Central Control Unit (Com - ports) LBB3500/15 2 x 9-pin Sub-D connector RS 232 for: Facilities factory testing (diagnostics) direct PC control camera control remote control (Open interface) applications for: - Mimic panel (Microphone control) - Voting panel - Attendance registration - Intercom - Message Distribution I&O Manual 08.12.2004 DCN SPCC PO CCE

Central Control Unit (Com - ports) LBB3500/15 Open interface applications for remote controller The DCN system provides a facility for controlling microphones, microphone management modes, attendance registration and voting from a remote controller. The remote controller can be custom built for a given application to control microphone activity - for example a push- button panel, with on/ off push-buttons and indicator. LEDs assigned to each microphone position can be used to control delegates microphones from a remote position. The communication protocol is message based binary interface (i. e remote functions and update information). Note: Before third parties can use the remote interface, the interface must be enabled on the CCU by installing the LBB3587 key-disk. - Only possible by using the LBB 3500/15 or /35 08.12.2004 DCN SPCC PO CCE

Central Control Unit (Com - ports) LBB3500/15 LBB 3500/ 15 and LBB 3500/ 35 (TCB 4) Port 1 : DCN Control PC Port 2 : Camera Control In a single (stand- alone) CCU system two serial COM- ports (Port 1 and Port 2) are available. Both ports can be individually configured. NOTE: It is possible to select ‘Full’ protocol on both Port 1 and Port 2. However this is NOT recommended due to processing power and memory limitations. Default settings are; 8 data bits No parity check 1 Stop bit 08.12.2004 DCN SPCC PO CCE
