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.

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 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.

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.

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 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.

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 TimeLord Master Clock is fitted as standard with one  
RS232 & RS485/RS422 serial data output. The signals are  
accessed via the female DB9 connector labelled RS232/RS485  
S1 mounted on the rear of the unit.

The TimeLord is optionally available with two or four RS232/RS485  
serial data outputs. Where installed, these signals are  
accessed via the S2, S3 and S4 female DB9 connectors. If your  
TimeLord is fitted with multiple serial ports, extra serial setting  
modes (S2, S3 & S4) will appear in the main programming  
menu to allow these ports to be individually configured using  
the procedure detailed below. (Please note: The RS232 level 1  
pulse per second output is not present on pin1 of serial ports  
S3 & S4).

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.  
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  
IP Address  
This is the Internet Protocol address that the  
4860net uses on the computer network.  
Sb  
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.  
Gt  
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  
3278898625  
nLoc  
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.  
bcASt  
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.

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  
organisations 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 As 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.

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 1st 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.

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.  
0
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.  
1
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  
3if 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.  
1)  
2)  
3)  
4)  
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).  
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.  
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.  
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.  
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.  
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.  
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.

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.

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.

This procedure enables the master clock to know what time the  
slave clocks are displaying and thus calculate the required  
number of catch-up pulses. It also ensures that the correct  
type of impulses are output. This procedure must be

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.

The use of twin 1.5mm2 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 (1.5mm2 Pirelli  
PSX).  
Unscreened data cables should not be run in proximity to  
power cables supplying fluorescent lighting or other sources of  
electrical noise.  
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.

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.

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.
