Centuri – DSP Card
The DSP cards supply the signal processing function for the Centuri system. Each card provides 32 channels of processing
at 48kHz. or 16 channels of processing at 96kHz. DSP cards are all the same and do not require configuration.They can
therefore be fitted into any of the appropriate slots in the front of the Centuri rack.
For a system to pass any audio, there must a card fitted in slot 5 and a card in slot 1.
Centuri – Disk Card
This is a 1.5 width card which is always fitted in the right-hand slot (slot 11) of the front card-cage. It houses the system
hard-disk.This card is not fitted if the dual redundant disk option is specified. In this case a blank panel is fitted and the
system discs are mounted internally in the space beneath the power supplies.A front panel key switch is provided to select
which disk is in use.
Centuri – CPU Card
The Centuri Processor is always fitted with the CPU card. It must be fitted to the left-most rear slot.
The CPU card is fitted with connectors for the following functions:
Ethernet – 100baseT console network
(1)
Video 1–3 – Display output for the Centre Section monitor.
Sync – Video sync input.Video black & burst is required for system reference.
Serial – 62-pin connector providing eight RS422/RS232 serial ports.An adaptor cable breaking out to eight
off 9-way D-type male connectors, labelled ‘TTY-A’ to ‘TTY-G’, is provided.
TTY-B: - - Keyboard (RS422)
TTY-C: - - Touchscreen data (RS422)
TTY-G: - - Bitpad (RS422)
TTY-E: - - Console (RS232) – Connection for data terminal
TTY-A, D, F & H Unused on C200
(1)
The ethernet connection is used for SSL control information, it is not TCP/IP protocol. Do not combine with proprietary
networks. Standard ethernet repeaters can be used.
Centuri – Console Interface Card
The Centuri Processor is always fitted with one Interface card. It must be fitted to the rear of the card-cage next to the
CPU card.
The card provides the connection to the console’s control surface and handles all switch and lamp signals. Of the three
‘Control Surface’ connectors, only numbers 1 and 2 are used as these contain sufficient capacity for the largest C200
console.
This card also provides the parallel ‘Machine Control’ and ‘Timecode’.
Centuri – Routing/Link Card
The Centuri is always fitted with a Routing/Link card. It must be fitted to the rear card-cage in position 5.
This card has two functions.The first is an internal function to organise the audio routes across the system’s backplane.
The second is to provide access to the optical audio interfaces to the stageboxes and/or a MORSE system (if specified).
These optical audio connections are called Fibre Links and 1, 2, 3 or 4 can be fitted to the Routing card. Fibre Links are
cost options and should be specified at the time of order. Note that each fibre link connection comprises two pairs of
optical connectors – one for the main link and one for the optional redundant link.
In addition, each Fibre link provides an output of system Wordclock on a separate BNC connector.
Fibrelinks are available as either multimode or singlemode versions.The multimode link can be used for cable lengths of
up to 550m and the singlemode version for up to 2km.
