System Description The Kongsberg EM 2040 is an advanced multibeam echo sounder.

Key features include:

• Frequency range from 200 to 400 kHz

• FM chirp allowing much longer range capability (depth and coverage) compared to CW pulses

• Complete roll, pitch and yaw stabilization

• Nearfield focusing on both transmit and receive

• Operates with very short pulse lengths – shortest pulse is 25 microseconds

• The depth rating of the subsea parts is 6000 metres

• IHO-S44 special order compliant

• The EM 2040 has two TX array sizes:

– EM 2040-04 (0.4 degrees at 400 kHz)

– EM 2040-07 (0.7 degrees at 400 kHz)

The EM 2040 multibeam echo sounder is the first system to bring all the advanced features of deep water multibeams to the near bottom sounding environment.

The EM 2040 operating bandwidth is from 200 to 400 kHz, which is a full octave, and this is achieved using the standard transducers. Three standard modes are available. 300 kHz is used for normal operation, giving an optimum balance between high resolution, 8 391932/C depth capability and tolerance of performance deteriorating factors such as water column sediments. 200 kHz is available for meeting requirements to operate at the standard hydrographic single beam frequency, but also to achieve the best depth capability. 400 kHz is provided for inspection work with the utmost resolution.

EM 2040 has the functionality of the lower frequency EM systems, and the small size and weight advantage of the high frequency systems, as well as beamwidth of 0.4 degrees.

FM pulses are used to increase the maximum range capability without sacrificing resolution. Example: 12 ms FM with 1.7 kHz sweep bandwidth compared to 600 us CW pulse (1.7 kHz bandwidth): The resolution is the same since the bandwidth is the same.

The signal to noise ratio in FM mode is increased by 13 dB. This has the same effect as increasing the transmit power level by 13 dB. The range resolution (defined as cT/2) for 600 us CW pulse is 45 cm. A 4.5 ms CW pulse would give the same coverage as 12 ms FM. But this CW pulse would give a range resolution of 200 cm (= 4.5 * 45 cm).

The normally recommended survey frequency is 300 kHz. At this frequency the bandwidth used is more than 75 kHz with three angular sectors running at separate frequencies. With dual swath six frequencies are used (with shortest pulse the total bandwidt used is more than 100 kHz). The minimum pulse length is 70 microseconds in three sectors, and reduced to 35 microseconds using one sector. With 35 μs pulse the range resolution (defined as cτ/2) is 26 mm. For deep waters FM chirp is employed with a bandwidth of 1.7 kHz. This allows a swath width in the order of 600 m and a depth capability of about 400 m in cold ocean waters.

The 200 kHz frequency mode is similar to the 300 kHz mode. It uses the same CW pulse lengths, while the FM chirp pulse length is increased. The range and depth resolution is the same. Normally two sectors are used per swath, but single sector can also be used. At this frequency the absorption in the water is lower than at 300 kHz, resulting in increased swath width and depth capability. In cold ocean waters with FM chirp a swath width of 700 m can be expected and approximately 500 m depth capability.

The 400 kHz frequency mode is intended for high resolution inspection work. Very short transmit pulses and wide receiver bandwidth is used. The operator may select between one and three transmit sectors. With a single RX transducer the coverage limit is 120 degrees (±60 degrees), and with dual RX the coverage is 180 degrees (±90 degrees). The shortest pulse used is 25 μs giving a range resolution less than 20 mm (cτ/2). It is also possible to run dual swath, but not using the shortest pulse length.

The EM 2040 is modular, allowing the user to tailor the beamwidths to the operational requirements, 0.4 by 0.7 degrees or 0.7 by 0.7degrees. The transmit fan is divided into three sectors pinging simultaneously at separate frequencies. This ensures a very strong and beneficial dampening of multibounce interference which on simpler systems often is seen at beam angles from 60 degrees and outwards. The EM 2040 has dual swath capability, allowing a sufficient sounding density alongtrack at a reasonable vessel speed.

EM 2040 also has a scanning mode, i.e. one sector is transmitted at a time, giving the possibility to use the shortest pulse length while still keeping the full swath coverage.

The standard depth rating of the EM 2040 subsea parts is 6000 m. The system is ideal for use on subsea vehicles such as AUVs or ROVs. All analog electronics are contained

391932/C 9 in the transducers, and communication to the topside processing unit is on standard Ethernet. For subsea vehicle use the processing unit may be installed in a pressure rated tank with an inner diameter as small as 230 mm.

Transducer description The transducers are the devices that transmit sound into the water and receive the echo. They are fully water tight units intended for many years of trouble-free operation in rough seas.

The EM 2040 consists of separate transducers for transmit and receive.

The system may be delivered in different versions with different transmission beam width. The standard types are:

• EM 2040-04 (0.4 degrees at 400 kHz)

• EM 2040-07 (0.7 degrees at 400 kHz) Note

The red protective coating is an vital part of the transducer. It is very important that neither this coating nor the internal parts of the transducer are damaged during the handling, installation or cleaning. Any holes and/or scratches in the transducer surface will allow water to penetrate the transducer. If a leak occurs, the transducer must be replaced.

A transducer must always be handled as a delicate item. Any wrongful handling may damage the transducer beyond repair.

Observe these rules:

1 Do not activate the transducer when it is out of the water.

2 Do not lift the transducer by the cable.

3 Do not step on the transducer cable.

4 Do not handle the transducer roughly, avoid impacts.

391932/C 13

5 Do not expose the transducer to direct sunlight or excessive heat.

6 Do not use high pressure water, sand blasting or metal tools to clean the transducer face.

7 Do not use strong solvents to clean the transducer face.

8 Do not damage the outer protective skin on the transducer.

EM 2040 Processing Unit description The EM 2040 Processing Unit is provided to process the signals to and from the transducer(s) .

The EM 2040 Processing Unit is an industrial computer using both COTS (commercial off-the-shelf) components and custom made components. The unit is designed and tested for rugged use. The Processing Unit is the central controlling device in the EM multibeam system. It administers the transmittal of pings via the TX unit(s) and reception of data from the RX unit(s).

The processing unit also supplies 48 Vdc power to the transducer(s).

Hydrographic Work Station description The Hydrographic Work Station is a maritime computer. It contains the operational software, and offers the user interface that allows you to control the EM 2040 system.

A dedicated maritime computer is provided with the Kongsberg EM 2040 system. It is set up with all necessary software.

The computer is based on the Microsoft® Windows® 7 operating system.

The computer is normally mounted on the bridge or in a scientific laboratory.

In this publication, the computer is referred to as the Hydrographic Work Station.

Ethernet switch A high capacity Ethernet switch is sometimes required.

If you use more than one Processing Unit in your EM 2040 system, you must use an Ethernet switch to connect each Processing Unit to the Hydrographic Work Station.

A high capacity Ethernet switch (1000BASE-T) is included in the EM 2040 delivery.

14 391932/C

Note

It is very important that high quality Ethernet cables are used everywhere. You must use CAT-5E cables or better. Cables with lower bandwidth capacity will reduce the EM 2040 performance.

1000BASE-T (also known as IEEE 802.3ab) is a standard for gigabit Ethernet over copper wiring. Each 1000BASE-T network segment can be a maximum length of 100 meters (330 feet), and must use Category 5 cable or better (including Cat 5e and Cat 6).

Wikipedia, April 2014

Remote Control Unit (K-Rem) description A dedicated junction box has been designed to provide remote on/off switches with light indication and interface to a remote synchronizing system. The junction box contains a terminal block and four switches with lamps mounted in the front.

Note

The Remote Control Unit is not a standard part of the EM 2040 delivery.

The Remote Control Unit is called K-Rem. It is prepared for remote control and interface to an external synchronization system for the following Kongsberg echo sounders:

• One Sub-bottom profiler (SBP 120 or SBP 300)

Note that this cable does not support all the signals in the standard RS-232 specification.

Unless otherwise specified, the serial line cable must be provided by the installation shipyard.

Important

When you are using RS-232 serial communication, observe that long runs of unshielded cable will pick up noise easily. This is because the RS-232 signals are not balanced.

Maximum length is typically 60 meters with 2400 bps data rate, but this depends on the cable quality. Always check the cable manufacturers specifications for the actual "shunt capacitance". A common figure is 47.5 pF/m, which gives a maximum cable length of about 50 meters.

Note

Even though a standard exist for RS-232 pin configuration, certain manufacturer may still choose their own connector pins for the various signals used. In order to make the RS-232 connection to your peripheral device work properly, you must always consult the relevant instructions provided by the device manufacturer.

391932/C 29

RS-422 serial line using five wires and RJ45 connector An RS-422 serial line connection can transmit data at rates as high as 10 million bits per second, and may be sent on cables as long as 1500 meters.

While RS-232 is the most common serial interface for communicating with external devices using the NMEA standard, it only allows for one transmitter and one receiver on each line.

RS-422 provides a mechanism for transmitting data up to 10 Mbits/s. This interface format uses a balanced signal on two wires. This increases both the maximum baud rate and the physical length of the cable, and it reduces the noise. With a high quality cable, you can use RS-422 on distances up to 1500 meters even in noisy environments.

RS-422 is also specified for multi-drop applications. This means that one transmitter can send data to up to 10 receivers.

Note

There are no common standard for RS-422 pin configuration. Any manufacturer may choose their own connector pins for the various signals used. In order to make the RS-422 connection to your peripheral device work properly, you must always consult the relevant instructions provided by the device manufacturer.

1PPS (One pulse per second) using a coax cable The Processing Unit is equipped with a 1PPS signal input for clock synchronization.

This cable must be provided by the installation shipyard.

1PPS cable A Male BNC connector B Ground C 1PPS signal

1PPS input The 1PPS signal is normally provided by a positioning system.

This is an optically isolated connection that requires approximately 10 mA current. The input power and the resistor value must be adjusted accordingly.

The 1PPS (one pulse per second) signal is connected to the coax connector on the CBMF board. The CBMF board is equipped with an optocoupler at this input. The input series resistor is tuned for a TTL signal (Low level<0.6 V, High level>3.2 V). It can be selected in SIS wether the falling edge or the rising edge of the signal is used by the Processing Unit to synchronize the internal clock.

The 1PPS signal must be minimum 1 microsecond long.

External Synchronization The Processing Unit (PU) is equipped with a connection for interface to an external synchronization system.

External synchronization input/output

When multiple echo sounders are employed on a vessel it is essential to optimize the timing of the transmitting of each system. The Kongsberg Maritime K-Sync Synchronizing Unit provides highly configurable timing.

The EM 2040 provides the following synchronization signals:

EM 2040 external synchronization signal characteristics

Signal Type Active

Ready To Transmit (output) Open collector output from isolation unit

High

Trig out (output) Open collector output from isolation unit

Low

Trig in (input) Optical isolated input High

• Ready To Transmit: This is an output signal from the EM 2040 to the synchronization system that goes active when the EM is ready to transmit. The signal is inactive when the echo sounder is transmitting, receiving or processing samples.

• Trig out: The EM 2040 issues a trig out signal. The trig out signal starts before the first transmit pulse and is terminated after the end of the last transmit pulse. For EM 2040 all pulses in one swath are transmitted simultaneously. With dual swath, two pulses are transmitted in sequence. The length of this trig signal is 0.7 ms plus the total TX signal length. For CW pulses the actual TX pulse is 1.5 times the nominal pulse length (because of amplitude tapering).

Reference to the Raw range and angle 78 datagram:

The transmit time for the TX pulse is referred to the centre of the pulse.

The total length of the TX pulse is given in the datagram (Signal length).

The time delay from the leading edge of the trig out pulse to the centre of the first TX pulse is:

– 506 us + 0.5 * signal length.

Example of signal length (200 kHz, Normal sector):

– Short CW: 101 µs

– Medium CW: 288 µs

– Long CW: 865 µs

– Short FM: 3 ms

– Long FM: 12 ms

36 391932/C

• Trig in: The EM 2040 can be triggered by an external signal that will cause the echo sounder to ping. The CBMF board is equipped with an optocoupler at this input. The input series resistor is tuned for a TTL signal (Low level<0.6 V, High level>3.2 V).

There is a delay from the external trig signal is received to the start of the transmit pulse (Trig out). This is caused by signal processing in the TX transducer (pitch stabilization, focus range etc).

The delay is minimum 1.5 ms and depends on the number of transmit pulses per ping (to optimize pitch stabilization). This means that the delay depends on ping mode (frequency), sector mode and swath mode (single/dual).

External Synchronization cable

This connection is used for interface to an external synchronization system (for example K-Sync) used when multiple echo sounders are employed on the same vessel. The external synchronization connector is located on the CBMF board of the processing unit.

This is an optically isolated connection that requires ~10mA current. Input power and resistor value must be adjusted accordingly.

The connector is RJ45 type.

This cable must be provided by the installation shipyard.
