The NMEA 0183 (National Marine Electronics Association) interface allows the EQ 55 to communicate certain data with other devices that may be on your vessel.

The EQ 55 sends out signals on the NMEA 0183 interface giving the water depth it is measuring.

Also, the EQ 55 will receive latitude and longitude information from a Loran, Transit Sat-Nav or GPS

receiver. If this the vessel's position to the EQ 55, turning the NMEA 0183 interface will allow the EQ 55 to display the latitude and longitude

The Time Varying Gain (TVG) is a control that allows the EQ 55 to make corrections for most of the losses and absorption that occurs as sound energy passes through sea water.

Each channel has its own TVG adjustment. Generally speaking, if you are searching for small targ ets or a re looking for the best picture of the bottom at great depths, use "FISH" (40logR).

If you are observing large schools of fish or have excessive noise on the display screen, try the "BOTTOM" (20logR) setting.

The Depth Adjustment function acts as a draft offset, allowing the digital depth indicator in the lower left corner of the display screen to indicate the depth from the surface, rather than depth from the transducer.

The value shown above "Status" in the Status window, when making the depth adjustmen t, is th e depth, in meters, which is added to the depth from the transducer to give the digital displayed depth.

Note: The target data and the scales shown alongside

the target data do not change.

3. PRINCIPLES OF OPERATION OF AN ECHO

SOUNDER

3.1 PARTS OF AN ECHO SOUNDER

An echo sounder is composed of the display screen, processor, and receiver/transmitter unit which in case of the EQ 55, are housed in one unit which should be installed in an easily accessible location aboard ship. Connected to this unit by shielded cables are the transducer(s) which are mounted horizontally on the bottom of the hull.

3.1.1 Display Screen

The display screen presents in graphic and numerical form the information the processor is receiving and accumulating from the transducer(s).

3.1.2 Processor

The processor is the "brains" of the echo sounder. It is sealed inside the unit which protects it from harm. The processor is composed of highly sophisticated microprocessor, memory and logic circuitry.

3.1.3 Receiver/Transmitter

The receiver/transmitter (often called the "transceiver") section of your echo sounder takes it's commands from the processor. The processor tells the transceiver to activate the transmitter. The transmitter sends a high voltage transmit "ping" to the transducer mounted on the hull. At that point the transmitter's job is done and the receiver takes over. See Figure 3.1

The receiver is also connected to the transducer and amplifies the very small signals received as echoes from fish and the sea floor which arrive at the transducer (see Figure 3.2). The receiver is designed to reject other signals as much as possible and to provide enough amplification to see even relatively small targets at long ranges. The amplified receiver signals are then sent to the processor to be shown on the display screen.

3.1.4 Transducer(s)

A transducer is composed of a number of elements embedded in a housing which has been reinforced with polyester or fiberglass. The transducer is attached horizontally to the bottom of the hull. It is essential that the transducer be mounted properly as echo transmissions are radiated at right angles from the transducer face. Shielded cables connect the transducer with the echo sounder.

3.2 HOW THE EQ-55 WORKS

When the EQ-55 is turned on the processor begins to send an electrical voltage to the transducer. The cylindrical resonators in the transducer have a special property which enables them to change dimensions slightly when a varying voltage is applied. The voltage is thus converted to mechanical vibrations (sound waves) which are then transmitted down through the water. See figure 3.1

Figure 3.1 Transmitted “ping” from the receiver/transmitter

EQ-55 Operators Manual 950-70017001/Iss 1.

Principles of Operation of an Echo Sounder Page 3.5

The sound waves move through the water until they encounter a change in density, such as a fish or the bottom. This causes the sound waves to " echo " back up through the water. When the reflected sound waves (echoes) hit the transducer the ceramic disks vibrate at the same frequency. This voltage goes back up through the cables to the receiver. The EQ-55 processes the signals and presents them on the display screen. See Figure 3.2

Figure 3.2 Echoes returning to the receiver

3.3 TRANSDUCER BEAMWIDTH

The transducer mounted to the hull of your vessel serves as both a "speaker" when transmitting, and as a "microphone" when the echo sounder is receiving. Similar to the way a flashlight focuses light, most of the sound from your transducer is focused downwards with a smaller amount going out to the sides. The amount of focusing of the sound beam is expressed as a "beamwidth".

Page 3.6 Principles of Operation of an Echo Sounde

Figure 3.3 A representation of a transducer beamwidth

The center of the sound beam is the most intense, then as you move out towards the sides of the sound beam there is a point where the intensity of the sound is 1/2 what it was in the center. The distance moved is the "beamwidth". It is nothing more than a number telling you if your transducer is functioning more as a spotlight (a narrow beamwidth) or as a floodlight (a wide beamwidth) See figure 3.3

A narrow beamwidth transducer will do a better job of showing two separate fish schools that are close to each other (see figure 3.4), whereas a wider beamwidth will tend to show them as one large school (see figure 3.5). Since a narrow beamwidth transducer focuses the sound better, it is usually capable of seeing deeper targets than the wider beamwidth transducer.

Figure 3.5 A wide beam transducer

However, narrow beamwidth transducers have drawbacks too. As a ves s el rolls , the sound beam swings back and forth, and can occasionally be pointing too far to port or starboard to see a small target clearly. The choice of transducer beamwidth is always a compromise. See 3.6

3.4 CHOICE OF FREQUENCY

Your EQ-55 has two built-in frequencies. The lower frequency is mos t us ef ul f or work in deep water. The high frequency will not usually be able to see as deep as the lower frequency, but the higher frequency is best for seeing small targets and greater detail. For example, looking for small bait fish is best done with the high frequency. The operations section of this manual will show how to choose the frequency displays you need. See Figure 3.7

Figure 3.7 - A representation of low frequency versus high frequency.

3.5 EFFECTS OF THE VESS EL'S SPEED

The display of fish on the EQ-55 depends directly on the vessel's speed, as well as on the depth of the fish. When the vessel is at rest, the echo traces will appear stretched out and flattened. As the vessel's speed becomes greater, the echo traces will become shorter and more arched. The reason for this change in

appearance is that the vessel's speed increases, fewer number of sound "pings " strike each fish A low vessel speed will provide the most accurate information of where fish are located. See figure 3.8

EQ 55.

4.1 BASIC INFORMATION

4.1.1 Power Supply Requirements for Installation

The system will operate at either 115 or 230 VAC, at a frequency of 50 or 60 Hz. The power input connector contains two fuses each rated at 2 amperes. To remove or replace the fuses, pry the cover off the connector using a small screwdriver. The AC voltage selection is done manually. To change this voltage, the selector card inside the line filter has to be placed in the correct position. See figure

4.1.2 Cable and Transducer Information

The installation should be carefully planned in advance, keeping in mind the standard cable length of 32 feet (10 meters) which will be connected to each transducer. In the event where the standard cable is not long enough, up to an additional 32 feet (10 meters) may be connected without affecting the performance of the transducer. The cable must be of the same type as the standard two core shielded cable. Coaxial cable must not be used.

The use of longer cable runs, while possible, always increases the likelihood of increased interference and decreased performance. Care must be taken when increasing the cable lengths to ensure that proper, adequate and consistent shielding is maintained, that cable of adequate cross section is used, and that all connections are properly made and protected from the effects of the marine environment.

If possible, running the transducer cable through a grounded conduit will greatly decrease the likelihood of interference. Likewise, the EQ 55 transducer cable should be run as far as possible from other electrical cabling. If it is absolutely necessary to pass close to other cabling, it is best to keep as much distance as possible, and to make all crossings as close to a right angle as possible.

The EQ 55's transmitter is designed to match the following transducers: (see Section 4.1.3 on the next page).

4.3 DETERMINING THE POSITION FOR THE TRANSDUCER

4.3.1 General

A single answer to the question where to locate the transducer cannot be given. It depends very much on the vessel’s construction. However, there are some important guide lines.

4.3.2 Go Deep

The upper water layers of the sea contain myriads of small air bubbles created by the breaking waves. In heavy seas the uppermost 5-10 metres may be airfilled, with the highest concentrations near the surface. Air bubbles absorb and reflect the sound energy, and may in the worst cases block the sound transmission totally. Therefore, mount the transducer at a deep position on the hull.

Consider the situation when the vessel is unloaded, and when it is pitching in heavy seas. The transducer must never be lifted free of the water surface. Not only will the sound transmission be blocked, but the transducer may be damaged by slamming against the sea surface.

Another reason to go deep is cavitation in front of high power transducers. Cavitation is the formation of small bubbles in the water due to the resulting local pressure becoming negative during parts of the acoustic pressure cycles. The cavitation threshold increases with the hydrostatic pressure.

4.3.3 The Boundary Water Layer

When the vessel forces its way through the sea, the friction between the hull and the water creates a boundary layer. The thickness of the boundary layer depends upon vessel speed and the roughness of the hull. Objects protruding from the hull, and dents in the hull, disturb the flow and increase the thickness of the boundary layer. The flow in this boundary layer m ay be lami nar or turbulent. A laminar flow is a nicely ordered, parallel movement of the water. A turbulent flow has a disorderly pattern, full of eddies. The boundary layer increases in thickness when the flow goes from laminar to turbulent. Figure 4.1 sketches the boundary layer of a vessel moving through the water.

Furthermore, air bubbles in the sea water are pressed down below the hull and

Kongsberg Simrad Mesotech Ltd.

Port Coquitlam, BC - Canada

950-70017001/Iss 1.2 EQ-55 Operators Manua

Page 4.12 Installation Instructions for the EQ-55

mixed into the boundary layer. The Boundary layer is thin underneath the forward part of the vessel, and increases in thickness as it moves af tw ards . If the sides of the hull are steep, some of the air bubbles in the boundary layer may escape to the sea surface along the vessel sides. It is our experience that a wide and flat bottom, with a rising angle less than around 13 degrees, is prone to giving air problems for the transducer. In any case a transducer location in the forward part of the hull is preferred in order to minimize the influence of the boundary layer.

Figure 4.1 Sketch of the boundary layer underneath the vessel.

4.3.4 Propeller Noise

The propulsion propeller is the dominant noise source on most fishing vessels, research vessels, merchant vessels and pleasure crafts. The noise is transmitted through the sea water. Therefore, the transducer should be placed far away from the propeller, which means on the fore part of the hull. Positions outside the direct line of sight from the propeller are favourable. On small vessels with short distances it is advised to mount the transducer on that side of the keel where the propeller blades move upwards, because the propeller cavitation is strongest on the other side. The cavitation starts most easily when the water flows in the same direction as the propeller blade, and that is to some degree the case at that side of the keel where the propeller blades move downwards.

Kongsberg Simrad Mesotech Ltd.

Port Coquitlam, BC - Canada

EQ-55 Operators Manual 950-70017001/Iss 1.

Installation Instructions for the EQ-55 Page 4.1

Bow thrusters are awful machines. When they are in operation, the noise and cavitation bubbles make the echo sounder useless, almost no matter where the transducer is installed. And when not in operation, the tunnel creates turbulence, and if the vessel is pitching, the tunnel may be filled with air or aerated water in the upper position and release this in the lower position. Therefore, an echo sounder transducer should be placed well away from the bow thruster.

4.3.5 Vessel Heave

Heave is the up and down movement of the vessel. It disturbs the echo traces in the echogram, so that a flat bottom is displayed as a wave. A transducer location in the middle of the vessel minimizes the influence of vessel roll and pitch.

4.3.6 Noise From Protruding Objects on the Hull

Objects protruding from the hull, such as zinc anodes, sonar transducers or even the vessel’s keel, generate turbulence and flow noise. Also holes and pipe outlets are noise sources. They may act as resonant cavities amplifying the flow noise at certain frequencies. Do not place an echo sounder transducer in the vicinity of such objects, and especially not close behind them.

4.3.7 Summing up on Transducer Location

Some of the above guide lines are conflicting, and each case has to be treated individually in order to find the best compromise. Generally the propeller noise is the dominant factor, and a recommended transducer location is in the fore part of the hull, with maximum distance from the bow equal to one third of the total length of the hull at the water line, see Figure 4.2. If the vessel hull has a bulbous bow, this may well be a good transducer location, but also here must be taken into consideration the flow pattern of the aerated water. Often the foremost part of the bulb is preferable as shown in Figure 4.3.

4.3.8 Thru-hull Installation

Typical thru-hull installations are illustrated for transducers on the following pages. The leveling blocks shown are to be supplied by the installer. Any gaps between the block and the transducer should be filled up with mastic and the entire surface should be made as smooth as possible to provide an undisturbed flow of water over the transducer face.

To ensure a watertight installation, apply a liberal amount of high quality sealing compound inside the mounting holes and around any hardware that penetrates the hull.

The stuffing tube and the transducer housings may be painted with anti-fouling paint.

CAUTION: The face of the transducer should be left unpainted or decreased performance will result Do not allow solvents to come into contact with the transducer face.

Steel stuffing tubes are available for use on steel vessels. Note that bronze stuffing tubes should not be used on aluminum hulls.

4.4 DISPLAY UNIT INSTALLATION

The display unit is designed to function normally on a continuous basis in the high humidity of a marine environment. However, to ensure the long term performance and reliability of the display unit, it should be installed in a dry, well ventilated location. Avoid installation in areas where heavy shocks or vibrations are expected or where the unit will be exposed to high temperatures.

Using the mounting bracket the EQ 55 Display Unit may be "table top" mounted (see Figure 4.14) or the EQ 55 may be mounted to the ceiling

The EQ 55 may also be recess mounted into a control console and rack mounted. Be sure that there is no tension applied to the cabling when the installation is

complete. Choose a mounting surface that is strong enough to support the cabinet weight (60

pounds/27 kg) under extreme operating conditions. Reinforce the mounting surface if necessary.

Provide sufficient clearance around the cabinet to allow free circulation of air and to gain access to the connectors and fuse. Do not block the sides, bottom or rear panel of the cabinet or overheating will occur.

The display unit can be mounted on a table top, bulkhead or over head by using the supplied mounting bracket. See mounting hole pattern drawing, Figure 4.15.
