Introduction

THE MASTERCLOCK MDN MULTIFUNCTIONAL

DIGITAL DISPLAY syncs to an internal or external NTP

(Network Time Protocol) source for accurate, traceable

time. The MDN is also designed to accept several varieties

of Time Code and to provide countdown abilities for up to

100 days. This is our most versatile time-keeping device yet

The MDN features a three-digit Days to Liftoff display (here,

“H” stands for “Hold”).

The first character is alphanumeric. Nine digits follow.

Used strictly as a clock, the MDN accepts both Network

(NTP) and Time Code (IRIG-B12) signals.

For countdowns, the MDN accepts CS3, a NASA count

protocol based on IRIG. This mode includes three “Hold”

signal display choices.

Also for countdowns the MDN accepts CS5, a NASA count

protocol based on a ASCII stream. Within this mode one

chooses either “Count” or “Launch Time” mode.

In “Auto-detect” mode, the clock displays look for CS3 or

CS5. If they find neither, they will display Network or Time

Code signals.

The display can be “blanked” awaiting the next phase or

project.

The MDN features one alpha and

nine numeric 2.3” (5.8cm) LED digits

in a sturdy attractive black powder-

coated steel case. Not designed for

outdoor use, this display can be

remotely configured and operated.

Masterclock MDN User Manual –2013.05.07

Mounting

You can mount your MDN according to your needs. Appropriate

brackets should already be included in your kit.

DESIGNED FOR WALL, RACK OR TABLE MOUNT

Your MDN is designed to fit a variety of surfaces and

environments supported by these sturdy brackets.

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. Mount the

bracket on the wall/conduit box, attach the power cord and

CAT5 Ethernet patch cable and secure the MDN to the bracket

using the supplied retaining screws. See page 35 for a plan view

with precise measurements.

SWIVEL MOUNT BRACKET (OPTION)

First, mount both swivel brackets to the wall, then attach the

signal input cable(s) and power cord and finally secure the MDN

to the swivel brackets using the supplied retaining screws. Angle

up or down to provide the best viewing. Finally, tighten all

screws.

TAKE CARE DURING INSTALLATION

Power and low voltage signal wiring should be installed

according to local electrical codes and to enable access to the

back of this device.

Do not route power or signal cables between the case and the

wall (along the exterior of the wall), which may pinch the power

or signal cable and create a hazardous condition.

Masterclock MDN User Manual –2013.05.07

Configuration Checklist

Your MDN multifunctional display device gets Network time

cues from the Ethernet and also from IRIG Time Code

sources. 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

(page 12). It may be necessary to obtain some or all of this

information from a network administrator in your

organization.

STATIC NETWORKING CONFIGURATION

__ IP address and netmask designation for your MDN

__ Primary and secondary DNS (Domain Name Server)

__ Gateway/router

__ Primary and secondary NTP time references

DYNAMIC NETWORKING CONFIGURATION

__ Confirm that a DHCP/BOOTP service is accessible on the

local network

__ Determine if DHCP server will provide NTP server

configuration

__ Determine if DHCP server will provide Time Zone

configuration

NTP ADDRESSING MODE

__ Determine if this device (client) will query the NTP server

(Unicast mode), listen for NTP broadcast messages

(Broadcast mode), or listen to NTP as part of a Multicast

group.

NAMING

All NTP devices, including your MDN, can and should be

provided with a verbose name (see page 11). The name is

arbitrary and may be useful for organizing and managing

devices once installed. By default, device names are the

product name abbreviation followed by the device’s MAC

address. Customers should designate their own custom

names relating to their own organizational requirements,

32 characters max.

INITIAL OPERATION / SERVER ACQUISITION

After receiving power, the MDN will go through an internal

check. Time from the RTC backup will be applied until the

IRIG-B12 signal or NTP time stamp is acquired.

STATUS LED (LIGHT EMITTING DIODE)

The LED colons between the digits on the display will follow

the protocol after power is applied (operation is

configurable via WinDiscovery or Telnet):

TIME ZONE OFFSETS

The MDN maintains time as UTC initially. A Time Zone offset

or bias can be provided to adjust the time for display

purposes (see page 18). A bias can be set as a positive (+) or

negative (-) value. Expect a resolution of one second.

DAYLIGHT SAVING TIME

An automatic Daylight Saving Time (DST) adjustment can be

configured separately (see page 16) in addition to the Time

Zone offset mentioned above. DST begins on the second

Sunday of March at 2:00 AM (Local Time) and ends the first

Sunday of November at 2:00 AM (Local Time).

EU STANDARD –EUROPEAN UNION

In the European Union, daylight change times are defined

relative to the UTC time of day. Summertime Period begins

at 1:00 AM, UTC on the last Sunday of March and ends at

1:00 AM, UTC on the last Sunday of October.

FREEWHEELING ACCURACY

The MDN has built-in provisions to allow it to freewheel and

maintain accuracy for extended periods in the absence of

Time Code. These features also allow the unit to be set

manually and run without Time Code with precision.

LED STATE

STATUS INDICATION

Flashing Colons

No Reference: The device is not able to reference NTP

Solid Colons

Referenced Time: The device is receiving time

referenced from a NTP server

Solid Colons

CS3 and CS5 are locked during a countdown

If the Time Code input is different from

UTC, do not adjust the Time Zone and/or

DST offset. These will adjust automatically.

Daylight Savings Time (DST) adjustments

must be configured using the daylight time

option and not with the Time Zone offset

option in order to ensure proper year-

around operation.

Masterclock MDN User Manual –2013.05.07

TCXO AND RTC CIRCUIT

The MDN contains a RTC (Real Time Clock) circuit allowing

the clock to maintain an accuracy of ± minute per year to

the last known Time Code or NTP input (± 165 mSec per

day) when Time Code 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.

DEFAULT CONFIGURATION

The factory defaults may be restored by using the

WinDiscovery program, Telnet or by using the reset button

at the rear of the MDN.

Your MDN display ships from the factory with the following

configuration as defined below. The MDN firmware

interprets incoming time signals as UTC.

Masterclock MDN User Manual –2013.05.07

Configuration

The Masterclock MDN 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).

The factory default configuration:

DHCP/BootP provided network configuration

Enabled

DHCP provided NTP server address entry

Query (Unicast) NTP client

Disabled

Time Zone offset

Disabled

Automatic Daylight Savings Time adjustment

Enabled

Telnet access

DHCP/BOOTP AUTO-CONFIGURATION

DHCP (Dynamic Host Configuration Protocol) is a

mechanism for automating the configuration of network

devices that uses TCP/IP. When DHCP is enabled, DHCP

configuration acquisition will overwrite any manual

configuration items.

Factory default: DHCP enabled.

BOOTP was a precursor to DHCP. The MDN can obtain

configuration from a BOOTP server when no DHCP server is

present.

The following RFC2132 DHCP options defined configuration

items are, when available, used by the MDN for

configuration purposes:

OPTION

COMMENTS

Time Offset

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.

Router

The first IP address provided will be used for router/gateway configuration.

Domain Name Server

Up to two server IP addresses may be specified. MDN will treat addresses as

primary and secondary DNS servers.

Network Time Protocol

Server

Up to two server IP addresses may be specified. MDN will treat addresses as

primary and secondary NTP servers.
