WORD CLOCK Connection ([WORD CLOCK] Connectors)Word clock signals are transferred to and from external devices via the [WORD CLOCK IN] and [WORD
CLOCK OUT] connectors. The [WORD CLOCK OUT] connector can be used to supply the DME64N/24N
word clock to external equipment. Word clock is continuously output by the DME64N/24N during normal
operation. The word clock signal from an external device can be received via the [WORD CLOCK IN]
connector. Refer to the Utility display WCLK page described on page 50 of this manual for details.
To distribute the word clock signal from one device to multiple slave devices, either a word clock
distribution box or daisy-chained connection can be used.

NOTE
Word clock can also be received and transmitted via a mini-YGDAI card installed in an I/O slot, or the
[CASCADE IN] and [CASCADE OUT] connectors. It is necessary to specify whether the DME64N/24N will use
the internal word clock or an external word clock for synchronization.
NOTE
A device transmitting the word clock signal that will be used by other devices for synchronization is the “word
clock master,” while devices received the word clock are “word clock slaves.”
NOTE
This method is not recommended for large systems.
