AVC
• Bootloader LED codes:
Ethernet & USB double flashing - failed to boot firmware (use the AVC Firmware Updater
to repair)
NTSC & PAL solid + Ethernet/USB indicating activity - erasing flash (not an error, will
occur when updating firmware)
NTSC & PAL flashing + Ethernet/USB indicating activity - programming flash (not an error,
will occur when updating firmware)
• Firmware LED codes:
Ethernet & USB double flashing + Serial solid - CF card missing (insert or replace the card)
RESET SWITCH
The AVC may be reset by inserting a small blunt object into the reset hole on the front of the
AVC to depress the reset switch. The switch should be held for at least one second.
WATCHDOG
The internal “watchdog” is enabled by default to reset automatically the AVC in case of a
software crash as a result of either a coding error (“bug”) or a random electromagnetic event
such as a power brown-out or spike, nearby lightning strike or static discharge. Please refer to
the Designer Help to learn how to disable this feature (not recommended).
VIDEO SYSTEMS
The AVC supports either the NTSC (525/60) or PAL (625/50) video systems and this
configuration is done using the Designer software and is uploaded as part of the project file.
Video coding: MPEG-2 MP@ML/SP@ML VBR/CBR
Coded frame rate: 29.97fps (525/60, interlaced)
25fps (625/50, interlaced)
Display frame rate: 29.97fps (525/60, interlaced)
25fps (625/50, interlaced)
MPEG-2 resolution: 720x480 & 704x480 (525/60)
720x576 & 704x576 (625/50)
MPEG-2 GOP max: 36fields/18frames (525/60), 30/15 recommended
30fields/15frames (625/50), 24/12 recommended
Aspect ratio: 4:3 or 16:9 anamorphic
NOTE: The reset must not be operated when uploading project data nor during
bootloader/firmware updates to the AVC as corruption of the data or
software may occur, perhaps even rendering the unit inoperable
