KONGSBERG K-Sync

System description

The K-Sync is a compact synchronization system designed to support all types of echo sounders, sonars and other hydroacoustic instruments provided with an external transmission trigger option. The K-Sync can control the transmission for up to 16 hydroacoustic systems.

The K-Sync synchronization system consists of the following main components:

• Synchronization Unit

• Application software

Note

The Synchronization Unit is available in two physical versions; a cabinet version for bulkhead installation, and a 19” rack version.

The K-Sync synchronization system is controlled from a commercial computer running the K-Sync application software. This software provides the user interface, which allows you to monitor status and transmit trigger schedule, and menu for Settings and Tools for Diagnostic display .

Figure 1 19" rack version

The computer running the K-Sync application software needs to interface the Synchronization

Unit for the system to initialize. This interface is made using an Ethernet line. Once the K-Sync system is running, the application software can be closed, and the computer disconnected from the Synchronization Unit. The K-Sync

Synchronization Unit will then continue to control the transmission of the hydroacoustic systems as a stand-alone unit.

Figure 2 Cabinet version

The Synchronization Unit can receive depth data from an echo sounder or another external source.

This interface is also made using Ethernet, and an additional network switch is then required.

The depth information is used by the K-Sync to establish the trigger sequence for hydroacoustic systems that do not return any "ready to transmit" information.

B Hydrographic Work Station

C Hydroacoustic systems (sonars, echo sounders) controlled by the K-Sync

The K-Sync Synchronization Unit can control up to maximum 16 hydroacoustic systems.

Unless otherwise specified in a contract, the Hydrographic Work Station and the display are not included in the standard delivery from Kongsberg Maritime. These are commercial items that can be purchased locally. A laptop computer can be used if it meets the requirements for K-Sync operation.

342741/B

KONGSBERG K-Sync

Concept description

The K-Sync synchronization system offers a highly adjustable timing of transmissions

("pinging") when multiple echo sounders, sonars or other hydroacoustic instruments are employed on a vessel.

The K-Sync synchronization system controls and optimizes the timing for each transmission from each hydroacoustic system. This timing ensures that systems that may interfere with each other do not transmit simultaneously, as this could result in acoustic interference and degraded data.

The K-Sync provides flexible control of the transmit scheduling. The trigger schedule can be tailored to the particular type of survey you are about to perform. Any echo sounder, sonar or other hydroacoustic system that has an input for external transmit triggering can be controlled.

The K-Sync schedules the hydroacoustic systems to transmit according to trigger groups.

There is a total of 16 trigger groups. Any number of hydroacoustic systems (or none) can be assigned to a group. Each group is triggered one by one, while the systems assigned to a group are triggered simultaneously. Once it is determined (by reading feedback signals) or estimated (based on input depth and/or your parameter settings) that all the hydroacoustic systems in the current group have completed their transmission cycle, the next group is triggered. All groups are triggered in a circular order. The duration allocated to each group is not fixed and depends on the maximum active period defined for the hydroacoustic systems in that group.

Systems can be taken out of the schedule without changing the group schedule. This is done by simply disabling them. If a group does not contain any available hydroacoustic systems, that group is skipped.

If the "ready to transmit" feedback signal is available from a specific hydroacoustic system, the duration of the active period allocated to the group is set to the time it takes for the signal to become active after the hydroacoustic system has been triggered.

If the transmitting feedback signal is available, the K-Sync will automatically check that a transmit occurred after each trigger. If the hydroacoustic system fails to transmit three times in a row, it is assumed that it has been turned off. It is then taken out of the schedule.

Feedback signals are ignored when Calculated and Fixed Period are used in runtime settings.

Network security

If a K-Sync system is connected to a local area network, data security is important.

Equipment manufactured by Kongsberg Maritime is frequently connected to the vessel's local area network (LAN). When you connect a computer to a local area network you will always expose the data on that computer. All other computers connected to the same network may be able to access your data. Several threats may immediately occur:

• Remote computers can read the data.

• Remote computers can change the data.

• Remote computers can change the behavior of the computer, for example by installing unwanted software.

Usually, two parameters are used to define the threat level:

1 The likelihood that any remote computer will do any of the above.

2 The damage done if a remote computer succeeds doing this.

342741/B

KONGSBERG K-Sync

Kongsberg Maritime has no information regarding the complete system installation on any vessel. Systems provided by Kongsberg Maritime are regarded as stand-alone offline systems. They are stand-alone even though they may be connected to a network for sensor interfaces and/or data distribution.

Note

No network safety applications are installed on Kongsberg Maritime computers. The computers are therefore not protected against viruses, malware or unintentional access by external users.

Securing the K-Sync system itself has no meaning unless there is a policy in place that secures all computers in the network. This policy must include physical access by trained and trusted users. The customer/end user of the K-Sync system will always be in charge of defining and implementing a security, policy and providing the relevant network security applications.

Note

Kongsberg Maritime will not accept any responsibility for errors and/or damages caused by unauthorized use of or access to the K-Sync system.

If you wish to connect the K-Sync system to the ship's local area network, you must implement the same security mechanisms on the K-Sync computer(s) as for the rest of the network. This is a task for the network responsible person on board. Some key elements here must be:

• The same anti-virus protection on all computers, including routines for updating this protection.

• The same settings for the firewall on all computers.

• Controlled physical access to computers on the network.

• Trusted and trained operators.

• Log-in access mechanisms.

• Same policy for attaching peripheral equipment to the computers (USB devices, hard drives etc).

• Installation of programs on any computer in the network, verification that each program is authentic.

• Definition of which programs are allowed to run on each computer.

• Logging mechanism of computer activity, and inspection of these logs.

How to define and implement these rules depends on each end user's network system configuration, which again must be a result of the policies and threat levels the end user has defined for the complete installation. For some products the network consists of only processor units and/or work stations, transceivers and a few sensors. On other vessels, larger computer systems can be installed to include numerous products and data systems.

There must be one responsible person for the security of the system, large or small.

Echo Sounder Signal characteristics

Signal naming conventions

Manufacturers use several names to denote the various signals. The first column in the table below shows the signal name that has been adopted for the K-Sync application.

The second column shows the typical names used for the corresponding signal of the sonar. These are names used by the Kongsberg echo sounders

Description

Signal is active when sonar is ready to transmit; inactive while the echo sounder is transmitting, receiving or processing samples. Signal may also go inactive whenever pinging for the particular echo sounder is turned off, which will be properly interpreted by K-Sync.

To K-sync Signal is active (by default) for the duration of the transmit pulse.

From K-sync Signal causes sonar to ping.

RTT - Ready to transmit

RTS - Ready to send

CTS - Clear to send

K-Sync Signal Interface

K-Sync controls pinging and receives status from the echo sounders via the signal interface and provides one output and two inputs for each echo sounder:

• Trigger output: tells the echo sounder when to transmit/ping

• Ready to transmit (RTT) input: communicates when the echo sounder is ready for next trigger

• Transmitting input: tells the Synchronizing Unit when the echo sounder has started and is in the process of transmitting

Feedback signals from the echo sounder

Feedback signals are not required but will be used when available. If feedback signals are not available, the Synchronizing Unit can estimate the waiting period required for the echo sounder to become ready.

342741/B

KONGSBERG K-Sync Installation manual

The feedback signals communicate whether an echo sounder is ready to be triggered, and if transmit occurred.

When the Ready To Transmit signal is active, the Synchronizing Unit can trigger the echo sounder. Once the ping cycle starts, it is required that the signal go inactive. Once ping cycle is complete and echo sounder is ready again, the signal must once again become active. It also works well if echo sounders keep this signal inactive when they are not configured for external pinging as they will instantly be placed into standby mode.

The Transmitting signal goes active at the instant when the transmit pulse starts. It is not required that the pulse length of this signal is the same as the transmit pulse itself.

If the signal is available, the trigger display will show a red pulse whenever the echo sounder transmits. Even if the echo sounder is not controlled by the Synchronizing Unit, a red pulse will appear whenever the transmitting signal is set by echo sounder.

Note

The red visualization of the pulse is not identical to the actual pulse.

If an echo sounder fails to transmit three times in a row upon being triggered, the echo sounder will assume that the echo sounder is no longer available. The echo sounder is assumed to not be responding if it has not transmitted within 512 ms of trigger. In this case it will be put into standby and the system will not be triggered by the Synchronizing

Unit until the operator disables and re-enables the system in echo sounder status.

Trigger output to the echo sounder

The trigger output is a pulse generated by the Synchronizing Unit to signal the echo sounder to ping. The pulse width can be specified in 1 ms increments.

Note

There are wide differences among echo sounders in their implementation of the signal interface. Consult the product manual for the individual systems for specific information on timing and signal specification.

Logic states and their corresponding voltage levels

Note

In this manual Signal active refers to a particular voltage level which is present for a specific state, but does not imply whether this voltage is negative, 0 or positive. Using this generic terminology avoids confusion. For example, RS-232 signals that are between

-12 and -3 V is considered a logic "high" and +3 to +12 V is considered a logic "low."

342741/B

Echo Sounder Signal characteristics

To configure K-Sync you must specify whether the input/output is active high or active low. See table below for the actual voltage levels associated with this setting. The level also depends on whether the input has been configured for TTL or RS-232 from the factory.

Table 2 Logic states, voltage levels

Active high

>+3V (+12V)

<-3V (-12V)

* For trigger outputs the RS232 levels are either +12V or -12V.

To illustrate, if the manufacturer specifies that the ready to transmit signal is TTL and active when voltage is +5V, then from the table above, the signal active should be configured as active high. Likewise, an RS-232 signal that is specified to be active when voltage is > + 3V should be configured as active low (as RS-232 signals are inverted internally).

RS-232 and TTL signal active

• Ready to transmit:

– RS-232; if negative voltage (-12V to -3V) denotes active, then the signal is active high.

– TTL; if +5V denotes active, then the signal is active high.

• Transmitting:

– RS-232; if negative voltage (-12V to -3V) denotes active, then the signal is active high.

– TTL; if +5V denotes active, then the signal is active high.

• Trigger:

– RS-232; if positive voltage (+3V to +12V) to negative voltage (-12V to -3V) causes transmit, then the trigger active level is high (trigger on rising edge).

– TTL; if 0 to +5V causes transmit, then the active level is high.

KONGSBERG K-Sync Installation manual

I/O module configuration

The echo sounders can be connected to the I/O modules in any order. The modules configure how the voltage levels are to be interpreted; while the K-Sync Application handles the remaining signal properties and assignments.

Tip

The terminal ID (module and pin number) can be assigned to one or more echo sounders in the software (thus it is possible to use one feedback signal for several systems in special applications).

Tip

It is important to be methodical during installation as there are several steps that needs to be performed and each step needs to be done right for the system to function as a whole. The approach that should be followed is to configure one system at a time then move on to the next. Check your assumptions along the way!

Ready to transmit timeout

The timeout is set in seconds and determines how long the system should wait for a

“Ready to transmit” signal before timing out and disabling the sonar in question. The value entered here would therefor need to be different depending on the operational depth and the swath width of the system in question.

For example, an EM 124 system operating at 4000m depth is expected to have a swath width of 144 degrees, and so it has a total slant range of approximately 12.900m.

342741/B

KONGSBERG K-Sync Installation manual

Assuming an average sound velocity of about 1450 m/s through the water column, the total return trip travel time of a single ping is about 18 seconds. So after about 18 seconds,

“Ready to transmit” signal would normally become available again. Entering an exact return trip value is not recommended. For any one sonar and system there may be other factors like system latency that will effect the ping cycle of the systems. Make sure to test the calculations with the sonar in question to confirm that the system has the expected ping rate vs depth. Then enter a value that reflects the maximum slant range expected for the survey and then add some seconds to allow for delays and changes in topography.

Why does the system disable the sonar?

Disabling the sonar removes it from the trigger schedule and thus stops it from hindering the triggering of the groups after it in the trigger group schedule.

Determine which signals need to be interfaced and their characteristics

Context

Note

The echo sounders must be powerless during cable connection.

Multiple hydroacoustic systems operating simultaneously on the same vessel may cause interference. In order to minimize this interference, the K-Sync Unit system can be used.

All echo sounders that will be synchronized are required to have at least a trigger input signals in order to be controlled by K-Sync.

TTL and RS-232 level signals are supported. Other signal levels are not yet supported.

7 Change Pulse length and Is available settings back to original value in the dialog.

If there is no response to trigger:

• Is the echo sounder set up correctly, e.g. is the external trigger configured on the echo sounder workstation, and is all equipment powered up?

• Is pull-up or pull-down set correctly (if the signal is TTL)?

• Is the pulse length setting within the spec for the echo sounder?

• Is the signal either RS-232 or TTL compatible? Verify voltage for both voltage states using an oscilloscope or a digital volt meter.

Determining signal properties of Ready to transmit

1 Verify that the echo sounder is powered on and that the echo sounder software is set up and is ready for external trigger.

2 Disable the echo sounder in the K-Sync application by unchecking the Enabled checkbox so that the system goes into Standby .

The echo sounder should now continuously be ready and waiting for a trigger pulse from synchronizing module.

3 Observe the top-left of the four LEDs, the Ready to transmit (in) .

Is the LED on or off? If "on" the echo sounder should be configured as Active high , otherwise Active low .

4 Confirm by setting the system up for transmitting once every second (set the echo sounder up for Fixed period trigger every 1000 ms in Runtime Settings ). Does the

LED change state at time of trigger? If so then the signal is behaving as expected.

Determining signal properties of Transmitting

1 Verify that the echo sounder is powered on and that the echo sounder software is set up and is ready for external trigger.

2 Make sure the echo sounder is enabled in the K-Sync Application window found in the Echo Sounder Status area.

3 Configure Runtime settings to use Trigger mode : Fixed period and set the Fixed period to 1000 ms.

4 Observe the bottom-right of the four LEDs, the Transmitting (in) .

Observe that the Transmitting LED blinks each time the echo sounder is being triggered by the Synchronizing Unit. The pulse length might be too short to notice, especially if pulse width is less than 10 ms or if the LED is normally on and instead turns off during transmit. If so, connect an oscilloscope to observe the signal. If

342741/B

Cable layout and interconnections

the LED is normally off and turns on during transmit, then the signal is Active high . If always off, then it is Active low .

Cable layout and interconnections

A standard commercial AC mains cable is used. The power cable is normally terminated with an female IEC C13 inline socket. The AC mains end is terminated in an AC connector suitable for the local standard and/or the output sockets on an uninterruptible power supply (UPS). If this is not the case, you must replace the AC connector.

The typical cable length is between 1,5 and 2 meters. If this is too short you must use an extension cable (not recommended), mount a new power outlet within range, or make your own power cable with sufficient length. If you use an uninterruptible power supply

(UPS), you can also move the UPS to a different location within range.

Note

There are substantial differences between countries nomenclature related to power plugs and sockets. Observe local standards and regulations.

RJ45 High speed Ethernet cable (1000Base-t)

Most high speed data connections between the K-Sync system units are made using

Ethernet cables. These cables may also be used between the K-Sync and peripheral equipment.

A Local Ethernet connection

B Connection on external network device

Ethernet cables are available commercially in different lengths, colours and categories. Normally,

CAT-5E and CAT-6 cables are used in local area networks with bandwidths exceeding 100 Mbit.

Minimum cable requirements

It is very important that high-quality Ethernet cables are used. You must use CAT-5E quality or better. If you use cables with lower bandwidth capacity you will reduce the performance of the K-Sync system.

It is important that the cable has shielded twisted pair.

K-Sync interface to generic RS-232 synchronization input

For transmission synchronization purposes, the K-Sync will interface a generic RS-232 serial line communication port using the CTS (Clear To Send) and RTS (Request To

Send) signals.

The synchronized product is connected to the IO Module inside the K-Sync

Synchronizing Unit. Each IO Module in the K-Sync Synchronizing Unit provides six connectors and a configuration board for physical adjustments of the communication parameters.

Signal description

This signal is transmitted to the system that needs to be synchronized. Trigger Out allows the system to transmit

("ping").

Mandatory! This ground is connected to pin 5 inside the IO

Module.

Ready to Transmit: Ready to Transmit (RTT) is a return signal from the hydroacoustic system that is synchronized.

The Ready to Transmit (RTT) signal means that the hydroacoustic system is ready for the next trigger.

This signal is received from the system that needs to be synchronized. Trigger In is "active" while the system is transmitting.

Mandatory! This ground is connected to pin 2 inside the IO

Module.

Cable gland procedure

Cable glands are used whenever a cable passes through a water-tight bulkhead or into a cabinet, to seal the opening through which the cable passes and to protect the cable from abrasion on the edges of the hole. Follow the guidelines detailed here when installing cables through cable glands.

Prerequisites

Ensure that all the cables to be connected are completely isolated from any power sources.

Verify that no safety interlocks have been bypassed. A minimum of 5 to 10 cm of slack cable must be allowed (depending on the cable diameter and arrangement), both inside and outside the cabinet, when installing cables.This is to allow for vibration damping, maintenance and measurement errors. Always double-check your measurements before taking any irreversible actions.

With a steel conduit the installation will satisfy the European Union regulations for electromagnetic compatibility (EMC) interference. Without a steel conduit, there is a risk of reduced performance.

Context

Note

The screen in cables must never be connected to ship’s ground in the cable glands!

Tag out the system properly.

Procedure

1 Select the cable to be connected, and select the cable gland to use. Make sure you use the correct size cable gland according to the cable size. The cable glands are included in the delivery.

2 Slacken and remove the compression nut from the cable gland, and extract the compression seal and the screen collar from the body of the gland.

3 Depending on whether the cable has already been installed in conduits, either:

• (Installed) measure the maximum length of cable required to reach from the final cable clip outside the cabinet to the terminal blocks inside the cabinet, add 20 cm, then remove the excess cable,

• (Loose cable) measure the maximum length of wire required to reach from the cable gland to the terminal blocks inside the cabinet, add 20 cm. and mark the cable

4 Pull the cable through the steel conduit.

5 Carefully remove the outer insulation from the required cable length.

Do not damage the screening.

Leave 12 mm of the screen exposed from the insulation, cut off the remainder.

6 Make sure that an ample length of the cable is available for maintenance and replacement.

7 Cut the cable.

8 Remove the insulattion on the shield in the cable.

9 Cut the shield, to just cover the seal.

10 Remove the insulation on the wires in the cable.

11 Add an end sleeve to the wires.

12 Fit the cable gland into the unit cabinet.

13 Connect the cable cores to the appropriate terminals within the cabinet.
