Example 4 - conference with PC control
The venue and number of participants is similar to exam-
ple 3, but extra facilities are provided by the addition of a
PC (with DCN application software modules), a wireless
language distribution system and an alphanumeric display
for showing voting results. The LBB 3500/15 Extended
CCU carries out core control functions, and this is comple-
mented by the conference management facilities available
to the operator via the appropriate application software.
The use of the PC and the relevant software modules
allows electronic identification and access control for
contributing delegates, via a card reader with or without
PIN code. All contributing delegates use the
LBB 3546/00 Delegate Unit, which incorporates a Chip-
Card reader facility. The chip-cards are encoded using
the Chip-Card Encoder software module and the
LBB 3557 Chip-Card Encoder.
An infra-red transmission system is used to distribute
the interpretation languages to the seated non-con-
tributing delegates. The Infra-Red Transmitter and
strategically-located infra-red radiators are used to dis-
tribute the available languages throughout the confer-
ence venue. Each non-contributing delegate is equipped
with an infra-red receiver and headphones, and can
