Important safety instructions

Danger due to high volumes

These devices are capable of producing sound pressure exceeding
85

dB(A). 85 dB(A) is the sound pressure corresponding to the maximum
permissible volume which is by law (in some countries) allowed to affect
your hearing for the duration of a working day. It is used as a basis
according to the specifications of industrial medicine. Higher volumes or
longer durations can damage your hearing. At higher volumes, the
duration must be shortened in order to prevent hearing damage. The
following are sure signs that you have been subjected to excessive noise
for too long a time:

• You can hear ringing or whistling sounds in your ears.

• You have the impression (even for a short time only) that you can no

longer hear high notes.

WiCOS – the wireless conference system

WiCOS – the wireless conference system

WiCOS stands for Wireless Conference System – the new generation of
mobile and wireless conference equipment from Sennheiser. The WiCOS
conference system utilizes all advantages of digital communications
technology:

• Ease of use due to automatic configuration of the system

• Easy installation and straight-forward operation

• Conference units with up to 20 hrs operating time

• Decentralized, clear sound reproduction

• Conference units are extremely easy to operate

• Voting function

• Dynamic frequency management for intermodulation-free operation

• 2 usable frequency bands (2.4 GHz and 5 GHz)

• Easy integration of the wireless WiCOS system into the wired SDC 8200
digital conference system from Sennheiser

• Ideal for both small seminars with only a few participants and large
conferences with any number of participants

Areas of application

The WiCOS conference system offers you reliable, wireless conferencing on
the 2.4 GHz or 5 GHz frequency bands. The system architecture allows for
different conference configurations:

WiCOS – the wireless conference system

Stand-alone operation – wireless conferencing

For stand-alone operation, you only require the WiCOS system
components. You can use different conference modes and, in addition to
running discussions, you can also conduct voting sessions.

The delegate and chairman units are wirelessly connected to the access
point, which acts as the central unit and controls the conference system.
The battery pack-powered conference units are wireless and can be placed
as you wish.

The access point has an integrated web server for configuring and
monitoring the WiCOS conference system. In order to control these
functions, a computer with network connection and a web browser is
needed.

Integrated operation (slave mode operation) – with the wired SDC 8200
conference and interpretation system

The WiCOS wireless conference system can be integrated into the wired
SDC 8200 conference and interpretation system. This allows you to expand
the conference system and/or easily bridge relatively long distances. In
slave mode operation, you can use the WiCOS system for simultaneous
interpretation and add professional accessories such as room
microphones, camera functions or the software control of the SDC 8200
conference and interpretation system.

For slave mode operation, you require the SDC 8200 conference and
interpretation system with the SDC 8200 CU-M or SDC 8200 CU central
unit. One or several access points can be connected to the central unit. As
in stand-alone operation, the access point controls the wireless
communication between the conference units. The conference system is
configured via the SDC 8200 CU-M or SDC 8200 CU central unit. In
integrated operation, all conference units of the wireless WiCOS system
behave like conference units of the SDC 8200 system.

To use language distribution, you also require SDC 8200 interpreter units.
The WiCOS DV and WiCOS CV conference units allow you to select between
up to 16 interpretation channels.

Setup for integrated operation

(slave mode operation)

The technology used

The radio technology of the WiCOS conference system is based on the
transmission standard for radio networks IEEE 802.11 a/g which is
widespread in computer technology. This radio standard offers the largest
possible operational reliability and transmission quality. The radio
protocols are optimized for conferencing, thus avoiding intermodulations
with existing radio networks. The dynamic frequency management of the
WiCOS conference system automatically detects occupied frequency
bands and changes to a free frequency band with no interruptions, even
during operation.

Configuring the conference system

• automatic frequency selection (dynamic frequency management;
recommended)

• manual frequency selection

The WiCOS conference system is factory preset to dynamic frequency
management. This function automatically detects occupied frequency
bands and switches to an unused frequency band, thus allowing for
interruption-free operation and parallel use of the WiCOS conference
system with other wireless conference systems, WLAN routers and other
radio networks.

The maximum number of access points you can use simultaneously varies
depending on the frequency range. If you want to use several conference
systems in parallel, we recommend careful frequency planning in order to
avoid mutual intermodulation between channels working in close
proximity.

왘 Have the system scan the available frequency ranges (see page 56).
왘 Set a fixed available frequency (see page 53).

radio signals of the conference system and the radio signals
of other devices can be subject to intermodulation.

왘 Make sure that the manually set frequency ranges are not

used by other devices and are not subject to
intermodulate (

see “Monitoring the frequency ranges –

“Quality“” on page 56).

왘 Use the dynamic frequency management.

To select an unused frequency range, use the frequency range monitoring
function which displays occupied and unused frequency ranges (see

Integrating WiCOS into a wired
conference system

You can integrate the WiCOS wireless conference system into the wired
SDC 8200 conference and interpretation system.

The advantages of integrated operation (slave mode operation) are as
follows:

• the wired SDC 8200 conference and interpretation system is easy to
expand using the conference units of the WiCOS series, which are
wireless and can be placed as you wish

• the WiCOS conference units are fully compatible with the SDC 8200 CU­M and SDC 8200 CU central units

• all conference modes and voting functions can be used (“yes”, “no”
and “abstain”)

• language distribution with up to 16 interpretation channels

In addition, you can integrate the WiCOS wireless conference system into
the wired Televic TCS
more information, refer to the instruction manual of the TCS

5500 conference and interpretation system. For

5500 system.

Set up for integrated operation

(slave mode operation)

Connecting the access point to the SDC 8200 CU central unit

To integrate the WiCOS conference system into the wired SDC 8200
conference and interpretation system, proceed as you would to connect a
conference unit to the SDC 8200 CU-M or SDC 8200 CU central unit. All
wireless conference units are recognized by the SDC 8200 CU-M or SDC
8200 CU central unit, just like wired ones are.

73

Integrating WiCOS into a wired conference system

For information on the configuration of your conference system, refer to
the instruction manual of the SDC
system.

You require system cables for slave mode operation of the WiCOS system.
The system cables are available in lengths of 2
and 50

The system cables are used:

• to connect the access point to the SDC 8200 CU-M or SDC 8200 CU

central unit or

• to interconnect several access points.

Several access points connected in series allow you to optimize the radio
coverage, for example in order to hold a conference in several rooms at the
same time.

The number of (wired and wireless) conference units is subject to the
following restrictions in integrated operation (slave mode operation):

Number of conference units SDC 8200 CU-M SDC 8200 CU

The access point is connected to the central unit.

In slave mode operation, the access point is powered via the central
unit and the system cable. However, you can also connect the DC
power supply. In this case, the power supply is automatically
switched off via the system cable.

74

왘 Establish the network connection to your access point in order to be

able to use the web server (see

page 48).

왘 On the web server, set the operating mode of the access point to “Slave

Mode” (see

page 61).
The conference system can now only be configured via the
SDC

8200 CU-M or SDC 8200 CU central unit (see page 77).

Integrating WiCOS into a wired conference system

Interconnecting several access points

Several interconnected access points are used:

• to operate small wireless conference systems in stand-alone operation
in several rooms in parallel and to interconnect these systems for slave
mode operation if required and

• to increase the radio coverage.

The length of the system cable between two access points must
not exceed 80

Initializing the conference units with the SDC 8200 CU central unit

In slave mode operation, you initialize all conference units (wired and
wireless) with the SDC
8200 conference and interpretation system.

Automatically initializing all conference units with the central unit

The automatic initialization allows you to initialize all conference units at
once. In this case, the conference units are assigned microphone numbers
automatically, in an arbitrary order.

왘 Switch on all wireless conference units that you want to use in your

conference system (see

Configuring the complete conference system - slave mode operation)

If the access point is in slave mode operation, you configure the conference
system including the wireless conference units optionally via the :

•SDC 8200 CU-M central unit

•SDC 8200 CU central unit

•SDC 8200 SYS-M PC control software

•SDC 8200 SYS PC control software

(see the instruction manual of the SDC 8200 conference and interpretation
system).

The web server of the access point offers you all setting and monitoring
options as before. However, only the following settings have an effect on
conference operation:

• In slave mode operation, you have to set the “Maximum number of

active microphones” for the wired conference units via the SDC 8200

CU-M or SDC 8200 CU central unit and for the wireless conference units
via the web server (see

page 57).

• In slave mode operation, the “Number of Interpretation channels” also
affects the maximum number of active microphones of the wireless
conference units (see

page 60).

• As a result of the different speaker limits of the central unit and the
access point, it is not possible to use the “FIFO” conference mode in
slave mode operation.

All other configurations can be changed, but in slave mode operation the
changes do not affect conferencing.

Using stand-alone operation in parallel with slave mode operation

Once you have connected one or several access points to the SDC 8200
conference and interpretation system, you can continue to use an access
point for stand-alone operation. For example, you can hold several
conferences in parallel, in different rooms for instance. The SDC 8200
conference and interpretation system allows you to link all conferences to
form one integrated conference.

To use stand-alone operation in parallel to slave mode operation:

왘 Set the operating mode of the access point to “Stand Alone” (see

page 61).
The WiCOS conference system functions completely independently of
the SDC

8200 conference and interpretation system.

Holding a conference in slave mode operation

Discussion mode

The conference mode is set via the SDC 8200 CU-M or SDC 8200 CU central
unit. (see the instruction manual of the SDC
interpretation system).

The conference units of the WiCOS conference system behave as they
would in stand-alone operation. For detailed information on the use of the
conference units, refer to

page 33 and page 36.

Carrying out voting sessions

In order to start a voting session, you require the WiCOS CV or SDC 8200 CV
chairman unit (see

page 38 and the instruction manual of the SDC 8200
conference and interpretation system). You can also conveniently plan,
manage and hold voting sessions via the SDC 8200 SYS-M or SDC 8200 SYS
PC control software.
