Note! Insert or remove C-MAP cartridges ONLY through CHART menu or when unit is off. All electronic navigation equipment is subject to external factors beyond the control of the manufacturer. Therefore such equipment must be regarded as an aid to navigation. The prudent navigator will, for that reason, never rely on a single source for position fixing and navigation.

CP42/50/52 Introduction and safety summary Chapter 1

1.1 Introduction and system familiarization

Congratulations on your purchase of SIMRAD CP42/50/52 MKII DGPS Chartplotter - a combination of the latest GPS receiver technology and

built-in differential receiver for accurate positioning and prepared for SDGPS, plus: detailed cartography; all in a unique slim-line design with a 10” ATFT (CP42), 14” TFT (CP50), or 15” TFT (CP52) large LCD display in color.

The CP42/50/52 MKII chart system includes a built-in world chart for rough planning and overview. The choice of chart system best suitable for the CP42/50/52 MKII was carefully singled out to be the C-MAP NT+ mini cards. The optional C-MAP cards are available world-wide at your local Simrad dealer.

The Global Positioning System is at this time and age the most common system used for navigation and positioning all over the world. Not only for maritime use, but also for land-based applications and aviation. The satellite-based system has been developed and is operated by the US Department of Defense in order to provide an accurate and reliable service, which include a 24-hour global coverage. The GPS system consists of approx. 24 satellites which orbit around the Earth at an altitude of approx. 20,200 km. The satellites transmit perfectly synchronized data. However, depending on the position, the signals will reach the receiver at a slightly different time. By adding the measured time difference to the known position of the satellites it is possible to calculate the ship’s position to within a few meters.

DS42/50 Dual Station for the CP42/50/52 is available in 10” ATFT color, 14” TFT color and 15” TFT color.

How to use this manual? The manual is written for the products: CP42, CP50 and CP52, which all share the same type of software. From hereon, these models are referred to as: CPXX. It is a good idea if you make yourself familiar with the key functions, menu structure and rotation of pages (screens) described in chapter 2 before you start out, and then proceed with section 2.7 Initial start-up. For quick location of a certain term, please check the ”Glossary of terms” and the ”Index” at the back of the manual.

Indicates that you should press the keys [1] and [3] to obtain what is written in italic next to the keys.

1.2 Safety summar y

Precaution The operating unit should not be exposed to direct sunlight, as

“boiling” the display may cause too high temperatures internally and subsequently damage parts of the unit beyond repair.

Quality service personnel The CPXX is sealed and does not contain any user serviceable parts. Opening of the unit will void its warranty. Touching electrical parts inside may cause bodily harm or death. If the unit is not working properly, please check section 10.11 Troubleshooting. If your CPXX requires servicing or repair, call your authorized SIMRAD dealer.

Power source, fuse and power cable Check that the DC power supplied to the unit is within the range of 10 to 32 volts. Note that the appropriate fuse must be employed (F6.3A). Ensure that the power cord is firmly attached.

Grounding To reduce electrical interference and risk of electrical shock, properly ground the unit to the ship’s ground using the ground screw on the back of the unit. Good grounding should also be exercised for connected equipment.

Default settings All user implemented data in the CPXX can be erased by making a reset of the unit and thus return to factory default settings.

CP42/50/52 Fundamentals & initial start-up Chapter 2

2.1 Fundamentals of the PAGE and WINdow system

The CPXX DGPS Chartplotter has a multi-function screen data presentation system. You can choose to have a full screen, or a screen divided into e.g. a chart display and two data/chart displays, etc. The display which is currently activated is indicated by a highlighted frame around the active window. There are five screen combinations to choose from:

WINdow 0

1. Full (1/1) screen. 2. Four ¼ displays. 3. Two ½ displays.

4. & 5. Combination displays of one ½ and two ¼ displays shown together in the same screen. ) Not all displays are available in WINdows 5 and 6.

CP42/50/52 Fundamentals & initial start-up Chapter 2

As many as 4 screen combinations or full screens can be saved in 4 pages (layers).

Press the

[PAGE] key to toggle between the 4

pages, or hold the [

PAGE] key depressed for

two seconds to start a rotation of the 4 pages. Press [

PAGE]

again to return to manual

operation.

To mix and match the various chart and data displays you wish to have in the PAGE and WINdows presentation, you will first need to know what is pre-set from the factory:

PAGE

Scroll through the four pre-set pages to see if you wish to exchange any of the displays with a different one.

Example of how to edit a pre-set page:

window

We pretend that in this page, window 2 contains the navigation display (highway), window 3 a chart display in a large scale for overview, and window 5 a chart display in a smaller scale to enlarge a

certain area. You now wish to insert the Position display in window 3 instead of the chart display. This is the procedure:

WIN

Press the

[WIN]

key until the frame around window 3 is highlighted

Call up the menu bar, and…

2,1

then call up the POS menu and select “Position”

- you will now have the Position display in window 3 instead of the chart display.

Example of how to edit a full screen to four ¼ displays:

We pretend that you are looking at a full screen which you wish to divide into four ¼ displays. This is the procedure:

First call up the menu bar, and…

then call up the POS menu - see example next page.

CP42/50/52 Fundamentals & initial start-up Chapter 2

POSITION

POS

_1_ Position _2_ Dual speed _3_ Speed, course & depth, etc. …

What you do now will determine which WINdow the display you are about to select will appear in.

Press the

[WIN] keyrepeatedlyto

scroll through the window system.

WIN

Press the [WIN] key once to select WINdow 1

-which is the left top quarter of the screen.

Select the Position display

- you will now have the position display presented in window 1. The rest of the windows in this page i.e. window 2, 3 and 4 will contain the displays which were pre-set from the factory. They can all be exchanged with new displays at your choice.

) However, the same display can not appear twice on the same page, so in case you are trying to select the same display in a second window, this is what will happen:

As per above example, you have selected the Position display in window 1, but it may just happen that the Position display was pre-set to window 2 – therefore window 2 will now show the legend: “ Select display via MENU.”

You may select the same display to appear on different pages, but not on the same page.

CP42/50/52 Fundamentals & initial start-up Chapter 2

2.2 Key functions

All C-MAP feature groups i.e. Land settings, Marine settings, Naval aids settings and Paper chart settings are described in Appendix C. To obtain a “cleaner” view of the chart details, you can turn some of the settings OFF if they do not contribute to the clarity of the chart area you wish to explore. All the listed objects that can be turned on and off speaks for themselves – they are either “shown on the chart” or “not shown on the chart”.

CP42/50/52 Chart menus and INFO windows Chapter 3

All user data in the chart system are listed under ‘Chart settings’ in the display example and are described below:

Chart can be set to

NORMAL, COMPRESSED and CHART OFF:

NORMAL

- will automatically select the chart level appropriate for the selected

range/scale.

COMPRESSED

- will change the range (scale) / chart level ratio one step, which,

depending on the actual chart, will select a more detailed level.

CHART OFF - will only show all the user-made data such as waypoints, routes,

lines and tracks, etc.

Boundary lines will indicate available C-MAP chart areas.

Mixing levels – when set to ON you will no longer see any blank chart areas, as

the C-MAP library will find the missing area in a different level to cover the blank area otherwise left on the screen. However, when using this feature, chart re-draw time will be increased a little.

Marine presentation can be set to INTERNATIONAL or AMERICAN: INTERNATIONAL – will present NavAids in ‘real life’ shapes and colors for quick visual recognition (as per official INT1 standard paper chart presentation). AMERICAN – will present NavAids in simplified shapes and real colors (as generally found on NOAA paper charts).

Simplified draw mode – when set to ON the NavAids will be shown in generic symbols for minimum visual clutter on-screen.

Quick chart info – placing the chart cursor on a C-MAP object will activate a small info window with details on the object. Info window will automatically close after 10 seconds or when cursor is moved away.

Chart area can be set to

SMALL, MEDIUMorLARGE.

SMALL

– Opens a small chart area big enough to just fill the size of the screen.

When panning and scrolling, the chart will automatically be redrawn.

MEDIUM

– Opens a medium-size chart area for pan and scroll which goes beyond

the size of the screen. The chart redraw time increases equally.

LARGE

– Opens a large chart area for pan and scroll in a size which goes well

beyond the size of the screen. The chart redraw time increases equally.

– The chart will always be presented as north up.

HEAD UP – The chart will automatically turn, so your actual course (COG) is up.

If a compass is connected, the reference will automatically change to heading (compass).

NAV UP

– The chart will automatically turn, so your bearing to destination is up.

) To enable chart rotation the chart cursor must be turned off [CLR].

TRUE

motion – The ‘ship’ will move across the chart.

RELATIVE motion – (‘Chart area’ will default to MEDIUM). The ‘ship’ is locked

to the center of the screen and the chart will move.

Rotation resolution can be set to adjust the chart for each 5, 10, 15, 20 or 25° changes in present course or heading.

Depth–Level1,2and3 are identified by different colors. The number of meters in the levels can be changed. The colors are preset, see section 9.6.

Grid the LAT/LON grid can be set AUTO/ON/OFF. The color of the grid is preset in Palette setup, section 9.6.

Show range ON will add a small line to the chart display indicating that the length of the line equals a certain number of nautical miles/km.

Auto chart select When sailing with “Auto chart select” ON and cursor turned OFF, the scale will automatically change to the chart which is available. But when set to OFF, then the selected scale will remain, also when sailing “out of the chart”.

Extended level range ON will enable changing range 3-4 steps within the same chart level after having selected the range via a numeric key.

Status indicator and accuracy

Small letters (a,b,c,) indicate that SA is active, and the position accuracy is expected to be better than 100 meters in 95% of the time. Capital letters indicate that SA is OFF, and the position accuracy is then expected to be 15 meters or better in 95% of the time. dGPS indicates that differential data is received, either via built-in differential receiver or from external receiver. DGPS or SDGPS indicates that the position is corrected by the differential data. The accuracy will typically be 1-3 meters for DGPS and 2-6 meters for SDGPS.

In order to utilize the high accuracy of the GPS system, it is necessary to align the lat/long calculations to the paper charts you are using. RefertoPositionsetupdisplayonnextpage. ) When using C-MAP electronic charts, the datum will be aligned automatically.

PDOP (position dilution of precision) is equivalent to 3D positioning. The values will typically stay between 1.3 and 8. The lower the value the higher the “quality”. A poor geometry might produce a value of more than 20.

If the preset DOP limit is exceeded (indicated by * in the position display) it will cause the position updating to stop until it once again is within the limit.

The DOP limit can be changed manually, but should not be set higher than 8 (factory setup), as this may result in poor accuracy – false position.

YES

it should be safe to rely on the received differential data, because the beacon station’s performance is under observation. If

, then you have to use the received differential data with caution,

as there is no guarantee it is not faulty.

Frequency – the frequency of the beacon station can be set manually if known. However, when left in

AUTO

the navigator will always search

for the nearest station with a good signal strength.

Bit rate – indicates bits per second, and can be set manually to 25, 50, 100 or 200 bps.

Signal strength – a good signal strength is 20 and up.

Signal to noise ratio (SNR) – should be 8dB and up.

Message – type 16 message will be displayed when received from the

DGPS system. The contents of this message could be something to do with the performance of the system. Temporarily out of service, etc.

CHANNEL 1: sat.no. - indicates which satellite number and name is currently tracked/searched by channel 1, and what is the tracking state.

Corrections - indicates if corrections are being received on this channel. If YES: is the quality of the reception sufficiently high for the corrections to be usable.

NONE: no corrections are received. RECEIVED: corrections are received, but of insufficient quality. USABLE: corrections are received and of sufficient quality. USED: corrections received on this channel are used in the position

determination.

Integrity messages ok - the SDGPS system will transmit messages concerning the integrity of the GPS satellites. This line will indicate whether such messages are received and reliable.

Range used for position fix - if the receiver is tracking a particular SDGPS satellite, it “knows” the distance to that satellite. This line will indicate whether the distance is used in the position determination.

Type 0 warning received - if an SDGPS satellite is not operating according to specifications it will transmit a so-called “Type 0 warning”. In this situation, the receiver will not use any information that it might receive from that satellite. Until the SDGPS system is declared operational, the SDGPS satellites will always transmit Type 0 warnings. ) It is possible (but not recommendable) to override the Type 0 warnings - refer to last line in SDGPS setup.

DataCards and TL50 Turbo Loader are optional equipment available from you local Simrad dealer. How to perform data transfers via TL50 Turbo Loader (inclusive data from Shipmate RS2500 Trackplotter) is described in the TL50 manual.

Use the Simrad DataCard or TL50 Turbo Loader to make backup files of all the user data you have created plus the current setups in the internal memory of the unit. Do it whenever you have added important data, or when you wish to transfer routes and waypoints, etc. to another compatible unit. The storage capacity of the DataCard/TL50 disc is divided into two databanks of each 450 Kb, meaning that the entire internal memory can be stored in one databank.
