Modular system structure
Any kind of configuration can be set up just by
daisy-chaining HCS-4800 congress units. The modular
system structure of HCS-4800 is applicable to any kind
of conference and provides an accurate and efficient
solution. Additional congress units can be added when
needed. More system functions are available in
connection with a PC and control software.

Dual congress main unit hot spare
HCS-4800 dual main unit hot spare is a disaster
protective structure. Besides the main unit, the user
can set another CMU as backup CMU and connect it to
the system. If the main unit breaks down during the
conference, the backup main unit substitutes the main
unit and the system software will connect to backup
CMU automatically, ensuring the consistency of the
conference.

HCS-4800 system software infrastructure
HCS-4800 system software is designed for the
prevalent Client/Server structure. Client and server
communicate with each other by using TCP/IP network
protocol, ensuring both data security and transmission
efficiency. Client and server software can run on the
same computer as well as on different computers in the
same LAN, enabling the operator to manage the
conference more flexibly.
HCS-4800 system software imports the hot-spare dual
server structure by using a main server and a back-up
server. While the main server is processing, data are
stored real time on the back-up server to prevent
conference related information from loss in case of a
crash of the main server. As a result, security and
reliability of the conference system are improved vitally.

Duplicate and backup connection via “Closed
Loop - Daisy Chain” connection
For important meetings, especially those which
consider connection reliability as their leading point,
HCS-4800 Series Fully Digital Congress System
adopts advanced "Closed Loop - Daisy Chain"
connection topology, connecting the last unit in the loop
back to the congress main unit. Therefore, any
congress unit in the loop has two connection paths to
the congress main unit. As a result, breakdown or
replacement of a congress unit and connection failure
of a cable will not influence other congress units. As
such the system features the advantages of a
daisy-chain connection system with its simplicity of
cabling as well as the improvement of the system
reliability through duplicate and backup connection
functions.

Advanced TCP/IP communication protocol in
PC control
In a PC controlled system, the congress main unit and
the PC use the advanced TCP/IP protocol.
Theoretically, the communication distance between the
PC and the CMU can be infinite. This is decisively
different to traditional RS232 connection modes where
the distance between the PC and the CMU cannot
exceed 15 meters. TCP/IP enables remote control,
remote diagnosis and remote update.
By using network techniques, conference systems are
tightly linked to the rapidly developing internet
technology, computer science and communication
technology. Users enjoy the convenience of the
contemporary leading techniques, e.g. by using the
compatible wireless LAN techniques (802.11) - such as
PDAs - which can be used to control a conference
system wirelessly. The import of network topology also
