General
The Ethernet module makes it possible to connect a Master Clock to a LAN (Ethernet Local Area Network).
The module can be built into a Marine Master Clock.
The module can be used for Master Clock remote control, programming of relay outputs, alarm distribution,
supervision and for distribution of correct time. The module can be configured to work as a NTP server or NTP
client.
For transmission of correct and accurate time the NTP (Network Time Protocol) is used. NTP is a part of the
protocol family UDP/IP.
When using the Ethernet module for time distribution the Master Clock can act as a NTP primary server or as a
NTP client.
Units connected to the LAN, supporting NTP, can receive correct time from the Master Clock via the network
module.
Included with the Ethernet module is NyToP, Westerstrand NTP-client for Windows XP/7/8/10.
To configure the different parameters such as IP-address, work mode etc. a normal web browser is used.
The front panel of the Marine Master Clock has a Link indicator LED.
Link indicator LED ON = Link activated. The Master Clocks is connected to a network.
LED OFF = No link activated. The Master Clock is not connected to a network.

The Master Clock is working as both Server and Cl
ient.
Status Not Synchronised
The Master Clock has never been synchronised.
Synchronised
The Master Clock has been synchronized at some point, either through manual timing
or via an external time source.
Synchronized in holdover
The main clock works as an NTP client and has received time from an external time
server but has lost contact with the server and has therefore switched to using its built-
in oscillator as a reference.

Synchronized: (192.168.3.7), Stratum=1, Answers=16
The Master Clock is synchronized and gets its time from an NTP server with IP address
192.168.3.7. This NTP server has stratum level 1 and the main clock has received
responses to 16 NTP requests.
Alarms Shows if the Master Clock has any alarms. Example:
No Alarms = The Master Clock is OK.
No Radio = The watch has lost synchronization for a long time.
5-minute limit = Received time message is more than 5 minutes incorrect in relation to
the clock's internal time. The message is not accepted.

General description
Westerstrand NTP Servers has several features to achieve a reliable and accurate time service. The configuration
of the different facilities is flexible, and the features can be selected or deselected depending on each customer’s
individual needs.
The Server can work as NTP Server only or as both NTP Server and NTP Client.
When working as NTP Client the unit has three different ways to determine the most accurate and reliable
candidates to synchronize the system clock. Which model that is used depends on the specific installation and
the customer requirements. The NTP client has also a server list where up to 5 different time servers can be
entered.
The three different ways are:
1. FIRST Always use the first server in the list if available. If not available, take next one.
This suits installations where it is more important to know exactly from where the clients get time than to have
the most accurate time. The other NTP servers in the list will then be more of backup servers.
2. STRATUM Use the NTP server with best stratum. The software sends a request to all servers in the list and
uses the time from the one with best stratum. If same stratum it will use the one that is first in the server list.
This suits installations where it is important that the time is coming from a time server high up in the pyramid.
3. MEDIAN Send a request to all servers in the list and use the median value (the NTP server that is in the
middle). This will filter out all misleading time messages.
In addition to these rules there are some more features such as synchronization limits and a special clock
adjusting algorithm where the speed of internal oscillator is increased or decreased depending on the difference
between the internal clock and the NTP message. All of this to avoid false and inaccurate time and to give a,
when needed, smooth time adjustment without time jumps.
A clock discipline algorithm is also included. This algorithm measures the oscillators drift over a longer period
and makes compensations for the drift.

NTP mode
This parameter defines if the unit shall work as an NTP Server only or both NTP Client and NTP Server.
DHCP option 042
Ask for time using the server IP addresses received from the DHCP server (DHCP option 0042). Maximum 2
NTP servers are set automatically by option 0042. Network DHCP must also be activated to enable this feature.
Broadcast
Accept broadcast/multicast time messages. Broadcast address: 255.255.255.255
Multicast
Accept multicast time messages. Multicast address: 224.0.1.1
NTP server
Select NTP servers, e.g. 192.168.1.237 or as an URL ntp.se. Also see DHCP option 042 above
Up to five different NTP servers can be entered. If the first one fails it will automatically go to the
next one and so on.
Interval
Interval in seconds between NTP requests.

Stratum when no external sync.
With this function it is defined which stratum level the NTP server shall adopt when it has been synchronized
but now is working standalone. Synchronized means that the master clock / time central has received correct
time, either from an external sync source, GPS or similar, or that the time is set manually.
If the NTP server has never been synchronized it will have stratum value 16 and LI-bits of the NTP message is
set to 3 (clock unsynchronized).
Clogging prevention
The NTP server support access control with a call-gap function and can send kiss-o’-death packets if needed.
If this function is activated clients asking for time too often, interval less than 1 second, will be denied and a
kiss-o’-death packet will be sent.
My ID / Key
The NTP Server authentication data. Use for MD5 authentication.
Client
Client mode
FIRST. Always use the first server in the list if available. If not available, take next one.
This suits installations where it is more important to know exactly from where the clients get time than to have
the most accurate time. The other NTP servers in the list will then be more of backup servers.
STRATUM. Use the NTP server with best stratum. The software sends a request to all servers in the list and
uses the time from the one with best stratum. If same stratum it will use the one that is first in the server list.
This suits installations where it is important that the time is coming from a time server high up in the pyramid.
MEDIAN. Send a request to all servers in the list and use the median value (the NTP server that is in the
middle). This will filter out all misleading time messages.
5 minute limit *
With this feature, the acceptance of incorrect time messages can be limited. The reason for this limitation is to
avoid "time jumps" in the event of functional disturbances. If the time message coming from the NTP server
differs more than 5 minutes compared to the clocks internal time, this time message will be rejected.
The default setting is no limit.
Check box = Off; No restriction, accept all messages.
Check box = On; Only accept messages with a maximum time difference of 5 minutes.
* Please note that the Time Central has a general sync. limit feature that affects all modules. See Special
functions, section Sync. Limits. If this feature is activated it overrides the 5 minute limit setting.
Only accept Stratum 1
This function makes it possible to synchronise to Stratum 1 time servers only.
Check box = Off ; synchronise to time server independent of stratum level.
Check box = On ; synchronise only if time server is operating on Stratum 1 level.
Authentication
If authentication is activated: Use MD5 authentication.
Server ID/Key: Authentication data for the external NTP servers configured in the NTP server list.

Firmware Download / Wunser
General
The Master Clock has support for firmware upgrade via the network. The utility program Wunser is used for
firmware upgrade. Wunser can be downloaded from Westerstrand.se
If checkbox Firmware Download is clicked, then the application jumps to a boot-loader. If no firmware upgrade
take place within 60 seconds, then the old application is restarted again with the current firmware. When the
program is in boot-loader mode, then the clock will answer on PING only.
For details of the download procedure, see Wunser manual, 4296.
