Frequently Asked Questions

TimeLord Master Clocks

Operating and Installation Instructions

Will the V-488C / V-488B GPS receiver system work
indoors?

Both the V-488C and the V-488B GPS receiver systems are
designed for external mounting. We would recommend
positioning the post-mounting V-488C GPS system on the roof
of the building with a clear view of at least 75% of the sky.

The post mounting antenna supplied with the V-488B GPS
system should be mounted in a similar position. The decoder
box supplied with the V-488B GPS system should be mounted
within 5 metres of this (either indoors or outdoors).

Please refer to chapter 5 for further information.

Can I extend the cable supplied with the V-488C GPS
receiver system?

The system is supplied with 25 metres of four-core screened
cable for connection between the V-488C GPS system and the
TimeLord master clock. This cable length may be increased
up to a maximum of 50 metres using a similar type of cable or
up to a maximum of 200 metres using a heavier gauge cable.

Please refer to chapter 5 and appendix A for further
information.

Can I extend the cables supplied with the V-488B GPS
receiver system?

The V-488B GPS receiver system is supplied with a 5 metre fixed
length of cable for connection between the post-mount
antenna and the decoder box. This cable length cannot be
adjusted.

The system is also supplied with 25 metres of four-core
screened cable for connection between the decoder box and
the TimeLord master clock. This cable length may be
increased up to a maximum of 50 metres using a similar type
of cable or up to a maximum of 200 metres using a heavier
gauge cable.

Please refer to chapter 5 and appendix A for further
information.

The V-484.06 MSF and V-484.07 DCF radio time code receivers are
suitable for indoor use only.

Please refer to page 5-3 for further information.

Can I extend the cable to my V-484 series radio time
code receiver?

The cable connection to a V-484 series radio time code receiver
may be extended up to a maximum of 10m using a similar
specification cable. This connection may be extended up to a
maximum of 200 metres using a screened twisted pair cable
as specified in appendix A.

How can I tell if the TimeLord master clock has
synchronised to my chosen synchronisation time
source?

When the TimeLord master clock is synchronised, the ‘Lock’
LED will illuminate.

Why does the master clock not show the correct time,
even though the ‘lock’ LED is illuminated?

Check that the location is set correctly. Please refer to chapter
4 for further details.

How do I synchronise / time-stamp a CCTV device from
the TimeLord master clock?

Appendix C lists the supported devices and any relevant
application note. The application notes detail how to connect
the TimeLord master clock to your chosen device and may be
found on the CD-ROM supplied.

How do I connect analogue impulse clocks to the
TimeLord master clock equipped with the -02 O/P option?

Please refer to chapter 12 for details on impulse output setup.

Why will the TimeLord master clock not synchronise
to the MSF or DCF radio time code signal?

Under normal circumstances the MSF signal provides reliable
operation at distances of up to 1000km from Rugby in the
United Kingdom. The DCF signal is normally usable up to
1500km from Frankfurt in Germany.

In good conditions the TimeLord master clock, when used
with a V-484 series radio time code receiver should synchronise
to MSF or DCF within 3 minutes. During this period, the ‘code’
LED should flash once per second.

However, MSF and DCF suffer greatly from electromagnetic
interference which can cause the TimeLord master clock not
to synchronise. In this instance, the ‘code’ LED on the front
panel of the TimeLord may flash erratically. To minimise
interference problems, we would recommend mounting the
V-484 series radio time code receiver away from any computer or
electronic equipment, fluorescent lighting, lift equipment,
metal girders, reinforced concrete walls or any other sources of
electrical noise.

MSF is off-air for a maintenance period of two weeks during
the summer, and the first Tuesday of every January, April, July
and October. Please refer to page 5-3 for further information.

Will the V-484 series radio time code receiver work
indoors?

The V-484.02 MSF and 484.03 DCF radio time code receivers are
suitable for either indoor or protected outdoor mounting. For
reliable operation, we would recommend mounting these units
externally if possible though they normally work indoors also.

Leap Second Insertion

The TimeLord can be programmed to allow for leap second
insertion (one second is sometimes added at the end of March,
June, September or December), to compensate for the
deceleration of the Earth’s rotational time with respect to the
the Atomic clock (UTC).

This function is enabled by programming the ‘LS’ setting to yes
(as shown on page 2-6).

supply voltage label fixed to the rear of the clock (rackmount
versions) or on the external power supply (desktop).

A connection to the earth line must be made to ensure safe
operation and ensure compliance with EMC regulations.

To ensure conformance with EN60950:
(A) For installations where the TimeLord master clock

is to be permanently connected into the mains
power circuit, a readily accessible disconnect device
should be incorporated in the fixed wiring.

(B ) For installations where the TimeLord master clock

is to be plugged into the mains power circuit, a
socketed outlet should be installed near the
equipment and should be easily accessible.

All installation work should be performed in accordance
with the Sixteenth Edition of the IEE Wiring Regulations.

Battery backup.

Expandable TimeLords are fitted with a Lithium battery which will
maintain the internal time count for a period normally in excess of
1 year if the mains supply is interrupted.

The TimeLord-Lite is fitted with an automatically recharging battery
which will, when fully charged, maintain the internal time
count for a period in excess of 50 hours if the mains supply is
interrupted.

Fuses and Output protection.

The TimeLord circuit board makes use of advanced automatically
resettable fuse technology so that it is protected under fault
conditions.

The universal power supply within the TimeLord uses a
20mm fuse rated at 2 Amps 250V. Please note that this fuse is
not a user serviceable part.

External Connections

The external connections located on the rear of the TimeLord
provide the following inputs and outputs:

Operating and Installation Instructions

4 - Location Setup

The TimeLord Master Clock provides advanced time zone
functionality. Regardless of time synchronisation source, the
TimeLord can be used to provide time and date information
referenced to UTC, user ‘local’ time or other custom time zone.
Incorporating ‘Set Once’ technology, the TimeLord will
automatically calculate future seasonal time changes for all 64
of the preset time location code settings.

Setting the location

For installations where the output of the TimeLord is to be
referenced to UTC / GMT, the location code should be set to 00.
For installations where the output of the TimeLord is to be
referenced to the ‘local’ time zone, select the appropriate
location code from the table opposite. (eg. For a unit installed
in Birmingham, England, where ‘local’ time output is required,
location code 01 should be used.)

User Programmable Time Zone

For time-offsets and daylight saving time change dates not
covered by the location codes on page 4-2, a user
programmable time zone is provided. Information regarding
the time offset from UTC and any daylight saving change rules
may be input via a 12 digit code.

Please contact our technical department for further information
regarding this function.

GPS Synchronisation

The V-488C and V-488B GPS receiver systems are designed to be
automatically synchronised to time signals transmitted from
the Global Positioning System (GPS) navigation network. The
GPS constellation consists of 28 operational satellites,
operating in 12 hour orbits at an altitude of 20,200km.

Both the V-488C and the V-488B GPS receiver have been designed
for simple installation and operation by the end-user, requiring
only a 4 wire interconnection to the TimeLord Master Clock.
When synchronised to a V-488C or 488B GPS receiver system the
TimeLord-Net Master Clock output signals are maintained within
50uS of UTC (100uS of UTC on TimeLord-Lite versions).

The reception gain pattern of both GPS systems is designed
for full, upper hemispherical coverage with the gain
diminishing at low elevations. This cross-section is consistent
through 360 degrees and so the 3 dimensional gain pattern is
a symmetrical spheroid surface.

Advantages of GPS time synchronisation:

• Very accurate synchronisation

• Can be used anywhere in the world

• Not subject to EM interference
Disadvantages of GPS time synchronisation:

• Antenna needs to be mounted externally with a clear
view of 75% of the sky.

The V-488C GPS Synchronisation System

The V-488C GPS synchronisation system is housed in a single
IP66 rated case containing an advanced combined Sony active
antenna and 12 channel parallel GPS receiver module and a
microprocessor based communications interface. The system
is supplied complete with a post mounting clamp to enable
the unit to be fixed to a suitable horizontal or vertical post of
up to 2cm diameter. The antenna should be mounted on the
roof of a building or under a suitable skylight.

module via a single 5 metre long RG58 coaxial cable. A post
mounting clamp is supplied to enable the antenna to be fixed to
a suitable horizontal or vertical post of up to 2cm diameter. The
antenna may be mounted on the roof of a building or under a
suitable skylight.

The GPS receiver/decoder unit contains a Motorola 8 Channel
parallel receiver and a microprocessor based communications
interface. The receiver/decoder module is housed in a robust
aluminium case fitted with mounting points for wall mounting
and protected to IP65. The module should be mounted in a
protected location within 5 metres of the antenna.

TimeLord Master Clocks

Operating and Installation Instructions

MSF and DCF synchronisation

MSF and DCF are the two most widely used radio time code
signals. The DCF signal is derived from the atomic clocks at the
Physics Institute of Brunswick and transmitted at a frequency
of 77.5KHz from Manflingen, near Frankfurt in Germany. The
MSF signal is referenced to the Caesium Beam Oscillators at
the National Physical Laboratory and transmitted on a
frequency of 60KHz from Rugby in the United Kingdom.

Under normal circumstances the DCF signal provides reliable
operation at distances of up to 1500km, MSF signals are
normally usable up to 1000km from the transmitter. Greater
operating ranges are possible at night.

When synchronised to MSF or DCF using a V-484 radio receiver
the TimeLord Master Clock output signals are maintained
within 30mS of UTC.

Advantages of MSF and DCF time synchronisation:

• Lower purchase cost than GPS

• Can sometimes be installed internally.
Disadvantages of MSF and DCF time synchronisation:

• Can be difficult to find good location for signal
reception.

• Suffers greatly from EM interference - Avoid locating
near computers, electronic equipment, fluorescent
lighting, lift equipment, metal girders, reinforced
concrete walls and all other sources of electrical noise.

• MSF is off-air for a maintenance period of two weeks
during the summer, and the first Tuesday of every
January, April, July and October. MSF status can be
checked by telephoning 020 8943 6493.

Installation

The V-484 series time code receiver should be mounted:

• At least 2.5 metres from the TimeLord Master Clock.

• At greatest practical distance from:
Other electronic equipment including computers,
fluorescent lights and signs, metal girders, reinforced
concrete walls and any other sources of electrical noise.

• O n the side of the building nearest Rugby (MSF) or
Frankfurt (DCF).

• Preferably on the outside of the building (V-484.02 and
V-484.03 only) as high as possible. The case is
weatherproof to IP65 (484.02 and 484.03 only) but it is
preferable to provide some protection from direct rain.

• With the cable entry on the lower face of the case.
(V-484.02 and V-484.03 only)

The antenna is supplied with 5 metres of two core cable, if a
longer cable distance is required Appendix A should be consulted
for suitable cable specifications. The maximum distance
between the V-484 radio receiver and the TimeLord Master
Clock is 200m.

If a screened cable is used, the cable screen should be connected
to the EMC grounding terminal on the 10 way terminal block,
located on the rear of the TimeLord.

Alignment

The V-484.02 (MSF) and V-484.03 (DCF) radio receivers have dual
ferrite antennas, which normally permit location regardless of
orientation to the transmitter. The receiver is mounted by means
of four fixing holes in the rear surface which are accessed after
removing the front cover. The four mounting holes are located
outside of the central sealed compartment.

The V-484.06 (MSF) and V-484.07 (DCF) receivers have a single
antenna element and are supplied with an adjustable
mounting bracket so that the installer can ensure that the
orientation of the longest face of the receiver is at 90

o

to the

direction of the transmitter.

Press ‘^’ to save synchronisation mode
and return to normal time display.

Normal time display.

The front cover of the V-484.02 and V-484.03 receivers may be
removed to enable the indicator LED to be viewed. The indicator
LED on the V-484.06 and V-484.07 receiver is located on the front
face of the unit.

The alignment of the receiver is correct when the LED flashes
once per second. The Code LED located on the front of the
TimeLord will flash at the same time as the LED in the V-484.

Signal reception

In good conditions the TimeLord master clock will take three
minutes to synchronise with the transmitted time code from
either DCF or MSF. When the TimeLord is ‘locked’ to the
transmitted signal, the locked LED, located after the seconds
display, is illuminated continuously. During periods of signal
failure or signal corruption the clock will maintain timekeeping
using its internal crystal oscillator.

1 PPS / Serial ASCII Synchronisation

Special order versions of the TimeLord Master Clock are available
to facilitate synchronisation with an RS232 / RS485 level serial
ASCII data string or timebase generation from an RS232 /
RS485 level 1 Pulse Per Second source. The Serial variant will
synchronise to Serial format 1 (as shown on page 7.1)
transmitted at 9600 baud, 8 data bits, no parity, 1 stop bit at a
1 second repetition rate.

The serial messages numbered from 01 to 09 are user
programmable. This allows the user to program information
concerning the baud rate, data bits, parity, stop bits and serial
repetition to ensure that the format chosen meets their
requirements.

Some of the other serial data messages have factory preset
transmission formats to ensure that system interconnection is
trouble free.

C Common
Note:

The relay is configured so that
contacts no-C are normally open and
contacts nc-C are normally closed.

For example, if the relay is set to
close every hour for 100ms, contacts
no-C will close for 100ms on the hour,
while contacts nc-C will open for
100mS.

Operation

The relay can be programmed to operate every 5 seconds,
every minute, every hour, once per day at a user programmable
time or to signal a fault condition.

The relay contacts are rated for 500mA @ 30v DC operation.
The minimum contact load is 1mA @ 5v DC. The contact
closure duration is 100mS.

Normal time display.

Function ‘Time Setting Mode’. Press ‘+’

Function ‘Relay Setting Mode’.
Press ‘^’ to select.

If your

TimeLord
is fitted
with NTP,
EBU, S2, S4
or .IMP
options, you
may need to
press the ‘+’

Setting the Programmable Relay Time

When the TimeLord is used to provide one contact closure
per day it is recommended that the time chosen is at 03:00.
This allows the synchronised equipment to be adjusted for the
seasonal time change on the day that it occurs. Most
conventional systems use a contact closure at 00:00 which will
not update the synchronised equipment for the seasonal time
change until the next day.

TimeLord-Net Network Interface

RJ45 10Base-T Ethernet Connector
DB9 Network software update port
Link Link LED indicating connection to network
Data Data LED indicating data on the network

Operation

The TimeLord-Net operates as a Network Time Server on a TCP/IP
Computer network. The quick setup procedure should be
followed to get the TimeLord-Net up and running quickly. Page 9-3
details the various protocols that the TimeLord-Net supports while
pages 9-1 and 9-2 detail the basics behind IP addresses,
subnets and gateways.

Pages 9-4 and 9-5 show the setting procedure in more detail.
The TimeLord-Net master clock has a 10Base-T Ethernet interface

and must be connected either to a dedicated 10Base-T port or
a switchable 10Base-T / 100Base-T port on your network.

Net Update

Quick Setup

Install the TimeLord-Net as detailed in section 3 of this manual.

Attention: If you are unsure of the following network

settings please contact your network administrator.

Incorrect settings can adversely affect the

performance of your network.

1) Program the IP address of the TimeLord-Net in dotted­decimal notation. (e.g. 192.168.0.41) Use the plus and
minus buttons to increment and decrement each value.
The up arrow will move on to the next value, the down
arrow will return to the previous value.

2) Program the Subnet Mask of the TimeLord-Net in dotted­decimal notation. (e.g. 255.255.255.0) Use the plus
and minus buttons to increment and decrement each
value. The up arrow will move on to the next value, the
down arrow will return to the previous value.

3) Program the default Gateway of TimeLord-Net in dotted­decimal notation. (e.g. 192.168.0.1). Use the plus and
minus buttons to increment and decrement each value.
The up arrow will move on to the next value, the down
arrow will return to the previous value.

4) Use the CAT5 patch cable (supplied) to connect the
TimeLord-Net to your TCP/IP Computer network. Ensure
that the network connection used is compatible with
10Base-T. Check the green link led illuminates,
confirming that correct connection has been made to
the network.

TCP/IP Concepts
IP Address

TCP/IP is todays most prevalent networking technology. It can
be used for small Local Area Networks (LAN) of two or three
users, right through to the other end of the spectrum where it
is used as the protocol connecting every machine on the

elbaTsgnitteSkrowteN

Internet.
Each connected computer must have a unique address to

ensure that data transmitted from one location reaches the

Blocks of addresses are assigned to organizations by the
Internet Assigned Numbers Authority (IANA). Users and small
organisations usually obtain their addresses from their Internet
Service Provider while larger organisations liaise directly with
the IANA.

The Internet Protocol (IP) uses 32 bit addresses, which when
displayed to humans are usually written in dotted-decimal
notation. Dotted-decimal notation is where the address is
written as four decimal numbers, one for each byte of the
address.

For example the dotted-decimal IP address 195.112.5.193 can
be represented in the following formats:

Decimal representation: 3278898625
Hexadecimal representation: 0xC37005C1
Binary representation: 11000011 01110000

00000101 11000001

The IP address of a computer is constructed of two parts. The
first part of the address identifies the network to which the
computer or host is connected, the second part specifies the
actual host itself. The TCP/IP software on each host can
automatically determine the class of an IP address by
examining the first byte of that address.

There are five different classes of address:

Class A - 1.x.x.x - 126.x.x.x

These addresses have a 8 bit network number and a 24 bit
host number addresses. Each class A network can have
16,777,214 hosts.

Class B - 128.1.x.x - 191.254.x.x

These addresses have a 16 bit network number and a 16 bit
host addresses. This means that each class B network can have
65,354 hosts.

Class C - 192.0.1.x - 223.255.254.x

These addresses have a 24 bit network number and an 8 bit
host addresses. This means that each class C network can
have 254 hosts.

Class D - 224.0.0.0 - 239.255.255.255

Class D network addresses are used for multicasting, which is
where information sent from one address can be sent to many
different hosts simultaneously.

Class E - 240.0.0.0 - 254.255.255.255

Class E network addresses are used for experimental
purposes.

For each unique network number, the base address of the
range (i.e. host number zero) is known as the network address
and is not assigned to a host. The top address of the range is
(i.e. host number set to all ones) the broadcast address which
is used as the address for sending to all hosts on the same
network number simultaneously.

Subnet Addressing

Subnet addressing allows us to split one IP network address
into several smaller physical networks known as subnets. This
is especially useful with Class A and Class B addresses where
there are very large numbers of network hosts with the same
network address.

A subnet is created by splitting the host address part of the IP
address into two, the first being subnet address and the
second host ID.

stib41stib8

BssalC10 krowteNtenbuStsoH

In the class B example shown above the address has been
subnetted into 254 subnets, each with a possible 254 hosts.

Subnet Mask

The subnet mask is a 32 bit number which specifies how many
bits of the IP address are for the network / subnet address and
how many are for the host address.

stib8

For the class B subnet example used above the subnet mask
would be as follows:

stib42

BssalC11111111111111111111111100000000

The following table details a few typical subnet masks and the
network classes / subnets they describe.

Private IP addresses

With the massive growth of the Internet there was a real
danger that the IANA would run out of IP addresses. To avoid
this situation three blocks of IP addresses have been reserved
for use in private networks. It is recommended that on an
organisation’s TCP/IP networks use these private network
numbers for their networks and make use of a technology like
NAT (Network Address Translation) to allow their users access
to the Internet.

10.0.0.0 - 10.255.255.255

172.16.0.0 - 172.31.255.255

192.168.0.0 - 192.168.255.255

ARP & MAC

When one device (A) wants to send data to another device (B)
on the same Ethernet LAN it must convert the IP address of the
destination device to the Ethernet Media Access Control (MAC)
address of that device. Each Ethernet device has a globally
unique 48 bit MAC address which is assigned at time of
manufacture.

If device A does not have B’s MAC address an Address
Resolution Protocol (ARP) request is broadcast onto the local
Network. The ARP request contains the IP address of device B,
so device B is the only device to respond. Device B sends its
MAC address to device A and it is stored in device A’s ARP
table.
Device A can now send data directly to device B.

Gateway Address

The gateway address is used when a device on a network
sends data to another device that is connected to a different
network segment. The gateway device is typically a router
connecting two different networks together.

When one device sends data to another device the TCP/IP
software checks to see if the destination network address is
the same as its own network address. If the network address
is the same the data is transmitted normally, using ARP to
resolve the destination MAC address if required.

If the network address is different the data is forwarded to the
IP address specified in the ‘Gateway’ setting for routing
onwards to the specified network. This routing process may
occur several times as the data travels across different
networks enroute to its destination.

Supported Protocols
Time Protocol (RFC868)

RFC868 defines the original TIME protocol, which provides site­independent, machine-readable date and time in response to
a request from a client PC.

When a request is received the TimeLord-Net responds with a 32-bit
time value corresponding to the number of seconds since
midnight of January 1

st

1900. This representation of time will

serve until the year 2036.
Time Protocol is supported in the UDP mode of operation.

(RFC868)

NTP (RFC1305 & RFC1119)

The Network Time Protocol (NTP) is the most widely used
computer time synchronisation protocol in use today. It
provides a mechanism to both organise a synchronisation
subnet and distribute precise time synchronisation information
to the local clocks of all participating computers. In most parts
of the Internet today it is possible to use NTP to provide
accuracy’s of tens of milliseconds, depending on the
characteristics of the synchronisation source, stratum of
operation, the local network paths and the client software
used.

The NTP standard has been designed so that it can provide
reliable operation with clients and servers of vastly different
specifications and across network paths with diverse delay and
jitter characteristics. Most users of Internet NTP
synchronisation make use of the standard NTP distribution
available from http://www.ntp.org. This software package
includes the full suite of NTP options and algorithms and has
been ported to a wide variety of hardware platforms ranging
from Personal Computers (PC’s) to supercomputers.

We would recommend that, in large hierarchical time
distribution projects, the standard NTP distribution be used on
the Stratum 2 and 3 servers for maximum redundancy and
client availability.

Network Time Protocol (NTP) v2, v3 and v4 clients are
supported in both unicast and broadcast modes of operation.
(RFC1305 & RFC1119)

SNTP (RFC2030 & RFC1769)

Simple Network Time Protocol (SNTP) v3 and v4 clients are
supported in both unicast and broadcast modes of operation.
(RFC2030 & RFC1769)

Simple Network Time Protocol (SNTP) is an adaptation of NTP,
which can be used for applications where the ultimate
performance and associated overhead of the full NTP
implementation is not required.

Most PC client software is based on the SNTP specification and
certainly for most intranet applications will provide a higher
degree of accuracy than is required.

Simple Network Time Protocol (SNTP) v3 and v4 clients are
supported in both unicast and broadcast modes of operation.
(RFC2030 & RFC1769)

Synchronisation Alarm Status

The NTP/SNTP version 4 message format has provision for a
two-bit ‘Leap Indicator’ code that gives indication of an
impending leap second and synchronisation alarm status.
When ‘nLoc’ is set (y), the TimeLord-Net Master Clock will return an
LI (Leap Indicator) value of ‘0’ if the clock is synchronised and
‘3’ if the clock is unsynchronised. When ‘nLoc’ is not set (n), the
TimeLord-Net Master Clock will return an LI (Leap Indicator) value of
‘0’ regardless of synchronisation status.

If the synchronisation source is set to ‘none’ and ‘nLoc’ is set,
the TimeLord-Net will return an LI (Leap Indicator) value of ‘3’.

1KHz AM modulated balanced signal.

IRIG is a series of time codes originally developed in the 1940s
by the International Range Instrumentation Group (IRIG) for
recording time information on magnetic tape and wire for rocket
test range instrumentation purposes. IRIG-B code is normally
transmitted at a 100Hz bit rate, amplitude modulated on a 1KHz
carrier, where the amplitude of a ‘1’ bit is three times that of a
‘0’ bit.

Standard IRIG-B code contains day-of-year and hours, minutes
and seconds information, however a number of organisations
have added their own extensions to the standard format.
AFNOR NFS 87 500 timecode is a development of IRIG-B which is
widely used in Europe and contains additional day, day-of-month
and year information.

The IRIG output is available on the TimeLord-Lite and
TimeLord-Net / Net-Client versions.

12 - Impulse Output (V-02 Option)

V-02 .IMP Dual Impulse Output

6 way terminal block
Impulse 1 Impulse Channel 1

Impulse 2 Impulse Channel 2

Operation

The TimeLord master clock is optionally available with dual channel
24V alternate polarity impulse outputs (Option V-02).

Each output may be programmed by the user for one of a
number of different combinations of pulse length and
repetition rate to drive impulse slave clocks requiring one
second, half minute or one minute alternate polarity impulses.

The fully protected output drive circuits detect power failure
and short circuit line fault conditions which are automatically
corrected for on fault removal.

Automatic Correction

Automatic time correction following power failures, the
removal of fault conditions and after seasonal time changes is
carried out by increasing the pulse repetition rate or by
stopping the impulses depending on which action will result in
a shorter correction time.

In the 1 second - standard mode the system will take one hour
to correct for each hour that the slave clocks are behind the
master.

In the 1 second - slow correction mode the system will take
approximately one and a half hours to correct for each hour
that the slave clocks are behind the master.

The 1 second - seconds synchronisation only mode is intended
for use with 4 wire slave clocks requiring both minute and
second impulses.

Commissioning

Please perform the following four procedures to commission
your impulse clock system.

Setup Part A - Initial Setup Procedure

Before commencing this procedure, please ensure that all of
the clocks are displaying the same time.

1) Install the TimeLord master clock as detailed in section
3 of this manual.

2) Program the required location as detailed in section 4
of this manual.

3) Connect any synchronisation option as detailed in
section 5 of this manual.

4) Connect the analogue clocks to your chosen impulse
channel as shown on page 12-4. Please refer to
appendix A for recommended cable specifications.

5) For your chosen impulse channel, program the required
‘Impulse output type’. This is part of the impulse
channel setup procedure shown graphically on page
12-2. The ‘Impulse Output Type Table’ below details
the options available.

Setup Part B - Synchronisation of clocks

This procedure ensures that all clocks on your chosen impulse
channel are synchronised together. Before starting this
procedure you should ensure that all clocks are displaying the
same time.

6) Referring to the ‘starting the impulses’ procedure on
page 12-3, select the ‘pulse’ option and press the ‘^’
key. This action transmits a single pulse to all of the
connected clocks.

7) Now examine the slave clocks. Reverse the impulse
connections to all slave clocks that appear to have
‘missed’ a pulse and manually advance these clocks by
two impulses. All clocks connected to this channel
should now be in synchronisation.

Setup Part C - Programming the Impulse time

8) For your chosen impulse channel, program the ‘Impulse
Time’. This is part of the impulse channel setup
procedure shown graphically on page 12-2. The
‘Impulse Time’ is the time that the analogue clocks are
currently displaying. Please note that you must ensure
that all of the analogue clocks on your chosen impulse
channel are showing the same time.

Setup Part D - Starting the Impulses

9) Referring to the ‘starting the impulses’ procedure on
page 12-3, select the ‘run’ option and press the ‘^’ key
to exit.

The channel will now be running and the master clock will
calculate whether it will be quicker to output catch-up
impulses or wait for the current time to reach the impulse time
(as previously programmed).

Visual Indication of Operation and Error status

The TimeLord.IMP master clock provides full time visual indication
of impulse channel operation and alarm status. When an
impulse is transmitted, the relevant channel LED will illuminate
below the time display on the front panel. If an overload or
short circuit line fault occurs, the impulse alarm LED will flash
along with the relevant channel LED.

The current impulse time of channels 1 and 2 may be
examined by pressing the ‘+’ key three or four times
respectively when on the standard time display.

Please refer to page 12-3 for further details.

The cable length may be extended to 10m using unscreened
cable, RS 367-943 - 22 awg or equivalent. In areas of high
electrical noise a screened twisted pair should be used. The
cable screen should be grounded at the TimeLord end only.

Cable length may be extended to 200m using a screened
twisted pair cable, RS 368-340 - 22 awg or equivalent. (UL
style 2092, Alpha 2401)

For screened LSOH (Low Smoke Zero Halogen) applications RS
362-140 (two pairs 7/0.25 - 22 awg) may be used. Equivalent
to UL style 2493.

TimeLord -> Digital Displays w482 code interconnection

The w482 time code system is designed to have considerable
immunity to external electrical interference and screened cable
is only required in areas of high electrical noise.

If in doubt one should always consider the use of the next
heavier gauge cable as this invariably increases system
integrity at minimal additional system cost and allows for
future system expansion.

All installation work should be performed in accordance with
current Building Regulations and the Sixteenth Edition of the
IEE Wiring Regulations, or equivalent local regulations.

TimeLord -> Analogue Impulse Clock interconnection

Cabling for analogue clock systems is highly dependent on the
number of clocks, power consumption of the clock movements
and distance of cable involved.

Based on the use of 10mA clock movements, each channel of
the TimeLord.IMP master clock could drive 20 clocks (a total of
40 clocks). Alternatively, each channel of the TimeLord.IMP could
drive 25x 8mA clock movements (a total of 50 clocks).

TimeLord -> Analogue Clocks (with hands) connections

Normal installations may use standard mains cable. (e.g. twin

2

1.5mm

) The size of the cable depends on the overall cable

length, the number of clocks and their spacing on the cable.
The use of twin 1.5mm

2

cable will be adequate for installations
of up to 50 clocks, calendar clocks or time-zone displays using
up to 1km of cable. For LSOH applications low smoke cable to
IEC332 and BS4066 may be used. RS212-7882 (1.5mm

Operation

The Network Time Protocol (NTP) synchronisation option
enables the TimeLord-Net-Client to synchronise to an NTP time
source on a TCP/IP Computer network. The quick setup procedure
should be followed to get the TimeLord-Net-Client up and running
quickly. With NTP selected as the synchronisation source, a
reduced set of options will appear in the Network Setting
menu as detailed in the NTP Network Settings Table below.

Please refer to chapter 9 for further information regarding TCP/
IP concepts and NTP. Please note that the TimeLord-Net-Client
cannot operate as a Network Time Server.

The TimLord-Net Client has a 10Base-T Ethernet
interface and must be connected either to a dedicated 10Base­T port or a switchable 10Base-T / 100Base-T port on your
network.

Quick Setup

Install the TimeLord-Net-Client as detailed in section 3 of this manual.

Attention: If you are unsure of the following network

settings please contact your network administrator.

Incorrect settings can adversely affect the

performance of your network.

1) Select ntP (NTP - Network Time Protocol) as the
synchronisation source in the ‘Synchronisation Mode’
menu. Please refer to chapter 5 for further details.

2) In the Network Setting menu, program the IP address
of the TimeLord-Net-Client in dotted-decimal notation. (e.g.

192.168.0.41) Use the plus and minus buttons to
increment and decrement each value. The up arrow will
move on to the next value, the down arrow will return
to the previous value. This procedure is shown
graphically on pages D-3 & D-4. Please refer to the
NTP Network Settings Table below and chapter 9 for
further information.

3) In the Network Setting menu, program the Subnet
Mask of the TimeLord-Net-Client in dotted-decimal notation.
(e.g. 255.255.255.0) Use the plus and minus buttons to
increment and decrement each value. The up arrow will
move on to the next value, the down arrow will return
to the previous value. This procedure is shown
graphically on pages D-3 & D-4. Please refer to the
NTP Network Settings Table below and chapter 9 for
further information.

4) In the Network Setting menu, program the default
Gateway of TimeLord-Net-Client in dotted-decimal notation.
(e.g. 192.168.0.1). Use the plus and minus buttons to
increment and decrement each value. The up arrow will
move on to the next value, the down arrow will return
to the previous value. This procedure is shown
graphically on pages D-3 & D-4. Please refer to the
NTP Network Settings Table below and chapter 9 for
further information.

5) In the Network Setting menu, program the IP address
of the NTP time server in dotted-decimal notation. (e.g.

192.168.0.41) Use the plus and minus buttons to
increment and decrement each value. The up arrow will
move on to the next value, the down arrow will return
to the previous value. This procedure is shown
graphically on pages D-3 & D-4. Please refer to the
NTP Network Settings Table below and chapter 9 for
further information.

6) Having returned to the time screen, cycle the power on
the TimeLord-Net-Client Master Clock.

7) Manually set on the time on the TimeLord-Net-Client Master
Clock to within half an hour of the real time (please
refer to page 2-4 for further details of this procedure).

8) Use the CAT5 patch cable (supplied) to connect the
TimeLord-Net-Client to your computer network. Ensure that
the network connection used is compatible with
10Base-T. Check the green link led illuminates,
confirming that correct connection has been made to
the network.
