WESTERSTRAND LUMEX5 NTP Digital Clock Time System User Manual

General

LUMEX5,LUMEX7 and LUMEX12 are Digital Clocks for indoor use, displaying time in hours and minutes. The time can be displayed in either 12- or 24-hour format. The clock can also be configured to show the time, date and temperature alternately. Light intensity of the digits is adjustable by an automatic dimmer control. 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 foldback IP address 192.168.3.10. Please note, if default settings are used no configuration is needed.
The clock is powered by 230 V mains. In case of power failure, the display is turned off, but the builtin real-time clock will continue to run for 48 hours. When the power is restored it will resynchronize automatically.

Functional description

Start up
When the power cable is connected to the electronics, 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.
Standalone
If the clock does not have an external synchronisation, it operates standalone.

Configuration using R F P buttons

General
Configuration of network settings, light intensity and other parameters is done via a WEB-browser. Some of the parameters can also be set using three buttons located at one side of the clock. Please note, if default settings are used no configuration is needed. The programming is made with push buttons placed on the side of the clock (see below).

Button
[R] Return Enter base mode (display time)
[F] Function Next function / Accept displayed value
[P] Program Enter the displayed function / Increase displayed value. Hold button for rapid count.

Programming time

Setting light intensity
The light intensity for the digits can be adjusted in 8 levels. An automatic dimmer function regulates the light intensity within each level.

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

Configuration using a WEB browser

Login
It is possible to login as administrator or guest. The administrator has the rights to read and to write/change configuration. A guest can read only.

Username
admin or guest.

Password
Enter a password. Default password is password. After the login a function menu will be shown.

Status

Network
Enter general network parameters.

DHCP
Off ­ Static IP address according to static IP below. On ­ DHCP IP address with fallback according to IP fallback below. Fallback: If DHCP is activated this will be the DHCP fallback address.

Static IP To be checked if static IP address is used.
Address: Enter the static IP-address.
Subnetmask: Enter the subnetmask.
Gateway: Gateway IP address.
DNS: IP address of DNS server. Two different addresses can be entered, DNS1 and DNS 2.

Utilities Syslog: Syslog server IP address. Send syslog messages if checked.
Identity access: Identify access is used in combination with application software Wunser. Wunser is a PC program that is used for finding and doing light configuration on Westerstrand Ethernet products. Firmware updates are also handled by Wunser. Wunser uses UDP port 9999 when communicating with other Westerstrand products and UDP port 69 when downloading new firmware. These ports can be open, closed or prepared for encrypted communication. Identify access = Normal ; port 9999 and port 69 is open. Identify access = Password ; port 9999 and port 69 are using AES encryption. The password used is
the same as the administrator login password. Identify access = Disabled ; port 9999 and port 69 is closed.
Telnet: Use of Telnet protocol allowed if checked. Web server: Use of HTTP protocol (web-browser) allowed if checked. HTTPS: Use of secure communication protocol HTTPS (web-browser) if checked.

SNMP This function is used to activate the SNMP, enter the address of one or more SNMP servers and to define the SNMP community. The IP address can be specified as an IP address or as a full domain name. Up to three SNMP server addresses can be entered.

Trap type: This function is used to choose SNMP trap version. Trap type v1 = Trap according to SNMPv1 Trap type v2 = Trap according to SNMPv2

NTP

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.

Clock
Used to configure general clock parameters.

Leading zero Time: not checked; ” 8:29″,checked; “08:29″. Date: not checked; ” 7.9 “, checked “07.9 ” (Sep 7).

Firmware Download / Wunser

General
The Clock has support for firmware upgrade via the network. The utility program Wunser is used for firmware upgrade. Wunser can be downloaded using the following link: http://www.westerstrand.com/archives/download.htm
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 clock is in boot-loader mode, then the green LED on the RJ45-connector is flashing. 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.
Also other programs, e.g. windows built in client tftp, can be used: c:ARMLisa>tftp 192.168.2.61 put LISA-Q132.MOT Successful transfer: 1234092 byte 15 sec., 82272 byte/s

Find IP-address
At delivery, the clock is set to DHCP, with fallback address 192.168.3.10. If this has been changed and is unknown, the clock can be found using Wunser, see manual 4296. The clock is identified in the product list by its MAC-address. Each product is labelled with the individual MAC-address.

Reset Button

At a normal start (Reset Button is not pressed) then the green LED is flashing about 2 seconds. Then the green LED is turned off. When the clock is synchronized the green LED is turned on.
