Configuration Checklist Our NTDS clocks get their time signals from the Ethernet. Therefore, before installing this device, one should be prepared with the following basic configuration information that the device will require. It may be necessary to obtain some or all of this information from a network administrator in your organization.
STATUS LED (LIGHT EMITTING DIODE) LED STATE STATUS INDICATION Flashing No Reference: The NTDS is not able to reference NTP On Solid Referenced Time: The NTDS is receiving time referenced from a NTP server The LED colons on the display will follow the following protocol after power is applied: TIME ZONE OFFSETS The NTDS digital time display maintains time as UTC initially. A Time Zone offset or bias can be provided to adjust the time for display purposes.
SETTING CONFIGURATION SELECTION Disabled Time Zone Offset Disabled Daylight Savings Time Enabled NTP Client with DHCP Enabled 24 Hour format DEFAULT CONFIGURATION The factory defaults may be restored by using the WinDiscovery program, Telnet or by using the reset button at the rear of each clock. On dual face clocks, the reset button is located on the top. Your NTDS clock/device ships from the factory with the following configuration as defined below.
The following RFC2132 DHCP options defined configuration items are, when available, used by the network device for configuration purposes: OPTION # COMMENTS Time Offset 2 The value provided will be used for the Time Zone offset configuration, unless it is defined as zero in which case it will be ignored and the network device will rely on internal configuration. Note: this option does not provide information appropriate for dynamic Daylight Savings Time use.
IGMP Use of the multicast addressing method requires the use of routers and switches and other network devices which support the Internet Group Management Protocol (IGMP). MULTICAST In addition, the IGMP mode must be enabled and configured for multicast addressing to be implemented properly. Please ensure that your network system components are capable of, and configured properly for, IGMP before utilizing the multicast addressing feature.
WinDiscovery The WinDiscovery software application is a clock setup and configuration program that operates in the Microsoft Windows operating system and is supplied FREE with your NTDS device. INSTALLING WINDISCOVERY To install the WinDiscovery complete the following steps: Insert the CD that shipped with your network device. 1. Run the “setup.exe” application from the CD. 2. By default, the setup utility will suggest installing files to C:\Program Files\Masterclock\WinDiscovery. Click OKAY.
WITHIN THE DROP-DOWN WINDOW: Click on a menu choice to open the window for that function. [PROPERTIES] BUTTON “MASTERCLOCK INC. NTDS CLOCKS” WINDOW The “Masterclock Inc. NTDS Clocks” window lists the name, model, firmware and network configuration of your NTDS clock. These configurations may be changed in other windows, but not in this one. Click [OK] to exit.
[SET TIME/DATE] BUTTON Here you may break the link to UTC time to create a custom time. Click this button to reveal a preliminary warning. Read the warning and continue if you wish to create a custom time for your NTDS clock by unclicking the [UTC] button. By clicking the [UTC] button you will return to UTC time. [STATUS] BUTTON The “Status” window includes a “Display snapshot” of the clock’s face.
GLOBAL PASSWORD The Global Password feature allows the user to enter a single password for all NTP devices using the same password. During this session and subsequent sessions of WinDiscovery, you will not have to enter the password. 1. Check [Enable Global Password]. 2. Type your password. 3. Click [OK] To disable the Global Password, de-select the [Enable Global Password] checkbox and click [OK]. The Global Password being used must match the password on all the devices being administered.
The following pertains only to NTDS models with alphanumeric characters. DAY OF THE WEEK LANGUAGE CHOICE The language (English, Spanish, etc.) for the day of the week display is selected from a drop-down menu on the “Display Properties” window. ALPHA MESSAGE DISPLAY FOR THE NTDS46-12AL To edit the alpha message display on the NTDS46-12AL, go to the “Device Settings” window and click [12Alpha Configuration] (at left). That will reveal the window below.
ADMINISTRATIVE FUNCTIONS From the “Device Settings” window, click [Administrative Functions]. SET TIME AND DATE This feature may be most useful for demonstration, in lab situations, environments where an external reference time signal is not available, when the built-in NTP client is disabled or when a network connection to an NTP server is not available. SET PASSWORD See page 15. RESET DEVICE See page 16. INSTALL NEW OPTION This window will ask you to “Paste the Option Key you received here.
NTP Addressing Modes Setting up to receive NTP is relatively easy to do once you known what you want. UNICAST (QUERY) NTPS clocks and devices support the Unicast Method of NTP (Network Time Protocol) packets transfer. The unicast method involves direct transfer of requested information from the NTP server to the NTP client (clock or other device) based on an automatically generated electronic query or NTP time request.
NTPS clocks and devices also support the broadcasting of NTP packets. The broadcast mode is a widespread or open-ended broadcast, not intended for any specific IP address. Broadcast packets are useful in situations where network administrators may wish to avoid heavy network traffic created by periodic NTP requests. Often such periodic requests end up synchronized, which can exceed the time server’s ability to reply promptly.
Telnet AN ALTERNATIVE WAY TO INTERFACE Telnet is a 40-year-old network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. A terminal-style configuration is available via Telnet. If you are on a non-Windows operating system (like Linux), you will have to use Telnet. WinDiscovery is configured only for the Windows operating system.

Troubleshooting WinDiscovery uses bi-directional UDP messaging on port 6163 for both the discovery process and to communicate configuration and status packets to and from the NTP network device(s). Delivery of UDP messages/packets is not guaranteed. If you experience intermittent problems with WinDiscovery, close the current session and restart the application. If this does not resolve the issue try the following troubleshooting tips, or switch to an alternate method of configuration, such as Telnet.
enabled as a factory-default. In addition, the device will reset its fallback address to one within the link-local address space “169.254.xxx.xxx” when no DHCP server is present or is not able to be reached. Reset the device to initiate a new DHCP IP address request, or use static IP address mode. Consult your network system administrator to ensure that a DHCP server is present and accessible on your network and/or to obtain a list/range of available IP addresses.
If these continue to be ongoing problems, consider the Telnet configuration method or remove the device to an isolated LAN. Clock periodically resets itself Clock appears in red text under WinDiscovery device tree Clock is being assigned an IP address of 169.254.xxx.xxx Clock is showing an “Error” field under the status window in WinDiscovery Possible reasons and solutions: 1. If the configuration of the network device is changed while a “169.254.xxx.
2. Verify that a gateway/router/firewall has been configured that allows the device to communicate outside of its local network. 3. Verify that the IP address configured for the device is correct. If you manually enter or DHCP assigns an IP address that already exists on the network, this will create an IP address conflict. The device will reset its address to one within the link-local address space “169.254.xxx.xxx”. If you see that the IP address starts with “169.
5. The NTP time server(s) is not available or the NTP server being used has the incorrect UTC time. Verify the NTP time server(s) are available and is providing the correct UTC time. “Bad Password” Windows pop-up each time a configuration setting is applied Possible reasons and solutions: 1. 2. You have entered and “remembered” an incorrect password in the password windows.
