3. Security Systems BU Communication Systems ST/SEU-CO 3 DCN SA IO Installing 06.12.2004 Initializing a System Introduction When all the units in a system have been installed, the system must be initialised and made ready for use. The initialisation procedure enables all DCN units installed to be recognised by the CCU. Recognition is given in the form of an address, allocated by the CCU to each active unit in the system. A ‘de- init’ switch located under each DCN contribution unit is used to clear the units allocated address when conflicts with duplicated addresses occur. The following describes how to initialise a ‘Stand- alone’ and PC- based system. Initialising a stand- alone system Note: Step 1 is normally not required for systems powered- up for the first time. First time systems are de- initialised, therefore proceed with step 3 after switching on the CCU. Step 1 On the CCU locate the push- button and the small recessed switch (Start) under ‘Equalizer’. Using a small pointed device (e. g. paper- clip) insert the device into the recess hole (3) and activate the switch while holding down the equaliser ‘Start’ switch and ‘Equaliser’ push- button for at least 10 seconds after switching on the CCU (1). Ensure its power LED is lit (2). DCN units with LC- display show the firmware release version of the unit itself and not the CCU firmware release version!

Note: If this is not the case resume at step 1 again or remove the unit. Step 3 To initialise an individual unit press the units microphone key while the units LEDs are lit (for interpreters desk press the ‘Mute’ key, the Dual Audio Interface Unit and the Multi- Purpose Connection have their own ‘de- init’ but, but can also be initialised by pressing the microphone key of a connected microphone). Once pressed the units LEDs go out. The unit is now recognised in the system by the CCU. Repeat this procedure for all active units installed in the system one by one. Initialise all units one by one (not simultaneously) to eliminate addressing problems. Step 4 To clear the individual address of a delegate/ chairman unit in the event of an address conflict, press the ‘de- init’ switch of the relevant unit.( See Chapter 2.).
