General
Digital clock is for indoor application with time display that has 4 digits and colon as time.
The digits consist of 7 segments.
The Digital clock can be configured to show the time/date/temperature alternately in 0-
25sec intervals. Temperature sensor is not included. It is an option.
The clock is prepared for time synchronization by Network Time Protocol (NTP) from an NTP
server. If the connection to the NTP server is lost the clock will continue to run on the built-
in time base.
Configuration of network settings, light intensity and other parameters is done via a WEB-
browser.
The factory default setting for the IP address assignment is DHCP with fallback IP address
192.168.3.10. Please note if default settings are used no configuration is needed.
If the function is activated in summer and winter time, this takes place on the last Sunday in
March and the last Sunday in October, respectively.
The clock has adjustable light intensity.
If power failure occurs the display is turned off. An internal clock counts the time for approx.
48 hours.
After power failure the display is turned on and it will show bars until it is synchronised by a
NTP server. The colon will flash when time from the NTP server is accepted.
Power-Over-Ethernet
Power-over-Ethernet (PoE) is a network standard based on IEEE 802.3af that provides a
means of delivering power to devices connected to the LAN. This technology eliminates AC
electrical wiring, wall transformers, allows centralised UPS backup, and is fully compatible
with both powered and non-powered Ethernet devices. In addition to providing time
synchronisation and control over Ethernet, PoE enabled Ethernet cable provides power to
the clock. System installers need run only a single Ethernet cable that carries both power
and data to each clock. This allows greater flexibility placing clocks and, in most cases,
significantly decreases installation costs. Westerstrand clocks are fully compliant with the
IEEE 802.3af standard for providing power over Ethernet.

Safety
Installation and maintenance of this device must be performed by accredited personnel.
This product must not be installed by unauthorized users/operators. Electrical installation of
the equipment must comply with applicable electrical standards.
Functional description
Start up
When the power is switched on, the clock will display the time from the internal timekeeper.
If no correct time, the display will show lines.
After some seconds, the clock tries to receive a correct time message from an NTP server
and then display correct time.
In case the NTP would disappear, the clock will run on built-in quartz crystal.
Synchronisation
NTP
The clock is prepared for time synchronization by Network Time Protocol (NTP) from an NTP
server. When a correct time message is received the clock will display correct time
automatically.
The colon between hours and minutes will flash when the clock is in sync and the time
message is accepted.
Stand alone
If the clock does not have an external synchronisation, it operates standalone.

View / configure IP address
The Clocks IP address can be either static or dynamic (DHCP). Configuration of IP addressing work
mode is done using a web-browser. The default setting is DHCP.
Using the R F & P buttons it is possible to view or change the current IP-address. It is also possible to
see if the Clock is using static or dynamic IP address.
If the work mode is DHCP it is not possible to change the IP address manually.
To view the current IP address:
In this example we demonstrate IP address 192.168.2.51
1. Push [F] until display shows (IP mode)
IP mode d = dynamic (DHCP), s = static IP

General Description
Westerstrand NTP Clients has several features to achieve a reliable and accurate time. The
configuration of the different facilities is flexible, and the features can be selected or deselected
depending on each customer’s individual needs.
As an 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 the 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 clock
discipline algorithm is also included. This algorithm measures the oscillators drift over a longer period
and makes compensations for the drift.

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.
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 NTP mode=DHCP 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.
Set local Time
Used for manual time setting.
Interval
Interval in seconds between NTP requests.

Remove time at alarm
This function is used to define how the clock should behave during a NTP synchronization alarm. See
Alarm timeout below. If the checkbox is checked the clock will show --:-- in case of synchronization
alarm. If the box is not checked, the clock continues to show time and uses its own built-in quartz
oscillator as time reference.
Alarm timeout
Time in minutes before the NTP synchronization alarm is activated.
Timezone
Select country/time zone. A NTP server sends UTC time. The clock will correct this to local time. If
Daylight Saving Time (see below) is checked it will also and adjust for DST (Daylight Saving Time)
automatically.
Daylight Saving Time
If checked then this timezone uses DST (Daylight Saving Time).

NTP advanced
Advanced NTP settings
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.
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.
