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.
