I/O – Digital Input/Output Card 110Ω (SSL ref. 902XF)

The Digital Input Card provides 32 balanced AES/EBU signal pairs of bo th input and output. All circu its are accessed via 25-pin D-type female connectors.

Refer to Appendix C for the connector pinout for this card. Mating connector kits can be ordered for the card.

As in the case of the Analogue I/O, cards added subsequently should be placed to the left of existing cards.

Note. When assigning digital card output channels as insert sends, the routing system will automatically assign the same i nput chann el n umber a s t he corresponding re turn. It is therefore ne cessary to phys ically wire outboar d equipment so that circuit allocation follows this arrangement.

I/O – Digital Input/Output Card 75Ω (SSL ref. 902XJ)

This version of the Digital I/O card is externally identical to the the 110Ω version (apart from its designation number). T he Impedan ce o f eac h input and output c ircuit however, is now 75Ω for correct matching to installations using co-axial cabling.

A separate BNC interface panel is available as a cost option. This is 2U high and is fitted with 64 chassis mounted BNC plugs – 32 input and 32 output. 1metre D25–D25 interconnecting looms are provided.

As in the case of the Analogue I/O, cards added subsequently should be placed to the left of existing cards.

Note. When assigning digital card output channels as insert sends, the routing system will automatically assign the same i nput chann el n umber a s t he corresponding re turn. It is therefore ne cessary to phys ically wire outboar d equipment so that circuit allocation follows this arrangement.

I/O – MADI Card (SSL ref. 902XG copper version / 902XH/K fibre versions)

The MADI I/O card can operate in two ways: either as a 56 channel varispeed I/O (multitrack interface) or as a 64 channel 48kHz link (station router). In either case a source of sync is required. The sync source can be AES, Word sync or self clocked from the MADI bitstream.

The Card is fitted with dual MADI connections – MADI A andMADI B. The outputs are duplicates of the MADI signal so that a safety backup can be made without having to use external distribution. On the input side, MADI A has priority but MADI B will take-over if the A signal is lost.

The fibre version of the card – see page 18 – has duplex SC optical connectors for both MADI A and B. The Fibre type can be either singlemode or multimode (this must be specified at time of order).
