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.

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.

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

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.

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

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:

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.
