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 Setup program's data folder 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 Setup program's entire data 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. 3-2 Chapter 3: SYSTEM SETTINGS (NX-100 SETUP PROGRAM) 2. SETUP SOFTWARE CONFIGURATION AND SETTING ITEMS The Installation Setting Program permits settings of all items including unit scanning and network setting. First set all items using this software at the time of system installation. The following two tools are made available: [Unit Scanning Tool] Performs unit scanning and network settings. Using this tool, first scan the NX-100 and NX-100S units connected to the LAN for the system initial setting. [System Setting Tool] Performs settings of unit broadcast, contact, serial bridge, etc. It is possible to create the system setting file beforehand by entering a unit setting before installation. Setting items table Setting Item Unit Scanning Tool Unit scanning (See p. 3-10) IP address (See p. 3-11) Subnet mask (See p. 3-12) Default gateway (See p. 3-12) System Setup Tool Network (See p. 3-16) Broadcast spec (See p. 3-18) Broadcast pattern (See p. 3-20) Contact (See p. 3-23) Serial bridge (See p. 3-27) NX-100 only System (See p. 3-29) 3-3 Chapter 3: SYSTEM SETTINGS (NX-100 SETUP PROGRAM) 3. SETTING PROCEDURE Pattern 1: Initial On-Site Setup (1) Unit Scanning (Network Setting) • After scanning the unit using the Setup program's Unit Scanning Tool, set the IP address, default gateway, subnet mask, and unit name. • Upload the network setting data. • Save the network setting data in unit setting file format ([IP address].cfg). (2) System Setting Set non-network items using the System Setting Tool. Manually add any units that could not be scanned, and enter their IP addresses and unit names. Set the following items in the order listed: • System: Set audio I/O unit names. • Network: Set the port number. • 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.

• Serial Bridge NX-100 only : Set the units to be connected and their serial ports when using the serial bridge function. (3) Setting Upload

Upload the unit setting file in order to enable the settings set in Step (2) above. 3-4 Chapter 3: SYSTEM SETTINGS (NX-100 SETUP PROGRAM) Pattern 2: Uploading the programmed system setting file after scanning the 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. • Network: Set the port number. • 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.

• Serial Bridge NX-100 only : Set the units to be connected and their serial ports when using the serial bridge function. (2) Saving Data Files

Save the Setup program's data 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. 3-5 Chapter 3: SYSTEM SETTINGS (NX-100 SETUP PROGRAM) 4. STARTUP OF INSTALLATION SETTING PROGRAM Step 1. Either double-click on the Installation Setting Program icon that was created on the desktop during installation or directly double-click on the application [nx100_util.jar] installed in the Software folder. The User Authentication dialog will be displayed. Step 2. Enter the system name and password, then press the OK button. Note: Both the system name and password are case-sensitive. The default system name is factory-preset to "NX-100" and the password to "guest." To change them, refer to p. 3-31. When the system name and password are entered correctly, the initial Installation Setting Program screen is displayed. Tip At startup, the Setup program automatically loads data related to unit setting from the data folder. Step 3. When scanning the unit, click on [Unit Scan (Network Setting)]. TipWhen the settings are saved, a unit setting file is automatically created for each individual IP address and saved in the data folder. If a unit setting file of the same name already exists in the data folder, it is overwritten. 3-6 Chapter 3: SYSTEM SETTINGS (NX-100 SETUP PROGRAM) Step 4. Click on [System Setting] when performing such system settings as broadcast configuration. TipWhen the settings are saved, a unit setting file is automatically created for each individual IP address and saved in the data folder. If a unit setting file of the same name already exists in the data folder, it is overwritten. Step 5. Click on [Password Change] to change the password. Step 6. Click on [End] to exit the program. 3-7 Chapter 3: SYSTEM SETTINGS (NX-100 SETUP PROGRAM) 5. UNIT SCANNING TOOL Scans the units connected to the LAN. Setting data can only be uploaded into the NX-100S and NX-100 units after each unit's IP address has been correctly set by way of either the Installation Setting Program's Unit Scanning Tool or a browser. 5.1. Screen Description Click on [Unit Scan (Network Setting)] on the initial screen. Shown below is an example of the screen displayed after the units have been scanned. (5) (1) Scanned unit list Subnet mask A list showing the units scanned. Displays the subnet mask to be set for the units scanned.

File Save in setting file format (Ctrl+S): Saves scanned unit data to the PC in unit setting file format ([IP address].cfg) 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. 5.2.2. Scan Unit scan: Scans the units connected to the LAN. Change settings: Uploads the settings of the selected unit. IP address: Automatically assigns an IP address and performs related settings. Auto assignment: Automatically assigns an IP address to the selected unit.

Note For bandwidth and multicast streaming, consult with on-site network management personnel. Step 3. Set each item while referring to the bandwidth and delay time indicated in the Information area located at the bottom of the screen. Caution Broadcasts are interrupted when the set bandwidth is displayed in red in the Information area. (The bandwidth is indicated in red whenever this setting exceeds the per-stream usable bandwidth.) (1) Sampling frequency [kHz] Select a sampling frequency for both transmission and reception from [8], [16], and [32] kHz. Sound quality improves with higher sampling frequencies, however this makes the usable bandwidth wider. Caution Local broadcasts are disabled if a transmission sampling frequency of [32] kHz is selected (refer to broadcasting direction in "the Broadcast Pattern Setting" on p. 3-20). 3-18 Chapter 3: SYSTEM SETTINGS (NX-100 SETUP PROGRAM) (2) Packet size Select the size of audio packet. The packet size cannot be changed when [Resend] is selected in the Packet loss recovery item. Smaller packet sizes result in a wider bandwidth, however delay times become shorter. (3) Compression Select [Yes] or [No]. Audio signal compression narrows the bandwidth. To narrow the bandwidth of the network, it is highly recommended that compression be enabled. (4) Packet loss recovery Selects one of three recovery methods used when an audio packet is lost: [Standard], [Error Correction], and [Resend]. Refer to p. 6-4 for details regarding each recovery method. [If "Error Correction" is selected] A scale for setting the correction level appears. Higher settings increase correction capability, however delay times are also made longer. (5) Enable multicast and Multicast address Set whether or not to use multicast for broadcasts. Ticking the [Enable multicast] checkbox makes it possible to enter the multicast address. The effective address range is from (225.0.0.0) to (239.255.255.255).

OUTLINE OF SETTING USING BROWSER Settings can also be changed without requiring installation of the dedicated NX-100 software by individually connecting to each NX-100/100S using the browser*. For NX-100/100S units connected by way of the NAT function, such as an access via internet, perform settings from the browser. * Browsers that ensure correct NX-100/100S operation: Internet Explorer 8, Internet Explorer 7, and Internet Explorer 6 Notes • Settings cannot be performed if the network is not correctly set. In particular, new units shipped from the factory may have duplicate default IP addresses or settings that assume the NX-100/100S is not connected to the same network as the PC. • Complete network settings before using the NX-100 Installation Setting program. If performing setup by the browser, disconnect the unit from the network and connect it directly to the PC's LAN port using a cross cable. • Should the power be switched off during setting changes, the unit may be damaged. • Changed settings are enabled after the NX-100/100S is restarted. Be sure to restart the unit whenever settings are changed. Broadcasts are stopped during unit restart. 2. SETTINGS Step 1. Start up the browser and enter the URL. Note The factory-preset IP address is "192.168.1.1" and web server port No. is "80." When the web server port No. is "80," the description of the port number that follows the colon [:] can be omitted. URL Example <IP address>:<Web server port No.> /admin-e.htm 192.168.1.1/admin-e.htm The User Authentication dialog will be displayed. (Note that the dialog display may differ depending on the browser used.) 4-2 Chapter 4: SYSTEM SETTINGS (SETTING USING BROWSER) Step 2. Enter a user name and password, then press the OK button.

(Range: EVEN numbers 1 – 65526; Factory-preset: 5000) Caution Since UDP port No. 15000 is used by the unit, numbers between 14990 and 15000 cannot be used. (5) Save button Updates the NX-100/100S setting file. Caution Never restart the unit or turn off the power during updates, or while the STATUS indicator on the front panel of the NX-100/100S is flashing. 4-5 Chapter 4: SYSTEM SETTINGS (SETTING USING BROWSER) 4. BROADCAST SPEC SETTING Set the specifications that determine broadcast streaming quality. The NX-100/100S starts its broadcasts based on this setting. This figure represents the NX-100. (1) Navigator Select the usable bandwidth and type of line, and press the Set button. A recommended values will then be set. If no problems are foreseen, perform the setting as is, without changing these values. Note Be sure to consult with network management personnel regarding bandwidth, type of line, and multicast streaming. 4-6 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. 4-7 Chapter 4: SYSTEM SETTINGS (SETTING USING BROWSER) (4) Network Relations [Packet Size] Select the size of audio packet. The packet size cannot be changed when [Resend] is selected in Packet Loss Recovery item. Smaller packet sizes result in a wider bandwidth, however delay times become shorter. [Packet Loss Recovery] Select one of three recovery methods used when an audio packet is lost: [Standard], [Error Correction], 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 (239.255.255.255). 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 Refer to p. 6-4 for sampling frequency correction. [Transfer Setting between Networks] Perform the setting to transfer sampling frequency correction data between different networks. (Correction data within the LAN* are automatically transmitted and received.) * Broadcast effective range No: Corrects correction data only in the LAN, without transferring data to other networks. Reception: Receives correction data from other networks. Enter the receiving source IP address in the corresponding box that is ready for entry. When receiving correction data via Multicast, tick the checkbox of "Receives via Multicast." and enter the Multicast IP address to be used. Transmission: Transmits correction data to other networks. Since the data input boxes for the target transmission unit become ready for entry, enter both the IP address and port number of the target unit. (6) Save button Updates the NX-100/100S setting file. Caution Never restart the unit or turn off the power during updates, or while the STATUS indicator on the front panel of the NX-100/100S is flashing. 4-8 Chapter 4: SYSTEM SETTINGS (SETTING USING BROWSER) 5. BROADCAST PATTERN SETTING The broadcast pattern is determined by the combination of broadcast direction and the units targeted to receive or transmit the broadcast, and is set in the unit that initiates the broadcast. The pattern then starts the broadcast when a contact or program operation input is received. Local broadcasts which do not use the network or single stream broadcasts can also be set as broadcast patterns. (Target receiving unit: 1; Target unicast transmission unit: 1; Target multicast transmission units: 64) Create a new broadcast pattern by clicking on the Pattern Addition button, or select and edit a pattern which has already been programmed.
