Modular system structure
Any kind of configuration can be set up just by
daisy-chaining HCS-4100/50 fully digital congress units.
The modular system structure of HCS-4100/50 is
applicable to any kind of congress 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-4100/50 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-4100/50 system software infrastructure
HCS-4100/50 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
congress more flexibly.
HCS-4100/50 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 congress related information from loss in case
of a crash of the main server. As a result, security and
reliability of the congress 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-4100/50 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 simpleness of
cabling as well as the improvement of the system
reliability through duplicate and backup connection
functions. In HCS-4100/50 series system, the congress
main unit can realize a “Closed Loop - Daisy Chain”
connection, but only one – extension units do not offer
this feature.

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 RS-232 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, congress 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
