Remote Controller
2.  Multi- CCU System
 
A null-modem RS-232 cable is used to connect the ‘Master CCU PC’ to the remote controller.  The 
maximum cable length between the ‘Master CCU PC’ and the ‘Remote controller’ should not exceed 
5 m (16.4 ft.).  Where longer distances are required an ‘interface unit’ should be used to ensure 
correct transmission.  See also
. DCN Control using Personal Computers
NOTES: 
                                                                                                                           
1. The COM-port settings for a Multi-CCU system can be changed.  Refer to the ‘    
‘Readme.txt’ file associated with the LBB 3586 Multi-CCU software package.
2.
The RS232 COM-port on the slave CCU’s is disabled when used in a multi-CCU      
system
3.
The communication protocol and a higher baud-rate for the serial COM-port can be 
adjusted as necessary (see 
and
).
10.9.2  Typical examples using the Remote Controller
1. Assigning Microphones to push-button on the remote controller
In order to assign microphones to push-button on the remote controller panel, a push-button should 
first be assigned for switching the remote controller between the ‘Installation and Operational’ mode. 
To assign push-button to microphones, the remote controller should be switched to the ‘installation’ 
mode. Once in the installation mode, press the microphone button of the unit in the hall to be 
assigned,  and then press its corresponding push-button (i.e. for microphone 2 press the push-button 
marked 2 etc..) and so on till all microphones have been assigned.
2. Assigning Microphone Management Modes and No. of active microphones. 
Using the RS-232 capability the functions of the CCU can be simulated on the remote controller - for 
example: ‘Active Micros ( the number of microphones which can be activated simultaneously) can be 
selected, and the ‘Operation’ mode (microphone operational modes: ‘Open’, ‘Override’ and ‘Voice’) 
can also be selected. 
Other examples are also possible. Further information about additional remote control functions and 
the communication protocol is available on request.
