The V-484.06 MSF and V-484.07 DCF radio time code receivers are

suitable for indoor use only.

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.

Please refer to page 5-3 for further information.

Ca n I e xt e n d t h e ca b le t o m y V-484 se rie s ra d io t im e

co d e re ce ive r?

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).

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.

Please refer to chapter 5 for further information.

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.

When the TimeLord master clock is synchronised, the ‘Lock’

LED will illuminate.

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.

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.

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.

t o t h e MSF o r DCF ra d io t im e co d e sig n a l?

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 t h e V-484 se rie s ra d io t im e co d e re ce ive r w o rk

in d o o rs?

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.

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.

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).

Note:

A Screened cable should be used to

connect the V-488C / V-488B GPS receiver

to the TimeLord . The screen should

be connected to the EMC grounding

point on the TimeLord and on the

V-488B GPS receiver.

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.

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.

Normal time display

Under normal circumstances the DCF signal provides reliable

operation at distances of up to 1500km, MSF signals are

for suitable cable specifications. The maximum distance

between the V-484 radio receiver and the TimeLord Master

Clock is 200m.

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.

Sig n a l re ce p t io n

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.

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.

Alig n m e n t

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.

Special order versions of the TimeLord Master Clock are available

to facilitate synchronisation with an RS232 / RS485 level serial

1 second repetition rate.

The V-484.06 (MSF) and V-484.07 (DCF) receivers have a single

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.

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.

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.

TCP/IP Co n ce p t s

IP Ad d re ss

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

Internet.

Ne t w o rk Se t t in g s Ta b le

Each connected computer must have a unique address to

ensure that data transmitted from one location reaches the

correct destination.

Disp la y

Co d e

Se t t in g

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.

IP Address

This is the Internet Protocol address that the

4860net uses on the computer network.

Subnet Mask

The subnet mask when combined with the IP

address identifes the subnet (part of the bigger

network) that the TimeLord-Nete is connected to.

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.

Gateway Address

The gateway address is used by the TimeLord Net when

it needs to send information to computers and

devices which are connected to other networks

and subnets.

For example the dotted-decimal IP address 195.112.5.193 can

be represented in the following formats:

Decimal representation:

Hexadecimal representation: 0xC37005C1

Binary representation: 11000011 01110000

00000101 11000001

Synchronisation Alarm Status

This setting configures whether or not the NTP

packets will indicate an alarm state if the TimeLord-Net

is unsynchronised.

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.

NTP Broadcast

This setting configures whether or not the TimeLord-Net

will periodicaly broadcasts NTP time packets to the

local subnet. If enabled, NTP packets are

broadcast every 64 seconds.

255.255.255.0

Class C address with

no subnets or Class B

host number addresses. Each class A network can have

16,777,214 hosts.

Priva t e IP a d d re sse s

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

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.

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.

10.0.0.0 - 10.255.255.255

Class D - 224.0.0.0 - 239.255.255.255

172.16.0.0 - 172.31.255.255

192.168.0.0 - 192.168.255.255

Class D network addresses are used for multicasting, which is

where information sent from one address can be sent to many

different hosts simultaneously.

ARP & MAC

Class E - 240.0.0.0 - 254.255.255.255

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.

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.

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.

Su b n e t Ad d re ssin g

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.

Device A can now send data directly to device B.

Ga t e w a y Ad d re ss

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.

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.

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.

8 bits

Host

Subnet

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.

In the class B example shown above the address has been

subnetted into 254 subnets, each with a possible 254 hosts.

Su b n e t Ma sk

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.

Tim e Pro t o co l (RFC868)

RFC868 defines the original TIME protocol, which provides site-

independent, 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^st1900. 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)

NTP St ra t u m d e fin it io n s

St ra t u m

De fin it io n

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.

Unspecified or Unavailable

This stratum is used to describe the stratum level

of the orignal time signal source. In the case of

GPS the actual GPS signal from the satellites can

be viewed as stratum 0.

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.

Primary Reference Server

A server that derives its time from a external time

reference, e.g. GPS or radio time code, is defined

as a stratum 1 time server. Stratum time servers

are at the root of the synchronisation subnet.

The TimeLord-Net always operates as a primary

reference server at stratum 1.

Simple Network Time Protocol (SNTP) v3 and v4 clients are

supported in both unicast and broadcast modes of operation.

(RFC2030 & RFC1769)

Syn ch ro n isa t io n Ala rm St a t u s

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.

2-15

Secondary and Greater Stratum Time Servers

A client computer synchronised to a time server

operates at one stratum higher than the

synchronisation source.

Therefore if you have computers synchronised to

the TimeLord-Net that in their turn provide time to

other systems on your network the heiracy will be

as follows:

Stratum 1 - TimeLord-Net

Stratum 2 - Secondary time servers

Stratum 3 - Third level devices

If the synchronisation source is set to ‘none’ and ‘nLoc’ is set,

the TimeLord-Net will return an LI (Leap Indicator) value of ‘3’.

Before commencing this procedure, please ensure that all of

the clocks are displaying the same time.

Install the TimeLord master clock as detailed in section

3 of this manual.

Program the required location as detailed in section 4

of this manual.

Connect any synchronisation option as detailed in

section 5 of this manual.

Op e ra t io n

Connect the analogue clocks to your chosen impulse

channel as shown on page 12-4. Please refer to

appendix A for recommended cable specifications.

The TimeLord master clock is optionally available with dual channel

24V alternate polarity impulse outputs (Option V-02).

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.

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.

Se t u p Pa rt B - Syn ch ro n isa t io n o f clo cks

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.

Au t o m a t ic Co rre ct io n

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.

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.

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.

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.

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.

Se t u p Pa rt C - Pro g ra m m in g t h e Im p u lse t im e

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.

In areas of high electrical noise a screened twisted pair should

be used. The cable screen should be grounded at the TimeLord

end only by means of the rear grounding terminal.

Ap p e n d ix A - Ca b le Sp e cifica t io n s

Tim e Lo rd -> V-488B/C GPS in t e rco n n e ct io n

A suitable screened cable is RS 361-361, (twin 16/0.254 - 18

awg) equivalent to Alpha 2421, BICC H8093, UL style 2092

which is adequate for a spur controlling 25 clocks over a 1km

cable run or a greater number of clocks over a shorter distance.

The V-488B and V-488C GPS Receiver systems are supplied with

25 metres of four core 7/0.2 (0.22mm²) screened cable. The cable

screen should be grounded at the TimeLord end by means of

the EMC rear grounding terminal and on the V-488B GPS receiver

using the screw fitting provided.

For screened LSOH applications RS 362-140 (two pairs 7/0.25 -

22 awg) may be used. Two conductors may be connected in

parallel to provide a similar performance to 18 awg.

Equivalent to UL style 2493.

For distances of up to 50 metres the length can be extended by

adding an additional length of 7/0.2 cable. For greater

distances, up to a maximum of 200m, 16/0.2 (0.5mm²) cable

should be used.

For a Cat 5 installation, (24 awg) a single pair can be used to

connect up to 10 400A series clocks or time-zone displays at a

distance of up to 250m. For further distances or greater

numbers of clocks, additional cores should be paired together,

lowering the cable resistance.

Please note that the 5m cable which links the antenna to the

V-488BGPS Receiver cannot be extended.

of negligible resistance when compared to that of the cable used.

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.

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.

Tim e Lo rd -> Dig it a l Disp la ys w 482 co d e in t e rco n n e ct io n

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.

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.

Tim e Lo rd -> An a lo g u e Im p u lse Clo ck in t e rco n n e ct io n

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).

Tim e Lo rd -> An a lo g u e Clo cks (w it h h a n d s) co n n e ct io n s

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

1.5mm²) The size of the cable depends on the overall cable

length, the number of clocks and their spacing on the cable.

up to 1km of cable. For LSOH applications low smoke cable to

IEC332 and BS4066 may be used. RS212-7882 (1.5mm²Pirelli

Unscreened data cables should not be run in proximity to

power cables supplying fluorescent lighting or other sources of

Note: The above data assumes that all cable interconnections are

of negligible resistance when compared to that of the cable used

and the impulse clock movements draw 10mA each.

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

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.

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.

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.

The TimLord-Net Client 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.

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.

refer to page 2-4 for further details of this procedure).

IP Address

This is the Internet Protocol address that the

TimeLord-Net uses on the computer network.

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.

Subnet Mask

The subnet mask when combined with the IP

address identifes the subnet (part of the bigger

network) that the TimeLord-Net is connected to.

Gateway Address

The gateway address is used by the 4860net when

it needs to send information to computers and

devices which are connected to other networks

and subnets.

NTP Server IP Address

This is the Internet Protocol address of the NTP

time server that the TimeLord-Net-Client uses as its Time

Source.
