LBB 3500/35 Multi
Central Control Unit |
|
|
feature
Extends congress systems by up to 240 contribution
units
Can be used in single or multi-CCU mode
Direct PC control facility
Two RS-232 ports for direct PC control |
|
The LBB 3500/35 is functionally identical to the LBB
3500/15 Central Control Unit (CCU), and is used to
extend the capacity of the DCN system. This unit is
designed for situations where more than 240
contribution units are required. Multi-CCU systems
are controlled from a separate, dedicated PC running
the Multi-CCU software (LBB 3586) and equipped with
the LBB 3511/00 PC Card. |

LBB 3506/00
Extension Power Supply Unit |
|
|
feature
Powers up to 180 additional contribution units
Remote mains on/off
Easy connection to DCN
|
|
The Extension Power Supply unit is used in
combination with a CCU to supply power to a maximum
of 180 additional units. (This figure represents the
number of units rated with a Power Consumption
Factor (PCF) of 1. For further information on the
PCF, please refer to chapter 9, Technical Data). The
unit can be installed at any convenient point in the
system cabling due to its built-in trunk-line
splitter. It is connected using loop-through
cabling. The unit switches on automatically when the
CCU is switched on. All outputs are protected
against short circuit. It can be used free-standing
on a table-top or mounted in a 19" rack. |

LBB 3508/00 Audio
Media Interface and Power Supply Unit
|
|
|
feature
Enables analogue equipment to be connected to the
DCN outputs
Powers up to 90 contribution units
Can be connected to the system at any point
Remote power on/off
|
|
The Audio Media Interface and Power Supply Unit
enables external analogue equipment such as
broadcast, recording and wired or wireless sound
distribution equipment to be connected to the DCN
system. This unit is equipped with four digital to
analogue converters and channel selection switches
for selecting the floor language or interpretation
channels.The LBB 3508/00 has a built-in power supply
which can drive up to 90 additional units. A
built-in trunk-line splitter enables it to be
connected to the trunk-line at any point, using
loop-through cabling. The unit switches on
automatically when the main CCU is switched on. It
can be used free-standing on a table-top or mounted
in a 19" rack |

LBB 3510/00 Network
Card for Personal Computer |
|
|
feature
Allows PC to communicate with DCN for application
software control functions
Headphone socket
Intercom handset socket
Optically-isolated inputs and outputs |
|
This network card enables an IBM-compatible PC to
communicate with the DCN system. It is installed in
the ISA-bus expansion slot at the back of the PC.
The DCN software modules can then be run on the PC.
The card also includes a headphone socket for audio
monitoring and an intercom handset socket for audio
communication. When connected to the DCN system its
input and outputs are optically isolated |
|
LBB 3511/00 PC Card
for Multi-CCU Systems |
|
|
This card provides the interface for communication
between the PC and interconnected Multi-CCUs, type
LBB 3500/30. It is installed in an 16-bit ISA-bus
expansion slot of a standard IBM?or compatible
personal computer.The PC Card should be installed in
a secondary dedicated PC, running OS/2, and not in
the main PC running the DCN control software in
Windows. Once the card and the Multi-CCU software
package LBB 3586 is installed, the PC acts as the
master net-work provider for all Multi-CCUs
connected to the multi-CCU network. A maximum of
eight Multi-CCUs can be connected to the card, in a
closed loop configuration, using the two BNC
connectors on the card. Standard 75 W (RG 59)
coaxial cable is used to make the connection. |

LBB 3512/00 Data
Distribution Board |
|
|
feature
Drives hall displays and camera systems
Allows transparent data transport for remote control
of external equipment |
|
This printed circuit board is used with digital
equipment such as hall displays, recorder systems
and camera controllers to provide the data
communication link to the DCN |
|
LBB 3559/05 Set of
100 Chip Cards |
|
|
These standard credit-card format chip cards are
used by delegates to identify themselves to the DCN
system. This can be a prerequisite for access to
contribution units and activities such as attendance
registration and voting. The cards have an
attractive design and ample space for a name or
other delegate personal information. The card
contains clear instructions showing how to insert
the card into a reader |

LBB 3557/00 Chip
Card Encoder |
|
|
Used in combination with the Chip Card Encoder
software module (LBB 3581), the LBB 3557/00 encodes
delegate chip cards (LBB 3559/00). |
