Introduction
MCR1000 is a high-precision, yet small profile, Master Clock Reference (MCR) device operating on an Ethernet network
and utilizing a built-in Network Time Protocol (NTP) client to accurately set system time from one or two NTP servers.
When locked to GPS satellites, the MCR1000 can read NTP, NMEA, NENA or time can be set manually. The MCR1000 can generate NMEA, NENA, PPS or PC time via USB.
Optional outputs include NTP, Time Code basic (IRIG-B and SMPTE), Time Code advanced (IRIG-A and E), PPO and 10 MHz sine wave.
Holdover accuracy and stability is maintained with a crystal oscillator that can be upgraded with a High Stability Oven- controlled Oscillator (HSO) option. Each MCR1000 can operate on a 10/100 MBit local area network.
DRIVER INSTALLATION
The MCR 1000 is available in multiple configurations to fit
almost any need with configurable plug-in modules.
A USB type B port has been included on the rear of the MCR1000 to provide a means of configuring the operation of the MCR1000 via software or as a serial data port.
To utilize the USB port with a host computer, connect a USB type A/B cable from the host computer to the MCR1000.
Before the unit can be configured, the device drivers must first be loaded. A software configuration program
(WinDiscovery) and USB drivers have been provided on a CD with the MCR1000.
Installing USB drivers: Once the MCR1000 is powered up, the Windows Plug and Play Manager will detect the new Masterclock USB device and request drivers. Insert the driver software CD into the CD reader of your computer.
When requested by the Windows Plug and Play Manager, select the option to “Install from a list or specific location [Advanced]” in order to manually browse for the drivers. Browse to the drivers located under the Drivers\MCR\ directory on the CD and select [OK], then select [Next].
The driver will automatically load into your computer. If not, see the box at left for other instructions.

WINDISCOVERY
Included with your MCR1000 is the WinDiscovery GUI application. WinDiscovery is a detection, configuration and management software application which works with all Masterclock brand network devices. It operates under most Windows-based operating systems. See page 19 for details.
FRONT PANEL ‘LED’ STATUS
All MCR1000 models have two LEDs on the front panel.
The upper amber LED (labeled: ACT for Activity) pulses briefly and only occasionally with every NTP request.
The lower green LED (labeled: PWR for Power) blinks twice per second during power up, then once per second after synching to the external reference.
OPTIONAL FRONT PANEL DISPLAYS
Optional front panel displays may be ordered with your MCR1000 to provide a time or date display. A six-digit LED shows the current time or date. A nine- digit LED shows the day of year (doy) and current time or date. See page 8 for details.
BATTERY BACKED RTC AND TCXO
The MCR1000 maintains its internal time settings in battery­backed memory located on a RTC chip. A Temperature Compensated Crystal Oscillator (TCXO) provides freewheeling accuracy (maximum drift) down to ±1 minute per year (= 165 mS/day).
A built-in battery supplies power, up to 24 hours, to the TCXO 32kHz oscillator and RTC when the unit is powered off. This allows the internal time to be maintained and the time and date to increment, whenever power is removed.
The battery is a maintenance-free rechargeable manganese lithium type. A built-in battery charging circuit is used when the unit is normally powered, eliminating the need for maintenance.

SET TO FACTORY DEFAULT BUTTON ACCESS HOLE To reset the configuration back to the
factory default insert the end of a paperclip into the pinhole marked here. Push in to depress the “Set to factory default” button inside the unit. Maintain pressure for 5 seconds or until the front panel display goes
to all dashes “- - - - - - “ [if digits are installed].
NON-VOLATILE MEMORY CONFIGURATION
The MCR1000 maintains its configuration parameters internally in non-volatile memory, even when the power is off. These configuration settings include the assigned (DHCP or Static) IP address and network settings, assigned device name, NTP operational mode, brightness level, assigned stratum levels, Telnet access, RTC usage validity during primary reference outages and password. All configuration parameters (except for the time/date stored in the RTC) may be reset to the factory default state.
SET TO FACTORY-DEFAULT CONFIGURATION
The MCR1000 is fully tested with factory defaults prior to shipping. This factory default configuration is defined as:
UTC reference time (no local time zone offset and
daylight saving auto adjustment is disabled)
DHCP configuration mode – enabled
for Network Address and NTP Server addresses
Query (unicast) NTP client mode – enabled
(broadcast/ multicast modes disabled)
Time dissemination via Real-Time Clock (RTC) during
reference outages enabled for 24 hours
Password – set to “public” Device name – set to MCR1000-XX:XX
(where XX:XX are the last two octets of the MAC address of the unit)
Relay Schedule – disabled
(relay actuates upon loss of external time reference)
Telnet – enabled
RESET TO FACTORY DEFAULTS
In some situations (such as a lost password or removal of confidential information, perhaps prior to sending the unit in for repair service), it may be necessary to return the MCR1000 to its factory default configuration. The factory defaults may be restored by using the software interface method (WinDiscovery or Telnet) or by accessing a recessed button located in the pinhole on the front panel (see illustration at left). Insert a paperclip-type wire into the pinhole and maintain pressure for at least 5 seconds to reset the unit to factory defaults.

TIME CODE INPUT NOTICE
Depending on many factors beyond the control of MC, the signals that are received from the Time Code Input Source are subject to interference, noise, loading effects and other influences such as time code format that could cause the MCR1000 with an installed TCR (Time Code Reader) option to provide erroneous time and/or date information and, under some conditions, could prevent it from providing time/date information.
TIME CODE OUTPUT NOTICE
Depending on many factors beyond the control of MC, the time code signals that are generated from the MCR1000 with an installed TCG (time code generator) option are subject to interference, noise, loading effects and other influences, such as a time code format that could affect a device decoding the time code signal to provide erroneous time and/or date information. The time code output of this device should not be relied upon for critical timing applications.
GPS INPUT NOTICE
Depending on many factors beyond the control of Masterclock, the signals that are received from the GPS satellites are subject to interference, fading, satellite failure and other influences that could cause the MCR1000 with an installed GPS receiver option to provide erroneous time and/or date information and, under some conditions, could prevent it from providing time/date information.
It is the responsibility of the user to determine the adequacy and suitability of this device for the intended use.

Configuration, Passwords, UTC and DST
WinDiscovery permits remote network device detection,
configuration and management of Masterclock brand network devices from Windows-based PCs. This is your primary detection, configuration and maintenance software. See page 22.
TELNET INTERFACE – FOR UNIX AND LINUX
A Telnet terminal-style command line interface is used on networks that are not Windows-based (i.e. Linux and Unix). The Telnet interface may be disabled. See page 34.
PASSWORD PROTECTION
The MCR1000 is provided with a password as a security access feature. Each Masterclock network device requires a password that must be entered before the device will accept configuration changes. Each device, or set of devices, can have a unique password or they can all share the same one. The password can be changed and retained to permit access only to authorized users.
A password can be a maximum of 11 characters and may contain any sequence of letters, numbers, and common punctuation. Passwords are case-sensitive.
DEFAULT PASSWORD
The factory default password is “public”
UTC/GREENWICH MEAN TIME REFERENCE
The MCR1000 reference time is based on UTC (Coordinated Universal Time). UTC is the local time at the prime reference meridian at Greenwich, England. At a given location on the planet, local time can be displaced (referenced to UTC) by -11 to +12 hours. The NTP time distribution standard operates with UTC-reference time only. All offsets for time displacements are input at the final stage (e.g. for computers and clocks). Otherwise a double offset might occur.
UTC is sometimes colloquially referred to as "Greenwich Mean Time" (abbreviated GMT).
Masterclock MCR1000 User Manual – v.2013.08.01
Page 11
11
TIME ZONE OFFSETS
A time zone offset (or bias) can be provided to adjust the time for display or time output purposes. A bias can be set as a positive (+) or negative (-) value with a resolution of one second. Factory default: No offset = UTC time.
DAYLIGHT SAVINGS TIME
Daylight savings time (aka: “Summer Time” in Europe) adjustments can be configured separately and in addition to a Time Zone offset.
Daylight time standards vary widely throughout the world. Traditional daylight/summer time is configured as a one-hour positive bias. The new US/Canada DST standard is: one-hour positive bias, starting at 2:00 am on the second Sunday in March, and ending at 2:00 am on the first Sunday in November.
In the European Union, time changes are defined relative to the UTC time of day instead of local time of day (as in US).
To ensure proper hands-free year-around operation, the automatic daylight time adjustments must be configured using the Daylight Savings Time Option and not with the Time Zone offset option.
Factory default: Daylight Savings time is not set.
LEAP SECONDS
UTC runs at the rate of atomic clocks. When the difference between this official time and one based on the rotation of the Earth approaches one second, a "leap second" is added to UTC.
This has virtually nothing to do with the ongoing gradual slowing of the Earth’s rotation over millions of years, which occurs at a much slower rate.

The first IP address provided will be used for router/gateway configuration.
Domain Name
Server
6
Up to two server IP addresses may be specified. NTD clock will treat addresses as primary and secondary DNS servers.
Network Time
Protocol Server
42
Up to two server IP addresses may be specified. NTD clock will treat addresses as primary and secondary NTP servers.
Important Note:
Long DHCP names are not supported. Only the first 14 characters of the device name will be registered by the DHCP server.
The IP address of the unit is required to configure the MCR1000 with Telnet. The DHCP server can be utilized to provide the IP address of the associated device name that is registered.
Important Note:
An MCR1000 network device will not function properly if configured to use DHCP services when no DHCP server is present on the network. An MCR1000 network device will default to a fallback IP address of 169.254.X.Y when no DHCP server is available on the network, where X and Y are random.
DHCP/BOOTP AUTO-CONFIGURATION
The MCR1000 can obtain its network configuration automatically from DHCP or B OOTP, when one or the other is available on the network. Utilizing DHCP/BOOTP, the MCR1000 will automatically be assigned its network configuration. This includes an IP address and additional functions, such as DNS server and Router/Gateway settings. This feature is enabled by default.
DHCP (Dynamic Host Configuration Protocol) is a mechanism for automating the configuration of networked devices that use TCP/IP. When DHCP is enabled, DHCP configuration acquisition will overwrite any manual configuration items.
BOOTP is a precursor to DHCP. The MCR5000 can obtain configuration from a BOOTP server when DHCP is absent.
The MCR1000 can automatically obtain Time Zone Offset configuration and the NTP server addresses (primary and secondary). To utilize these features the DHCP server of the network must be pre-configured with the appropriate checklist items (see below). Factory default: DHCP enabled.
The following RFC2132-defined optional configuration items are, when available, used by the MCR1000 for configuration:

DEVICE NAME/DHCP NAME REGISTRATION
All Masterclock network appliances should be provided with custom device names relating to your own organizational requirements. It is recommended that a robust naming scheme (perhaps based on location) be developed before devices are installed on a campus or throughout a building.
BY DEFAULT: Device names are the product name
abbreviation followed by the last octet of the device’s
Ethernet address (MAC address).
The device name may be changed from the factory default name by entering a unique name of up to 32 characters.
If a DHCP server is available on the network when the MCR1000 is installed, the unit will be auto-registered with the DHCP server. The network system administrator can then view this DHCP name registration and the currently assigned IP address at the DHCP server.
STATIC IP CONFIGURATION
The MCR1000 allows for Static IP address, Gateway and DNS, network configuration entries to be made manually if no DHCP/BOOTP server is available. In addition, the NTP server addresses can be adjusted manually. Manual configuration requires disabling the DHCP defaults via WinDiscovery (or other configuration app).
NTP (NETWORK TIME PROTOCOL)
NTP is an open-standard time synchronization protocol designed for precision synchronization and maintenance of time/date on computers and other devices attached to TCP/IP networks. NTP itself is transported with the UDP/IP (User Datagram Protocol), and is usually served on port 123. NTP time/date is UTC-referenced, as the protocol has no provisions for representing Time Zones or Daylight Savings Time (“Summer Time” in Europe).
A wealth of useful NTP information and resources can be found at
http://www.ntp.org
Masterclock MCR1000 User Manual – v.2013.08.01
Page 14

Note: Use of the multicast addressing method requires the use of routers & switches and other network devices that support the Internet Group Management Protocol (IGMP). In addition, the IGMP mode must be enabled and configured for multicasting addressing to be implemented properly. The implementation of multicasting addressing is beyond the scope of support available from Masterclock. Please ensure that your network system components are capable of (and configured properly for) IGMP before utilizing the multicast addressing feature.
Note: You will need to check with your firewall vendor to determine how to enable multicast traffic through a firewall. In addition you may want to read:
RFC 2588: IP Multicast and Firewalls.
NTP CLIENT
The MCR1000 acquires its internal UTC time reference from an NTP timeserver by using a built-in NTP client. The NTP client is fully configurable and can operate in several NTP modes to reference both a primary and a secondary NTP server. The NTP client can be disabled to allow operation as a stand-alone unit without a network connection.
NTP SERVER OPTION
The MCR1000 can also act as a NTP server with the installation of the NTP Server Option. This option is fully configurable and can operate in several NTP modes. See the optional features section (page 11) for more information.
Warning: If NTP Server is enabled and an offset is created for it, then NTP client must be disabled, else the NTP time served will be erroneous.
NTP ADDRESSING MODES
UNICAST - The MCR1000 supports the unicast method of NTP
packets transfer. Unicast method involves direct transfer of requested information from the NTP server to the NTP client based on a query or NTP time request. The unicast method is supported simultaneously when either the broadcast or multicast modes are selected.
BROADCAST - The MCR1000 supports the broadcasting of
NTP packets. This feature is useful in situations where network administration may wish to avoid the network traffic created by a large number of clients making periodic NTP requests, or in situations where such periodic requests end up synchronized is such a manner as to exceed the MCR1000’s ability to reply. The broadcast mode is a widespread or open-ended broadcast, not intended for any specific IP address.
The MCR1000 provides NTP (UDP) broadcasts using the broadcast address [255.255.255.255].
Note: Some firewalls and routers will not forward UDP broadcasts by default. Security configurations may need to be adjusted to allow the UDP broadcast packets to pass on the configured port.
MULTICAST - The MCR1000 also supports multicast
addressing of NTP packets as a recently added feature. As opposed to broadcast mode (see above), data is sent to every possible receiver (client). Multicasting is useful because it conserves bandwidth. It does this by replicating packets only as needed within the network. It sends packets only to receivers (clients) that want them.
Masterclock MCR1000 User Manual – v.2013.08.01
Page 15

THE CONCEPT OF A GROUP IS CRUCIAL TO MULTICASTING
Every multicast requires a multicast group. The sender (or source) transmits to the group address, and only members of the group can receive the multicast data. A group is defined by a Class D address.
The MCR1000 does not restrict the use of the multicast address assignment and supports the full range of Class D multicast addresses or groups from 224.0.0.0 to
239.255.255.255. These address ranges for multicasting are
defined and governed by RFC3171, IANA IPv4 Multicast Guidelines.
Typically, the multicast address range is from
224.0.1.0 to 224.0.1.255.
The multicast address range from 224.0.1 to 224.0.24 is considered the INTERNET WORK CONTROL BLOCK. This address range is utilized for NTP traffic. Please refer to the RFC3171 for your specific application and implementation.
http://www.rfc-editor.org/rfc/rfc3171.txt
The Internet Group Management Protocol (IGMP) is a protocol that controls group membership for individual hosts. This protocol only operates in a LAN setting, but is required if you wish to be able to join a multicast group on a host. IGMP is defined in RFC 2236.
http://www.ietf.org/rfc/rfc2236.txt
ANYCAST - The MCR1000 does not currently provide anycast
capability.
For more information on How to Listen for NTP see page 32.

CAUTION: Connecting input voltages or switching
currents beyond the maximum ratings for the
relay (up to 24VDC/VAC, 250 mA max) could
damage the MCR1000. Such damage is not
covered under your warranty.
SERIAL PORT INTERFACE
Back Panel Interfaces
RELAY AND PROGRAMMABLE RELAY EVENT
The MCR1000 includes a low voltage dry contact 24V AC or DC relay that can be configured with an internal jumper to be either NO (normally open) or NC (normally closed) using the terminal block connector on the rear of the unit.
Factory default: Jump for NO (normally open).
The relay can provide two mutually exclusive functions.
1. By default: The relay will actuate to indicate when the
unit has lost synchronization (lock) with the external time reference.
2. The relay can be programmed to actuate at a single time
(defined as HH:MM:SS start time) for a specified duration (in seconds) once per day.
Please refer to the specifications section (p. 47) for the maximum relay ratings.
PPS (PULSE PER SECOND) OUTPUT
The MCR1000 provides a PPS output. PPS is commonly used as an on-time mark for timing and synchronizing systems.
The PPS is a 5V TTL (Transistor-Transistor Logic) level signal that is locked to the currently selected and most accurate time reference (external or internal). The rising edge of the PPS signal provides the “On Time” mark. The PPS output is available on the shared I/O connector (Serial Port Interface) on the rear of the unit.
SERIAL PORT INTERFACE
The MCR1000 provides both an RS-232 null modem and USB­type B serial interface for serial communications and configuration. These communications include NENA 911, NMEA 0183 and Kinemetrics/Truetime.

• Monitor the front panel for power up status.
When power is first applied the initial sequence of
the front panel LEDs are:
Front panel PWR and ACT indicators will be off, but
after about 30 to 40 seconds…
Units with 6-digit or 9-digit LEDs will show all dashes
followed by all 8s, then all LEDs extinguish briefly before displaying time
Amber (ACT) LED signifying NTP status: Off Green (PWR) LED: Blinks twice per second, with
numerals incrementing each second. This indicates lock to internal TCXO oscillator and acquiring lock to an external source, if applicable.
Green (PWR) LED: Blinks once per second. This
indicates synchronization to an external reference
CONFIGURE THE MCR1000 USING YOUR PREFERRED METHOD
At this time, the MCR1000 can communicate with WinDiscovery, which can detect and identify the MCR1000 through the exchange of broadcast messages, even when TCP/IP networking parameters are not configured on the same network.
Once the MCR1000 has a valid network configuration and the IP address of the unit is known, it can also be accessed and configured via Telnet by computers in the same network.

WinDiscovery Installation and Operation
Included on CD with your MCR1000 is the WinDiscovery software application for detection, configuration and management of all your NTP devices from Masterclock. The application operates in the Microsoft Windows OS.
INSTALLING WINDISCOVERY
If you haven’t already done so, insert the CD that shipped with your MCR1000 to automatically install WinDiscovery. If AutoRun is not enabled on your computer:
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.
3. Click the [OKAY] button.
USING WINDISCOVERY
Open WinDiscovery from the “Start Menu” or by double-
clicking the shortcut icon on the desktop.
Click the [Discover] button to reveal all the devices accessible on the network. The status bar will display the count of devices found. When complete (please wait until ‘100%’ appears then disappears), a list of device families and groups will be displayed in the left pane of the WinDiscovery window. Click the [+] buttons to reveal the individual devices. Click the [-] buttons to hide them.
Each device is configured with a device name from the factory. Each device name includes the model name and a MAC address extension.
You should change the device name to one that can identify the location of the device.
It is highly recommended that only one user opens WinDiscovery at a time. Other methods should not be used to manage the network devices while using this app.

Note: Some NTP/SNTP clients will expect NTP servers to operate on port 123 and cannot be configured to utilize alternate ports.
DS > IC > NTP CLIENT
While on the “Input Control” window, click the [NTP Client] button to access settings for the NTP client.
ENABLE NTP CLIENT – is enabled by default. However, it may
be desirable to disable the NTP client for certain applications, such as those in which the MCR1000 will not reside on a network during typical operation. Deselect “Enable NTP client” if desired.
The network client can be configured to either query the NTP time server at a selected interval, to listen to NTP broadcasts only, or to listen to multicast broadcasts.
NTP CLIENT SETTINGS
QUERY NTP SERVER FOR TIME – is enabled by default. This is
the unicast mode. The default configuration is to query the NTP server at 10-second intervals.
LISTEN FOR NTP VIA BROADCAST ADDRESS – The MCR1000
can be configured to listen to NTP broadcasts by selecting the “Listen for NTP via broadcast address [255,255,255,255]” checkbox. When this is selected, the broadcast timeout period (in seconds) is adjustable. To configure the device to only listen to NTP broadcasts, click the checkbox [Listen for NTP broadcasts only] and
enter a “Broadcast/ Multicast Timeout” in seconds. The
default timeout is 3600 seconds (1 hour).
LISTEN FOR NTP VIA MULTICAST ADDRESS – The MCR1000
can be set up to listen to NTP using multicast addressing
by selecting the “Listen for NTP via multicast address”
checkbox. When multicast mode is selected, the client will also listen to broadcast messages.
When enabled, the Multicast Class D/Group Address may be specified as well as the frequency that multicast broadcasts will be issued. This can be changed as desired. The NTP client can listen for NTP multicast broadcasts using the full Class D/Group Address range. The NTP client does not restrict the use of the multicast address assignment and supports the full range of Class D multicast addresses or groups from 224.0.0.0 to
239.255.255.255.
These group addresses are defined and governed by
RFC3171, IANA IPv4Multicast Guidelines.
Typically, the multicast address range 224.0.1.0 to
224.0.1.255 is utilized for NTP traffic. Please refer to the
RFC3171 for your specific application.

How to Listen for NTP
DS > IC > NTP CLIENT
To access the NTP addressing modes in the “NTP Client” window, click on the [NTP Client] button on the “Input
Control” window (at left).
NTP CLIENT SETTNGS BOX
QUERY NTP SERVER FOR TIME (UNICAST) – The MCR1000
supports this method of NTP packets transfer by default. There is a query and direct transfer of information from the NTP server to the NTP client. Whenever the broadcast or multicast modes are selected the unicast method is also supported simultaneously.
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] radio button.
The broadcast timeout is adjustable under the [NTP Client Advanced Settings] button at the bottom of this window. The default timeout is 3600 seconds (one hour).
The default broadcast configuration is to query the NTP server at 10-minute intervals. In this mode the clock drift is ±1 minute per year, with adjustments as needed.
MULTICAST – The network clock can be set up to listen to
NTP using multicast addressing by selecting the [Listen for NTP via multicast address] radio button.
When enabled, the Multicast Class D/Group Address (Class D 224-239.xxx.xxx.xxx) may be specified as well as the frequency that multicast broadcasts will be issued.
This can be changed as desired in the “Primary NTP server” and “Secondary NTP Server” menu boxes in this
window. These groups (or Class D address ranges for multicasting) are defined and governed by RFC3171, IANA IPv4 Multicast Guidelines.
Typically, the multicast address range from 224.0.1.0 to
224.0.1.255 (aka: Internetwork Control Block) is used for NTP traffic. However, please refer to the RFC link below for your specific application and implementation.
http://www.elook.org/computing/rfc/rfc3171.html

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. If a static IP address creates a duplicate IP address condition, the network clock will be assigned a
fallback IP address of “169.254.xxx.xxx.”
The “169.254.xxx.xxx” address is a link local address
range (not allowed on the Internet) that is used by Microsoft whenever their DHCP clients cannot find a DHCP server.
NTP SERVER NAMES BOX
The default factory setting for network configuration is to [Use NTP server provided by the DHCP server] checkbox.
Fallback Address – If a DHCP server cannot be found on the network by the NTP clock, the IP address will be assigned a fallback IP address of 169.254.xxx.xxx.
If you choose to deselect the default server, you must provide a static IP Address, here called the “Primary NTP Server:” Then provide a “Secondary NTP Server”.
Similarly, back under the “Device Settings Window,” click the [Network Configuration] button and de-select the [Automatically obtain network configuration from DHCP/BOOTP] checkbox. Then provide the IP address, Netmask, Gateway, Primary DNS appropriately.
Devices that cannot find the primary server and 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.
NTP CLIENT AUTHENTICATION SETTINGS
The NTDS series uses the MD5 Message Digest Algorithm, which is a widely used cryptographic hash function that produces a 128-bit hash value.
http://en.wikipedia.org/wiki/MD5
NTP CLIENT ADVANCED SETTINGS
From the NTP Client window, the [NTP Client Advanced Settings] button allows for the adjustment of additional
network communication settings. Under most operating circumstances it is not necessary to change these settings.
The factory-default TCP/UDP port for NTP service is: “123”
Masterclock MCR1000 User Manual – v.2013.08.01
Page 34
34
Port 23
Some NTP/SNTP servers will expect NTP clients to operate on port 123.
If the advanced settings have been altered for your clock and you begin experiencing difficulty in getting your clock to synchronize to the NTP time server, or the clock begins acting erratically, try returning the advanced settings to the default values: “23.”
Using Telnet
TELNET OPTION
Typically in Windows OS you’ll use the free WinDiscovery app to establish first-time networking configuration. However, in other operating systems you may use Telnet to configure your DHCP server.
To access the Telnet button, go back to “Device Settings” and click the [Communications Control] button. In the
“Communications Control” window, click the [Telnet Control] button and select [OK]. By default the Telnet Port is set at 23. If you wish to change it, deselect the [Allow Telnet Configuration] checkbox and click [OK].
PORT DEFINITION – If Telnet is allowed, the port must be
defined. The default Telnet port is 23. See your network administrator if you need additional information.
IP ADDRESS – If Telnet is allowed, the IP address of the unit is required. By default, the MCR1000 is configured to obtain an IP address via DHCP. Configuration via Telnet may not be convenient for devices operating with a factory default network configuration since the IP address is not known.
Telnet username: public. Telnet password: public.

GPS ANTENNA – SMA FEMALE
Masterclock highly recommends using only the pre-made/pre-tested antenna cables provided by Masterclock, Inc. For best performance, it is best to order these cables (see available antenna packages, page 37) at the same time that you order your MCR1000 with GPS option installed since the unit has been factory tested as a system with the antenna cables and antenna before shipment.
Note: All components of the GPS system (including the MCR1000 unit with GPS receiver, power supply, GPS antenna and antenna cable)
are tested as a system at the factory before
shipment.
Be sure:
1) the GPS antenna, the MCR1000 and the
supplied coaxial antenna cable have not been damaged;
2) the GPS antenna has an unobstructed view
of the sky;
3) the power connector is properly installed;
4) and the front panel LED follows the startup
sequence described earlier (on, off and then on).
GPS Input Option
With the GPS input option the MCR1000 derives precision UTC time from satellites. The MCR includes an internal receiver that requires a pre-amplified GPS antenna.
GPS ANTENNA CONNECTIONS
1. Disconnect power from the unit.
2. Provide the antenna with a clear view of the sky. Do not
move it again until after the MCR1000 has achieved satellite lock (explained below). Route the antenna cable to the back of the MCR1000.
3. Connect the antenna cable coaxial connector to the gold
SMA female connector on the rear of the unit (labeled ANT in image at left).
4. Reapply power to the MCR1000.
START-UP AND GPS SATELLITE ACQUISITION
When the MCR1000-GPS is initially powered up the time to acquire satellites and extract correct time is typically 5 to 15 minutes. In less than optimal conditions this could extend to 25 minutes. Atmospheric conditions, type of antenna, antenna location and antenna cable length will affect acquisition time.
When restarting, if the location, time and number of satellites have not significantly changed since last power down, the MCR1000 should start up much faster.
GPS LOCK RELATED ISSUES AND TROUBLESHOOTING TIPS
The following problems are specific to the MCR1000 with GPS option installed. These should be considered only after the 25-minute satellite acquisition time has elapsed.
PROBLEMS:
Unit is not locking to GPS.
The LED on the front panel is always steady ON.

SYMPTOMS, REASONS AND SOLUTIONS
STEADY ON: The reference lock LED stays steady ON when
the unit has not locked to GPS and is not serving NTP time.
FLASH ONCE PER SECOND: The reference lock LED (page 5, green, PWR) will flash once per second when locked to GPS.
FLASH TWICE PER SECOND: The reference lock LED (green, PWR) will flash twice per second when freewheeling (running without external signal, reference from internal oscillator).
The MCR1000 must first acquire an initial lock to GPS before it will serve accurate time. Once locked, the unit can continue to serve time (either while locked to GPS or while freewheeling) as long as the DC input power is not interrupted.
Some procedures to consider:
1. Wait at least 20 to 30 minutes if installing the GPS
receiver device in a new location. The GPS receiver must find and acquire the signal from at least four GPS satellites simultaneously and will continue to acquire up to the eight satellites. When placed in a new location, time to first lock can be quite lengthy since the receiver must update its internal almanac and ephemeris data from the satellite signals.
2. Make sure the GPS cables and connectors are not
damaged and the threaded connectors are tightly coupled.
3. Relocate and reinstall the GPS antenna outdoors with a
clear/unobstructed view of the sky. Find a rooftop or similar location such as a large open field or parking lot with an unobstructed view. While the MCR may lock to GPS on some occasions with the antenna located indoors near a window, such use is not recommended. Your GPS antenna must not be near satellite dishes or sources of RF interference, such as transmitters or other antennas.
4. Replace your cable and connectors. Your antenna cable
or connectors may be shorted or open.
5. Check your cable length. You may be using too long of an
antenna cable or using an improper impedance cable. If necessary, remove the long antenna cable and connect the MCR1000 directly to the short cable on the GPS antenna using the short SMA male to SMA male adapter provided with your antenna package. Preferred and tested GPS antenna cable is available from Masterclock in lengths up to 500 feet (152m).

Note: Damage to the GPS receiver is not covered under warranty.
If you need uninterrupted precise time, please purchase a spare MCR1000 with a GPS option. Order your first MCR1000 with additional TCR or HSO as a backup reference.
For repairs contact technical support at Masterclock (see page 56 for contact).
Note: Damage to the GPS cables is not covered under warranty.
If the GPS antenna or cables are damaged please contact Masterclock to order replacements.
GPS antenna cannot be repaired.
The MCR1000 with a GPS module installed requires a pre-amplified antenna. The MCR1000 provides +3 VDC via the center pin of the SMA coaxial cable/connector for remote power to the antenna.
WARNING: Attaching a passive (non-pre­amplified) antenna to the MCR1000 could destroy the GPS receiver module. This is a major repair cost which is not covered by warranty.
6. Internal damage: The GPS receiver located within the
unit may have been damaged during the installation or handling. Handle the MCR as you would any electronic device. Do not subject the assembly (particularly the antenna input connector) to electrostatic discharge (ESD) during handling. When handling or installing the device, observe proper ESD protection methods. At a minimum, discharge yourself to a convenient ground before handling theMCR. Preferably, use a static discharge wrist strap connected to Earth ground when handling, installing and/or configuring the device.
7. Inappropriate power application: The MCR-GPS option
provides power to the pre-amplified GPS antenna using low voltage supplied on the center pin of the antenna cable. To avoid damage to the GPS receiver (and/or antenna) caused by a short circuit, make all antenna connections only after all power is removed from the unit.
8. Incompatible antenna: Do not use antennas provided by
others. They may not be compatible with the GPS antenna supplied with your system and may damage the MCR-GPS receiver unit.
9. Damage during installation: The GPS antenna cables can
be damaged by pulling and twisting the connectors. You should also avoid pinching and over-bending the cables. Such abuse may occur while using a cable puller. Ensure that you do not pull directly on the connectors during the installation. Ensure that you do not twist the connector at the location where the connector meets the cable, as this can damage the braid. The coaxial cable should not be crushed, crimped or bent at a sharp angle nor should it be strained by pulling.
10. Coiling If the cable is to be coiled for storage, the coil
diameter should be at least six inches for quarter-inch cable, twice that for larger cable diameters.
If your GPS antenna cables are damaged please contact Masterclock to order replacements.

NMEA and the RS-232 Interface
DS > OC > NMEA
In order to receive NMEA (National Marine Electronics Association) 0183 sentences (messages), the RS-232 interface [DB-9 male connector] may be used to connect your PC with your MCR1000.
Unless the GPS option is included, only ZDA sentences will be output as they contain only UTC time and date signals. Other sentences with latitude and longitude data are available with the GPS option (page 40).
SERIAL PINOUT FOR RS-232
The MCR1000 serial port pinout is defined at left. RS-232 communications
from a standard IBM PC or compatible host computer use a standard straight thru cable (3 wires only: pins 2, 3 and 5).
The default communication settings for the RS-232 port are: 4800 baud, 8 data bits, 1 stop bit, no parity.
The RS-232 port can be configured for baud rates of 4800, 9600, 19200, 38400, and 57600; along with 7 or 8 data bits, 1 or 2 stop bit. The parity bits can be selected as None, Odd, and Even.
FOR OTHER TYPES OF RS-232 RECEIVERS
it may be necessary to observe the following requirements:
• Connect the Transmit (TX) line of the MCR (pin 3 of the DB-9 connector) to the Receive (RX) line of the host system.
• Connect the Receive (RX) line of the clock (pin 2 of the DB- 9 connector) to the Transmit (TX) line of the host system.
• Connect the Ground Line of the clock (pin 5 of the DB-9 connector) to the ground of the host system.
• Ensure the host system can communicate via standard RS-232 at 4800 baud, 8 data bits, I stop bit, no parity.
• Pins 2 and 3 must use RS-232 voltage levels. The MCR1000 cannot decode TTL-level serial communications at pin 2 and 3 of the DB-9 connector.
Masterclock MCR1000 User Manual – v.2013.08.01
Page 40
40
• Ensure that any cable you are using for communication
with the MCR1000 is within the RS-232 standard length and is a working cable.
• The interface may require a null modem cable.
• A “null modem” 3-wire serial cable or simple RS-232 cable
utilizing pins 2,3 and 5 only should be used
ADDITIONAL NMEA MESSAGES TO OUTPUT WITH THE GPS OPTION
The MCR1000 can output additional NMEA 0183 sentences (aka: messages). If you have the GPS option these can be accessed by simply checking the appropriate boxes (at left) on the “NMEA Message” page.
ZDA - GSV GGA GLL GSA RMC VTG
Note: Selecting more than two NMEA sentences may cause
the sentences to be output every other second as opposed to every second. This characteristic is an inherent function of the GPS receiver and is particularly true when selecting GSV sentence output.
When GSV is selected, up to three GSV sentences will be output with information coming in from at least four satellites per sentence. It would help to manually increase the baud rate (maximum = 57600) when adding additional sentences to help increase delivery capability.
SELECT NMEA OUTPUT PORT
The first two selections (RS-232 and USB) produce a “Port Settings” window (lower left) with preselected [Baud rate],
[Parity], [Number of Data Bits] and [Number of Stop Bits] buttons.
RS232 PORT SETTINGS
On the “NMEA Messages” window select the [RS232 settings] button. Click on the [Port Settings] button to adjust
the baud rate and communications settings. Select from baud rates of 4800, 9600, 19200, 38400, 57600 and 230400.
The parity bits can be selected as None, Odd, and Even.
The number of Data Bits can be set to 7 or 8.
The number of Stop Bits can be set to 1 or 2.
The default settings are 4800 baud, 8 data bits, no parity, 8 data bits and 1-stop bit.
THE USB BUTTON REVEALS SIMILAR SETTINGS.

NTP Client Information
If you want to synchronize PCs, workstations and servers to your MCR1000 you must incorporate a NTP/SNTP client. This client is responsible for asking the NTP server for time/date information. In some cases it simply listens on the network for NTP time broadcasts, then sets the internal time of the computer or device. NTP client applications come in a variety of offerings, supporting different features, with different levels of accuracy, fault tolerance and reporting. Many are inexpensive to license, or are free (like this client app from Masterclock).
FREE SNTP CLIENT SOFTWARE
Masterclock provides a FREE Simple Network Time Protocol (SNTP) client for use to synchronize PCs, workstations and servers. This client app is called MasterSyncPC Freeware and it can be downloaded at the Masterclock website.
https://www.masterclock.com/MasterSyncPC2.php
The software is provided as-is, as a courtesy to our customers, with no technical support provided. This application is developed to run under Windows 2000, Windows XP, 7, Server 2003 and 2008 SP-1.
Masterclock MCR1000 User Manual – v.2013.08.01

Synch Problems? If the advanced settings have been altered for your device and you begin experiencing difficulty in getting your clock to synchronize to the NTP time server, try returning the advanced settings to the default values shown above.
Also do this if the clock begins acting erratically, performing soft restarts, etc.
“Soft” Restarts
A ‘soft’ restart may be performed periodically by the MCR1000 to automatically rectify problems it senses:
1. If the MCR is not receiving NTP poll responses;
2. If the MCR is not receiving broadcast responses;
3. Or if the MCR is set to use DHCP and cannot find it.
You will recognize a soft restart when the MCR1000 green PWR LED begins to blink twice per second for a short time. You may even hear a quiet relay click.
THE TIMEOUT PRIOR TO A SOFT RESTART IS TEN MINUTES OR MORE
Several factors can increase the time between soft restarts.
1. All soft restarts will be delayed by two hours if a
connection is made by Telnet or WinDiscovery.
2. A soft restart could be delayed if the user changes the
default parameters for NTP poll retries/timeouts or the NTP broadcast times out. For example, if the NTP broadcast timeout is increased to 60 minutes, the soft restart timeout will also be increased to 60 minutes.
The primary and secondary server information (at left) can be automatically configured by the DHCP server when selecting the [Use NTP server(s) address provided by DHCP server] checkmark, provided your DHCP server is configured to do so. Consult an IT/network administrator to utilize this option [DHCP Server Option 042].
The default port for NTP service is 123. This can be changed if desired. [Note: Some NTP/SNTP servers will expect NTP
clients to operate on port 123 and cannot be configured to utilize alternate ports.]
Some NTD clocks will only operate in Unicast/Query mode using server port 123. This mode is selected exclusively when neither the “Listen for NTP Broadcast” nor the “Listen for NTP Multicast” modes are selected.

Software Tip:
WinDiscovery uses bi-directional UDP messaging on port 6163 for both the discovery process and to communicate configuration. It also sends status packets to and from all Masterclock network devices on this port.
Delivery of UDP messages (packets) is NOT guaranteed.
Intermittent problems with WinDiscovery? Try closing the current session and restarting the application. If this does not resolve the issue try some of the trouble shooting tips listed here. If this fails, switch to an alternate method of configuration, such as Telnet.
Note: If this does not resolve the detection problems you may additionally configure to pass through both directions UDP broadcasts on ports 6165, 6166, and
6264.
Note: DHCP configuration is enabled as a
factory-default. In addition, the clock will reset its address (during fallback) to a default address within the link-local address space (169.254.xxx.xxx) when no DHCP server is present or is not able to be reached.
Troubleshooting Tips
All MCR1000 units are fully checked and system tested at the factory for proper operation before shipment. Unless physical damage is found, the unit is probably functional.
The following problems can probably be readily solved by the customer/user.
PROBLEM:
Unable to find (discover) the new MCR1000 on the WinDiscovery network of devices
POSSIBLE REASONS/SOLUTIONS:
1. Verify that you have supplied power to the MCR.
2. Verify that all the network cables, hubs, etc. are in
proper working order.
3. Be sure that no Ethernet crossover cables are being used
where inappropriate.
4. After clicking the [Discover] button, wait until the status
indicates 100% completion.
5. Verify that the MCR is a Masterclock brand device.
WinDiscovery is not designed to work with products from other vendors.
6. Verify that the MCR is on the same physical network as
the computer from which you are running WinDiscovery.
7. If the computer is separated from the MCR by a router
(on a remote network) or a firewall it is likely that the router/firewall is blocking communication with the device. Run WinDiscovery from a computer within the remote network, or ask a network system administrator to configure the router/firewall in question to pass through (in both directions) UDP broadcasts on port 6163
8. Unfortunately, some routers will not forward UDP
broadcasts across networks, but WinDiscovery requires this. If you are running a personal firewall product, such as ZoneAlarm or BlackICE, or the built-in Windows firewall, you must adjust their configurations to pass through (in both directions) UDP traffic on port 6163.
9. Verify that the hub/router/switch is capable of
supporting the 10/100MB speed the MCR requires.
Masterclock MCR1000 User Manual – v.2013.08.01
Page 45
45
Potential Network Topology Communication Problems
Networks separated by physical routers will often block UDP broadcasts preventing WinDiscovery from locating devices on a remote network.
Under such circumstances, WinDiscovery must be operated from a computer within the remote network. Or the routers separating the networks must be configured to pass bidirectional UDP traffic (including broadcasts) on port 6163.
Consult your network administrator for additional information.
Personal or network computer firewall applications, such as ZoneAlarm©, BlackIce, Symantec Client Firewall, or the Windows OS firewall may also prevent WinDiscovery from operating correctly. Configure the firewall to allow bidirectional UDP traffic on port 6163 or temporarily disable the firewall while using WinDiscovery.
10. Verify that a DHCP/BOOTP server is present on the
network. If the MCR has been configured to use DHCP for network configuration, but none is present, the MCR may not respond to discovery requests for up to twenty seconds after power-on.
11. Reset the MCR to initiate a new DHCP IP address request,
or use the static IP address mode.
12. Consult your network system administrator to obtain a
list or range of available IP addresses.
PROBLEMS:
1. WinDiscovery finds the MCR1000, but the status display
is intermittent or not updating.
2. The MCR1000 clock is not responding to configuration
changes made in WinDiscovery.
3. Now that the MCR1000 is hooked up other device(s) do
not appear in WinDiscovery.
4. The status or settings characters are garbled.
POSSIBLE REASONS/SOLUTIONS:
1. WinDiscovery may have been left open too long and the
MCR’s configuration may have changed during the session. This can occur if the DHCP server has issued new or refreshed addresses without alerting you. Remedy: close and restart WinDiscovery.
2. The discovery process was not complete before selecting
your device. After clicking the [Discover] button, please wait until the status indicates 100% completion.
3. Verify that the physical network cables and equipment
and configuration for UDP have not changed.
4. Verify that you are currently the only user accessing the
device via WinDiscovery or Telnet.
5. Heavy network traffic reduces the bandwidth and/or
causes collisions with the UDP messages/packets. Heavy traffic can cause WinDiscovery to show outdated or garbled information. Remedy: Press the [Discover] button again and wait until the process completes to refresh WinDiscovery.
6. Take steps to increase the bandwidth and/or reduce
network traffic. If this is an ongoing problem, consider the Telnet method or move the MCR to an isolated LAN.

Note: 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.
IMPORTANT NOTE: if the configuration of the network device is changed while a 169.254.xxx.xxx is being use, then the current 169.254.xxx.xxx address will become the permanent static address and the original conflicting static address is lost. At this point, it is necessary to manually change the static IP address to a one that will not conflict, or you may have to do a
“Reset Configuration” to restore the
system to factory default settings.
PROBLEMS:
1. MCR1000 name appears in RED in the WinDiscovery.
2. MCR1000is assigned an IP address of 169.254.xxx.xxx.
3. MCR1000 is not maintaining its assigned IP address.
4. Function is erratic. Appears to periodically reset.
POSSIBLE REASONS/SOLUTIONS:
1. Incorrect network configuration may cause the MCR to
receive a fallback IP address or perform soft restarts. Verify that the IP address is correct. If you manually enter (or DHCP assigns) an IP address that already exists on the network, this will create a conflict. The MCR will reset its address (fallback) to one within the link-local address space. Determine the cause of the fallback IP address and resolve the issue.
2. View the error status field at the bottom of the “MCR
Status” window for messages.
3. When the Ethernet interface is initialized the network
device will verify that the IP address (either static or assigned by DHCP) is not being used by another device on the network. If a conflict is found the NTD clock will default to a 169.254.xxx.xxx address. The IP address that caused the error is saved and returned as an error to WinDiscovery. This error status is available to the user via the Status window on WinDiscovery.
4. If static IP addressing is being used the original conflicting
static IP address can be restored by doing a soft restart of the device using either WinDiscovery or Telnet prior to changing any other configuration parameters.
5. The DHCP is selected, but the MCR keeps falling back to
the 169.254.xxx.xxx address because the Ethernet interface keeps reinitializing. Once the MCR is successfully communicating with a DHCP server, the reinitializing will cease. Careful: if a discovery is performed while these fallbacks are occurring reinitialization could be delayed by two hours.

Note: For security purposes, the Telnet interface can be disabled. When disabled, you will no longer be able to access the unit with Telnet. To re-enable the Telnet feature, one of the other configuration methods must be used, or the unit must be reset to factory default configuration.
PROBLEM:
MCR1000 appears to ‘reset’ periodically.
POSSIBLE REASONS/SOLUTIONS:
1. Check the network connection and setup. If DHCP is
enabled and a DHCP server is not active on the network the clock will hesitate periodically while attempting to resolve DHCP configuration. To correct the problem, switch to manual networking configuration (set a Static IP address) or determine why the local DHCP server is not operating.
2. If the MCR1000 cannot resolve its DHCP address in DHCP
mode the MCR1000 will periodically perform a soft restart to reinitialize its communication port and DHCP configuration.
3. If the MCR1000 has not been configured with at least
one valid DNS server (or that DNS server is down) hesitations similar to those described in #1 will occur. At least one valid DNS server is required for operation.
PROBLEM:
MCR1000 Unable to communicate with Telnet.
POSSIBLE REASONS/SOLUTIONS:
1. If the MCR1000 has been configured to use DHCP for
network configuration, but no DHCP/BOOTP server is present, the MCR1000 may not respond to discovery requests for up to twenty seconds after power-on.
2. Verify that you have the correct IP address for the unit
and the IP address did not change. If using DHCP to provide the IP address, this address may change periodically, you must know the IP address of the unit to use the TELNET interface.
3. Verify that the MCR1000 does not have the Telnet
interface disabled.

See the knowledgebase articles at the Microsoft website regarding using the Windows W32Time service (built in NTP/SNTP time client for the XP/2003 Servers).
PROBLEM:
NTP/SNTP client is unable to communicate with the MCR1000
POSSIBLE REASONS/SOLUTIONS:
1. Verify that the MCR1000 is attached to the network.
2. Verify that all network cables, hubs, etc. are in proper
working order. Be sure that Ethernet crossover cables are not being used where inappropriate.
3. Verify that the MCR1000 is actually reachable from the
client. Try “pinging” the IP address of the MCR1000. If this fails, it is possible that the MCR1000 has an invalid network configuration or that the network is down. Consult your network administrator for assistance.
4. Verify that the MCR1000 is set to output if operating in
internal oscillator/real time clock mode and that the maximum time difference has not been exceeded.
5. Verify that the client is not using “Symmetric Active”
mode. The MCR1000 does not use Authentication and will not work with NTP/SNTP clients in a “Symmetric Active” mode.
PROBLEM:
The NTP client indicates that the MCR1000 is providing invalid time, or has flagged time as invalid.
POSSIBLE REASONS/SOLUTIONS:
1. The MCR1000 will always answer NTP requests (unless
the client is set to use symmetric active mode). The MCR1000 will flag time as invalid if it does not have trusted time to distribute. This may occur temporarily during GPS navigation state changes or before the first GPS acquisition during an MCR1000 power up following a long period without power.
2. By default, the MCR1000 will begin flagging time invalid
after 24 hours of consecutive GPS acquisition failure or non-operation (i.e. power off). This is a protective feature. It can be adjusted or disabled if desired.

PROBLEM:
The UTC date and time are incorrect and the MCR1000 does not retain time settings when powered down or up.
POSSIBLE REASONS/SOLUTIONS:
The MCR1000 maintains its internal time in battery-backed memory located using a Real Time Clock (RTC). The battery supplies power, up to 24 hours, to the TCXO 32kHz oscillator and RTC when the unit is powered off. This allows the internal configuration to be maintained and the time and date to continue to increment. So, if there is a problem here, the internal battery likely needs replacement.
The battery type is a “maintenance free” 3V rechargeable
magnesium lithium battery. It can be replaced by a qualified technician. Or the unit can be sent to technical support at Masterclock.
See the “Specifications” section (page 51) for details on the recommended battery replacement, or contact technical support for assistance.
PROBLEM:
Lost password.
POSSIBLE REASONS/SOLUTIONS:
Your custom password cannot be recovered if it is lost. Reset the MCR1000 to the factory default configuration (see page
6). Under factory defaults the MCR1000 will need to be
reconfigured to your custom settings.
The factory - default password is “public”.

PROBLEM:
Multiple error windows titled, “Bad Password,” continue to pop-up each time a configuration setting is applied.
POSSIBLE REASONS/SOLUTIONS:
1. You have entered and “remembered” an incorrect
password in the password windows. You must clear the memorized password using one of the two options below.
2. WinDiscovery only remembers the password for the
current session, so close the WinDiscovery session and reopen it. All passwords will be forgotten and you can start anew.
3. As an alternative to closing your WinDiscovery session,
right click on the device in the left WinDiscovery window. The last entry in the pop-up menu lists “Forget Memorized Password.” Select this option.
4. You are using a global password that is different from the
password of the MCR1000 you are trying to administer. Change the global password to match that of the MCR1000, or change the unit password to the global password.
