AVC
REALTIME CLOCK BATTERY
The AVC’s internal realtime clock is battery-backed to ensure operation when the unit is not
powered. The battery should last for at least 10 years and is easily replaced when necessary,
replacement battery: Renata CR2032 Lithium Button Cell.
MEMORY CARD
The AVC is shipped with a 4Gbyte Type I Compact Flash card.
The duration of video content that can be stored on a card will vary depending on the MPEG2
bitrate used to encode it. For a 4GB card, capacity could be anything from 60 to 180 minutes.
However, a larger capacity card could of course be fitted if required.
As only the project’s programming data resides on the card, the card is also a convenient way to
backup data for archiving; the Designer project file for example.
Furthermore, in the event of AVC hardware failure, simply moving the card into a replacement
unit with identical or more recent firmware is sufficient to get the project up and running again.
STATUS LEDS
The ETC logo will illuminate when power is applied to the AVC. The red LEDs on the front of
the AVC indicate the unit’s current status.
The Active LED illuminates once the boot up procedure has completed and is indicative of a
fully functional unit.
The Ethernet LED indicates Mosaic-related network activity (not network link) while the
remaining LEDs indicate communication on the various ports of the AVC.
Either the PAL or NTSC LED will illuminate once a valid project file has been loaded from the
memory card and playback & video output has started. The choice of LED will indicate which
video system is being used, this having been configured using the Designer software.
ERROR CODES
Additionally the red status LEDs are used to indicate any boot failures of the AVC that prevent
the unit from going active. These codes are outlined below and in all cases the Active LED will
be off.

batteries according to the manufacturer’s instructions.
