Certification of the Producer STANDARDS The Network Time Server NTS was developed and produced in accordance with the EU Guidelines: 2006 / 95 / EC 2004 / 108 / EC 96 / 48 / EC This product belongs to Class A in accordance with EN 55022.
Additional information for the use of the device. Intended Use The Network Time Server NTS is a time server for the use in network environments. It can be synchronized from NTP and be used as NTP server. In addition, it can read the time from DCF or GPS (e.g.
It can be synchronized by DCF or GPS (e.g. from GPS4500), AFNOR- A/C, IRIG-B and NTP, and act as a NTP server in a network. The NTS can provide NTP clocks with NTP and time zone tables via multicast or unicast.
MOBA-NMS is a software used for central management and inquiry of state and alarm information. It supports DTS / NTS devices as well as all MOBATime analog and digital network clocks and can handle a network with more than 1000 devices. This software provides extensive functions for the configuration, installation, back-up / recovery etc.
3.7.1 Overview of the main functions The main MOBA-NMS functions for DTS / NTS devices and network clocks are listed below: automatic device scan over multicast or IP range device management using user-defined device groups see chapter „3.7.2 Device management“...

Boot procedure of the Network Time Server NTS The normal booting time of the NTS is approx. 60 sec. with pre-set IP or with DHCP. The end of the booting procedure is signalized by the Init LED. Without connection to a DHCP server, the first start up can take up to 75 seconds.
3. The IP address is temporarily adapted to the NTS by means of the Windows command ping –l 111 –t <IP address> (l = small L) or the Linux command ping –s 111 <IP address>. The NTS should answer at least two ECHO requests.
Telnet or SSH. After a connection has been set up, the login screen is displayed: To start the menu, nts must be logged in as user. The standard password is nts. (Changing the password see chapter “6.5.13 General Settings“).
The numbers 98 and 99 are always used identically: With 98, the settings entered are saved and the menu exited. Depending on the change, the NTS, or only partial functions, are rebooted. With 99, all changes to the menu are reversed and the menu exited.
MOBA-NMS operation For the configuration of NTS devices via GUI, MOBA-NMS (see chapter „3.7 MOBA- NMS - Network Management System“) can be used. All configuration possibilities are subordinated in different configuration pages (called „tabs“). These tabs are connected to the terminal menu and designated accordingly. Example: The terminal menu „Configuration ...

= Send an empty Time zone table and return to previous mode. 2. Multicast adress for NTP and time zone server: 239.192.54.x Group address: x = 1..15 for MOBATIME devices, e.g. NCI, SEN 40. 3. Multicast port for Time zone server (enter an arbitrary value, empty is not allowed ! Value e.g.: 65534).
As long as the first time server is sending NTP Multicast packets, the packets from second time server are ignored. This configuration is needed, to reach a defined situation for the end devices (the NTS with the more frequently NTP send rate gets higher priority for time reception).
Standard value: 5 Explanation: If the stratum of the NTS equals or is larger than the value “Stratum limits for Synchalarm,” the alarm “Loss of time source str” occurs after a fixed delay of 1 min. Synch LED is turned off! 2.
6.5.10 Alarm mask Display of all the NTS alarms (64) on 4 pages. Pages can be scrolled through with ENTER. An alarm on the current page can be switched on or off by entering an error number.
6.5.19 Time zone selection Display of all the NTS time zones (100) over several pages. The pages can be scrolled through with ENTER. A time zone can be selected on the actual page by entering a time zone number. Only one time zone can be selected.

Packets with a wrong key or wrong check sum will not be used for synchronization. The NTS must be correspondingly configured to be able to use NTP authentication (chapter 6.5.7 NTP Server). The NTP service of the other equipment (e.g. server, PC...) must also be configured.
If one or several variables are set with Put in a configuration group, the variable nts????ConfigCmd must be set at the end to 1 in the corresponding group. The values of the entire configuration group are assumed from the NTS with this command (1=accept).

The following variables are monitored for changes: ntsSysStatus, ntsSysTimeSource, ntsSysStratum, ntsSysMasterMode This Notification is always sent out as soon as SNMP is activated and a destination address is configured.
