2. GENERAL DESCRIPTION
The TOA TS-910 Series conference system permits both its infrared wireless system unit and wired system unit
via CAT-5 LAN cable connections to be used in combination.
The wired Chairman and Delegate units (collectively referred to as “Conference units”) are connected to the
Central unit via the wired Expansion unit and Bridge unit.
The Infrared Conference units provide wireless communication via the Infrared Transmitter/Receiver unit
connected to the Central unit. Since wiring to the individual Conference units is not required, they can be easily
installed in freely versatile configurations.
A total of up to 192 Infrared and Wired Conference units can be connected to the Central unit of each system.
The Infrared Transmitter/Receiver unit is required for connection of the Infrared Conference units. (Refer to
p. 27.)
The Expansion unit and Bridge unit are necessary for connection of the Wired Conference units. (Refer to
p. 39.)
The Central unit is used to perform system function settings, status display, etc.

6.1. Notes on Installation of the Infrared Transmitter/Receiver Unit
Installing the Infrared Transmitter/Receiver unit in locations exposed to sunlight or in proximity to such infrared
sources as fluorescent lights could result in system failures or the introduction of noise into the system. Avoid
installing the Infrared Transmitter/Receiver unit in close proximity to infrared sources, as instructed below:
[Avoid direct sunlight]
• Cover windows with curtains or blinds to shield
the unit from direct exposure to sunlight.
• Install the unit at lease 2 – 3 meters away from
the nearest window.

• Infrared signals cannot reach the Infrared Transmitter/Receiver unit if it is hidden behind the user or other
objects. Install multiple Transmitter/Receiver units in line-of-sight from all Conference units.
• Install the Infrared Transmitter/Receiver units in such a way that each Conference unit can always communicate
with two or more Transmitter/Receiver units. If installed in such a way that communication is only established
with one Transmitter/Receiver unit, the infrared signal may be blocked by persons or other objects, possibly
causing a momentary loss of signal reception.

Central unit
When two or more Infrared Transmitter/Receiver units receive infrared signals from the Infrared Conference
units, the signal reception level increases if input signals to each Transmitter/Receiver unit are in phase. If not
in phase, the signal reception level may decrease.
• To put signals in phase, ensure that the following cable length between two components are identical.
Length between each Infrared Transmitter/Receiver unit and the Central unit: L + M0 + N0 = M1 + N0 = N1
Note: This length must always be the same even if a distributor is included in the wiring.
Length between Infrared Transmitter/Receiver unit and distributor: L
Length between distributors (where two distributors are connected): M0
Length between distributor and Central unit:
N0
(In the above figure, since there is only one N0 connection, the length need not be matched for the N0 line.)
• The maximum cable length between each Infrared Transmitter/Receiver unit and the Central unit differs
depending on the type of coaxial cable to be used. (Refer to p. 54.)
Take care not to exceed the maximum cable length.
6.4.2. Using the Distributor
• The YW-1022 is a 2-branch distributor, and the YW-1024 is a 4-branch distributor. In the case of the YW1024, its distribution terminals may become idle depending on the Infrared Transmitter/Receiver unit's wiring.
However, this presents no problem.
• Avoid connecting more than 2 distributors in series. Connecting 3 or more distributors increases highfrequency signal loss, and could result in system malfunction.
• It is possible to mix Infrared Transmitter/Receiver units not connected to any distributor, those connected to
1 distributor, and those connected to 2 distributors in the same system.
• To avoid an increase in loss, do not perform connections between distribution terminals.

When installing in the same space,
• All "L" cables must be identical in length
• All "M" cables must be identical in length.
Note
To facilitate the unification of coaxial cables used in
different connections into the same length, it is highly
recommended that wiring from the Central unit to the
distributor mounted in a ceiling be performed with
a single cable. For other ceiling wiring, using pre-cut
coaxial cables of a slightly longer length will facilitate
making all connections the same length.

not be matched to the same length.
• All L0 cables are the same length.
• All L1 cables are the same length.
• All M0 cables are the same length.
• L0 and L1 cables need not be the same, since they
are used in different rooms.
• M0 and M1 cables need not be the same length,
since they are used in different rooms.
Note
The above condition also applies to cases in which two
conference systems, both including the Conference
units, are apart from each other in the same room so
that communications cannot be made between the two
systems.

Step 1. Make a 68 mm diameter hole in the ceiling.
Step 2. Attach the supplied mounting plate to the ceiling panel.
Notes
• Since the distance between two mounting screw holes is 83.5 mm, the plate can also be mounted
over an electrical box.
• For open wiring, use of an electrical box is recommended.
• When attaching the plate to an electrical box, use an L-shaped BNC plug or L-shaped conversion
connector.
Step 3. After wiring completion, mount the Infrared Transmitter/Receiver unit to the mounting plate.
With the unit's tabs (3 places) aligned with each corresponding notch in the mounting plate, rotate the
Infrared Transmitter/Receiver unit clockwise till it stops and fits into place.

Notes
• It is recommended that the RG-59/U, RG-6/U, or RG-11/U coaxial cable be used.
• Since the Infrared Transmitter/Receiver unit is equipped with the Live Status indicator, it is possible to confirm
whether or not the coaxial cable is correctly connected. (The indicator cannot be used for confirmation of the
unit's minimum operating voltage.)
When the indicator does not light, it can be considered that the coaxial cable is not connected or shorted.
• The Central unit has a Short Circuit indicator on its rear panel and the Central unit's short circuit protection
circuit is common to all 4 BNC terminals. If this short circuit indicator lights, locate the shorted point by
removing each distributed cord. The indicator also lights when the number of Infrared Transmitter/Receiver
units connected in the system exceeds the allowable limit.

14. Appendix (Infrared Transmitter/Receiver Connection)
This chapter describes how to find the maximum cable length between the Central unit and the Infrared
Transmitter/Receiver unit.
Values calculated here are given only as guidelines, since they can vary depending on ambient building
conditions and the Infrared Transmitter/Receiver unit.
14.1. Wiring Design
14.1.1. Confirming the wiring design

calculate the cable length on the following each condition. The shorter length of the two results is the required
extendable length.

1) Finding the maximum cable length using maximum allowable cable losses
Assuming that the type of coaxial cable used is RG-59/U,
Maximum cable length L = (Coaxial cable loss / its cable loss per 100 m )
= (20 dB / 3.3 dB) x 100 m
= 606 m
The following table shows the maximum allowable cable length for each type of coaxial cable.

2) Finding the maximum cable length using voltage drop
Since one TS-905 Infrared Transmitter/Receiver unit is connected per coaxial cable, the current that flows
through each coaxial cable is 0.1 A.
Assuming that the type of coaxial cable used is RG-59/U,
Maximum length L = { (Voltage drop 1 / Current 1) / Coaxial cable loop resistance 1 for 100 m }
= { (5 V / 0.1 A) / 16.82 Ω } x 100 m
= 297 m

Condition: Cable length between the Distributor and the TS-905 Infrared Transmitter/Receiver unit is assumed
to be 50 meters.

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
aximum cable length L between the Central unit and the Infrared Transmitter/Receiver unit is calculated
M
by the following equation:
L
= L1 + 50 m
= 364 m + 50 m
= 414 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.
RG-59/U
348 m
RG-11/U

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
aximum cable length L between the Central unit and the Infrared Transmitter/Receiver unit is calculated
M
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.

1) Finding the maximum length using maximum allowable cable losses
Assuming that RG-59/U coaxial cable is used, the cable loss between the Distributor 2 and the Infrared
Transmitter/Receiver unit is calculated by the following equation:
Cable loss = 3.3 dB x (50 m / 100 m) = 1.65 dB
Assuming that RG-6/U coaxial cable is used, the cable loss between the Distributor 1 and Distributor 2 is
calculated by the following equation:
Cable loss = 2.7 dB x (10 m / 100 m) = 0.27 dB
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 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 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.
