Section 4 System Components

Centuri – DSP Card

The DSP cards supply the signal processing function for the Centuri system. Each card provides 32 channels of processing. DSP cards are all the same and do not require configuration, they can therefore be fitted into any of the first 5 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 C100

(1) The ethernet con nection is us ed fo r S SL con trol informa tion, it is no t TCP/IP protocol. Do not combine w ith 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 n umbers 1 and 2 are us ed as these cont ain sufficient capacity for the largest C100 console.

The ‘Machine Control’ and ‘Timecode’ connectors are not used by C100.

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. T he second is to provide access to t he opt ical audio int erfaces to the s tageboxes and/or MORSE router (if specified). These optical audio connections are called Fibre Links and there can be from 1 to 4 fitted to the Routing card. Fibre Links are cost options and should be specified at the time of order. Note that each fibre link comprises two individual fibre optic connectors – one each for send and for receive.

Fibrelinks are available as either m ultimode or singlemode versions. The multimode link can be used for cable lengths of up to 550m and the singlemode version for up to 2km.

If no fibre links are specified then the two cutouts in the front panel will be fitted with blanks.
