Chapter 3: SYSTEM SETTINGS (NX-100 SETUP PROGRAM)
1. GENERAL DESCRIPTION
1.1. What is the NX-100 Setup Program?
This program is used to set all the NX-100 and NX-100S units connected to a LAN. It also provides a simple
display on the PC screen of operating data for multiple NX-100 and NX-100S units connected to a LAN.
Its main features are as follows:
• Scans and displays all NX-100 and NX-100S units connected to a LAN.
• Automatically sets IP addresses without duplication. Permits manual changes as well.
• Permits simultaneous uploading of setting files to two or more NX-100 and NX-100S units.
• Backs up setting files for two or more NX-100 and NX-100S units in a batch.
• Easily and efficiently performs broadcast settings between units.
Note
When setting the unit connected to the Internet, refer to Chapter 4, System Settings (Setting Using Browser).
1.2. About Network Settings
Follow the instructions of the network management personnel before performing network settings for the PC
and connected units. Incorrect settings may adversely influence other units connected to the same network.
1.3. Backing-Up Setting Files
Setting contents, once saved, are saved in the data folder located inside the Setup program's installation
folder (Default path: C:\Program Files\TOA\NX-100) as a unit setting file. If uploaded, these files are stored in
each NX-100 and NX-100S as unit setting files. It is highly recommended that all settings be backed up.
Backing up settings to other locations on the PC hard drive or to external storage devices facilitates
restoration should the NX-100, NX-100S or PC inadvertently fail. To save backup copies, copy the entire data
folder located in the Setup program's installation folder.
Caution
When settings are changed, be sure to update the backup files as well.
1.4. Cautions Concerning Setting Updates
Never restart the NX-100 and NX-100S units nor turn off their power supply while updating* the setting
contents.
* The Status indicator on the unit's front panel flashes during an update.

connected units on-site.
(1) System Setting
Using the System Setting Tool, program all the units in the system, and enter their unit names and IP
address numbers.
• System:
Set audio I/O unit names.
Set the port number.
• Network:
• Broadcast Spec:
Perform Broadcast Spec settings based on the network configuration.
Before using this function, confirm the following information with network
management personnel:
· Usable bandwidth
· Whether or not multicast streaming can be used
• Broadcast Pattern: Set the units to be connected in each broadcast pattern when activated by
contact or the Operation program. (This setting not needed for units that will not
be used in broadcast patterns.)
• Contact:
Set the broadcast pattern to be activated when a contact is received, and the
contact output for other connected units. Also, set the operation to be
performed when contact output is activated by other units.
NX-100 only
• Serial Bridge
: Set the units to be connected and their serial ports when using the
serial bridge function.
(2) Saving Data Files
Save the data folder located in the Setup program's installation folder to the PC's hard disk drive or a
connected external storage device. Also be sure to save backup copies.
(3) Unit Scanning (Network Setting)
• After installing the system's Setup program on-site, copy the contents of the data folder saved in
Step (2) above to the data folder.
• After setting the network using the Unit Scanning Tool, upload the unit setting file using the System
Setting Tool.
Important
When performing settings according to this procedure, the pre-programmed set system setting contents are
erased if [Save in setting file format] is executed using the Unit Scanning Tool. To prevent this, take the
following precautions:
1. After completing settings using the System Setting Tool, copy and save the data folder under a
different name.
If a data folder copy is saved, even when [Save in setting file format] is selected, it is possible to write the
unit setting file into the NX-100 and NX-100S after recopying the previously saved and renamed folder to
the data folder.
2. After performing settings using the Unit Scanning Tool, use the System Setting Tool only after
uploading the settings, but without executing [Save in setting file format].
This prevents the unit setting file in the data folder from being overwritten.

Exit:
Exits the program.
Important
The [Save in setting file format] function is used to set broadcasts in the system settings after the unit scan is
complete. Selecting [Save in setting file format] writes the setting contents into the data folder. The contents of
the unit setting file include only the IP address, subnet mask, default gateway, unit name, and Web server port
number.
When broadcast contents have previously been set and saved using the System Setting Tool, these earlier
system settings will be erased if [Save in setting file format] is selected.
If system setting has already been performed, take the following measures to prevent erasure of the setting
contents:
1. Upon completion of System Setting Tool settings, copy and save the data folder under a different
name.
If the data folder is copied, the unit setting file can be written into the NX-100 and the NX-100S after
copying the renamed folder to the data folder, even when [Save in setting file format] is selected.
2. After Unit Scanning Tool settings have been performed, use the System Setting Tool after
uploading the settings, but without executing [Save in setting file format].
This prevents the unit setting file in the data folder from being overwritten.

Chapter 4: SYSTEM SETTINGS (SETTING USING BROWSER)
(2) Information
Indicates the delay time, bandwidth, and whether or not broadcasts are possible when broadcasts are
made using values selected in the Broadcast Spec settings.
[Delay]
The delay time is the duration until an audio signal received at the NX-100 and NX-100S passes through
the network and is broadcast by other connected NX-100 and NX-100S units.
[Bandwidth]
Indicates the bandwidth for voice streaming over the network. The bandwidth used is indicated in red if the
setting exceeds the usable bandwidth set in the Navigator section.
[Broadcasts possible with this spec]
Broadcasts that are possible with the set Spec are marked with "OK", and those that are not possible are
marked with "NG." The conditions under which broadcasts can be made are as follows:
Transmission only (broadcasts from the original unit to other units):
Broadcast signals can be sent to a connected unit if the transmission bandwidth is within the set
bandwidth.
Reception only (broadcasts from other units to the original unit):
Broadcast signals can be received from a connected unit if the reception bandwidth is within the set
bandwidth.
Local broadcast (transmissions from the original unit's audio input to its audio output):
Local broadcasts cannot be made if the transmission sampling frequency is set to 32 kHz.
Multiple unicast streaming and Two-way:
Cannot be performed when packet transmission intervals are short. Adjust the sampling frequency,
compression, packet size, packet loss recovery and its level.
(3) Audio Setting
[Sampling Frequency]
Select the transmission and reception sampling frequencies from [8], [16], and [32] kHz. Sound quality
improves with higher sampling frequencies, however this makes the bandwidth wider.
[Compression]
Select [Yes] or [No]. To narrow the bandwidth of the network, it is highly recommended that compression
be enabled.

and [Resend]. Refer to p. 6-4 for details of each recovery method.
In case [Error correction] is selected, the correction level can be changed, allowing selection from [1
(Low)], [2], [3], and [4 (High)]. Higher settings increase correction capability, however delay times are also
made longer.
In case [Resend] is selected, delay times can be entered for 5 – 30 seconds. Longer delay times increase
correction capability. Note that [Resend] cannot be selected if [Compression] is set to "No."
[Multicast]
The multicast address must be set when sending multicast streaming. Selecting "Yes" for Multicast allows
the multicast address to be entered. The effective address range is from (225.0.0.0) to (238.255.255.255).
Perform this setting while taking care that the same number is not duplicated among the units connected
to the same network.
Note
Be sure to consult with network management personnel before performing this setting.
(5) Sampling Frequency Correction

5. SETTING PROCEDURES USING THE OPERATION PROGRAM
Before performing the setting using the Operation program
Set the NX-100 and NX-100S units in the system using the NX-100 Setup program.
Broadcast settings that will be activated by the operation program must all be programmed into each
connected unit as the "broadcast pattern."
The NX-100 Setup program cannot be used to set NX-100 and NX-100S units connected
via the Internet.
If the system contains NX-100 and NX-100S
units not set with the Setup program such as
the units connected through the Internet.
If only NX-100 and NX-100S units
set with program are used.
(1) Add the unit to the system.
NX-100 and NX-100S units set with the Setup program as system units are automatically
recognized as operable units by the NX-100 Operation program. NX-100 and NX-100S
units which were set without using the NX-100 Setup program, such as the units
connected through the Internet, can be added to the system setting using the NX-100
Operation program.
(2) Set the Button layaout.
Edit the Button layout.
Edit the layout of the Selection and Group buttons on the operation screen.
(3) Set the Selection buttons.
Set the Selection buttons that select the broadcast patterns or contact outputs to be activated.
Use the broadcast patterns which were programmed into the operable units (those units set with the
NX-100 Setup program and added in Step (1) above).
Only one pattern can be programmed into each Selection button.
When simultaneously activating two or more broadcast patterns with the Group button, all of the
broadcast patterns to be activated must first be programmed into the Selection buttons.
If simultaneously activating multiple
broadcast patterns
(4) Set the Group buttons.
Use the Group button when wishing to simultaneously activate two or more broadcast patterns. Select

1. EXPLANATION
1.1. IP Network and Address
The IP networks the NX-100 and NX-100S can use include Local Area Networks (LAN) used in small-scale
areas, such as within or on the premises of a company, and the Internet, which covers a wide area over
remote distances.
Router

NX-100/100S
(C)
NX-100/100S

NX-100/100S
(B)
LAN
LANs differ from the Internet in the IP address to be used.
Local IP address (private IP address): This address is used and can be freely set within the LAN.
Global IP address:
This is the only address that is used to access the Internet.
To use the NX-100 and NX-100S units through the Internet, fixed
global IP addresses must be acquired and assigned to them or the
router if it is used.
When a connection is made from Unit B to Unit A in the figure, the local address can be used. However, when
a connection is made from Unit C to Unit A, the global IP address must be used.
The fixed global IP address must be assigned to the units connected via the Internet.
When selecting an NX-100 or NX-100S which is connected through the Internet as the "target connection unit"
for a broadcast pattern, contact or serial bridge* in NX-100 or NX-100S unit setting, the fixed global IP
address must be designated.
Consult with network management personnel or the ISP (Internet service provider) concerning the acquisition
of a fixed global IP address.
* The serial bridge function is valid only for the NX-100.

Chapter 6: APPENDIX
1.2. Network Address Translation (NAT) and Setup Software Programs
Because the Internet cannot be accessed using the local IP address, the local IP address must be converted
into the global IP address by means of Network Address Translation (NAT).

LAN
Connections can be made from Unit C to Unit A using the global IP address. The global IP address used for
the connection is converted into the local address for Unit A by Router 1.
Note that the NX-100 Setup program is not designed to enable the NAT function. Use a browser to select
units connected by way of the NAT as the target connection unit for the broadcast pattern, contact or serial
bridge* in the NX-100 and NX-100S unit settings.
* The serial bridge function is valid only for the NX-100.
1.3. IP Broadcast and Unit Scan
The IP broadcast communication method is used to scan the units connected to the network. Units can only
be scanned within the effective range of the IP broadcast.
The address to be used is 255.255.255.255.

PC
IP broadcast does not reach beyond the router covering range even in the LAN.
In the above figure, NET1 represents the LAN and NET2 represents the effective range for IP broadcast. For
example, if the PC is used to scan the units in the figure, Unit C cannot be scanned even though it is located
within the same LAN.
Note
Follow the instructions of the network management personnel for the effective range of the IP broadcast.

Chapter 6: APPENDIX
1.4. Multicast and Simultaneous Multiple Broadcasts
The multicast communication method can be utilized to make simultaneous broadcasts to two or more units.
The advantage of multicast operation is the possibility of decreasing traffic. Networks that use multicast
communication need to be supported by multicast addresses and Internet Group Management Protocol
(IGMP). The effective multicast address range is from 225.0.0.0 to 238.255.255.255.
Note
Follow the instructions of the network management personnel for the effective range of the broadcast.
1.5. Packet Loss Recovery
The NX-100 and NX-100S convert audio data into IP packets to carry out communications. According to the
condition of the network to be used, packets may be lost, deteriorating sound quality. The NX-100 and NX-
100S offer the following 3 different selection modes for recovering such lost packets.
Standard:
Corrects for lost packets with a silent gap. This method helps reduce delay times and
bandwidth, and is appropriate for applications that emphasize real-time operability. However,
it is not well-suited to networks in which many packet losses may occur, because the good
sound quality cannot be maintained.
Error Correction: Recovers lost packets with redundant data. Since only short-time losses can be corrected,
this method is not appropriate for networks in which many packet losses may occur. It is,
however, appropriate for applications that require high sound quality, such as LAN, which
have lower chances of packet loss.
Resend:
Corrects by automatically resending lost packets. All packet losses that occur within the
preset delay time can be corrected. High sound quality can be maintained even on such
networks as the Internet, which may generate many packet losses. This method, however, is
not well-suited to applications that emphasize real-time operability, because of longer delay
times.

Note: Numbers represent level of advantage in the order of 1, 2, 3.
1.6. Contact OFF Delay Time
Depending on the packet loss recovery setting, delay times may be generated in broadcasts.
Long delay times do not take place in the contact bridge function. Therefore, if the contact is set so that it
becomes OFF when broadcasts are terminated, the contact may be turned OFF before broadcast completion.
To leave the contact ON until broadcast completion, the contact OFF delay time of the NX-100 or NX-100S
that provides contact output needs to be set to be longer than the broadcast delay time in the contact setting.
(The broadcast delay time is displayed on the Broadcast Spec setting screen.)
1.7. Sampling Frequency Correction
Synchronizes all NX-100 and NX-100S operation clocks in the system.
Unless the operation clocks are all synchronized, sound losses can occur in broadcasts that last more than 2
minutes. For example, to realize sampling frequency (fs) correction between units connected to Networks A
and B, perform fs correction data transmission setting for any one of the NX-100 and NX-100S units
connected to Network A. Set the target transmission unit of the correction data to the Network B router IP
address. Set the sampling frequency reception for any one of the NX-100 and NX-100S units connected to
Network B. Add the address translation of the unit set to receive the correction data to the Network B router.
Note, however, that this setting is not needed when limited to use within the LAN*, because the sampling
frequency is automatically corrected.
