System placement

Installing the CU(s) in a rack

Rack requirements for the CU

• EIA standard compatible 19-inch rack

• 1U-size rack mounting

• Rack equipped with safety guardrails to support the CU and a

board on which the CU is to be placed

When installing the CU(s) in a rack, keep the temperature within the rack below 45°C (113°F). High temperature may damage the internal components, causing a malfunction. Leave a space of 10cm or more on each side (top, right and left, rear) between the CU and other devices or the rack.

Rack mounting angles are fixed to the CU using the following screws. When using screws other than those listed here, check the specifications.

• S TIGHT tapping screws with nominal diameter 4×6mm*

* Substitutable for M4×6mm machine screws

Unbalanced connection

Since induction noises tend to occur due to difference in electric potential of chassis:

• Keep the chassis between each device at the same electric

potential.

• Use the same power system.

• Connect to the GND (ground) terminal or chassis ground of each

device.

AC power cord connection

Be sure to connect the AC power cord into a properly grounded wall outlet. Improper grounding can cause electrical shock.

When cleaning the units

Do not use any solvents or chemicals such as benzine, thinner, alcohol or electrical contact cleaner and protector. Doing so may cause deformation, damage and malfunction of the units.

Overview of the Interpretation Unit

"Hello"

"Thank you"

" こんにちは "

" ありがとう "

(ATUC-50INT)

• Up to 6 interpretation units can be connected.

• The maximum number of DU/IU/INT connections is 300 (when three CUs are linked).

• INTs can only be connected to the primary CU. They cannot be connected to extension CUs.

Digital Conference System ATUC-50 with the additional Interpretation Unit ATUC-50INT enables the following three types, (1) to (3), of interpretation. This section explains a brief overview of operations assuming that you have set the interpretation languages as in the following table.

Audio Group 1 English

Language Name

Audio Group 2 Japanese

Audio Group 3 French

(1) Interpretation using two languages (2 Languages)

• While in the 2 Languages interpretation mode, you can select from three interpretation patterns (see table below).

• For instance, when the interpretation pattern “English → Japanese” is set, “F” appears as the character on the left in the display ①, and “2” appears as the digit on the right. At this time, the speech from the floor channel is heard through the monitor channel. Additionally, interpreted speech that is input from the microphone of the INT is output to Audio Group 2 (the Japanese group).

• When the bi-directional interpretation pattern is selected, the interpretation system is established with just this INT1. Pressing the interpretation languages selection button ⑥ switches the interpretation patterns between “Japanese → English (Outgoing language A)” and “English → Japanese (Outgoing language B)”, simultaneously switch the interpreted speech being output. Whichever interpretation pattern you selected, “Japanese → English (Outgoing language A)” or “English → Japanese (Outgoing language B)”, it is not saved. When the system is started, the interpretation pattern is “Japanese → English (Outgoing language A)”.

• Out of the three languages, the language of Audio Group 1 is used as the key language (in this case it is English), and relay interpretation is possible. (diagram below)

• When interpreting from French to Japanese, for example, Interpreter C first interprets “French → English”. Interpreter B switches the monitor channel to the key language “1”, listens to the English interpretation from interpreter C, and then interprets “English → Japanese”.

• Other than that, the basic operations are the same as those for 2 languages.

• Remove the DU/INT bottom cover to connect the Ethernet cables. When removing the bottom cover, pinch together the latches on both sides.

• On the DU/INT, the Ethernet cable may be connected to the left or right DU/CU connection terminal because the DU/INT does not distinguish between DU and CU connection terminals.

Connecting the DUs/INTs together

Ring connection:

Connect as many DUs/INTs as necessary to each of the DU CHAIN A/B terminals and then connect together the 2 DUs/ INTs on both ends of the chain so as to form a ring. Even if a connection failure occurs somewhere in the ring, since the connection is recognized as 2 daisy-chains using the DU CHAIN A/B terminals, the influence of the failure can be minimized and you can carry on conference control.

To ATUC-50CU

Ethernet cable

Connect the DUs/INTs according to the

Ethernet cable

installation environment and operation method.

Daisy-chain connection:

Connect the DUs/INTs in a series to the DU CHAIN A/B (C/ D) terminals. Compared to ring connection, daisy-chain connection enables the DUs/INTs to be placed even farther from the CU.

One more ring connection can be made by configuring these terminals as the DU CHAIN terminals.

Even if a connection failure occurs, since the connection is recognized as 2 daisy-chains using the DU CHAIN A/B terminals, you can carry on conference control.

• Combining different connection types is also possible, such as a ring connection using the DU CHAIN A/B terminals and daisy-chain connections using the DU CHAIN C/D terminals.

End of the chain

If a connection failure occurs here, the connection to the end of the chain will be defunct.

Expand the system with EXT.

By adding EXT to the system, you can increase the number of DU/ INT/IU connections and extend the distance of the total extension length of the connecting cable (LAN cable). For instance, you can connect a total of 100 DUs/INTs/IUs, 50 units on either terminal, by connecting an EXT near the B terminal when using a daisy chain connection on the DU CHAIN A/B terminals.
