9.3.2 Word clock in and out.
On the rear side of the Oxygen 4 Digital you can find two BNC connectors with the text FCLK OUT and
FCLK IN. These are the word clock in/out connection which can be used for synchronization purposes.
If the Oxygen 4 Digital is the last in the synchronization chain, you can use the TERM. switch to terminate the
line. (75 Ohm Termination)
