Other Status menus such as the Status Only menus discussed in section 8.2 and the
Ancillary Data Status menu discussed in section 8.2/8.8 will also prove to be useful
during fault finding.
It is also useful to listen to any valid audio destination with a pair of headphones using the
audio monitoring facility discussed in section 8.5
If the Auto menu is left as the default for the card edge display, (All MENU levers UP,
SEL position 0), then the first three status menus will be displayed on a priority basis.
This will provide continuous monitoring of SDI signal status, AES and Ref I/P status and
whether any active audio channels fall silent (<50dB FS). This is recommended for
normal operation.
