Multi-CCU Set-up for the first-time.
11.3 Multi-CCU Set-up for the first-time.
Proceed as follows:
1. Install the PC-card LBB 3511/00 into the master PC used for the multi-CCU system. Ensure that
all DIP-switches and jumpers are set correctly.
2. Ensure that all units are connected correctly, and that the multi-CCU’s and master PC are con-
nected to a network as shown in Chapter 10., FIG 10-20.
3. Each CCU connected to the network must have its own unique address. To set the address,
remove the cover from the multi-CCU and locate DIP-switch S12 located on the ‘Multi-trunk
Board’. To set the address see Chapter 4.7, the range of addresses can be set between 0 to 31.
4. Switch-on each CCU one-by-one and ensure that they are in the ‘Single’ mode. The ‘Single’ mode
is selected by pressing the ‘System’ push-button located on the units front panel for at least 3-sec-
onds (refer to FIG 11-2 ).
5. Initialize all connected units according to the standard procedure as described in Chapter 11.1.
6. Once all units have been initialized, the PC’s operating system software OS/2 and the ‘Multi-CCU
system software LBB 3586/00 must be installed. Refer to the relevant documentation when
installing the OS/2 system software and the Multi-CCU software. Once installed the system can
be configured according to the user manual delivered with the Multi-CCU software LBB 3586/00.
7. When starting the OS/2 master software, or selecting the ‘Operate’ menu-item in the master
software, all connected CCU’s will switch to ‘multi-CCU’ mode. Check that when changing the
operation mode on one of the connected ‘multi-CCU’s’, the other ‘multi-CCU’s’ are also affected.
Check that the microphones on all the connected CCU’s are operational.
NOTES:
1. Switching a CCU to ‘Single-mode’ is only possible when the OS/2 master software is
not running.
2. When switching OFF the master PC (Multi-CCU) all system mode LED’s will begin to
flash, indicating that selection of the ‘Single-CCU’ mode on the CCU is possible.
Connected units are disabled when their is a flashing LED.
11.3.1 Downloading Control PC-software
Before you begin to work for the first time, ensure that all CCU’s have the same firmware. To
download the software from the DCN control PC to all CCU’s in the system, select the ‘Single’ mode.
To download the software to individual CCU’s, connect the DCN control PC to one of the CCU’s
and download the software as described in the ‘Software User Documentation’. Once done for the
first CCU, connect the DCN control PC to the next CCU and download the software again. Repeat
this procedure for all CCU’s connected to the system. Once the software has been downloaded to all
CCU’s, connect the DCN control PC (if needed) to your preferred and configured CCU and select
the ‘Operate’ mode on the master PC.
If you are using a DCN control PC, check in the ‘System Config !’ window’ of the “Startup” software
that all connected units and the PC-card (when used) are present. To create ‘Installation’ and ‘Names’
files use the procedures as used for a single-CCU system. These procedures and descriptions of the
relevant software applications, LBB 3580, LBB 3585 and LBB 3590 can be found in their respective
software manuals.
11.4 Maintenance Menu
Central Control Units (CCU) with version 4.0 software and higher comprise additional embedded
software. This software introduces a ‘Maintenance Menu’ for a ‘Stand-alone’ system. Using this menu
the following default options can be set:
• Default language for the delegate/chairman’s unit LC-displays
• Assign ‘Stand-alone’ intercom operator.
NOTE: The DCN PC software will terminate if the maintenance mode is selected.
The maintenance menu sets the internal settings for the CCU’s ‘stand-alone’ operation and can only
be entered when the CCU is running in ‘stand-alone’ mode (either ‘Single’ or ‘Multi’-CCU). The
maintenance menu is entered by pressing and holding down for at least 3 seconds, one of the
following button-combinations.’
• Active Micro’s + Operation button or
• Active Micro’s + Equalizer On button or
• Operation + Equalizer start button.
Once the maintenance menu has been entered into, all units equipped with an LC-display (except
Interpreter units) will display the ‘Maintenance Menu. Once displayed all congress activities will stop
and all CCU control panel LEDs will flash.
While in the ‘Maintenance Menu” select a unit to set the menu options. The unit chosen will set the
menu options for all connected units. Once a button on the selected unit has been pressed, then LC-
display of all other units will be cleared.
