TS-800/900

Infrared Wireless Conference System

COOKBOOK

GENERAL DESCRIPTION

(1) Objectives

• With the aim of enhancing the lineup of the TS-700 Series currently on the
market, two series of conference system that employ the infrared
communication method are offered.

• Like the TS-700 Series, the new series target small-scale, temporary, or
committee meeting conference rooms. Designed to meeting the
requirements arising from recent merger wave among municipalities, they
are most suitable for new installation at city halls as well as tentative
installation needs to cope with a temporary increase in the number of
assemblymen at the time of the merger.

• The TS-800 Series represents a cordless version of the TS-700 Series.
Thus, its functions are almost identical with those of the TS-700.

• The TS-900 Series, a high-end model, is equipped with additional
functions such as a voting function.

General Description

(2) Wh y infrared comm unication method?

• The infrared communication method frees users from worries about
eavesdropping and radio interference inherent to radio wave-based
wireless communications.

• Place a single wall in between, and what is being discussed in the
conference room will never be heard outside. For the same reason,
it is possible to use two or more systems simultaneously in adjoining
conference rooms.

(3) Advantages of the cordless system

• Installation work is simplified. Wiring between the Central unit and the
Transmission/Receiver unit is all that's necessary. Wiring is easily done
with a single coaxial (BNC-BNC).

•A cordless system allows easy system installation and removal, greatly
reducing the workload associated with relocation and layout changes.

• Because no wiring to the conference units is necessary, the system is free
from troubles, such as deterioration and a break in the wiring, that are
caused by repeated installations and removals.

• The Transmitter/Receiver unit can be mounted on a microphone stand, to
create a tentative system without requiring installation work.

GENERAL DESCRIPTION

The number of the Chairman and Delegate units can be varied according to fit the

●

number of participants. (TS-800 Series: up to 64 units; TS-900 Series: up to 96 units)

Up to 16 Transmitter/Receiver units (when using TS-905 units only) and up to 12

●

TS-907 units (including instances where TS-905 and TS-907 are used in combination)
can be installed to create stable communication environment even in a large
conference room.

Designed for use in a high-ceilinged room, the TS-907 Transmitter/Receiver is capable

●

of communications in a room with ceiling height of more than 5 meters and less than 7
meters.

The Speaker Restriction function (1, 2, or 4) prevents confusion resulting from

●

simultaneous speeches by participants.

The speech system selection (first-in-first-out, last-in-first-out, or last-in-first-out after

●

2nd unit) enables the system to handle conferences in a wide range of situations.

The Chairman unit features a priority speech function. By talking while pressing the

●

priority speech key, the Chairman unit can override Delegate units.

Features

To prevent a howl, the monitor speaker of both Chairman and Delegation units is

●

turned off while the units are in use.

The Central unit can be used in combination with wired microphones or output source

●

equipment, depending on the purpose.

The 900 Series features a threefold vote function, which facilitates voting and counting

●

of "Yes," "No," and "Abstention" votes.

Both Chairman and Delegate units work either on the rechargeable lithium-ion battery

●

or AC current. With a fully charged battery, the unit operates for about 10 hours.
(assuming that the speech time amounts to one-third of the whole length of the
conference)

Dedicated microphones for Chairman and Delegate units are available in two types:

●

"standard" (primarily for use in a sitting position) and "long" (primarily for use in a
standing position).

Care should be taken to ensure the Chairman/Delegate Units are within the optimal
coverage area of the Infrared Transmitter/Receiver unit.

The Infrared Transmitter/Receiver unit must not be installed behind a user or any other
obstacle, as infrared signals will be unable to reach it. The Infrared Transmitter/Receiver units
must be installed to ensure that two or more units will always be in straight sightlines from
the Chairman/Delegate units.

If only one Infrared Transmitter/Receiver unit is used for communication, reception may be
interrupted if the infrared signals are blocked, either by an individual or obstacle. A minimum
of two Infrared Transmitter/Receiver units is required for an installation to enable the
Chairman/Delegate to always be able to communicate with them.

EQUIPMENT THAT AFFECT THE OPERATION

TS-800/900 SERIES

Equipment that affect the operation of the

Conference System units

Equipment that cannot be used in the same location as the System units.

• Plasma displays

Plasma displays emit a large amount of infrared radiation to illuminate the screen. For this reason, if
the Transmitter/Receiver unit is installed near a plasma display, or if terminals are used in front of the
plasma display, communication failure and noise may occur.

• Infrared LANs

• Infrared microphone systems

• Infrared simultaneous interpreting systems

As with the TOA Infrared Conference System, these systems also use infrared light. Thus, if used in
the same location, they could interfere with each other. In some cases, it may be the TOA system that
fails; in other cases, it may be the other system that becomes inoperable.

• etc.

Equipment that might cause unstable operation of the System units.

• Lighting equipment (spotlights and downlights)

When direct light from a spotlight or downlight reaches the infrared signal receiver of the
Transmitter/Receiver unit, communication failure or noise may occur.
Fluorescent lights have little effect on the Transmitter/Receiver unit’s performance. However, if light of
the incandescent lamp (downlight) is very intense, it could result in a slight decrease in the signal
traveling distance or a rise in noise floor. This problem can be avoided by increasing the number of
Transmitter/Receiver units installed.

• Sunlight

When direct sunlight hits the infrared signal receiver of the Transmitter/Receiver unit, communication
failure or noise may result. In general, this problem can be avoided by using (installing) the unit away
from windows or by covering windows with curtains or blinds.

6

CAUTIONS IN INSTALLING TS-800/900 SERIES

Cautions in installing the

Transmitter/Receiver unit

1. Install the Transmitter/Receiver unit away from windows.

Install the unit 2 – 3 meters away from the nearest
window, so that the effect of sunlight is minimized.

Sunlight

2 – 3 m

Note:

When effective coverage range is sought, installation will naturally be toward the center of the room.
Caution should be exercised when installing the unit close to the wall or near the corner of the room
to make it inconspicuous. If it is not possible to secure the above-mentioned distance, shading
sunlight with curtains or blinds will work.

2. IInstall the Transmitter/Receiver unit away from lighting equipment.

Lighting equipment may emit infrared portion of the light spectrum (especially incandescent lamps).
Installing the unit at least 50 cm away from lighting equipment minimizes the interference.

Ceiling

Fluorescent lights

50 cm or more

Note:

If the lighting equipment is mounted higher than (behind) the Transmitter/Receiver unit, there is no
need to worry (as in a case of the lighting equipment mounted flush with the ceiling).
If light does not directly hit the infrared signal receiver of the Transmitter/Receiver unit, there is no
need to worry. with curtains or blinds will work.

50 cm or more

3. Do not install the unit in pr oximity to the wall, column, and other obstacles.

Avoid installing the Transmitter/Receiver unit in close proximity to the wall, column or obstacles.
The unit could malfunction by detecting own infrared signals that are reflected.

Note:

A distance of 20-30 cm will be adequate to make the unit unaffected. However, caution should be
exercised when highly reflective materials such as a mirror are involved.
In particular, caution should be exercised when installing the unit in a large room with a column
in the center.

CAUTIONS IN INSTALLING TS-800/900 SERIES

Cautions in installing the

Transmitter/Receiver unit

4.Arrange the Transmitter/Receiver unit in such a way that individual conference units
can communicate with more than one Transmitter/Receiver unit.

As shown in a drawing, when a speaker in the front row talks while standing up, the infrared
reception could be interrupted. If the conference unit is made to communicate with two or more
Transmitter/Receiver units, such interruption won’t happen.

Note:

Enabling the conference unit to communicate with more than one Transmitter/Receiver units
greatly stabilizes operation. It also reduces the compandor noise that happens when the
conference unit is used at a location that is just barely within the coverage range.

-2

CAUTIONS IN INSTALLING TS-800/900 SERIES

Cautions in installing the conference unit

Make sure that the infrared signal receiver of the unit is not exposed to direct sunlight.

If direct sunlight hits the infrared signal receiver, the reception may be interrupted.

TRANSMITTER/RECEIVER UNIT

TS-800/900 SERIES

Transmitter/Receiver unit arrangement example

The maximum straight-line distance permissible for communication between the
Transmitter/Receiver unit and the conference unit is 7 meters.

Thus, the area range the Transmitter/Receiver unit
can cover varies depending on the height from
the conference unit to the ceiling. Arrange
Transmitter/Receiver units in such a way that the
units' coverage ranges overlap, so that all
conference units are included in the service area.

When the ceiling height is less than 7 meters, if the
units are arranged at intervals of 9 meters as
shown in the figure, a service area covering every
corner of the room can be secured.

*Choose the appropriate transmitter/receiver unit according to the

ceiling height.

Conference room using a round table

In a situation where all Chairman and Delegate
units are arranged on a round table and infrared
signals are not obstructed, a single
Transmitter/Receiver unit may completely cover
conference communications.
However, it is recommended that two or more
Transmitter/Receiver units be installed to prevent
communication interruptions.

Note:

In the case of a 30-by-30-meter room shown in the drawing, the units are arranged to provide more
than ample overlap of coverage areas. Arrangement like this, if it can be afforded, provides highly
stable communication environment. However, by arranging units to suit the usage (refer to
“Transmitter/Receiver unit arrangements according to the room size” below), it is possible to reduce the
number of Transmitter/Receiver units used.

TS-800/900 SERIES

Transmitter/Receiver unit arrangements

according to the seating style

When the same number of Transmitter/Receiver units is installed in rooms with the same size, the
arrangement of the units varies depending on the seat layout.
The drawings below represent ideal Transmitter/Receiver unit arrangements for roundtable seating and
parliamentary seating styles.

Arrangement for the roundtable seating style

In this case, placing the Transmitter/Receiver units
evenly inside the seating area enables all conference
units to communicate with both Transmitter/Receiver
units.

Arrangement for the parliamentary seating style

In this case, if the Transmitter/Receiver units are
arranged evenly, as is done for the roundtable
seating style, the Transmitter/Receiver unit at the rear
can communicate with only a smaller number of
conference units (because infrared signals from
conference units travel only in the forward direction).
For efficient utilization of the coverage area, it is
effective to place the Transmitter/Receiver units
toward the front of the conference units.

Wiring between the Transmitter/Receiver unit

and the Central unit

1. Note on wiring

When two or more Transmitter/Receiver units receive infrared signals from the conference unit,
the signal reception level increases if input signals to each Transmitter/Receiver unit are in phase.
If not in phase, the reception level may decrease. To avoid such a situation, the length of the
cables between the Central unit and each Transmitter/Receiver unit used in the same space
must be identical.

2. When a distributor is used

When using a distributor (YW-1022, YW-1024), do not connect more than two distributors in series.
Connecting three or more distributors increases high-frequency signal loss, and could result in
system malfunction.

It is possible to mix Transmitter/Receiver units that are not connected to any distributor, those

connected to 1 distributor, and those connected to 2 distributors in the same system.

1) Finding the maximum cable length using maximum allowable cable losses

Assuming that RG-59/U coaxial cable is used between the Distributor and the Infrared
Transmitter/Receiver unit, the cable loss between the two is calculated by the following equation:

Cable loss = 3.3 dB x (50 m / 100 m) = 1.65 dB

Since the Distributor's internal loss is 8.5 dB, the maximum allowable loss between the Central unit and the
Distributor becomes 9.85 dB (20 dB – 1.65 dB – 8.5 dB).

When RG-6/U coaxial cable is used between the Central unit and the Distributor, the length L1 between
the two is,

L1 = (Coaxial cable loss / its cable loss per 100 m )

= (9.85 dB / 2.7 dB) x 100 m
= 364 m

Maximum cable length L between the Central unit and the Infrared Transmitter/Receiver unit is
calculated by the following equation:

L= L1 + 50 m

= 364 m + 50 m
= 414 m

2) Finding the maximum cable length using voltage drop

The current flowing from the Distributor into each coaxial cable connected to the TS-905 Infrared
Transmitter/Receiver unit is 0.1 A, since the number of Infrared Transmitter/Receiver units connected to
each coaxial cable is 1.

Assuming that RG-59/U coaxial cable is used, the voltage drop between the Distributor and the Infrared
Transmitter/Receiver unit is calculated by the following equation:

Voltage drop = 16.82 Ω x (50 m / 100 m) x 0.1 A

= 0.841 V

A remaining voltage of 4.159 V (5 V – 0.841 V) is the maximum allowable voltage drop between the
Central unit and the Distributor. The current that flows between the two is 0.4 A.

When RG-6/U coaxial cable is used between the Central unit and the Distributor, the cable length L1
between the two is,

L1 = { (Voltage drop 1 / Current 1) / Coaxial cable loop resistance 1 per 100 m }

= { (4.159 V / 0.4 A) / 12.82 Ω } x 100 m
= 81 m

Maximum cable length L between the Central unit and the Infrared Transmitter/Receiver unit is
calculated by the following equation:

L= L1 + 50 m

= 81 m + 50 m
= 131 m

Similarly calculated for other types of coaxial cables, the maximum cable length between the Central unit
and the Infrared Transmitter/Receiver unit is found in the following table.

TS-905

Because of the 2 serially-connected 4-branch distributors, their loss is 17 dB (8.5 dB + 8.5 dB), which is
added to the above cable loss, causing a total loss of 18.92 dB (1.65 dB + 0.27 dB + 17 dB). Therefore, the
maximum allowable cable loss between the Central unit and the Distributor 1 is calculated to be 1.08 dB
(20 dB – 18.92 dB).

• Assuming that RG-11/U coaxial cable is used, L1 between the Central unit and the Distributor 1 is
calculated by the following equation:

L1 = (Coaxial cable loss / its cable loss per 100 m)

= (1.08 dB / 2 dB) x 100 m
= 54 m

Maximum cable length L (Length between the Central unit and the Infrared Transmitter/Receiver unit)
= 54 m + 10 m + 50 m = 114 m

• Assuming that RG-6/U coaxial cable is used, L1 between the Central unit and the Distributor 1 is
calculated by the following equation:

L1 = (Coaxial cable loss / its cable loss per 100 m)

= (1.08 dB / 2.7 dB) x 100 m

= 40 m
Maximum cable length L (Length between the Central unit and the Infrared Transmitter/Receiver unit)
= 40 m + 10 m + 50 m = 100 m

Similarly calculated for other types of coaxial cables, the maximum cable
length between the Central unit and the Infrared Transmitter/Receiver unit
is found in the table.

2) Finding the maximum cable length using voltage drop

The current flowing from the Distributor 2 into each coaxial cable connected to an Infrared
Transmitter/Receiver unit is 0.1 A, since the number of Infrared Transmitter/Receiver units connected to
each coaxial cable is 1.

Assuming that RG-59/U coaxial cable is used, the voltage drop between the Distributor 2 and the Infrared
Transmitter/Receiver unit is calculated by the following equation:

Voltage drop = 16.82 Ω x (50 m / 100 m) x 0.1 A

= 0.841 V

When RG-6/U type coaxial cable is used, since the current flowing into each coaxial cable between
Distributor 1 and Distributor 2 is 0.4 A, the voltage drop between the two is calculated by the following
equation:

Voltage drop 2 = 12.82 Ω x (10 m / 100 m) x 0.4 A

= 0.513 V

Voltage drop 1 + Voltage drop 2 = 1.354 V

A remaining voltage of 3.646 V (5 V – 1.354 V) is the maximum allowable voltage drop between the
Central unit and the Distributor 1. The current that flows between the two is 1.6 A.

• Assuming that RG-11/U coaxial cable is used, L1 between the Central unit and the Distributor 1 is
calculated by the following equation:

L1 = { (Voltage drop 1 / Current 1) / Coaxial cable loop resistance 1 per 100 m }

= { (3.646 V / 1.6 A) / 2.4 Ω } x 100 m
= 94 m

Maxim cable length L (Length between the Central unit and the Infrared Transmitter/Receiver unit)
= 94 m + 10 m + 50 m = 154 m

• Assuming that RG-6/U coaxial cable is used, L1 between the Central unit and the Distributor 1 is
calculated by the following equation:

L1 = { (Voltage drop 1 / Current 1) / Coaxial cable loop resistance 1 per 100 m }

= { (3.646 V / 1.6 A) / 12.82 Ω } x 100 m
= 17 m

Maxim cable length L (Length between the Central unit and the Infrared Transmitter/Receiver unit)
= 17 m + 10 m + 50 m = 77 m

Similarly calculated for other types of coaxial cables, the maximum cable length between the Central unit
and the Infrared Transmitter/Receiver unit is found in the following table.

Notes on installation (summary)

Notes on installation (summary)

• The coverage area of infrared communication varies depending on the type of the

Transmitter/Receiver unit used and ceiling height. (see page 5-1)

• The TS-905 works for ceiling heights of more than 2.5 meters and less than 5 meters,

while the TS-907 works for heights of between 5.0 meters and 7.0 meters. In view of the
Transmitter/Receiver unit’s performance capability, infrared communication becomes difficult
if the ceiling height exceeds 7 meters.

• In mounting the Transmitter/Receiver unit, consideration should be given to the direction

in which infrared signals from the conference unit travel.

• Do not install the Infrared Conference System in the same space where a plasma display or

an infrared LAN system is in use.

• Be careful of downlights and spotlights that give off a large amount of light.

• Install the Transmitter/Receiver unit away from windows, lighting equipment, and obstacles.

• The effect of sunlight can be avoided by the use of curtains or blinds.

• Use appropriate numbers and arrangement of Transmitter/Receiver units, so that the

conference unit can communicate with two ore more Transmitter/Receiver units.

• The more Transmitter/Receiver units are used, the more stabilized communications the System

can provide.

• Be sure to make all cables between the Central unit and the Transmitter/Receiver unit identical

in length.

• When a distributor is used, make the length of all cables coming out from the distributor

identical. This minimizes unnecessary wiring.

• After wiring design is completed, the cable loss and voltage drop must be calculated.
