FIRMWARE UPDATE
5.1.
Introduction
HQView-3xx has an USB port which allows a PC connection. With the Calibre PC Updater tool new
firmware can be installed on HQView-3xx for feature upgrades and bug fixes.
5.2.
Updating Firmware
HQView-3xx accepts firmware downloads in a dedicated Updater mode. The unit is put in Updater
mode by pressing and keeping the Menu key pressed at power up. If the Menu key is released within 10
seconds after power up HQView-3xx is in Updater mode. Otherwise, HQView-3xx is started normally.
Whilst the Menu key is still pressed the RGB(S) input channel LEDs are flashing. When in Updater
mode the RGB(S) input channel LEDs are flashing two times, then switched off, then flashing two times
again, then switched off and so forth. Now the USB connection between PC and HQView-3xx needs to
be established and the Calibre PC Updater tool to be started. The PC Updater tool allows to browse and
select a firmware file in BREC format. Once a BREC is selected the Update Firmware button has to be
pressed and the firmware download to the HQView-3xx into non volatile flash RAM starts. After
completion of the download HQView-3xx needs to be restarted normally (without pressing the Menu
key) for the change to take effect.
