WALL MOUNT BRACKET A wall mounting bracket is supplied which has been designed to fit on either a standard 2”x 4” or 4” x 4” conduit box.
Configuration Checklist Your Masterclock Digital Display gets time cues from the Ethernet. Therefore, before installing this device, one should be prepared with the following basic configuration information that the device will require during installation and installation of the WinDiscovery configuration app. It may be necessary to obtain some or all of this information from a network administrator in your organization.
INITIAL OPERATION / SERVER ACQUISITION After receiving power, the Masterclock Display will go through an internal check. Time from the RTC backup will be applied until the NTP time stamp is acquired.
TCXO AND RTC CIRCUIT The Display contains a RTC (Real Time Clock) circuit allowing the clock to maintain an accuracy of ± minute per year to the last known NTP input (± 165 mSec per day) when NTP is not present or cannot be decoded (i.e. freewheeling mode). MAINTENANCE-FREE RECHARGEABLE BATTERY The RTC is maintained continuously from a rechargeable battery circuit during periods of power outage. Minimum holdover period is two weeks with a fully-charged battery under constant drain.
Configuration The Masterclock display maintains its configuration data in non-volatile flash memory, even when the power is off. These data are configured on screen using either WinDiscovery (page 12) software or Telnet (page 20).
A network device will not function properly if configured to use DHCP services when no DHCP server is available on the network. DEVICE NAME/DHCP NAME REGISTRATION As mentioned earlier, your Masterclock Display should be provided with a custom name (e.g. “reception-north-wall”). By default, device names are the product name abbreviation followed by the last octet of the device’s MAC (Media Access Control) address (e.g. NTDS-A-04:F7).
Installing the device driver Masterclock Digital Display USB DEVICE DRIVER A USB type B port has been included on the rear cover of the clock to configure the clock to allow for firmware upgrades, corrections and enhancements. USB A cable end (to computer) INSTALLING THE DEVICE DRIVER First, power-on the clock. Next, use a USB cable (not supplied) and connect the clock to your PC. The Windows Plug and Play manager will detect a new USB device and request device drivers.
WinDiscovery The WinDiscovery software application is a device setup and configuration program that operates in the Microsoft Windows operating system and is supplied FREE with your Masterclock Digital Display device. INSTALLING WINDISCOVERY To install the WinDiscovery app complete the following steps: Insert the CD that shipped with your network device. 1. Run the “setup.exe” application from the CD. 2.
Colored device description(s) indicate the following status conditions: RED: DHCP is enabled for NTP displays, but the display has reverted to the Microsoft standard fallback ip address. In this situation the last two octets of the ipaddress will represent the Hex-decimal variant of the last digits of display Mac address. BLUE: The device is connected via the USB port on the Windows Computer; this is common when configuring a Timecode variant.
SET PASSWORD The “Set Password” window enables the entry of a new password for each individual device. A password is one to eleven characters and is case-sensitive. For added password strength, you should use a combination of alphanumeric and special ASCII characters (i.e. ASCII character codes 128 – 255). The password must be entered twice to confirm the entry. Click [Change Password] to save or [Cancel] to discard the change.
The [Status] button takes you to the “Status” window (page 16), which includes a Display Snapshot of the digital time display, constantly updated. This update is not ultra-precise, but is meant to give you a remote view of the display from your computer console for troubleshooting and maintenance purposes. Here you can choose settings such as the LED brightness level, format of time, etc. TIME REFERENCE INPUT CONTROL Click the [Input Control] button to reveal the “Input Control” window.
LISTEN FOR NTP VIA MULTICAST Listen/Query Restrictions while listening to NTP broadcasts/ multicasts, the network clock cannot be configured to query the time server. Some NTP/SNTP clients will expect NTP servers to operate on port 123 and cannot be configured to use alternate ports. The static IP address you enter must not be in use by another device on the network, this includes IP address ranges reserved for use by the DHCP server.
LISTEN FOR NTP VIA BROADCAST The network clock can be configured to listen to NTP broadcasts by selecting the “Listen for NTP via broadcast address “255.255.255.255” checkbox. The broadcast timeout is adjustable when this mode is selected. The default configuration is to query the NTP server at 10minute intervals. The clock drift is +/- 1 minute per year, so you can adjust as needed.
STATIC IP To use a static IP address, de-select the checkbox for [Automatically obtain network configuration from DHCP/BOOTP]. You must enter the IP address, net mask, gateway, primary DNS and also a secondary DNS. Devices which have been assigned a fallback IP address of “169.254.xxx.xxx” will be displayed in the main WinDiscovery window with RED text, indicating a problem with the configuration. Port 123 Some NTP/SNTP servers will expect NTP clients to operate on port 123.
DAYLIGHT SAVINGS TIME SETTINGS Click [Daylight Saving Time] to open that window. The clock has complete flexibility to display any Time Zone and DST combination. For setting the DST rules, use one of the following options. 1. Manually enter the daylight saving time rules; or 2. Click [US/Canada Standard]; or 3. Click [EU Standard] (European Union) button. 4. Then Click [Current Windows Setting] to apply the currently configured for your Windows OS. 5. Click [OK] to close the Window.
RESET DEVICE The Masterclock Display may be need a “soft reset” to allow the device to clear its current communications buffer and re-initialize its processing, which includes re-requesting of a DHCP address. This feature is intended to allow the user to remotely reset the unit and does not restore the factory default state. SET TO DEFAULT CONFIGURATION Choose this button to reset the Masterclock Display back to its factory defaults.
Telnet Masterclock Digital NTP Display AN ALTERNATIVE WAY TO INTERFACE Configuration via Telnet may not be convenient for devices operating with a factory default configuration since the IP address is not known. Use the WinDiscovery application to establish first-time networking configuration. For security purposes, the Telnet interface can be disabled. When disabled, you will no longer be able to access the device with Telnet.

Troubleshooting Masterclock Digital NTP Display 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 device(s). Delivery of UDP messages/packets is not guaranteed. If you experience intermittent problems with WinDiscovery, try closing the current session and restart the application.
configuration but no DHCP/BOOTP server is present, the device may not respond to discovery requests for up to twenty seconds after power-on. DHCP configuration is 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.
