3.2 Technical Data

See Appendix "H Technical data“.

3.3 Device Description in this Manual

This instruction manual is for the master clocks DTS 4138.timeserver and DTS

4139.timeserver. Below both models (DTS 4138 and DTS 4139) will be referred to as DTS 4138 with the exception of time-keeping.

3.4 Introduction

The DTS 4138.timeserver is a NTP Time Server for use in network environments. It can be synchronized by DCF or GPS (e.g. from GPS 4500), AFNOR-A/C, IRIG-B

and

NTP, and act as a NTP server in a network. It can be used as a master clock for NTP slave clocks, synchronized via unicast or

multicast with NTP and time zone table. It is equipped with 2 LAN interfaces for the operation in two independent networks. In addition, the DTS 4138 provides an IRIG/AFNOR line (available as analog and

digital (current loop and RS422) output), a serial interface for the output of time telegrams as well as an output line for technical pulses (pulse/frequency/DCF).

As the "main“ master clock, the DTS 4138 can synchronize other master clocks or other equipment with DCF and monitor with 1 alarm input.

The DTS 4138 can send both e-mails and SNMP traps for alerting purposes. Using MOBA-NMS and SNMP, the DTS 4138 can be fully operated and its

configuration and system status can be requested. To maintain a redundant time source, two DTS 4138 can be linked by an optical link.

With IRIG-B synchronization the date must be set manually once or by another time source (GPS).

Since the only difference between DTS 4138(S) and DTS 4139 is the quartz, no difference is made on the front plate. It always has DTS 4138.timeserver printed on it. The precise description is made on the identification label on the back.

3.6 DTS Distributed Time System

DTS (Distributed Time System) is a system developed by Moser-Baer AG to connect decentralized master clocks, slave clock lines and time servers. For communication, standard LAN (Ethernet) is used. The DTS can be centrally operated and monitored.

3.7 MOBA-NMS - Network Management System

MOBA-NMS is software used for central management and inquiry of state and alarm information. It supports DTS 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. especially for DTS devices.

Due to the DTS concept, MOBA-NMS can be installed multiple times in one network. With different user rights on the device and software level, the configuration abilities of different users can be set as required.

For DTS devices, all communication is conducted over SNMP V3. The SFTP protocol is used for broadcasting files.

3.7.1 Overview of the main functions

The main MOBA-NMS functions for DTS 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“

 intuitive user interface with input check for the device configuration

 status / alarm request and display on the device group level

 device firmware update for one or several devices (parallel)

 support for device commands, e. g. reset, restart etc.

 back-up / recovery of DTS devices

 transfer of the whole DTS configuration to another device

 user management with different access rights

 monitor for NTP and time zone packages

 editor for time zone files

 online help

 etc.

3.7.2 Device management

All MOBATime network devices are displayed in the so-called device view. Here, the devices can be grouped according to user-defined criteria. For this, the individual devices can simply be moved to the according groups and sorted using drag and drop. There is no limit to the number of groups and sub-groups.

Besides the organizational advantages (easier locating, better overview), a device group has the following advantages:

 commands and device updates can be applied to the whole

group (including sub-groups).

 Alarms and errors of included devices are displayed on the

group level.

 Complete groups can be moved / sorted among

themselves.

The content of the device view can be saved and opened at a later time. The created structure and breakdown into groups is preserved.

5 Installation

5.1 Connections

The connections are specified in Appendix “A Connection diagrams“. Only connect the designated devices to the various inputs and outputs.

5.2 Boot procedure of the DTS 4138.timeserver

The normal booting time of the DTS 4138 is approx. 60 sec. with pre-set IP or with DHCP. The booting procedure of the operating system is displayed on the serial console. After that, the text "starting" appears on the display (during the booting procedure the display is dark and empty). Without connection to a DHCP server, the first start up can take up to 75 seconds. After that, the DHCP option must be set to "off" in the network configuration.

The display “starting“ remains until the time of output to the lines. The duration, depending on the configuration, is 5-30 sec.

5.3 Initial configuration

Per default, the LAN 1 interface is configured with DHCP on. After booting in a network with DHCP server, the received IP address can be displayed.

The LAN 2 interface is configured with the following static settings per default: IP 192.168.1.5, Subnet 255.255.255.0, Gateway 192.168.1.1

If these possibilities do not work out for the initial configuration, the network configuration can be modified using a USB stick. For this purpose, a text file named DTS4138NW.conf is created and filled with the corresponding parameters (not all parameters are required):

IP1:192.168.1.3 SUB1:255.255.255.0 GW1:192.168.1.1 IP2:10.0.0.7 SUB2:255.255.240.0 GW2:10.0.0.1

The insertion of the USB stick is displayed. For taking over the network settings, press the button until the normal time display reappears.

5.4 Firmware

It is recommended to install the current firmware on your device prior to the definite commissioning. The current firmware can be found under www.mobatime.com  Customer Data  Product Ressources  Time Server.

5.5 Basic settings (factory settings)

The basic settings can be found in the table in Appendix “G Parameters”.

6 Operation

6.1 General

Operation occurs via a terminal menu or SNMP. SNMP operation is explained in chapter “9 SNMP“. Operation with the terminal menu takes place either via Telnet or SSH. After a connection has been set up, the login screen is displayed:

To start the menu, dts must be logged in as user. The standard password is dts. (Changing the password  see chapter “6.5.19 General settings“).

Only one menu can be open at any time. The first menu started has priority. The menu is automatically closed after 15 min. without operation, and any possible connection via Telnet or SSH is interrupted.

Backspace:

Backspace must be set to "delete“ with the serial terminal: For example, for HyperTerminal under "File  Properties  Settings - Backspace

sends DEL" must be selected.

Local echo:

Some terminals (serial or Telnet) do not display the characters entered. It is, therefore, necessary to switch on the "local echo" in the terminal.

6.1.1 Telnet

Windows 98, 2000, XP, Vista, Windows 7: Start  Run  telnet [IP-address] Password: by default, no password NetTerm (Shareware)

Linux: Start console and enter “telnet [IP-address]

6.1.2 SSH

Windows 98, 2000, XP, Vista, Windows 7: e.g. with Putty Linux: Start console and enter “ssh dts@[IP address]“

6.1.3 Menu structure

The current menu is always displayed in the menu title. The menu options show all the selectable menu functions. Provided the menu item is not a further menu, the set parameters are displayed. Error messages (e.g. invalid entries) or additional information to the selected menu items are displayed in the response line. The input line shows the current input values or options possible. The status line only appears, when an information has to be displayed, e.g. "An alarm is active".

All entries must be completed with ENTER (Return) (e.g. also ESC). The menu window can always be exited with Ctrl-C (incl. termination of the Telnet and SSH connection). The desired menu can be selected with the relevant number.

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 DTS 4138, or only partial functions, are rebooted.

 With 99, all changes to the menu are reversed and the menu exited.

In the menus where data cannot be saved (command 98), the menu is only exited with 99, but any changes are not saved.

The current menu is updated, without any further entry, with ENTER.

6.5.1 Lines

Under lines, settings can be undertaken for the following functions:

1 DCF - Output  see chapter 6.5.2 2 DCF / Pulse / Frequency output  see chapter 6.5.3 3 Serial Interface  see chapter 6.5.4 4 IRIG / AFNOR / DCF-FSK output  see chapter 6.5.5 5 NTP slave clocks / time zone server  see chapter 6.5.6

6.5.2 DCF – output

The DTS 4138 is equipped with one DCF output line. This line is available on the electrical current loop DCF output.

1. Select line function: off or DCF on

2. Select time zone  see chapter 6.5.25 Time zone selection.

6.5.3 DCF / Pulse / Frequency output

1. Select line function: Line switched off, line DCF output, line pulse output, line frequency output

2. Select time zone  see chapter 6.5.25 Time zone selection.

3. Select pulse mode: every second, minute, hour or user-defined. (Only active with the pulse output function)

4. Select pulse length in ms (1-500ms) (Only active with the pulse output function)

5. User-defined pulse interval (1-3600 sec) only active with pulse type 3 (=user) (the value is also only then displayed). The pulse always occurs after a multiple of the pulse interval from the 0 second in the 0 minute, e.g.: – Pulse interval 960 sec. (16 min.)  Pulse occurs: 00:00:00, 00:16:00, 00:32:00, 00:48:00, 01:00:00, 01:16:00 ... – Pulse interval 25sec  Pulse occurs: 00:00:00, 00:00:25, 00:00:50, 00:01:15, 00:01:40, 00:02:05 ... ... 00:59:35, 01:00:00, 01:00:25 ...

6. Output correction (-500ms...+500ms)

7. Frequency (1…5000 Hz)

Important:

Only frequencies which fulfill the following requirements are to be used, otherwise, phase shifts occur: 20'000'000 / frequency = whole number value

Important:

Frequencies above 2 MHz are not sent out as a square-wave signal anymore.

6.5.4 Serial interface

Serial telegram output via RS232, RS422 or RS485.

1. Select mode: Line switched off / on

2. Select time zone  see chapter 6.5.25 Time zone selection.

3. Com mode:

1 = send RS 232 (receive is not enabled) 2 = send and receive RS232 3 = send and receive RS485 4 = send RS 422 (receive is not enabled)

4. Baudrate: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400

5. Data bit: 7 or 8

6. Stop bit: 1 or 2

7. Parity: none, even, odd

8. Selecting telegram file changes to the menu “SELECTION OF FILE“

Notice:

To set the parameters, the line type has to be selected first.

The description of the telegram function and the telegram file can be found in Appendix E Serial Telegrams.

Selection of the telegram file:

The copy procedure of telegram files is explained in chapter "7.10 Copying Telegram files to the DTS 4138.timeserver“.

6.5.5 IRIG / AFNOR / DCF-FSK Output

1. Select mode: see picture below

2. Select time zone  see chapter 6.5.25 Time zone selection.

3. Configuration of the output voltage level (100 – 5500 mV):

The defined voltage corresponds to the expected output amplitude when power matching (impedance matching) with a load of 50 Ohms is fulfilled. The output voltage is not controlled, resp. it is not adjusted in case of a load change.

4. Configuration of the output voltage level supervision (0 – 2000 mV):

When the output voltage falls below the defined voltage level, an alarm is released.

Selection line function:

6.5.6 NTP slave clocks / time zone server

NTP slave clock line for operating slave clocks on the LAN (Ethernet). With this clock line, a world time function can be realized.

1. Mode of clock line: 0 = off, 1 = Send NTP multicast, 2 = Send NTP multicast and

time zone table, 3 = Send time zone table, 4 = Time zones on request, 5 (only for maintenance) = 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). The port is also needed for requesting time zone entries (mode 4).

4. Poll-interval for NTP Multicast in 2^poll-values in seconds (range: 1 – 16).

E.g. poll-value = 2  interval: 2

= 4 sec., poll-value = 5  interval: 25 = 32 sec.

For redundant Multicast time servers see remark next page.

5. Packet time to Live (TTL) for NTP- and time-zone-Multicast-packets in hops.

(Number of Routers in a network to transfer the packets through; for simple network without routing, enter value "1", for 1 Router enter "2").

6. Repeat time to send time zone table: 10 – 86400 sec.

7. Delay time between the sending of the individual time zone entries (one entry per

Multicast packet) of the table: 1 – 60 sec.

8. Configuration of individual time zone entries. Displays menu “TIME ZONE TABLE“.

Notice:

Changes of multicast address, poll interval and TLL lead to a restart of the NTP server.

Notice:

For the operation of a multicast communication (NTP and Time Zone Server) the configuration of a gateway is required (see chapter “6.5.20 Network”). The gateway can be set manually or by using DHCP. If there’s no gateway available, it’s possiible to set the own IP as gateway.
