter a protected Bootloader mode. In this mode, the unit has a limited command
set and will await a successful retry of the update process.
Should the firmware update appear to succeed but the unit not behave as expected,
the update may be repeated either via the DWN: command (if the unit will respond to
commands) or, in extreme circumstances, by setting DIPSwitch number 8 in the “Settings
1” Bank to ON. This action will force the Bootloader to run and allow initiation of an update
under any circumstances. After completion of the update, the switch should be returned to
the OFF position.
To upgrade the firmware on the connected Reference Monitor Meters, click on the Update
Firmware button and select the required firmware file. The new firmware is transferred, and
then the current firmware is erased before programming the update.
