System • CyScan Sensor Part Names (page 8) l 5 Welcome Welcome to the CyScan (Dashboard) Operator's Guide. It has been written for operators of the CyScan system that use the CyScan Dashboard operator interface rather than the legacy CyScan Console. Getting Started (see page 10) explains the basics that you’ll need to know before using the CyScan system for the first time. The CyScan Dashboard can be configured at installation for either a single-Dashboard serial system or a multi-Dashboard Ethernet system. The majority of the sections in this guide apply equally for serial or Ethernet configured systems and explain how to perform the various tasks necessary to operate the system and use it for tracking. These include Tracking Basics (see page 22) and Single and Multi-Target Tracking (see page 29), Support Information (see page 47) and Troubleshooting (see page 53). The section titled Ethernet (Multi-Console) CyScan Systems (see page 44) gives information specific to an Ethernet configured system. Note that the introduction of the Dashboard constitutes a significant change in the CyScan operator interface in comparison with the legacy console. There are also likely to be further improvements to the Dashboard in subsequent releases. Whilst we endeavour to describe its functionality correctly in this document, we do not guarantee that it exactly represents the version of Dashboard that you are running. l 6 System Overview CyScan is a high accuracy laser sensor which provides positional information to allow automated approach and/or station keeping relative to a structure or vessel. The system requires one or more reflective targets to be attached to the sides of the structure or vessel. CyScan is designed to be semi-portable and straightforward to operate. In use, the CyScan system key elements are: CyScan Sensor, with integrated Power Supply Unit, which is mounted on the • The vessel (typically on the wheel-house) as required. CyScan Dashboard. A monitoring and control software application running within • The Microsoft Windows on a Type 2 Marine Processor or other computer. This provides CyScan emits eye-safe infra-red light and detects the reflections back from retro-reflective targets. Targets are mounted on designated structures or vessels. They consist of strips of a high performance reflective tape mounted on a flat or a cylindrical support. The accurate range and bearing of one or more targets is measured by CyScan and used to calculate the exact position of the CyScan vessel relative to the target structure or vessel. This positional information is displayed on the Dashboard screen and automatically transmitted to the vessel's DP system. Structure or Vessel TM the DP operator with full status information and control of the system and the data stream being fed to the DP system.

Ensure that the CyScan sensor is powered on. 2. Double-click on the CyScan Dashboard icon. (Or run the CyScan Dashboard application from Start > All Programs > CyScan Dashboard x.xx). 3. The Dashboard display screen will appear. If the sensor is currently suspended, the main part of the screen will be greyed out. Click on the Resume button in the side bar in order for the sensor to begin scanning and for the results to be displayed on the screen. If the sensor was already scanning, any targets in view will be displayed straight away.

Suspend & Exit—Places the sensor into the same ‘sleep mode’ as the suspend command (discussed above) and also closes the CyScan Dashboard program. The Guidance Home is disabled on a Master Dashboard whilst tracking, but is enabled on a Slave. Master or Serial Dashboard Slave Dashboard l 11 Screen Layout The CyScan Dashboard screen is split into three distinct sections, these are: 1. Main Screen and Bird's • Eye View (BEV) (see page 13) Bar (see page 15) • 2.3. Side • Menu Pane (see page 18) 2 1 3 l 12 Screen Layout (Continued) Main Screen and Bird's Eye View (BEV) The centre of the circular BEV represents the CyScan sensor and it shows the relative positions of the CyScan vessel and any detected reflections. CyScan Vessel The length and breadth of the vessel and the offsets and orientation of the CyScan sensor within it can be entered on the Vessel Parameters pane (see Installer's Guide) so that the vessel image is correctly scaled and positioned on the BEV. System Status Data Logging Indicator Blanking Zone Drag Handles CyScan Vessel Range Circles Hotkeys Tab Blanking Zone Blanking Zone The Blanking Zone is the sector within each revolution of the sensor rotor where the laser is switched off. It is typically set to correspond to the area in which the beam would strike portions of the vessel structure. The blanking zone can be adjusted using the Drag Handles, to suit different situations (See Blanking Zones on page 23). Reflection Images Bearing Tag Range Circles The Range Circles act as a visual guide to show the distance between the CyScan vessel and the detected reflections. Distances are shown in metres from the CyScan sensor. Use the Zoom Control to change the scale of the display. (See page 14). Brightness Bar Radial Markers Zoom Control Optimum Zoom Button 'Hotkeys' Tab Radial Markers These form an angular scale in degrees, clockwise around the circumference of the BEV. Zero is defined by the bow of the vessel, or by a line between the primary and secondary targets, or by a manual alignment of vessel heading, depending upon the selected tracking mode, DP format and display coordinates. Some elements when clicked (or tapped on a touch screen), will provide quick access to related system functions. (See Location-Sensitive Shortcuts on page 17) l 13 Screen Layout (Continued) Reflection Images Reflections received by the sensor are displayed as yellow circles. For tracking you must select the reflection(s) that correspond to the physical target(s) to be used. During multi-target tracking, white boxes are drawn around the selected reflections to indicate a strong association with the target (i.e. the system is receiving good data and is confident of the target position). A red box appears around a selected reflection during tracking if the system has lost sight of the target, or there is insufficient data being received to use it for tracking. click or tap on the area of the Primary Status Display. Brightness Bar Indicates the brightness level of the primary (or only) reflection being tracked, along with the rejection threshold. Bearing and Heading Tags These are displayed on the Radial Marker when the system is in tracking mode, to indicate the bearing of the primary (or only) target and the vessel's heading. The visibility of these two elements depends on the DP format selected and which coordinate system is being used to display the positional information (see Positional Display Modes on page 32). Data Logging Indicator This symbol is displayed when data is being logged to disk. During a tracking operation the symbol is steady and when manual logging is in progress it flashes. Zoom Control Click on the left-hand side of the control (marked '-') to zoom out of the display and on the right-hand side ('+') to zoom in. Click on the triangular Optimum Zoom Button to set the scale such that the longest range reflection is positioned about three-quarters of the way from the centre of the BEV to its circumference. System Status This consists of two fields: Primary The primary part of the status display is in the upper-right corner of the Main Pane. It indicates the current status of the system (running, suspended or error). Click or tap on the area of the Primary Status Display to display a secondary status display message. Secondary The secondary status display is located in the lower right corner of the Main Pane (beneath the zoom function). It supplements the primary display by indicating the system communication status. The secondary status display is normally hidden, activated by a l 14 Screen Layout (Continued) Side Bar The Side Bar, the black pane to the left of the BEV, contains control and display components in addition to the coordinates pane. Note: Coord = Coordinate Some of the above elements are also 'shortcuts,' providing quick access to their corresponding menu panes (see Location-Sensitive Shortcuts on page 17). l 15 Screen Layout (Continued) Hidden Links and Buttons Selecting the hotkeys tab on the right-hand side of the Bird's Eye View (BEV) activates the 'CyScan Hotkeys' menu. The following keys - and the corresponding buttons on the CyScan Hotkeys menu - act as shortcuts to application functions. F1 Help Menu F2 Rotates the vessel clockwise F3 Rotates the vessel counter-clockwise F4 Toggles between the default coordinate display and the extended coordinate display F5 Toggles between enlarged and standard-sized reflections F6 Toggles between the day view and night view F7 Toggles between the About System pane and the full BEV display F8 Toggles between the Product Support pane and the full BEV mode F10 Takes a snapshot of the screen and stores the image in the file desktop.bmp, at the configured location for data logging (defined by the Path parameter in the c4config.ini file, in the CyScan Dashboard installation folder). Hotkeys Tab Start Manual Data Log (available when no tracking operation is in progress): Starts data logging and changes the button to Stop Manual Data Log. Ctrl + Zoom-In Ctrl - Zoom-Out Esc When in operation confirmation mode, cancels the current operation request; in all other modes, brings back the full BEV screen Return When in operation confirmation mode, confirm the current operation request l 16 Screen Layout (Continued) Location-Sensitive Shortcuts Certain areas of the Dashboard screen form 'location-sensitive' shortcuts within the application. To perform a function, locate the area of screen at which the shortcut is available, then click on that area. On a mouse-keyboard version, when the mouse is moved over a location sensitive area, a hand cursor will normally be shown. This indicates that clicking on it will perform a shortcut function. Activating a shortcut causes the appropriate Menu Pane to be displayed at the foot of the screen. Subsequently clicking on the same shortcut (or clicking on the Main Pane outside the BEV) will remove the Menu Pane and result in a full-size BEV. Positions of the Location-Sensitive Shortcuts on the BEV l 17 Screen Layout (Continued) Menu Pane The Menu Pane, located across the bottom of the CyScan Dashboard Screen, is not always visible. It appears when one of the Tracking, Tilt or More>> buttons at the foot of the Side Bar are pressed, or when one of the Location-Sensitive Shortcuts are followed. This causes the Bird's Eye View (BEV) to contract towards the top of the screen. Clicking the same button or shortcut for a second time causes the Menu Pane to disappear and the BEV to be restored to full size. Tracking Tilt The Menu Pane is used to display a wide variety of information and controls, often accessed by further tabs and buttons that become available once the Menu Pane is in place. The following chart shows the structure of the Menu Pane: Alarms Align Heading Blanking Zones Date & Time Screen Layout Vessel Orient. DP Feed Rotor Speed Display View can also be accessed via a Location-Sensitive Shortcut only available in Service Access mode Enable Service Access More >> Comms Setting Screen Mode Vessel Parameters Sensor Settings Power & Inhibit Product Support About System Enable Service Access Software Upgrade Buttons Tabs Buttons Tabs l 18 Tracking Information Quality The CyScan Sensor rotates anti-clockwise. On each rotation, the sensor emits a beam of infrared laser light and analyses the position of any reflections that it receives. After several rotations, the sensor is able to compare the reflections received on the last rotation with those received during previous rotations. This enables CyScan to recognise the reflections from the intended targets and to ignore any unwanted reflections. Before tracking has been selected, the Data Quality and Coordinates area in the upper left corner of the screen are grey. After tracking is started, the coordinates are initially displayed in red or amber and the quality bar is partially filled with the same colour. After a few seconds, as the scanner gathers more information, the colour changes from amber to green and more - or all - of the Quality bar is filled. This indicates that the vessel’s position can now be calculated accurately and that the system can reliably track the targets. l 19 Display Views To provide maximum visibility during daytime operation and minimal glare during night shifts, CyScan Dashboard offers two display modes: Day View and Night View. In either mode the brightness can be further adjusted by the Console Brightness control. To change the day/night view and adjust brightness: 1. Click on More >> Display View or use the keyboard shortcut F6 or the Day/Night Mode button in the CyScan Hotkeys panel. 2. Click on the Day View or Night View symbol. 3. Click on the left side of the Console Brightness control to dim the screen and on the right to make it brighter. Day View Night View l 20 Vessel Orientation CyScan Dashboard supports four different layouts of the Bird’s Eye View so that the operator can choose the one which best represents his surroundings. For instance, if the Dashboard screen is facing aft and the operator is therefore facing forward when using it, he would want the bow of the vessel in the BEV to point upwards, so that a target on the starboard side of the vessel is shown on the right-hand side of the BEV. There are two ways of setting the Vessel Orientation; one just for the current Dashboard session and the other which will still apply after the Dashboard has been closed and re-opened. To set Default Vessel Orientation: 1. Enter Service Access Mode (see Entering Service Access Mode on page 49). 2. Navigate to More >> Page 2 >> Vessel Parameters. 3. Select required Display Bow Orientation. 4. Click on the Apply button to confirm. To set Vessel Orientation for the Current Session: 1. Click on More >> Vessel Orient. 2. Click on the vessel outline that points in the required direction. l 21 Tracking Basics This section contains the following pages: Zones (page 23) • Blanking with Reflections (page 25) • Working • Scanner Tilt Controls (page 27) l 22 Blanking Zones The Blanking Zone is used to mask the segment of the scan rotation that is obscured by the vessel’s superstructure. While the scanner passes through the blanking zone, the laser is switched off to prevent any unwanted reflections from interfering with the target data. N.B. Even if the sensor has a clear 360° view, there must be a blanking zone of at least 23°. Generally, once the blanking zone has been set, it will not need to be changed. However, there may be occasions when it is necessary to adjust the blanking zone, for example if the target is on the opposite side of the vessel to normal. Changing the blanking zone whilst tracking will interrupt the data sent to the DP system. If the blanking zone is adjusted during multi-target tracking, it reverts to its previous setting when the tracking ends. However, if the blanking zone is adjusted during singletarget tracking or when not tracking, a new baseline setting is formed. Setting the Blanking Zone Selecting a Preset Blanking Zone There are two ways to set a blanking zone: The orientation of the available preset blanking zones automatically match the Vessel Orientation settings (Top, Right, Bottom or Left) accessed via More >> Vessel Orient. a Preset Blanking Zone (see below). • Selecting • Manually Defining a Blanking Zone (see page 24). To select a preset blanking zone 1. Click on More >> Blanking Zones. The Preset Blanking Zones pane is opened (see below). 2. Click on the blanking zone shape that best suits the current CyScan installation and its field of view. 3. Click on the Apply button to confirm the changes. l 23 Blanking Zones (Continued) Manually Defining a Blanking Zone Instead of using a preset shape for the blanking zone, the user can define it manually. This allows greater flexibility and precision, as the start and end of the zone can be set to any positions around the circle to the nearest degree, subject to the minimum and maximum sizes of the zone. To Define a Blanking Zone 1. Click one of the blanking zone handles and, holding down the left mouse button, drag to the desired position. Alternatively - on a touchscreen - touch and drag. As the handle is moved, its current position (in degrees clockwise from the vessel bow) is displayed in blue numerals outside the perimeter of the circle. 2. If required, drag the second zone handle in the same way. 3. The Apply-Cancel buttons will have popped up after step 1. Click on the Apply button to set the blanking zone, or on Cancel to restore the blanking zone to its previous state. The blanking zone must cover at least 23° and no more than 337°. l 24 Working with Reflections Basic Refections Data Reflections data is displayed on two panes accessed via the Tracking Button. The Reflections pane contains a list of reflections that are visible to the scanner, and the Range, Bearing and Brightness level of each: Filtering Reflections The Filter Reflections function on the Reflections pane allows the user to set minimum range and brightness thresholds. Any reflection at a shorter range or lower brightness level than the corresponding threshold is classified as a 'Reject' in the Type column of the Reflections list and is represented as a red square on the BEV. This mechanism is useful when unwanted reflections cannot be eliminated by means of the blanking zone function alone. It can be used at any time, even during tracking. a. Filtering by Range Allows the user to reject reflections that are closer than the threshold range. For example, setting the range threshold to 35m will cause any reflections from less than 35m away to be rejected. The range threshold can be adjusted between 10 and 70 metres by clicking on the end of the filter bar marked '+' or '-' as required. The user is able to filter out unwanted reflections (see below), and can choose whether to include rejected reflections in the list by means of a toggle button. Include rejected reflections: Exclude rejected reflections: b. Filtering by Reflection Brightness Allows the user to reject reflections that are below the threshold brightness level. For example, if you set the brightness threshold to 20%, any reflections that have a brightness of 19% or less will be rejected. The brightness threshold can be adjusted between 0% and 60% (reflection brightness is measured as a percentage of the brightness of the light emitted by the laser). The Brightness bar on the BEV indicates the selected brightness threshold by means of a vertical dotted line. Whilst tracking is in progress, the brightness of the primary (or only) reflection is shown by the extent of the deep yellow area, whilst the area to the left of the threshold is coloured a lighter yellow. N.B. This assumes that the primary (or only) reflection being tracked is brighter than the threshold level. The Figure to the right shows the Brightness Bar when a threshold of 20% has been applied. Range and Brightness Filter Bars The Brightness Bar indicates that any reflections below 20% brightness will be filtered out/ rejected. l 25 Working with Reflections (continued) Extended Reflection Data The Reflection Pulses pane contains details about the number of pulses that make up each reflection, and their angle of incidence. Rev # - The total number of revolutions made by the scanner rotor since CyScan was last powered up or resumed. Power - The relative output power of the laser. CyScan automatically adjusts the output power of the laser to receive an adequate reflection from the brightest target without saturating the scanner. The maximum value is 100%. Marker - The Marker displays the orientation of the scanner in relation to the vessel: 0° indicates that the scanner has been mounted with its information display facing the stern. 180° indicates that the scanner has been mounted with its information display facing the bow. Reflections - The number of detected reflections. Internal - The temperature inside the scanner unit (see Low Temperature Operation on page 63). Rejects - The number of manually rejected reflections. (See page 30). Pulses - The total number of pulses received during the last revolution of the scanner rotor. Pulse - This column displays the number of laser pulses that have been received back from each target in the following format: USING/BAD/TOTAL/REJECTED For example, if the pulses column was displaying 9/1/11/1, it would indicate that CyScan was using 9 laser pulses for the position calculation, and had discarded 1 bad pulse and rejected 1 pulse out of a total of 11. In general, the larger the target the more pulses that will be returned. This value will increase as the distance to the target reduces. Width - The Width column shows the horizontal width of each target, measured in degrees. Lower, Middle and Upper - These columns indicate whether the scanner is pointing too low or too high in relation to the detected reflections. This can occur when the CyScan vessel is working close to a rig and the targets are mounted high above the scanner (see Manually Tilting the Scanner on page 28). High readings in either the lower or upper channels can also be caused by unwanted reflections and do not necessarily indicate that the scanner is pointing too low or too high in relation to the intended target l 26 Scanner Tilt Controls The scanner tilt mechanism automatically compensates for the pitch and roll of the vessel caused by wave motion. Motion sensors and a tilting optics mechanism ensure that the scanning optics remain at the correct level to see the target. Scanner Tilt Modes The scanner can be operated in one of three tilt modes: - The scanner tilt automatically adjusts to compensate for draught changes as • Auto the vessel loads or unloads, and for gradual tidal movement. Also effective when the elevation angle of targets increases as the vessel approaches a platform. - This mode is used to manually tilt the optics to reach the target. For • Manual example, when station-keeping close to a platform where the targets are mounted high up and the CyScan optics must be tilted up at them. (See Manually Tilting the Scanner on page 28). - (service access required) - The CyScan should not be operational in this mode. •The Fixed current tilt mode and leveller angle (if non-zero) are displayed in the ‘Tilt Mode:’ section of the Side Bar. To change the scanner tilt mode and leveller angle 1. Click on the Tilt button in the Side Bar. 2. Select the required mode and click on the Apply button to confirm. 3. Click on the +/- buttons to adjust the angle. The adjacent list of estimated elevation angles for visible targets helps you to arrive at the best leveller angle. 4. Click on the Apply button to confirm your changes. Sidebar Tilt Mode section Tilt Mode Selection l 27 Scanner Tilt Controls (Continued) Manually Tilting the Scanner The Manual mode is used to tilt the scanner optics to a user-defined angle so that the centre of the fanned beam is pointing at the target. This may be necessary when the CyScan Vessel is close to a platform and the targets are positioned above the sensor. Upper Channel Middle Channel Lower Channel Beam Spread Scanner tilted up and pointing at a target mounted higher than the sensor. Spirit Level The CyScan optical receiver is divided into three vertical channels: Lower, Middle and Upper. The proportion of beam signal being received in each channel is used to determine the correct angle to set the optics. If one of the reflections in the list is selected, its elevation relative to the horizontal is shown by the position of the yellow target symbol on the right-hand side of the Leveller Graphic. The blue line represents the laser beam, and this moves as the +/- buttons are clicked. When the laser line points to the centre of the target symbol, this indicates that the leveller angle is ideal for the selected target The Spirit Level control, on the left hand side of the Tilt pane, displays the roll and pitch of the vessel as measured by the Vertical Reference Unit within CyScan. The graphical display represents the roll and pitch angles in the same manner as a bull’s eye spirit level. The current values are displayed in text at the bottom of the control. A ship outline is shown in the background to indicate orientation relative to the vessel. l 28 Single and Multi-Target Tracking This section explains the different types of target tracking that can be performed using the CyScan Dashboard, and how to configure them. It does not provide advice on how to set up a tracking operation for a specific DP system or application. The information contained in this section is for general guidance only. This section does not provide an exhaustive explanation of target tracking using CyScan, nor does it form the basis of a contract. Implementation of the material covered in this section will vary according to the type of DP system used in conjunction with the CyScan system. The use of, or reliance on, anything in this section is therefore entirely at the user’s own risk and should only be undertaken after assessment of its accuracy, completeness and suitability for the proposed use.

Click on the Tracking button. 2. Select one of the options. Single-Target Mode 3. Click on the Apply button to confirm. During Single-Target Tracking, CyScan uses a single flat, cylinder, prism or prism cluster target. Single-Target Tracking is quick and easy to use, but has the following limitations: stability is affected if the target reflection is temporarily lost, • Tracking as there is no redundancy. the true target reflection is obscured by vessel operations, • Ifthere is a possibility that the sensor track could jump to another reflection. • Relative vessel heading cannot be calculated. Multi-Target Mode In Multi-Target Mode, CyScan uses between two and five targets. Guidance Navigation recommends using a minimum of three targets. Multi-Target Mode has the following advantages compared to Single-Target Mode: tracking stability. • Improved immunity to false reflections. • Increased allows tracking to continue even if a target is temporarily lost. • Redundancy • The vessel’s heading in relation to the Multi-Target Group can be calculated. To Start Tracking In Single-Target Mode 1. Click on the required target reflection on the Bird’s Eye View. It changes to the selected state (with the number “1” superimposed) and the message “Ready To Start Tracking?” appears in the Coordinate Data area of the Side Panel. 2. Click on the Apply button to confirm and begin tracking. The current tracking mode is displayed on the Side Bar: l 30 Introduction to Single and Multi-Target Tracking (Continued) In Multi-Target Mode To Stop Tracking 1. Select a minimum of two and a maximum of five target reflections (see Selecting Targets for Multi-Target Groups on page 34). An ordinal number will be superimposed on each as they are clicked. Whilst tracking is in progress, a Stop button is embedded in the Tracking button on the Side Bar. 2. Click on the Apply button to confirm and begin tracking. 2. Click on the Apply button to confirm. 1. Click on the Stop button. N.B. Once a target has been selected, it can be deselected by clicking on it a second time. Deselecting a target may lead to the automatic re-ordering of other selected targets. l 31 Positional Display Modes The relative positions of the CyScan vessel and single or multiple targets can be expressed either as Range and Bearing values, or as 'x' and 'y' positions on a rectangular coordinate frame. Coordinate axes are only displayed if the DP feed format is set to either NMEA0183P or NMEA0183R. CyScan can also display Range and Bearing data when using these formats, if required. DP Mode NMEA0183P (Primary) NMEA0183R (Raw) Tracking Type Single-Target Multi-Target Single-Target Multi-Target All other DP modes display Range and Bearing data only. Coordinate Axes Bow and Starboard Axes Range & Bearing Range and Bearing mode displays the distance and the bearing of the primary (or only) target from the sensor. The radial markers around the outside of the BEV are zeroed in line with the vessel bow and a magenta tag marks the bearing which is the angle of the target clockwise from the bow. In the case of multi-target tracking, there is also a heading axis. This always passes through the primary target and by default it points through the secondary target, although it can be realigned if required (see Aligning a Multi-Target Group to a Given Vessel Heading on page 43). A purple tag represents the heading, which is the angle of the vessel bow clockwise from the heading axis. Bow and Starboard Axes A and B Axes When using a DP message format for which more than one display mode is supported, select the required mode by clicking the appropriate tab above the Data Quality area: l 32 Positional Display Modes (Continued) Bow and Starboard Axes This mode is available for single-target tracking, and for multi-target tracking where the DP feed messages are sent in NMEA0183P (primary) format. In this mode, the position of the sensor vessel is expressed in metres from the target along Bow (B) and Starboard (S) axes which have their origin at the primary (or only) target. The B and S coordinate axes are always parallel with the vessel's own axes. For multi-target tracking, the vessel’s relative heading is based upon a third axis passing through the primary target. By default, the heading axis is drawn between targets 1 and 2 but can be realigned if required. The radial markers around the outside of the BEV are zeroed in the same direction as the heading axis. The purple heading tag is aligned with the vessel bow, at the point on the scale that shows the angle of the bow clockwise from the heading axis. Bow and Starboard Axes A and B Axes (A Pos and B Pos) This mode is only available for multi-target tracking where the DP feed messages are sent in NMEA0183R (raw) format. In this mode, the position of the sensor vessel is expressed in metres from the target along A and B axes which have their origin at the primary target. The axes are initially aligned with the multi-target group, with the A axis passing through the secondary target. The vessel's relative heading is measured clockwise from the A axis. If required, the axes can be manually realigned to correspond with the DP system or another sensor's coordinate axes. The radial markers around the outside of the BEV are zeroed in the same direction as the A axis, which acts as the heading axis. The purple heading tag is aligned with the vessel bow, at the point on the scale that shows the angle of the bow clockwise from the A axis. A and B Axes l 33 Selecting Targets for Multi-Target Groups The terminology in this section relates to a DP Message Format of NMEA 0183R (Raw), i.e. A and B coordinate axes instead of Bow and Starboard. Correct Asymmetrical Target Spacing Selecting Reflections Target 1 When you select a reflection as a target, make sure that it corresponds to the actual target that you wish to track against. You can select up to 5 reflections to form a multi-target group. The first reflection that you select (target 1) becomes the primary target, which forms the origin of the A and B coordinate axes. The second reflection that you select (target 2) sets the default orientation of the A and B coordinate axes. If there are more than 2 reflections, select the reflection furthest away from target 1. (See Target Selection Order on page 35). Target 2 Target 3 A further 3 reflections (targets 3, 4 and 5) can be added to give redundancy to the group if targets 1 or 2 are temporarily lost or obscured. If more targets are mounted on the rig, then the superfluous ones should be physically removed and not just omitted from the multi-target group. Vessel CyScan tracks targets more accurately when multiple targets are spaced asymmetrically (see right). If the targets are not spaced asymmetrically, it is better to operate with fewer (i.e. 2) targets. Incorrect Symmetrical Target Spacing Target 1 Target Reflective Surface Key Target 3 Target 2 Vessel l 34 Selecting Targets for Multi-Target Groups (Continued) Target Selection Order e Any additional targets (targets 3-5) should be spaced asymmetrically between targets 1 and 2. w q The first target selected (target 1) becomes the origin of the coordinate axes. The second target selected (target 2) sets the default direction of the A axis. Axis B is always 90° clockwise to Axis A. Axis A runs from target 1 to target 2. l 35 Selecting Targets for Multi-Target Groups (Continued) Target Selection Order and Coordinate Axes Direction The A and B coordinate axes point in different directions according to the order in which targets 1 and 2 are selected. B By default, axis A runs from target 1 to target 2, and axis B is always drawn 90° clockwise from axis A. A Target 1 A Target 2 Target 1 Target 2 B Vessel Vessel Target 1 on Right Target 1 on Left A runs from left to right. • Axis Axis • B points towards the CyScan vessel. The left-most reflection is selected as target 1 and the right-most reflection as target 2. A runs from right to left. • Axis Axis • B points away from the CyScan vessel. Target The right-most reflection is selected as target 1 and the left-most reflection as target 2. Axis A runs from left to right on the display. Axis A runs from right to left on the display. Axis B is drawn 90° clockwise from axis A, and points towards the CyScan vessel on the display. Axis B is drawn 90° clockwise from axis A, and points away from the CyScan vessel on the display. Reflective Surface Key l 36 Axis Orientation and Vessel Heading Target Orientation in Respect to Axis A The orientation of the reflective surface of the targets is measured clockwise from the origin of the A axis to the perpendicular of a line passing through targets 1 and 2. The default orientation value depends on the relative positions of the targets: 1 is on the left when viewed from the CyScan vessel, • Ifthetarget default target orientation value is 90°. 1 is on the right when viewed from the CyScan vessel, • Ifthetarget default target orientation value is 270°. B 270° A Target 1 A Target 2 Target 2 Target 1 90° B Vessel Target 1 on Left Default target orientation in respect to axis A = 90°. Vessel Target Target 1 on Right Default target orientation in respect to axis A =270°. Reflective Surface Key l 37 Axis Orientation and Vessel Heading (Continued) Vessel Heading Vessel Heading is measured clockwise from the origin of the A axis to the CyScan vessel’s centre-line. The vessel’s relative heading value depends on the orientation of the coordinate axes. Changing the orientation of the A axis also changes the vessel’s relative heading. In the examples below, the vessel’s heading relative to the targets remains constant. However, the system measures different heading values according to the different orientation of the A and B coordinate axes. B (The reported ‘A Pos’ and ‘B Pos’ values will also change, as the coordinate axes from which they are measured have moved.) A Target 1 90° B Target 2 T2 Target 2 T1 A Target 1 270° Vessel Vessel Target Target 1 on Left Target 1 on Right Vessel heading 90°. Vessel heading 270°. Reflective Surface Key l 38 Rotational Offsets Some DP systems and applications may require the A and B coordinate axes to be rotated to match a different heading. For example, to line-up with the DP System’s own coordinate axes, the axes of another sensor, the vessel’s gyrocompass, or any other heading value. Target 1 (Origin) A Target 2 When the axis orientation is adjusted manually, both the A and B axes are rotated about their origin in the centre of target 1. Vessel heading is measured in a clockwise direction from the A axis, so changing the orientation of the coordinate axes also changes the vessel’s relative heading value. A B The orientation of the A and B coordinate axes can be adjusted by aligning the multi-target group to a given vessel heading. (See Aligning a Multi-Target Group to a Given Vessel Heading on page 43). B Vessel 90 Target Reflective Surface Key l 39 Rotational Offsets (Continued) Axis Orientation and Vessel Heading Examples In the following examples, the CyScan vessel’s relative heading to the multi-target group remains constant, and the coordinate axes are rotated clockwise about their origin (target 1). (See Aligning a Multi-Target Group to a Given Vessel Heading on page 43). The orientation of the targets with respect to the A axis is measured clockwise from the origin of the A axis to the perpendicular of a line passing through targets 1 and 2. Vessel Heading is measured clockwise from the A axis to the vessel’s centre-line. Target 1 (Origin) A B Target 2 A Target 1 (Origin) 0° 90° A B 0° 270° Vessel Default position (Target 1 on Left) Offset = 0° • Rotational Orientation with respect to axis A = 90° • Target • Vessel Heading = 0° (parallel with A axis). Target 2 Target Reflective Surface 90° Vessel Coordinate axes rotated 90° clockwise from default position. Offset = 90° • Rotational Orientation with respect to axis A = 0° • Target • Vessel Heading = 270° Key l 40 Rotational Offsets (Continued) Axis Orientation and Vessel Heading Examples (Continued) B A 270° A A Target 1 (Origin) 180° 270° Target 2 180° B Target 1 (Origin) 180° Target 2 90° Vessel Vessel Target Coordinate axes rotated 180° clockwise from default position. Offset = 180° • Rotational Orientation with respect to axis A = 270° • Target • Vessel Heading = 180° (parallel to A axis) Coordinate axes rotated 270° clockwise from default position. Reflective Surface Offset = 270° • Rotational Orientation with respect to axis A = 180° • Target • Vessel Heading = 90° Key l 41 Rotational Offsets (Continued) Axis Orientation and A Pos and B Pos Coordinates Changes to the orientation of the A and B axes affect the A Pos and B Pos coordinates of the targets and the CyScan Sensor. In the following examples, the vessel’s relative position to the multi-target group remains constant, but the reported ‘A Pos’ and ‘B Pos’ values change as the coordinate axes are rotated: 86 -50 ATarget 2 Target 1 .6 Target 2 Target 1 90° 60° 100 B B 13 Vessel 6.6 CyScan Sensor 100 Target/Sensor A A Pos Target/Sensor 0 0 Target 2 100 0 CyScan Sensor 100 100 Target Orientation with respect to Axis A = 90° (default 0° offset) .6 Vessel B Pos Target 1 36 Target B Pos Target 1 0 0 Target 2 86.6 -50 136.6 36.6 CyScan Sensor Reflective Surface A Pos CyScan Sensor Target Orientation with respect to Axis A = 60° (manual 30° offset) Key l 42 Rotational Offsets (Continued) Aligning a Multi-Target Group to a Given Vessel Heading When you manually align a multi-target group to a given heading, the A and B axes orientation and position coordinates are recalculated so that they correspond with the new vessel heading value. The heading and position coordinate data sent to the DP system will change instantly when you confirm the new alignment. You must deselect the CyScan sensor at the DP Console BEFORE commencing this operation. To Align a Multi-Target Group to a Given Heading: Whilst tracking against a multi-target group: 1. Click on More >> Align Heading. 2. Either click and drag the red compass needle to the required heading or enter the required heading value in the numerical entry box. 3. Click on the Apply button to confirm. Drag the compass needle to the required heading. Click on the Apply button. l 43 Ethernet (Multi-Console) CyScan Systems This section contains the following pages: Ethernet Dashboard - Slave Mode (page 45) • CyScan • CyScan Ethernet Dashboard - Master Mode (see page 46) l 44 CyScan Ethernet Dashboard - Slave Mode The CyScan Dashboard software, when configured to run with Ethernet Multicast or UDP communications, supports one master console and multiple slave consoles running simultaneously on the same system. An Ethernet Dashboard will default to slave mode whenever it is launched. When the Dashboard is running in slave mode the controls relating to the Dashboard itself will be active, but those relating to the CyScan sensor will be disabled. Service Access is not available in slave mode. Slave consoles display the same reflections and positional data as the master, but cannot initiate or stop tracking operations. To switch a Dashboard from slave mode to master mode: 1. Click the Guidance Home. 2. Click the unlit M button on the Side Bar. To switch a Dashboard from master mode to slave mode: 1. Click the Guidance Home. 2. Click the unlit S button on the Side Bar. When a console is switched from master mode to slave mode it will still receive feedback updates but at a reduced rate (every 3-4 seconds instead of every second). These updates are sent to all consoles and include server state information. If there is already a master console on the system this will automatically switch to slave mode when another console is switched to master mode l 45 CyScan Ethernet Dashboard - Master Mode The CyScan Dashboard software, when configured to run with Ethernet Multicast or UDP communications, supports one master console and multiple slave consoles running simultaneously on the same system. All control and configuration functions are available in a master console (Service Access is required for some of these). Any changes made to the tracking or sensor-related settings at the master console will be visible on the screens of the slave consoles. On the other hand, display options such as console Brightness or Zoom level can be set differently on each individual Dashboard, whether it is a master or a slave. When the master console is used to suspend the CyScan sensor a message will appear on the screens of the slave consoles indicating that the system is suspended. In this state, clicking the RESUME button on any slave Dashboard will automatically make that Dashboard the master console. Clicking EXIT will close the Dashboard application on that individual console only. If the CyScan system has been configured for Ethernet communications, a Dashboard will default to slave mode whenever it is launched. To switch a Dashboard from slave mode to master mode: 1. Click the Guidance Home. 2. Click the unlit M button on the Side Bar. If there is already a master console on the system this will automatically switch to slave mode when the current console is switched to master mode. l 46 Support Information This section contains the following pages: Numbers and Software Versions (page 48) • Serial Service Access Mode (page 49) • Entering Feed (page 50) • DP Power Control and Range Inhibit (page 51) • Manual • Data Logging (page 52) l 47 Serial Numbers and Software Versions These numbers identify the hardware configuration and product revision and will be requested by Guidance Navigation in the event of an application service or support call to the company.

Click on the About System button. l 48 Entering Service Access Mode There are many settings within CyScan Dashboard that can seriously affect system operation if they are incorrectly adjusted. For this reason they are concealed until you enter service access mode. Indiscriminate adjustment of parameter settings can adversely affect the operation of CyScan. It is not advisable to edit the settings unless directed to do so by Guidance Navigation Limited or a qualified technician. When Temporary Service Access is enabled, the Relinquish Service Access button on the Menu Pane shows an open padlock symbol with a red-coloured keyhole. Also, buttons on the Menu bar that can only be used in Service Access mode, are now enabled and contain a small open padlock symbol. Service Access mode can be entered either by using a temporary service access code, or by using an engineer USB key. To Obtain and Use a Temporary Service Access Code 1. Click on the More >> button. 2. Click on the Enable Service Access button. This displays the Service Access pane, which contains a Service Request Code. Using an Engineer USB Key To enter Service Access mode, either start the CyScan Dashboard with the engineer USB key already plugged into an available USB port on the Dashboard computer, or connect the USB key and click on the More >> Enable Service Access button. When USB Service Access is enabled, the More>> Menu Pane contains an inactive USB Service Access button showing an open padlock symbol with a grey keyhole. The only way to remove USB Service Access is to close down CyScan Dashboard. Ensure you restart the Dashboard without the USB key in order to return to normal access mode. 3. Send the Service Request Code to Guidance Navigation Limited (customerservices@guidance.eu.com) or an authorised customer service representative. 4. A corresponding Service Access Code will be supplied to you. This code is non-transferable and will operate only with the current Dashboard system for a limited period. 5. Enter the Service Access Code into the blank field on the Service Access pane and click on the Service Access (Locked) button. The system will enter Service Access mode for a period of up to 20 minutes, after which the system automatically reverts to normal access mode. Service Access remains available for a further 11 hours 40 minutes. 6. In order to turn on Service Access mode for another 20 minute period before the 12 hour code expires, click on the Enable Service Access button. 7. If you finish using Service Access before the end of a 20 minute period, click on the Relinquish Service Access button, followed by 1) Relinquish Temporarily or 2) Relinquish Irrevocably. l 49 DP Feed The DP Feed is the data that CyScan sends to the vessel’s Dynamic Positioning system. CyScan supports several different data message formats; it is important that CyScan and the DP system are both configured to use matching formats. Setting DP Message Format When the Dashboard is operating in normal access mode with a standard sensor, the DP Message Format can only be changed to one of the three formats shown in the above illustration. In Service Access mode, several other formats may be selected and the DP Feed pane also contains controls that determine how CyScan’s DP output behaves in certain situations. 1. Click on More >> DP Feed 2. Click on the up or down arrow in order to select the required message format. 3. Click on the Apply button to confirm the change. See document 94-0363-4 CyScan (Dashboard) Installer's Guide for a description of the available DP message formats and the different modes of behaviour. l 50 Manual Power Control and Range Inhibit Manual Power Control can be used to switch off the normal automatic power control for the rotor on the CyScan Sensor and to apply and adjust a fixed constant power instead. Manual Power Control is available when any of the following conditions are met: Access Mode is enabled. • Service Power Control has been enabled via a configuration setting. • Manual Dashboard has been connected to a running sensor that already has Manual • The Power Control enabled (perhaps via another Dashboard on an Ethernet system for example). To Enable Manual Power Control: 1. Ensure that at least one of the above conditions are met. 2. Click on the More >> button. 3. Click on the Page 2 tab. 4. Click on the Power & Inhibit button. 5. Ensure that the Enable Power Control box is ticked. To Use Manual Power Control: 1. Adjust the power level by clicking on the left or right hand side of the control until the required value is displayed. 2. Click on the Apply button to confirm the changes. To Disable Manual Power Control: Click on the Enable Power Control tick box and on the Apply button to confirm. The tick box will clear and the Power Level control will be removed.. If Manual Power Control has been enabled by a Console using Service Access, which has subsequently been disconnected from the sensor, the sensor will continue running under manual power control. Other Consoles may connect to this sensor and adjust the power level or turn off manual power control WITHOUT Service Access. Service Access will then be required to turn manual power control on again Range Inhibit The CyScan sensor will ignore all reflections below a configured range threshold. This avoids using processing capacity on very short-range reflections that are not of interest. Note that this function operates at an earlier stage of processing than does the Filter Reflections function (see Working with Reflections on page 25). Range Inhibit is only available in Service Access Mode (see Entering Service Access Mode on page 49). To Set the Range Inhibit Threshold: 1. Click on the left or right hand side of the control until the required range is displayed. 2. Click on the Apply button to confirm the changes. l 51 Data Logging During tracking, the system automatically generates a set of operation logs that can be analysed by a service engineer to diagnose any system faults. Logging can also be started manually, when the system is not tracking (see below). Logs are written to compressed folders that each contain approximately one hour’s data. The folders are named according to the date and time period that they cover, and the type of navigation that was being carried out. For example, logs recorded between 1.30pm and 2pm on the 4th May 2014 during multi-target tracking would be stored in a folder named: Taking Screenshots The Screenshot option records every detail of the current screen and stores it as a bitmap image. Screenshots can be analysed by a service engineer or e-mailed to Guidance Navigation Limited in the same way as log files. The screenshot is stored in the file desktop.bmp, in the same directory as the log files (C:\Logs by default). If a desktop.bmp file already exists, it is overwritten. 04d05m2014y 13h30m00s to 04d05m2014y 14h00m00s multi target.zip To take a screen shot: Logs are stored in the C:\Logs folder by default; a different location can be specified by closing the Dashboard and editing the Path parameter within the c4config.ini file in the Dashboard installation folder. Either Logs can be e-mailed to Guidance Navigation Limited (customerservices@guidance. eu.com) or your DP Supplier in the event of a problem. 1. Click on the Hotkeys tab. 2. Click on Grab Screenshot. Or Press the F10 key. On a CyScan system with multiple Dashboards, data logs are written by whichever Dashboard is the master. If another Dashbard then takes over as master, the location of the logs from that time forward will also change. Starting and Stopping Manual Logging To start logging when CyScan is not navigating: Either 1. Click on the Hotkeys tab. 2. Click on Start Manual Data Log. Or Press the Alt+L keys. To stop manual logging: Either The Grab Screenshot and Start Manual Data Log buttons 1. Click on the Hotkeys tab. 2. Click on Stop Manual Data Log.

These alarms only apply to the embedded navigator and the interaction between the sensor unit and the Dashboard user-interface. Fatal Alarms—Codes 2xxx Signifies a fatal event such as malfunctioning software; the system might be able to recover from this but a power cycle is always recommended (both sensor unit and Console computer). Errors—Codes 3xxx Signifies an unexpected event such as a missing parameter file or a lack of response from a particular sub-system; these errors normally clear themselves after a while. If these errors occur repeatedly in quick succession especially after restarting the system, then a serious hardware problem might have occurred. Warnings—Codes 4xxx Signifies a possible error source; it will be followed by a relevant error message if the system deteriorates, otherwise this will clear itself in due course. In general most warnings if they are infrequent can be ignored. Information—Codes 5xxx Signifies purely an event, user initiated or automatic, for audit purposes. Proxy Alarms—Codes 6xxx - 6499 Controller Alarms—Codes 65xx - 6999 Rotor Alarms—Codes 7xxx - 7999 Proxy alarms, controller alarms and rotor alarms all signify events that are associated with the sensor rotor, tilt mechanism or controller hardware. These codes can provide diagnostic information about issues with this hardware. l 55 Cleaning the Sensor and Targets To maintain the CyScan Sensor in good working order it is important that its optical elements are kept free of contamination. To clean the optical window Use a lint-free cloth with IPA spray to carefully wipe the optical window. To clean the targets In dirty environments the reflective faces of the targets should be cleaned regularly for best viewing. Under icy or frosty conditions, the targets should be cleared of any condensation or ice. l 56 CyScan Fuse Information The CyScan system contains two replaceable fuses, one for the Live and the other for the Neutral. These are located on the connector board as shown below. Connector Board Fuse Please refer to the Installer’s Guide for details on how to access the connector board. Live To remove a fuse from its housing, fit a flat-head screwdriver into the slot in the insert - then push it in and turn it anti-clockwise until the insert releases and can be pulled out. Reverse the above procedure to replace the fuse. Both fuses have the same specification. Neutral Ensure the replacement fuse has the same specification as the original fuse.

Cylindrical targets can be used up to approximately 300 metres. They can be hung over the side of the structure/vessel and secured at either end. Prism cluster with 8 x 6cm elements for extended range operations. Variable configurations allow for optimisation of the visible reflection, visible reflection level or reflected power. 2 metre tall flat targets can typically be seen at up to 400 metres in ideal conditions. Shorter 1 metre tall flat targets are visible at up to 250 metres when viewed straight on. Part number: 20-0078-0-B (1.9m cylindrical reflector) Part number: 20-0075-1-A Part number: 20-0031-0 (2m x 350mm flat reflector including stainless steel bands) l 60 TECHNICAL NOTE 2 Targets-Installation and Position (Continued) Target Installation Key to the operation of the CyScan system is the correct installation of targets. Please follow the guidelines given below when installing targets on the structure/vessel. Once the targets are installed, their relative positions can be automatically surveyed by the system.

Ideally they should be placed • Targets 10m or more apart. û 45 o 45 o VIE AN WAB GL LE E Targets are asymmetrically spaced, thus making it easier for the CyScan system to assess which reflection corresponds to a particular target. û Targets are too close together and have even spacings. This makes it more difficult for the CyScan system to differentiate them. l 61 TECHNICAL NOTE 3 Vertical Beam Divergence CyScan has an optimised optical system to ensure that bearing precision and target lock are maintained even in high sea states and over the full range of the sensor. The optics produce a vertically divergent beam (12°) with a very narrow profile. As the distance from the target increases the beam becomes deeper as shown in the diagram.

It is recognised that industrial marine operations may subject these components to harsh environments, including low temperature. CyScan is designed to operate within the temperature range – 25 to 70°C. The hardware complies with the requirements of IEC 60068-2-1 and is able to operate for prolonged periods at temperatures down to – 25°C provided that certain operating conditions are maintained. If there is a requirement for CyScan to operate at temperatures below -25°C, contact Guidance Navigation. Operating Conditions The following recommendations are made for low temperature use: it is necessary for the system to be switched on after a prolonged period at • Iftemperatures below 5°C (and down to – 25°C) the sensor will warm itself, but will require some time to reach optimum operating condition.

Click on More >> Date & Time or else click on the digital clock near the bottom left of the Main Screen. This opens the Date & Time pane: The system’s current date and time is displayed as a static value; the Refresh button can be used to update this. 2. To set a new date and time simply amend the contents of the text box and click Set New. 3. Click on the Apply button to confirm (the new setting will not take effect until you do this). l 65 Using the On Screen Keyboard In order to accommodate systems without keyboards, CyScan Dashboard provides an onscreen Keyboard (OSK) option. This enables text to be input using only a mouse pointer or touch screen. In the case of a numerical field, the OSK is restricted to the appropriate keys: To enable the on-screen keyboard If, during installation, you indicated that the Dashboard would be used with a touch screen, the OSK will already be enabled. Otherwise, edit the c4config.ini file in the CyScan Dashboard installation folder (typically C:\CyScan Dashboard), find the OSK parameter and set as follows: OSK=1 To use the on-screen keyboard Simply click on any text entry field and the OSK will pop-up ready for use: When you have finished using the OSK, click on a different part of the screen and the OSK will disappear. Click on the necessary keys on the on-screen keyboard using your mouse or by tapping the touch screen. l 66 Working with Alarms During operation, the CyScan system produces an audit trail of event messages. These range in increasing order of severity from: Information, Warning, and Error to Fatal. As these alarms are raised, the Dashboard lists them within the Alarms pane. Click on any alarm to display details about it in the right-hand section of the Alarm pane: Filtering Alarms A filter is available to suppress the display of particular alarm types. By default, the filter is activated and causes information messages to be hidden. Click on the Alarm Filter button to toggle between activated and de-activated . Click on the Filter Selection button to choose which types of alarm are to be filtered out: The severity and current state of an alarm are reflected in its colour and shape: symbols • Information—grey symbols • Warning—orange symbols • Error—red • Fatal—red symbols Alarm types that are ticked are always displayed in the alarms list, un-ticked types are hidden when the filter is activated. The arrowhead symbol indicates that an alarm condition is persisting; an alarm in this state will show a Start time but not a Stop time. The square symbol means that the alarm condition no longer exists, therefore the alarm will show both Start and Stop times. The pause symbol indicates an instantaneous alarm. In this case, the Start and Stop times are identical. When an Error or Fatal alarm is raised, the Alarms pane is opened automatically and its Side Bar button is shaded red as in the example above. If the pane is closed and reopened, the Side Bar button returns to its normal light grey shading. l 67 Working with Alarms (Continued) Using the Historic Alarm List The Alarms tab has two alarms lists: Current Alarms List displays new alarms (since the last start of the Dashboard • The software). Historic Alarms List is used to store alarms that have been cleared from the • The current list. Current alarms are automatically transferred when the Dashboard is closed. Items in the Current List cannot be deleted, they may only be moved to the Historic List. Only items in the Historic List can be permanently deleted. To accept alarms in the current list 1. Click on More >> Alarms and ensure that the Current Alarms tab is in focus. 2.
