Upgrading Firmware
Occasionally, it may be necessary to upgrade the firmware on the RB-SC2 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.
The firmware is upgraded using the Serial Control Interface - SCI. This PC software
downloads the new firmware and initiates the upgrade process. To upgrade the firmware,
select the required firmware file in the SCI upgrade firmware section. The RB-SC2 will
automatically reboot and enter the bootstrap mode prior to the transfer of the firmware file.
The SCI software downloads the firmware to internal memory, and then erases the current
firmware before programming the update. When the firmware is complete, the unit reboots
with the new firmware.
Please note: Firmware files can take several minutes to transfer to the RB-SC2 at lower
baud rates. To speed up the process, select a higher baud rate prior to transferring the new
firmware.
