6.2 Understanding the database
The editable database, which is held in non-volatile RAM in the Axis control card,
determines the operation of the system and its associated panels.
To understand its use, a number of terms have to be defined:
• level - this term describes a type of router e.g. video or audio level.
• source - this term is used to describe an input of a router.
• destination - this term is used to describe an output of a router.
To configure a system the following parameters within the database must be considered:
• level type
• source and destination associations
• source names and destination association names
• route inhibit tables per level
• keypad and panel configuration
• general remote port configuration
• trigger method selection per source per level
• audio features per source per level
6.2.1 Level types
The level type within the Axis database defines the router type used on that level, permitting
advanced features such as audio parameters to be used. It also defines the shape of a
router level for example where it is used as a dual, triple or quad split for dual channel
audio, YUV or RGBS operation.
6.2.2 Source and destination associations
This is a method of setting a group of associated sources on different levels to a group of
associated destinations from a single button on a control panel. This is fundamental to the
operation of the database.
For example, a destination association defines the destinations on each level that feed into
a device, say a record VTR. Similarly, a source association defines the sources that
originate from a device, say a playback VTR. An association is assigned a unique number,
referred to as an index.
An example of this is:
