General
Westerstrand Analogue NTP Clock with Power over Ethernet (PoE) connection provides the possibility to create a
time distribution system with high accuracy and high reliability.
Initial setting function and error correction is automatic. The movement starts automatically after reception of
correct time.
The hour hand is sweeping and minute hand is stepping.
LAN connection
The NTP clock is equipped with a RJ45 (10BASE-T) connector for direct connection to the LAN via a Power-
Over-Ethernet switch.
Each clock has a unique IP address. The IP address, gateway, subnetmask etc can be set manually (static IP) using
a web browser (or telnet) or it can be set automatically using DHCP (dynamic IP).
The clock has standard IP address 192.168.3.XX and sub network mask 255.255.240.0.
XX could be between 10 up to 200. The IP address is on a label at the clock housing.
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.
NTP
To distribute correct time to different users in a Local Area Network (LAN) the Network Time Protocol (NTP) can
be used. NTP is a part of the protocol family TCP/IP. The unit that sends out the time is called NTP Server and the
clock that receives the time is called NTP Client.

Functional description
After connection of the network cable, the hands are driven to the position 12:00. When the hands have reached
this position the hands will be stopped and wait for the correct time. The hands will not move until the time code
has been accepted. After the receiving process has finished the hands are driven to show the correct time and the
movement starts normal run. The total start up time is approx. 10 minutes.
A correction is done if necessary (when a difference between received time and displayed time occurs). The correct
position of the hour hands is checked two times per day and one time each hour for minute hand.
If the NTP signal disappears, the clock continues to work by means of the built-in quartz crystal.
Installation
1. Connect the network cable.
2. Configure the clock using a normal web-browser.
Please note that if the default settings is used no configuration is needed.
If the IP address is unknown please use the RASER software to search for the clock.

Password
A password is required. Always enter user admin. Default
password is password. If the first letter of the password is
blank no question about user and password will appear.
If you forget the password, then start TELNET. The last line
shows a number of characters within square brackets [].

General >>
Program general parameters
Name Symbolic name, max. 48 signs. This name is shown in the status menu.
Model Type of clock:
Single Single sided without second pointer
Single with second Single sided with second pointer
Double Double sided without second pointer
Double with second Double sided with second pointer
Sec. Pointer Speed of second pointer in interval 9500-10040. A lower value indicates higher speed.
speed (uS) Default value 9800.
A/B Min adj. Adjustment of minute pointer in steps. For a ½-minute model (firmware NUR-B) each step is ½
minute. For a 1/1 model (firmware NUR-A) each step is 1 minute.
E.g. value -1 means ½ minute after for a ½ minute model. Default value 0.
Password Enter a new password. The password must be repeated. Ignore password by setting a blank in the
first position.
Firmware On (Checked): Open the clock for firmware download.
Download After restart this value always is Off. Also see section Firmware below.
If On is set by mistake, then the clock must be restarted
Save Save parameters. If new password was entered then the clock will restart. Then the web reader (e.g.
Internet Explorer) also must be restarted.

RASER
This program are used for finding network clocks. RASER sends broadcast messages on UDP port 9999. All
Westerstrand Ethernet controllers will answer.
Install with setup file SETUP_RASERxxx.EXE (xxx=version e.g. 105). Icon 'RaSer' is created on the desktop.
Start the program. Click on button [Help]. Manual RASER.PDF is displayed. Check this manual for further
information.
Find a Westerstrand Ethernet module
1. Set firmware mask. Examples:
*Search all Westerstrand Ethernet modules (default)
L-H Search only modules with firmware text NUR as first letters, e.g. NUR-A136
2. Set IP mask. Examples:
255 Broadcast to all, i.e. 255.255.255.255 (default)
13 Only show answers from segment 255.255.13.255
3. Click on button [Search]. The box becomes green. Program RASER will timeout after 5 seconds. Break a search
by a click on [Break].
Example: Here a search for all modules with firmware 'NUR*' was made. Total 24 module were found, but only 2
corresponds to mask 'NUR'
