Word clock is used for synchronisation only, it does not carry digital data.

Word Clock Outputs

The unit has eight identical Word Clock Outputs (G), all of which carry standard word clock at either

44.1kHz or 48kHz.

Ref Input

The Ref In connector (H) allows the unit to be locked to an accurate external reference, such as an

atomic clock or a GPS clock. With the Coupling menu page set to TTL, the unit will lock to an external

word clock at 32, 44.1, 48, 88.2 or 96kHz. With the Coupling menu page set to Bipolar, the unit will

lock to a 10MHz reference.

As the Scarlatti Clock is a grade 1 master clock, there is nothing to be gained by locking it to a less

stable or less accurate reference!

1394 Interface

There is provision for fitting an IEEE 1394 interface (I), which may be added at a later date. As a

Master Clock does not generate or accept digital data, this will be used for control purposes only.

SUC Connector

The SUC connector (J) is an RS232 interface, primarily used to remotely control the unit during

automated testing. Please contact dCS for advice on using this interface with a household automation

system. Note that we recommend using infra-red remote control instead.

Mains inlet

Power is connected via a standard IEC320 connector (K), protected by a fuse (L) and isolated by a 2-

pole power switch (M).
