2.2 Product overviewEvolution is a system of electronic components thatgive you autopilot control of your vessel’s steeringsystem.In conjunction with a compatible Autopilot controller,the Evolution components enable you to directlycontrol the vessel’s steering system and providenavigation commands, such as navigating topre-determined tracks and waypoints for example.The Evolution system provides a number of featuresto ensure ease of installation and minimal setup:• Flexible mounting options — The EV sensorcan be mounted horizontally on a flat deck oralternatively on a bracket, for mounting on a mast,wall or other vertical surface.

Note: The arrow on the front of the EV sensormust be parallel with the centerline of thevessel and pointing towards the vessel’s bow.

• Simple connections — all Evolution systemcomponents are connected to a single SeaTalkng®backbone.

• High accuracy — accurate course-keeping, towithin +/- 2 degrees, in all conditions.

• Built-in heading and attitude sensor — noadditional fluxgate compass required.

• Automatic setup— no calibration required. TheRudder Gain, Rudder Damping, Counter Rudder,and compass calibration settings required byexisting autopilots are no longer necessary

The Evolution system consists of the followingcomponents:Component PurposeEV-1 unit AHRS (AttitudeHeading Reference Sensor)

The primary heading sensorand course computer,incorporating an attitude9-axis sensor. This sensorreplaces the fluxgatecompass typical in existingautopilot systems.

ACU (Actuator Control Unit) Houses the main power anddrive electronics for directconnection to a vessel’ssteering system.

Document and product information 11


Required additional componentsTo complete your autopilot system, you will need thefollowing components and data sources in additionto the Evolution components.Essential:• Compatible autopilot controller (See: 3.4Compatible autopilot controller).

• Drive unit appropriate for your vessel and EvolutionEV and ACU units (See: 3.5 Drive unit).

• ACU power cable (not supplied).• SeaTalkng® backbone.Recommended:• Compatible speed data source. The autopilot usesspeed data when making calculations relatingto navigation. As a minimum, this informationmust come from a GNSS receiver providing SOG(Speed Over Ground) data, or ideally from adedicated speed sensor.

• Compatible wind data source (only required forsailing vessels). The autopilot uses wind vane datato steer relative to a specified wind angle. Thisdata must come from an analog wind transducerconnected to the SeaTalkng® backbone.

• Rudder angle sensor. To ensure optimum autopilotperformance, it is highly recommended that arudder reference unit is used.

Note: The system components listed aboveare “recommended” because they help toprovide optimum performance for autopilotsystems when used in conjunction with the“essential” components listed. However, these“recommended” components are not included inall autopilot products or system packs. Consult theRaymarine website or your local dealer for a fulllist of the components included with your autopilotsystem.

Optional:• Position data source – The autopilot uses positiondata when following routes and calculating theoptimum course to steer. This data is usuallysupplied by a GNSS receiver on the SeaTalkng®backbone.

SeaTalkng®SeaTalkng® (Next Generation) is an enhancedprotocol for connection of compatible marineinstruments and equipment. It replaces the olderSeaTalk and SeaTalk2 protocols.SeaTalkng® utilizes a single backbone to whichcompatible equipment connect using a spur. Dataand power are carried within the backbone. Devicesthat have a low draw can be powered from thenetwork, although high current equipment will needto have a separate power connection.SeaTalkng® is a proprietary extension to NMEA 2000and the proven CAN bus technology. CompatibleNMEA 2000 and SeaTalk and SeaTalk2 devices canalso be connected using the appropriate interfacesor adaptor cables as required.

Multiple data sources (MDS) overviewWhen a system includes multiple instances of adata source the preferred data source is selectedautomatically. The systems preferred source may notbe your preferred source, or if you are experiencing adata conflict you can manually select your preferreddata source.MDS enables you to choose a preferred source forthe following data types:• GNSS Position• GNSS Datum• Time & Date• Heading• Depth• Speed• WindThis exercise would usually be completed as partof the initial installation, or when new equipment isadded.For MDS to be available all products in the systemthat use the data sources listed above, must beMDS-compliant. The system will report any productsthat are NOT MDS-compliant. It may be possibleto upgrade the software for these products, tomake them compliant. Visit the Raymarine website(www.raymarine.com) to obtain the latest softwarefor your products.If MDS-compliant software is not available for theproduct and you do NOT want to use the systemspreferred data source, you must remove anynon-compliant product from the system. You shouldthen be able to select your preferred data source.

Note: Once you have completed setting up yourpreferred data sources, you may be able to addthe non-compliant products back into the system.

Multiple data source exceptionsWith the Evolution system, there are a number ofimportant exceptions to the handling of multiplesources of certain types of data.Specifically:• Heading data — If a non-Evolution source ofheading data is designated by the user, theEvolution system components will combine thisheading data with its own gyro and accelerometerdata, and then use the improved heading data.This combined heading data will also be availableto other equipment on the SeaTalkng® bus.

• Rudder angle data — Where there are multiplesources of rudder reference information, theEvolution system components will ignore rudderangle inputs from any rudder reference units thatare NOT connected directly to the ACU.

Compass safe distanceTo prevent potential interference with the vessel'smagnetic compasses, ensure an adequate distanceis maintained from the product.When choosing a suitable location for the productyou should aim to maintain the maximum possibledistance from any compasses. Typically this distanceshould be at least 1 m (3 ft) in all directions. Howeverfor some smaller vessels it may not be possible tolocate the product this far away from a compass. Inthis situation, when choosing the installation locationfor your product, ensure that the compass is notaffected by the product when it is in a powered state.

EMC installation guidelinesRaymarine equipment and accessories conform tothe appropriate Electromagnetic Compatibility (EMC)regulations, to minimize electromagnetic interference

between equipment and minimize the effect suchinterference could have on the performance of yoursystemCorrect installation is required to ensure that EMCperformance is not compromised.

Note: In areas of extreme EMC interference,some slight interference may be noticed on theproduct.Where this occurs the product and thesource of the interference should be separated bya greater distance.

For optimum EMC performance we recommendthat wherever possible:• Raymarine equipment and cables connected toit are:– At least 1m (3ft) from any equipment transmittingor cables carrying radio signals e.g. VHF radios,cables and antennas. In the case of SSB radios,the distance should be increased to 7 ft (2 m).

– More than 2m (7ft) from the path of a radarbeam. A radar beam can normally be assumedto spread 20 degrees above and below theradiating element.

• The product is supplied from a separate batteryfrom that used for engine start. This is important toprevent erratic behavior and data loss which canoccur if the engine start does not have a separatebattery.

• Raymarine specified cables are used.• Cables are not cut or extended, unless doing so isdetailed in the installation manual.

Note: Where constraints on the installationprevent any of the above recommendations,always ensure the maximum possible separationbetween different items of electrical equipment, toprovide the best conditions for EMC performancethroughout the installation

Cables and connections 25

4.1 General cabling guidance

Cable types and lengthIt is important to use cables of the appropriate typeand length• Unless otherwise stated use only standard cablesof the correct type, supplied by Raymarine.

• Ensure that any non-Raymarine cables are of thecorrect quality and gauge. For example, longerpower cable runs may require larger wire gaugesto minimize voltage drop along the run.

Routing cablesCables must be routed correctly, to maximizeperformance and prolong cable life.• Do NOT bend cables excessively. Whereverpossible, ensure a minimum bend diameter of 200mm (8 in) / minimum bend radius of 100 mm (4 in).

• Protect all cables from physical damage andexposure to heat. Use trunking or conduit wherepossible. Do NOT run cables through bilges ordoorways, or close to moving or hot objects.

• Secure cables in place using tie-wraps or lacingtwine. Coil any extra cable and tie it out of the way.

• Where a cable passes through an exposedbulkhead or deckhead, use a suitable watertightfeed-through.

• Do NOT run cables near to engines or fluorescentlights.

Always route data cables as far away as possiblefrom:• other equipment and cables,• high current carrying AC and DC power lines,• antennae.

Strain reliefEnsure adequate strain relief is provided. Protectconnectors from strain and ensure they will not pullout under extreme sea conditions.

Cable shieldingEnsure that all data cables are properly shieldedthat the cable shielding is intact (e.g. hasn’t beenscraped off by being squeezed through a tight area).

4.2 EV connections

Connections overview — EV-1 andEV-2

1. SeaTalkng®2. DeviceNet

Important:The DeviceNet port is for use with the EV-2 only.Do NOT connect this port on the EV-1 unit.

Connecting SeaTalkng® cables

1. Rotate the locking collar on the unit to theunlocked position.

2. Ensure the cable’s connector is correctly oriented.3. Fully insert the cable connector.4. Rotate locking collar clockwise (2 clicks) until it is

in the locked position.

26

Power connection — EV-1The power for the EV-1 unit is provided by theSeaTalkng® backbone.• The EV-1 unit must be connected to a spurconnection on the SeaTalkng® backbone.

• SeaTalkng® requires ONE 12 V dc power source.This can be provided by:– A battery– An Evolution ACU–200, ACU-300 or ACU-400providing power to the same SeaTalkng®backbone.

If your vessel has a 24 V supply a suitable voltageconvertor is required.


SeaTalkng® power connection pointSmall systemsIf the backbone length is 60 m (197 ft) or less, thepower connection point may be connected at anypoint in the backbone.

Large systemsIf the backbone length is greater than 60 m (197 ft),the power connection point should be connected ata point that creates a balanced current draw fromeach side of the backbone. The Load EquivalencyNumber (LEN) is used to determine the powerconnection point for the system.

In the example above the system has an overall LENof 10, so the optimum connection point would be tohave 5 LEN either side of the connection point.

In-line fuse and thermal breaker ratingsThe SeaTalkng® network’s power supply requires anin-line fuse or thermal breaker to be fitted.In-line fuse rating Thermal breaker rating5 A 3 A (if only connecting one

device)

Note:The suitable fuse rating for the thermal breakeris dependent on the number of devices you areconnecting. If in doubt consult an authorizedRaymarine dealer.

Power distribution — SeaTalkng®Recommendations and best practice.• Only use approved SeaTalkng® power cables. DoNOT use a power cable designed for, or suppliedwith, a different product.

• See below for more information on implementationfor some common power distribution scenarios.

Important:When planning and wiring, take into considerationother products in your system, some of which (e.g.sonar modules) may place large power demandpeaks on the vessel’s electrical system.

Note:The information provided below is for guidanceonly, to help protect your product. It coverscommon vessel power arrangements, but doesNOT cover every scenario. If you are unsure howto provide the correct level of protection, pleaseconsult an authorized Raymarine dealer or asuitably qualified professional marine electrician.

Implementation — direct connection to battery• SeaTalkng® power cables may be connecteddirectly to the vessel's battery, via a suitably ratedfuse or breaker.

• You MUST fit a suitably rated fuse or breakerbetween the red wire and the battery’s positiveterminal.

• Refer to the inline fuse ratings provided in theproduct’s documentation.


• If you need to extend the length of the powercable, ensure you use suitably rated cable andthat sufficient power (12 V dc) is available at theSeaTalkng® backbone’s power connection.

A Battery connection scenario A: suitable for a vessel witha common RF ground point. In this scenario, if yourproduct’s power cable is supplied with a separate drainwire then it should be connected to the vessel’s commonground point.

B Battery connection scenario B: suitable for a vesselwithout a common grounding point. In this case, if yourproduct’s power cable is supplied with a separate drainwire then it should be connected directly to the battery’snegative terminal.

Implementation — connection to distributionpanel

• Alternatively, the SeaTalkng® power cable may beconnected to a suitable breaker or switch on thevessel's distribution panel or factory-fitted powerdistribution point.

• The distribution point should be fed from thevessel’s primary power source by 8 AWG(8.36 mm2) cable.

• Ideally, all equipment should be wired to individualsuitably-rated thermal breakers or fuses, withappropriate circuit protection. Where this is notpossible and more than 1 item of equipmentshares a breaker, use individual in-line fusesfor each power circuit to provide the necessaryprotection.

• In all cases, observe the recommendedbreaker / fuse ratings provided in the product’sdocumentation.

• If you need to extend the length of the powercable, ensure you use suitably rated cable andthat sufficient power (12 V dc) is available at theSeaTalkng® backbone’s power connection.

Important:Be aware that the suitable fuse rating for thethermal breaker or fuse is dependent on thenumber of devices you are connecting.

More informationIt is recommended that best practice is observed inall vessel electrical installations, as detailed in thefollowing standards:• BMEA Code of Practice for Electrical andElectronic Installations in Boats

• NMEA 0400 Installation Standard• ABYC E-11 AC & DC Electrical Systems on Boats• ABYC A-31 Battery chargers and Inverters• ABYC TE-4 Lightning Protection

Sharing a breakerWhere more than 1 piece of equipment shares abreaker you must provide protection for the individualcircuits. E.g. by connecting an in-line fuse for eachpower circuit.

Grounding — Dedicated drain wirerequiredThis product includes a dedicated drain conductor(screen) for connection to a vessel's RF groundpoint.It is important that an effective RF ground isconnected to the unit. The unit can be groundedby connecting the drain conductor (screen) to thevessel's RF ground point. On vessels without anRF ground system the drain conductor (screen)should be connected directly to the negative batteryterminal.The dc power system should be either:• Negative grounded, with the negative batteryterminal connected to the vessel's ground; or

• Floating, with neither battery terminal connectedto the vessel's ground.

If several items require grounding, they may firstbe connected to a single local point (e.g. withina switch panel), with this point connected via asingle, appropriately-rated conductor, to the vessel’scommon RF ground point.

ImplementationThe preferred minimum requirement for the path toground is via a flat tinned copper braid, with a 30Arating (1/4inch) or greater. If this is not possible, anequivalent stranded wire conductor maybe used,rated as follows:• for runs of <1m (3 ft), use 6mm2 (#10 AWG) orgreater.

• for runs of >1m (3 ft), use 8 mm2 (#8 AWG) orgreater.

In any grounding system, always keep the length ofconnecting braid or wires as short as possible.

Rudder reference connectionA rudder reference sensor unit can be connected tothe ACU to provide rudder angle information to theautopilot system.The connection of a rudder reference unit is highlyrecommended, to help ensure optimum autopilotperformance.

Note: A rudder reference sensor is not includedwith all autopilot products or system packs.Consult the Raymarine website or your local dealerfor a full list of the components included with yourautopilot system.

A rudder reference unit converts its movementinformation to rudder angle in +/- degrees.Certain environmental conditions such ascross-current can cause the autopilot system tosteer persistently to port or starboard, even whenthe rudder is centered. With a rudder reference unitconnected to your autopilot system, you can use anautopilot control head to specify an offset angle in +/-degrees to compensate for inaccurate rudder angleinformation caused by such conditions.The more accurate the rudder angle information, themore accurately the autopilot system can keep to acorrect course.The rudder reference unit connection to the ACUconnection panel is shown below.

B Blue Clutch Negative (–)connection

Motor power outputACU–200 ACU-40015 A (maximum continuousoutput)

30 A (maximum continuousoutput)

Note:The motor output has full short-circuit andover-current protection. Should either of the motoroutput connections be shorted to ground, thereshould be no permanent damage to the autopilot.

Clutch power outputACU–200 ACU-400Up to 2 A continuous at 12 Von 12 V and 24 V systems.

• Up to 4 A continuous at12 V on 12 V systems.



Note:The use of a clutch drive will have an impacton the amount of electrical current available tothe SeaTalkng® backbone. On 24 V systems,there is an 8 A / 12 V maximum supply for theSeaTalkng® backbone and clutch drive combined.For example, if the clutch requires 4 A, theSeaTalkng® supply can only deliver 4 A to the restof the backbone.

Note:The clutch output on all ACU variants has fullshort-circuit and over-current protection. Shouldeither of the clutch output connections be shortedto ground, there should be no permanent damageto the autopilot.

Clutch voltage switch

If the drive has a separate clutch connection, youmust ensure that the clutch voltage switch on theACU is set correctly to suit the connected drive.

Important:To avoid potential damage to equipment, ensurevoltage selector switch is set to the correct setting.The clutch voltage may be different from that of thedrive itself, for example the range of both 12 V and24 V Raymarine drives all have a 12 V clutch. If indoubt, consult your local dealer.

Solenoid (drive) and bypass valveconnection - ACU-300Constant Running Pump (solenoid) drives connectto the connection panel of the ACU-300.

Solenoid drive connection

1. Electronic steering / jog lever (if required)2. Back-feed protection diodes (if using an

electronic steering or jog lever)3. Solenoid out4. Solenoid return5. Solenoid valves (with diodes across spool

valves)

Note:If an electronic steering or jog lever is used, fitdiodes (suggested type: 1N4004) in-line with thesolenoid outputs to prevent back-feeding the ACU.

SeaTalkng® power switch (ACU-200, ACU-300,ACU-400 only)The ACU-200, ACU-300, ACU-400 can providepower to the SeaTalkng® backbone. This willprovide power to certain equipment connected to thebackbone (e.g. SeaTalkng® autopilot control headand instrument displays).Set the SeaTalkng® power switch on the connectorpanel to the appropriate position:• ON — The ACU-200, ACU-300, ACU-400 willsupply power to the SeaTalkng® backbone.

ImportantEnsure that there are no otherpower feeds connected into the backbone.

• OFF — The ACU-200, ACU-300, ACU-400 willNOT supply power to the SeaTalkng® backbone.Ensure that there is a separate power feed to theSeaTalkng® backbone.

Important:Use correct fuse. The fuse supplying theSeaTalkng® system MUST be rated as per thevalue shown on the ACU connector panel.

Sleep switch connection — ACU-200,ACU-300, ACU-400A Sleep switch disables the operation of theautopilot while retaining any power supplied to theSeaTalkng® backbone.

The switch and associated cable are not suppliedwith the Evolution system. Contact your dealer ordrive manufacturer for more information.

Rudder reference connectionA rudder reference sensor unit can be connected tothe ACU to provide rudder angle information to theautopilot system.The connection of a rudder reference unit is highlyrecommended, to help ensure optimum autopilotperformance.

Note: A rudder reference sensor is not includedwith all autopilot products or system packs.Consult the Raymarine website or your local dealerfor a full list of the components included with yourautopilot system.

A rudder reference unit converts its movementinformation to rudder angle in +/- degrees.Certain environmental conditions such ascross-current can cause the autopilot system tosteer persistently to port or starboard, even when

the rudder is centered. With a rudder reference unitconnected to your autopilot system, you can use anautopilot control head to specify an offset angle in +/-degrees to compensate for inaccurate rudder angleinformation caused by such conditions.The more accurate the rudder angle information, themore accurately the autopilot system can keep to acorrect course.The rudder reference unit connection to the ACUconnection panel is shown below.

6.3 AlarmsAlarms are raised by the autopilot system to alert you to mechanical and electrical conditions requiringyour attention.The Evolution components transmit alarm alerts on the SeaTalkng® network for display on autopilotcontrollers and MFDs, along with an audible alert. The Evolution components stop raising an alarm whenthe alarm condition ceases or the alarm is acknowledged on the autopilot controller or MFD. If the alarm issafety-critical it will be raised again after a timed delay.Unless otherwise stated in the table below, you should respond to alarms by selecting OK or Acknowledgeon your autopilot controller or MFD.Alarm Message Possible causes SolutionOFF COURSE Autopilot has deviated from planned

course.Check your vessel position and ifnecessary take manual control to steerthe vessel back on course.

WIND SHIFT Autopilot is unable to maintain navigationto the current wind angle.

LOW BATTERY Power supply voltage has dropped belowacceptable limits. Caused by low batteryvoltage or voltage drop at the ACUunit (EV-1 systems only), due to poorconnections or inadequate wiring.

Acknowledge the alarm and then start theengine to recharge the battery. If problempersists, check wiring connections andthat the quality and gauge of wiring isadequate for the current draw of the driveunit.

LARGE XTE Large cross-track error. The autopilothas deviated more than expected froma planned course.

Check your vessel position and ifnecessary take manual control to steerthe vessel back on course.

CU DISCONNECTED The autopilot control head has beendisconnected.

• Check the physical cables andconnections between the autopilotcontrol head and the SeaTalkng®system. Also between the EV-1 / EV-2and the SeaTalkng system.

• If the autopilot control head isconnected via a SeaTalk® toSeaTalkng® converter, check theconverter is using the latest softwareversion.

AUTO RELEASE Possible fault with rudder reference unit.Alternatively, if your autopilot systemincludes a stern I/O drive, you have takenmanual control of the steering while thepilot is in Auto mode.

• Check rudder reference unitconnections.

• For systems using the Volvo PentaEVC drive interface unit, check theunit is operating correctly.

WAYPOINT ADVANCE The autopilot has steered the vessel tothe current waypoint.

Acknowledge the turn to the nextwaypoint.

DRIVE STOPPED • Motor / steering has not moved within20 seconds of a course changecommand.

• The autopilot is unable to turn therudder (either because the weatherload on the helm is too high, or if therudder position sensor has passedbeyond the preset rudder limits orrudder end-stops.

• Autopilot resets due to an externalevent (such as use of the sleep switch,or faulty wiring causing the autopilotcomponents to power cycle).

• Autopilot resets due to software error.

• Check the rudder reference unit hasbeen installed correctly to reflect thelimits and end-stops of the vessel’srudder system.

• For EV-1 systems, check ACU driveoutput voltage and drive and clutchvoltage output (if applicable).

• For EV-1 systems, check allconnections to ACU.

• Check all connections to drive unit.• Check that the drive unit operates and

is not stalled.• Check steering system is secure.
