An unused output cable must be terminated by

2.6 Initializing
When all the units in a system have been installed,
the system must be initialized and made ready for use
once. The initialization procedure enables all DCN
units installed to be recognized by the CCU.
Recognition is given in the form of an address,
allocated by the CCU to each active unit in the
system.
See chapter 11 of the DCN Installation and
Operating Manual for how to initialize and assign
seat numbers in a PC-based system.
