Frequently Asked Questions

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.

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.

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.

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.

The V-488B GPS Synchronisation System

The V-488B GPS receiver system comprises a post mounting active antenna and a separate receiver/decoder unit. The antenna module transmits the received GPS signals and receives power (5Vdc @ 25mA) from the GPS receiver/decoder 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.

V-488C and V-488B System Installation

To ensure ease of operation and to remove the possibility of operator error, both the V-488C and V-488B GPS systems are designed to self initialise.

Ensure that the TimeLord is disconnected from the mains power supply when making connections to the

V-488C / V-488B GPS receiver systems.

Install the V-488C unit or V-488B antenna module horizontally using the post mounting kit provided.

Ensure that the unit has a clear view of at least 75% of the sky. If the sky view is reduced the interval between

‘switch-on’ and system time synchronisation will be considerably increased.

Connect the antenna module to the GPS receiver using the special 5m cable provided (V-488B systems only).

Issue 2.0

Both the V-488C and the V-488B GPS Receiver systems are supplied with 25 metres of 4 core cable. Cable distance can be extended up to a maximum distance of 200 metres using the cable specifications detailed in appendix A.

Appendix A should be consulted for suitable cable specifications. The maximum distance between the

GPS system and the TimeLord master clock is 200m.

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

On 488B systems, the screen should be connected to the screw fitting on the 488B receiver/decoder case.

The screen is supplied pre-connected on V-488C units with captive cable connections.

The 4 GPS input connections located on the 10 way terminal block on the rear of the TimeLord, should be wired as shown in the diagram on page 5.1.

Connect the power supply to the TimeLord Master

Clock.

Once the power has been applied the receiver will automatically begin to search the sky for all available satellites, during this process the green LED will flash.

After three satellites have been acquired the green LED will stop flashing and become constantly illuminated, indicating that a precise date and time has been calculated from the satellite data transmissions. From a

‘cold’ start this process will typically take less than 10 minutes.

Ensure that the TimeLord is configured to synchronise from the GPS signal by following the procedure on page 5-3.

Once the green LED has illuminated the synchronising time signals are transmitted from the GPS system to the TimeLord.

The TimeLord Master Clock should lock in and display the correct time within 5 minutes.

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.

On 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.

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.

B w482 Code + w482 Code -

EMC grounding point

Note:

Polarity of connection is not critical.

If a screened cable is used for system interconnection, the screen should only be connected to the EMC grounding point on the TimeLord.

The w482 ® signal was developed for controlling electronic clocks, using a single cable pair data interconnection, in electrically noisy environments. A principal advantage of w482 ® is the ability to provide time information in any one of fifteen different synchronised time zones. All fifteen time zones can be individually configured from the front panel of the TimeLord, using ‘Set Once’ technology to allow automatic seasonal time change correction.

The w482 ® signal is transmitted at 4-24v amplitude and at a

50 bits per second data rate. The signal is virtually immune to electro-magnetic interference.

One TimeLord unit can control up to fifty 400A series slave displays located up to 1km from the master clock unit using a simple, non-critical cable pair.

Setup Procedure

1 Decide what time you want to display on your slave clocks. If you just want to display Local Time, as previously programmed during ‘location’ setting (section

4), proceed to stage 2.

If you have more than one time zone to display or want to display a different time zone from that set in the location setting, determine the zone location codes

(Page 4-2) and program w482 zones ‘2’ - ‘A’ accordingly.

Ensure that the TimeLord system is disconnected from the mains power supply when making connections to the w482 output.

Connect the V-400A slave clocks to the TimeLord w482 output terminals. (See above and page 6-2).

Check that the V-400A (or V-470A) slave clock is programmed for w482 time code synchronisation. If the V-400A (or

V-470A) slave clock is to be synchronised by a w482 time zone which is not zone 1, program the V-400A (or V-470A) clock accordingly.

Refer to the V-400A (or V-470A) series operating and installation manual for more details.

Apply power to the TimeLord.

Note: If you using the IRIG output (IRIG-OUT versions only) or EBU output (EBU-OUT versions only) and are using it in an application that requires the location setting to be set to a time zone other than the local time zone, w482 zone

2 should be programmed for the local time zone and the slave displays should be configured accordingly.

Additional serial outputs (.S2 & .S4 versions only)

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).

Setting the Message Format

The TimeLord has 71 different preprogrammed serial output messages. The desired message can be selected from the lists on page 7-2 and programmed into the TimeLord using the procedure on page 7-5. Please also refer to Appendix C for details of products compatible with the TimeLord.

Setting the Output Message Time Offset

The TimeLord serial output message may be referenced to the current location setting (see section 4) or UTC/GMT as detailed in the procedure on page 7-5 .

Data Formats

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.

8 - Relay Setup

TimeLord Relay Connections

10 way terminal block no nc

Note:

N.O. Contact

N.C. Contact

Common

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.

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.

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.

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.

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.

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.

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.

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.

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

Internet.

Each connected computer must have a unique address to ensure that data transmitted from one location reaches the correct destination.

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.

H o s t

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.

H o s t

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.

9-2

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

C l a s s B 1 1 1 1 1 1 1 1

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’.

Optional IRIG Interface

BNC Connector

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.

IRIG Setup

The different IRIG settings are detailed in the table below. The

IRIG setting procedure is shown graphically in the diagram to the right of this text.

Setting the IRIG Signal Time Offset

The IRIG signal is referenced to the current Location setting

(see section 4). If the output message is to be referenced to

UTC/GMT the location setting should be set to 0.

RS485 level IRIG output

The IRIG signal is available at RS485/422 levels from the S1 serial output if the ‘i485’ setting is selected. Please note that if the ‘i485’ option is set to ‘yes’, the S1 RS485 interface cannot be used for serial data output.

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.

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

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

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.

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.

Appendix A - Cable Specifications

TimeLord-> V-488B/C GPS interconnection

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

25 metres of four core 7/0.2 (0.22mm

2 ) 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 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 (0.5mm

2 ) cable should be used.

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

V-488BGPS Receiver cannot be extended.

TimeLord -> V-484 MSF and DCF radio receiver interconnection

The V-484 series radio receiver is supplied with a 5m long unscreened cable as standard.

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.

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.

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 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.

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).

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

1.5mm

2 ) 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

2 Pirelli

PSX™).

Unscreened data cables should not be run in proximity to power cables supplying fluorescent lighting or other sources of electrical noise.

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 10Base-

T 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.

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.

In the Network Setting menu, program the default

Gateway of TimeLord-Net-Client in dotted-decimal notation.
