It
is important to power up the various router levels in the correct order to
ensure a complete re-configure. The slave levels should be powered up first
and then the master. If slave levels are powered up after the master then
the master will fail to recognise these levels.
The controller will periodically check the handshakes to ensure all modules are
present and functional. If any handshake errors are detected then the card error
LED 6 is lit to indicate this.
If cards are removed from a configured system, then all routes pertaining to that
card will be continuously updated until the card is replaced and a handshake
detected. The updating task will continue for a few seconds after the card is
replaced to allow for full card insertion.
If extra cards are installed, the control card ignores them until the system is re­
configured .
A user can invoke a re-configure by entering a command via the terminal interface
(lM,level,C). This gives the option to re-configure all levels or just a single level.
When handshakes are re-configured the system will automatically reset .
• 6.4 Defining stereo analogue audio
parameters
There are a number of programmable features associated with setting cross points
on Freeway Stereo analogue audio routers. They are:
• left to both/right to both. This is a source oriented feature whereby one
channel of a stereo source pair is routed to both channels at the output, hence
left to both sees the left channel of a stereo source pair being routed to both
left and right channels at the output. Right to both operates similarly
• mono or summation is a destination oriented feature whereby a stereo source
pair is summed before being routed to a mono destination
• swap is a source or a destination oriented feature whereby the left and right
channels of a stereo source pair are swapped over before being routed to the
output
• a normal source or destination is one that requires no manipulation whilst
being routed, i.e. no changing of channels
The following table defines all possible crosspoint scenarios. The Result column
shows the resultant crosspoint type set from a source and destination with the
features programmed as shown.
