Hardware installation 2 HARDWARE INSTALLATION General Before installation of the EK60, various technical aspects must be surveyed and documented. The following information describes the areas which must to be addressed. Topics → Basic procedures, page 10. → Parts and configuration, page 12. → General Purpose Transceiver (GPT), page 14. → GPT Cabinet, page 15. → Processing Unit (Computer), page 16. → Display, page 17. → Printer, page 18 → Data network, page 19 Related topics None.
Simrad EK60 2.1 Basic procedure The basic installation procedure is presented here. Detailed technical information can be found in the next chapters. The applicable page references are made in the procedure. 1) Parts configuration Check that you have received all the parts required for the installation; cables, connectors, brackets etc. 2) Transducer(s) Install the transducer(s) and the transducer cables according to the guidelines in this manual and the drawings provided with the transducer.
Hardware installation Using two or more GPTs: An Ethernet switch is required if your system includes more than one General Purpose Transceiver. in this case, use “straight” ethernet cables between the computer and the switch, and between the switch and each transceiver. Ethernet connection to sensors and other peripheral devices must be made with a second network adapter in the computer.
Simrad EK60 2.2 Parts and configurations Overview The Simrad EK60 echo sounders is designed as a modular system. It supports a variety of configurations and frequency options. While the software, the General Purpose Transceiver (GPT) and the transducer(s) must be supplied by Simrad, the computer, display, network components and peripherals may be commercial items from other manufacturers. Transducer One or more transducers are included. A large number of transducers are available from Simrad.
Hardware installation Printer A printer can be supplied. Most standard off-the-shelf colour printers can be used. A standard Windows drivers is required.
Simrad EK60 2.3 General Purpose Transceiver (GPT) Overview The GPT transceiver is a self-contained unit. It can be mounted anywhere onboard the vessel. It is recommended to mount the GPT as close to the transducer(s) as possible in order to minimise the electrical interference into the transducer cable.
Hardware installation 2.4 GPT Cabinet Overview The GPT Cabinet is a steel enclosure used to house one or two General Purpose Transceivers (GPT). The cabinet provides IP55 protection. All electrical connections made to the cabinet are carried out on tag blocks inside the unit. The cabinet is easily mounted with the four brackets supplied. Procedure The cabinet is fixed to the bulkhead with four bolts.
Simrad EK60 2.5 Processing Unit (computer) Power supply A stable power supply is necessary to provide power to the system’s computer(s) and other components. An uninterrupted power supply (UPS) is recommended to supply power to the computer(s) to protect against power spikes or failure which can damage their electronic components and ability to retrieve valuable stored data.
Hardware installation 2.6 Display Any standard computer display may be used on the echo sounder computer. However, the standard delivery comprises a liquid crystal display (LCD) unit, which is available in different sizes. A separate manual is included with each display delivery. Refer to this manual for more information about installation and use of the display unit.
Simrad EK60 2.7 Printer Introduction Any Microsoft Windows compatible printer may be connected to the EK60 Processor Unit. The connection is made with a standard Centronics type parallel cable. Hardware installation Refer to the applicable printer documentation for hardware installation. Make sure that the printer is securely mounted to withstand the shock, vibrations and movements experienced on a ship.
Hardware installation 2.8 Ethernet Data Network The echo sounder computer and the GPT transceiver communicate via a local area network interface of the Ethernet type. The original Ethernet version was standardised in 1978 by Xerox Corporation, Intel Corporation and Digital Equipment Corporation.

It is relatively immune to electromagnetic interference and cross-talk.
Transducer installation 3 TRANSDUCER INSTALLATION 3.1 Transducer location 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. Go deep The upper water layers of the sea contain a myriad of small air bubbles created by the breaking waves. In heavy seas the uppermost 5 to 10 metres may be air-filled, with the highest concentrations near the surface.
Simrad EK60 layer is thin underneath the forward part of the vessel, and increases in thickness as it moves towards aft. 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.
Transducer installation 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. Vessel heave Heave is the up and down movement of the vessel.
Simrad EK60 Summary 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 6.
Transducer installation 3.2 Ways of mounting the transducer Inclination of the transducer face Incline the transducer face approximately 3 degrees, so that the flowing water meets it directly. This assures laminar water flow. Mounting screws should not be extruding from the transducer, and the space around the screws could be filled with a compound or a locking ring.
Simrad EK60 External mount Some transducers have a streamlined housing, designed for installation outside the hull. Steel tube Stuffing tube Washer Rubber gasket Cable service loop (CD3005) Packing nipple Fairing Air outlet 3° Transducer Bedding compound Figure 8 External mounting on steel hulls A fairing, made by the shipyard, is placed between the transducer and the hull, to adapt for the deadrise angle of the hull.

Simrad EK60 Transducer blister Other transducers are designed for installation into the hull or in a blister. In general, a blister installation is the recommended method. It brings the transducer below the boundary layer. A blister is illustrated below. Cable service loop Air outlet Min.
Transducer installation The transducer cable penetrates the hull in a stuffing tube, see the figure above. Leave an adequate loop of the cable behind the transducer for easy mounting or removal of the transducer.
Simrad EK60 In a box keel (CD3008) Vessels with a box keel may use this for transducer installation. The box keel is already the deepest part of the vessel. If the box keel is too narrow to accommodate the transducer, it can be widened, either symmetrically or to one side only. In the last case the installation could also be described as a blister merged into the keel. The figure below illustrates a symmetrical box keel installation.
Transducer installation Retractable transducer Retractable hull units are commonly used for horizontal looking sonars. When not in use, the transducer is retracted into a trunk. The retractable hull unit is more expensive than a blister, but on vessels having a hull where it is difficult or impossible to install a blister, it may be worth-while. A retractable hull unit with transducer is shown below.
Simrad EK60 Centre board The use of a centre board with the purpose of stabilising the vessel is well known. A centre board is also a superior platform for transducers. Such instrument keels have been built, mainly on research vessels, with a length of 3 m, protruding also 3 m below the hull, see the figure below. At that depth, the water is free of air bubbles up to very high sea states. The vessel is then able to perform reliable acoustic measurements in open sea a larger part of the year.
Transducer installation Flush mounting in a steel tank Flush mounting is used on very large vessels with a hull so deep that no air bubbles are found below the hull, and on vessels operating in shallow harbours or waters, where a protruding blister can not be accepted. The standard procedure for flush mounting on a steel vessel is to weld a steel tank inside the hull, and mount the transducer into this tank. As for a blister, the interior of the tank must be filled with water.
Simrad EK60 Behind a protective acoustic window Vessels operating in arctic waters need special attention on transducer installation. Floating blocks of ice may damage even a flush mounted transducer face. For this situation Simrad offers ‘’arctic tanks’’ in different sizes. The transducer shown in the figure below is mounted inside the tank behind a strong acoustic window which could be made of polycarbonate. The tank is oil filled.
Transducer installation Inside the hull An installation of the transducer inside the hull, and sounding through the hull, requires a good acoustic contact between the transducer face and the hull. Build a tank around the transducer and fill it with a liquid. Oil used in hydraulic systems is a well suited liquid for this purpose. It contains no gas bubbles and is non-corrosive. The tarnsducer can be mounted inside the hull. A substantial loss must be expected when the sound passes through the hull.
Simrad EK60 3.3 Cable in steel conduit It is strongly recommended to lay a steel conduit from the transducer to the echo sounder transceiver, and draw the transducer cable through the conduit. There are two reasons for this procedure. • First, it will make it easier at a later stage to replace the transducer. • Second, noise and interference from other electrical equipment is greatly reduced. With a steel conduit the installation satisfies the EU regulations for EMC interference.
Transducer installation The tube should be unbroken and watertight from the transducer to above the water line. From there, openings or a junction box can be installed to facilitate drawing of the cable, or to add a cable extension. However, the tube should act as a continuous electrical screen all the way and be connected to the transceiver chassis. Tube dimensions: • minimum 35 mm inner diameter • minimum 6 mm wall thickness (4.5 mm if galvanised).
Simrad EK60 3.4 Handling and maintenance Do not lift the transducer by the cable. Some transducers are delivered with a cover plate on the face for protection during transport. Let this plate stay on as long as possible, but do not forget to remove it before the vessel goes into the sea. An anti-fouling paint may be applied to the transducer face. Because some paint types may be aggressive to the polyurethane in the transducer face, please consult Simrad’s list of approved paints on the next page.
Transducer installation 3.5 Approved anti-fouling paints This is Simrad’s list of approved antifouling paints on polyurethane transducer housing. From Jotun Paints, Sandefjord Norway: • Antifouling Seamate HB 33 • Antifouling Seamate HB 66 • Antifouling Seamate HB 99 • Racing • Non-stop From International Paints: • Intersleek tie coat + 425 FCS - BXA386/BXA390/BXA391 Grey - HKA563/HKA570/HKA571 Yellow Mix BXA386, BXA390 and BXA391 first, then apply. When dry, mix HKA563, HKA570 and HKA571, apply.

Cable layout 4.3 External interfaces Overview The computer provides one or more multi purpose RS-232 ports (9-pin male D-connector) for external interfacing at its rear. On the Simrad EK60, these are used for: • NMEA navigation receiver input • Depth telegram output • ITI (Integrated Trawl Instrumentation) communication • Purse seine • Motion sensor input • Synchronization An analogue heave, roll and pitch sensor may be connected directly to the Auxiliary connector of the nearest transceiver.
Simrad EK60 Connect the ITI to a free RS232 port. Only the receive signal wire (Rx, pin 2), the transmit signal wire (Tx, pin 3) and the ground wire (pin 5) need to be connected. Maximum cable length is approximately 10 meters. Heave sensor A heave sensor with an analogue output is connected directly to the Auxiliary connector. The positive heave input signal (pin 3) is connected to the sensor output terminal.
Cable layout 4.4 External triggering Overview Whenever more than one hydroacoustic system (echo sounder or sonar) is installed on a vessel, interference may occur. To avoid this, the systems may either be connected to a common synchronization system, or one of the acoustic systems may be defined as a “master”. The EK60 echo sounder include interface for remote transmit synchronisation.
Simrad EK60 Connect the ground wire to one of the Ground pins (18-22). Note If the EK60 system comprises more than one GPT unit, the external trigger must be connected in parallel to every GPT. Synchronization using a serial port When the EK60 system shall be synchronized using a serial port, a standard connection is used, but with only the CTS and RTS signal applied. Setting up the EK60 as master or slave is made in the ER60 Ping Control dialogue.

Simrad EK60 Transducer(s) The cables described in this chapter are used to connect the General Purpose Transceiver (GPT) to one or more transducers. The following transducer types may be used: • Single frequency, split beam → The plug housing is shown on page 79. For the majority of the transducers, the cables are supplied from the manufacturer. These are normally physically fastened to the transducer.
Cable layout Single frequency, split beam The drawing shows how to connect a single frequency, split beam transducer to the system. Note: 1) All transducer cables must be run in steel conduits. Use flexible conduit closer to the transceiver. 2) Cable shields must be connected to the plug housing. 3) Cable shields must not be connected to ship's ground in the junction box.
Simrad EK60 Cable colours on split beam transducers Note that the cables from the transducer may be supplied in different colours. The following colours may be used: 78 Channel Shown in W802--3 Alt.

Simrad EK60 4.6 Basic cabling requirements Cable trays All permanently installed cables associated with the system must be supported and protected along their entire lengths using conduits and/or cable trays. The only exception to this rule is over the final short distance (max. 0.5 metre) as the cables run into the cabinets/units to which they are connected. These short unsupported lengths are to allow the cabinets to move on their shock mounts, and to allow maintenance and replacements.
Cable layout Radio Frequency interference All cables that are to be permanently installed within 9 m (30 ft) of any source of Radio Frequency (RF) interference such as a transmitter aerial system or radio cabin, must, unless shielded by a metal deck or bulkhead, be adequately screened by sheathing, braiding or other suitable material. In such a situation flexible cables should be screened wherever possible.
Simrad EK60 Metallic casings, pipes and conduits must be grounded, and when fitted with joints these must be mechanically and electrically grounded. Cable connections All cable connections are shown on the applicable cable plan and interconnection diagrams. Where the cable plan shows cable connections outside an equipment box outline, the connections are to be made to a plug or socket which suits the plug or socket on that particular item of equipment.
Cable layout 4.7 Cable gland assembly procedure Purpose 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. Note There are many different types of cable gland on the market.
Simrad EK60 Note The cable’s outer insulation will extend into the cable gland to a point approximately 5 mm outside the outer surface of the cabinet wall into which the cable gland is secured. 4 5 Taking care not to damage the screening, carefully remove the outer insulation from the required cable length. Leaving an appropriate length of the screen exposed from the insulation, cut off the remainder.
Cable layout Figure 26 Multi-diameter modules (example) After the frame has been mounted, the cables can be pulled through, and in most cases the opening will be large enough even to accept the plugs on the cables. Figure 27 Multi-diameter system - Principal procedure Once the cables are through, each cable is secured with a square module, which is adjusted to fit the cable’s outer diameter.
Simrad EK60 When the required number of modules are installed, the assembly is tightened with a compression unit. This system is available with a large number of various modules and compression units, and it will also comply to screening and EMC requirements. Figure 28 Multi-diameter system - The finishied assembly Standard type Note 86 1 Ensure that all the cables to be connected, are completely isolated from any power sources.
