Technical Manual
STANDARD MARIS ECDIS900 INSTALLATION
The standard installation of the MARIS ECDIS900 includes two workstations connected by
LAN: the monitoring workstation and the planning workstation used as a backup.
In this chapter, learn moreabout:
•Monitoring and planning workstations
•System description
•Functional description
•Redundancy in the system
•Tests facilities
•Input/output management - Sensor Monitor application
•Failure detection
•Security
•Maintenance
•Power
MONITORING AND PLANNING WORKSTATIONS
The monitoring workstation acquires position, Gyro/Log and ARPA Targets data via serial
lines, and a second DGPS delivers position information to the planning workstation. All
serial sensor inputs are broadcast on the network and shared by the two ECDIS900
workstations.
Note: The second DGPS is optional and the same DGPS can be used on both workstations.
However, it is recommended to use two different DGPS for redundancy and safer installation.
Installation
During the ECDIS900 installation process, select the Monitoring option for the monitoring
workstation and Planning for the other ECDIS900 workstations.
However, it is possible to switch between monitoring and planning modes by right double-
clicking in the window title of the ECDIS900 and activating the menu Set as planning
station or Set as Monitoring station. Only one monitoring workstation can exist in the
ECDIS900 LAN. As soon as the planning workstation is switched to monitoring, all monitoring
functions are available on this PC.
Shared data
The charts and routes databases are installed on both workstations. Therefore, if there is a
breakdown of the monitoring workstation, the planning workstation can immediately be
used as the main ECDIS900. Then it is required to switch from planning to monitoring mode
as described above to access all route monitoring functions.

7
Planned routes
When routes have been planned on a planning workstation, they can be copied to another
ECDIS900 workstation. Right-click on the route and access the Synchronize menu. The route
will be copied to all active ECDIS900 workstations.
Alternatively, it’s possible to import routes using the following procedure:
•On the target PC, open the dialog Load/Unload objects, and from the Routes tab select
Import
•Select the folder containing the route located on the Planning station:C:\\
ECDIS_userdata\Routes
•Select Routes to be imported
•Select OK and the routes are copied on the local PC.
Another way to copy a route to all active ECDIS900 workstations is to right-click on the
route and select Synchronize.
Active route
A route can be activated only on the monitoring workstation. When the route has been
activated, it will be automatically transferred and displayed to the other ECDIS900
workstations running on the LAN.
IMPORTANT: Activating a route is only possible on the monitoringworkstation.
Charts
To synchronize ENC or ARCS chart collections, use the Copy database function available in
the chart handling dialog.
HARDWARE PLATFORMS
MARIS ECDIS900 systems come in several variants:
Stand-alone unit:
•MARIS ECDIS900 MK15 19” 4S
•MARIS ECDIS900 MK15 24” 4S
MARIS ECDIS900 MK5 and MK5A can be delivered with four different monitors:
•Hatteland 24" monitor
•Hatteland 26" monitor
•Simrad®M5024
•Simrad®M5027
For more information about hardware, see the MARIS ECDIS900 System Installation Manual.

8
User Input
GENERAL
The ECDIS900 is a window-based, human computer interface (HCI) where operator-requested
information is obtained from menus and dialog boxes on the display. The mouse is the
main operating tool for the system. A keyboard is also necessary for alphanumeric data
entering.
STORAGE MEDIAS
Hard disk
The ECDIS900 workstation is delivered with Windows 7 and necessary system drivers and
libraries alreadyinstalled.
When the ECDIS900 is installed on the computer, the necessary files are copied to the hard
disk and four folders are created:
•C:\ProgramFiles(x86)\MARIS containing:
•The application ECDIS900 and necessary libraries in the Bin folder
•The Sensor Monitor application
•Utilities
•C:\Charts containing all data related to chart collections
•C:\Ecdis_UserData containing user data like routes, tracks, object editor, tide database,
weather, logbook
•C:\Program Data\MARIS containing:
•Configuration files
•S-52 presentation library components
•Log files for the ECDIS900, including listing of chart installation and updates.
Memory stick
Memory sticks are used to:
•Install chart permits when S57 or ARCS permits are transmitted by memory stickor
received by email
•Update S57 chart database when the updates are received by memory stick oremail
•Backup and restore routes, logbooks and user data stored on the hard disk
•Boot the system when a complete restoration of the hard disk is necessary.
CD(DVD)-ROM
CD-ROM are used to install and update charts.

9
SENSORS
For a complete description of the interface between sensors and the ECDIS900, see the
Input/Output chapter.
ETHERNET: INTERNAL AND EXTERNAL DATA FLOW
Ethernet and TCP/IP protocol are the core of the system for the intercommunication
between software modules and for data exchange between the ECDIS900 planning
(backup) and monitoring workstations.
Intercommunication
LAN communication is the technology used in the system for communication between
ECDIS900 applications. For example, the ECDIS900 application launches the application
called Sensor Monitor responsible for I/O of the system. This application runs in parallel
with the ECDIS900 and manages serial and TCP/IP input/output. ECDIS900 and Sensor
Monitor use TCP/IP protocol for data and command exchanging.
Monitoring and planning workstations on the same LAN communicate using TCP/IP
protocol.

10
Notes:
•The two ECDIS900 workstations share the same sensor data information. Serial data
is analyzed and broadcasted on the LAN and therefore the other ECDIS900
workstation can use thesame sensor input data.
•Routes are usually planned on the planning workstation and then transferred
to the monitoring workstation via Ethernet.
•The monitoring workstation oversees the active route and waypoint. Information about
the active route and waypoint is sent to the planning workstation via Ethernet.
•The ship’s settings and safety parameters are synchronized on the network. The
ship’s settings and safety parameters can be adjusted on the planning workstation
and thenthe parameters will be updated on all planning workstations.
•Alarm acknowledgement is also synchronized. When an alarm is acknowledged onthe
monitoring workstation, it is also acknowledged on other planning workstations.
Chart databases on both ECDIS900 workstations can be updated in two differentways:
•The update procedure can be run twice on both workstations.
•The update procedure is run once, and the updated chart database is transferred to
the other workstation via Ethernet.

11
Technical
REDUNDANCY
Backup system
The ECDIS900 dual system installation includes an ECDIS900 monitoring workstation
working as master, and an ECDIS900 planning workstation working as a slave. If the main
ECDIS900 monitoring workstation breaks down, the planning workstation can immediately
replace the master and can be used for navigation.
Continuous monitoring
To avoid any interruptions in the ship’s position monitoring, the ECDIS900 backup is
connected to the second GPS. If the master ECDIS900 breaks down, the ship is monitored
on the backup system.
Active route
The monitoring workstation is responsible for the active route and waypoint. The active route
and waypoint information is sent continuously to the planning workstation, which displays
the same route. Any changes of active route are prohibited.
Duplicate databases
All ECDIS900 workstations should use the same chart databases. It is the user’s responsibility
to maintain the consistency of the chart collections and to transfer routes from the planning
workstation to the monitoring workstation.
Logbook
The logbook database, which contains all navigation information of the current voyage, is
stored on both workstations. If there is a breakdown, no data is lost and the second PC
continues to store navigation data to the logbook. The time interval of logbook recording
cannot be changed and is equal to 15 seconds.
Synchronization
Ship’s settings and safety parameters (safety contour and safety depth) are synchronized on
the network. On the monitoring workstation, the ship’s settings and safety parameters
can be adjusted and these parameters will regularly be updated on all planning workstations.
Alarm acknowledgement is also synchronized.

12
Setup
The logbook window gives access to the Change Settings button. Tick the Save
checkbox in the Voyage Data recorder section to make sure the logbook will be recorded
by VDR. A logbook recorded in VDR could be replayed in ECDIS900 together with otherdata.
IMPORTANT: Logbook settings are not synchronized on the LAN.
Positioning systems
Two ECDIS900 workstations are connected independently to two different GPS sensors
through the SIS4000 unit. However, they share the same data and both ship’s positions are
displayed on the chart: GPS1 data, acquired by one of the ECDIS900 workstations is sent to
the other one by Ethernet and vice versa. GPS2 data acquired by the second workstation is
sent to the first one.
When two different GPS sensors are used, you can select which GPS sensor is the master
positioning system, i.e. which position data is used for route monitoring calculations. If the
master GPS fails or sends faulty data, you can select another GPS sensor as master.
Gyro and log data
Gyro as source of heading is interfaced to both workstations.
TEST FACILITIES
Boot tests
When you power on or restart the computer, it goes through power on self-test (POST)
routine, which determines:
•The amount of real memory
•Whether the required hardware components are present.
Once the computer has run its POST routine, each adapter card with BIOS runs its own POST
routine. The computer and adapter card manufacturers determine what appears on the
screen during the POST processing.

13
Windows operating system consistency
Windows 7 does not start up or operate correctly if any hardware components do not initialize
correctly. Startup fails if any of the files required to start Windows 7 are not present in the
correct folder or if one of the files has beencorrupted.
Connection tests
When one or more input and/or output devices are connected to the computer, the
connections must be tested to ensure that everything is working correctly. ECDIS900
provides a useful tool to help perform this test.
Hyperterminal is an application built into Windows operating systems that allows testingthe
connections with input devices. If input devices are correctly connected, the Hyperterminal
displays recognizable characters. Incorrectly connected input devices will either show no
information or garbled characters.
FAILURE DETECTION
Power failure
Visual failure detection
•Check the LED on the UPS.
•When the system is powered, the LED in the front panel of the screen is
immediately switched on.
Computer hardware failure
Audible failure detection
During the boot process, an audible alarm is triggered when there are RAM or video
problems. The sound sequences differ, depending on the type ofproblem.
Visual detection
•If the hard disk cannot start during the boot process, a warning is displayed in grey ona
black background screen.
•During Windows operating system boot, the system displays the log of all events ona
blue background screen.
Communication failure
After Windows 7 has started, ECDIS900 is automatically launched, and the network initialized.
If there is an Ethernet problem, the different sockets cannot be created, and a warning is
displayed. If the connection with the sensors cannot be well established or a failure occurs,
ECDIS900 warns the navigator.

14
Software failure
Software failures are reported in two differentways:
•Exception and memory errors messages are displayed in an alarm dialog.
•The error freezes the system, for example, the mouse is still moving but menus areno
longer accessible.
SECURITY
Computers running ECDIS900 are dedicated to navigation purposes and SHOULD NOT be
used for any other tasks.
System set-up
Access to system setup and configuration functions is restricted, and the main window of
ECDIS900 is not resizable. Hiding that window is not possible and the Windows task and
caption bars are not displayed. Other applications are accessible only when operating
Application Manager in service mode.
When the computer boots, ECDIS900 is automatically launched, and Windows system
functions are not accessible when ECDIS900 is running in operational mode.
System hot keys are disabled
In operational mode, ECDIS900 restart and shutdown functions are only available through the
Application Manager. All windows system hotkeys aredisabled.
Access
The two workstations are used for navigation purpose only and no other application can
interfere with ECDIS900, except for approved applications and Application Manager. The
workstations are connected by a point-to-point Ethernet connection and are not a part of the
ship’s network. Therefore, no access from outside of the ship is possible.

Input filtering
Keyboard inputs are secured, i.e. filtering functions check that the use of letters and numbers
is correct and the values are within definedlimits.
If there is insufficient input, the system cancels the input or asks for additionaldata.
COLOR TABLES AND BLACK ADJUSTMENT
In the presentation library V4.0, three color schemes areavailable:
•Day bright
•Dusk
•Dark night.
The colors can be selected from the Chart settingdialog or by pressing F8 on the keyboard.
Backlight adjustments
The monitor backlight level is automatically adjusted to the calibrated value when a color
scheme is selected. Three levels of backlight corresponding to the three color tables have
been defined during the color calibration process.
Manual adjustment
The monitor Pot meter is disabled. To increase or decrease the backlight level from the
predefined backlight value, press the key combination “Ctrl +” or “Ctrl –“. The minimum
display brightness is maintained to keep ECDIS900 alarms visible under any conditions.
IMPORTANT: Manually changing the backlight level may alter the colors in the ECDIS900.
Color differentiation – chart1
The presentation library contains a color differentiation test diagram to check that the display
can be used to discriminate important features by color. The cell called AA5C1W00 (displayed
at the scale 1/25 000 and located at 15N, 5W) contains several colored differentiation
diagrams. To access the Chart1 cell, open Chart handling, select the Chart1 tab and
double-click on one of cells in the list. Data will load and the appropriate cell displays. Use the
scroll and zoom tools to review neighboring cells from the Chart1 collection.

TESTS
Functional testing before delivery
The different parts of the system must be tested for correct functionality. They must first
be verified as <OK> by the system itself (BIOS). Before and after burn-in, a special test
program (CheckIT) must be run, with test reports printed and saved for eachunit.
Computer
Check the BIOS self-test reports and verify there are no errors.
CD(DVD)-ROM
Verify reading. Test throughput.
Hard disk
Verify read/write performance. Test throughput.
I/O ports
Network
Ethernet 10/100 MB TP: Test connection
Ethernet 1Gb TP: Test connection
Speaker
The frequency of audible alarms is about 750 Hz and the volume is set to maximum, which
gives an audio level of 75 dB at a distance of 1 meter from the ECDIS900 workstation.
LCD monitor
The testing of the monitors must be done PRIOR TO DISMANTLING. If errors are found, the
monitor MUST NOT BE OPENED, but returned for warranty replacement.

18
Back light
Verify the intensity, both maximum and minimum, to be subjectively within normalrange.
Graphics
Verify there are no ‘hanging pixels’, cracks, stripes or other visible flaws on the units, by
connecting them to a PC running at 1280 x 1024 resolution. There should not be any visible
‘ghosting’ or blurring.
System performance
Upon power-up, automatically start the ECDIS900 software. Test it is possible to zoom and
pan maps. Using the integrated simulator (Dead Reckoning and Simulation active functions),
test that both ‘own ship’ and ‘target ships’ move on themap.
Functional tests
Indicators and alarms
•Disconnect the GPS cable. After the GPS alarm timeout, the GPS alarm is triggered.
•Start the logbook replay function: the GPS indicator is changed to Replay and thenormal
alarm concerning the replay status is shown.
•In the panel D.R. of the ship’s properties dialog, select the simulation mode.
Route alarms
•Activate the route in simulation mode and when the ship arrives to the activewaypoint,
all active alarms should be triggered.
•Activate the route in simulation mode and when the ship is out of safety passage, theXTE
alarm is shown.
Chart alarms
Set the display scale to be half the size of the compilation scale of the cell:
overscale symbolization and overscale indicator are used.
Target alarms
•Plot a manual target close to the ship’s position. Enter the speed and course of the target
and, in simulation mode, check the CPA / TCPA alarms are generated properly.
S57 CHARTS: TECHNICAL FEATURES
Standards
The ECDIS900 chart kernel comprises several hundred software components that are
compliant to the IMO Performance Standard for ECDIS, the IHO Standards S-52 V3.4 / S-57, IEC
61174 Ed.3 and IEC 672288 Ed.1.

19
ENC
It is impossible to alter the contents of the ENC. If an ENC cell is modified, the ECDIS900
detects the modification and rejects the cell during the installation procedure. Official ENC
content is converted and stored with a proprietary format. The conversion maintains the
precision of the data and does not alter the accuracy of the data.
Chart area and resolution
The chart area size of the ECDIS900 is bigger than 270 * 270 mm. The pixel size of the screen is
about 0.255 mm.

20
Presentation
ECDIS900 chart information is designed to be clearly visible for more than one observer
under different light conditions. The symbols are always drawn with the size described in the
presentation library V3.4. The character size of the text may be adjusted tobe clearly visible.
For more details, refer to the Maris ECDIS900 System Operator Manual.
All superimposed windows are temporary and can be moved and hidden at anytime. The 64
colors used for chart and MMI displays are compliant with S52Publications.
The redraw of the chart, including scale changes or scroll of the chart, never takes more than
5 seconds. During the re-generation of the data, the display is maintained until the new
display is ready for redraw.
Dangers and warnings
The Route Checking function (Route Planning and Route Monitoring) checks all dangers
inside the safety zone against the ship’s draught and air draught. The ECDIS900 senses alarms
related to both ENC cells and manual updates. The list of object classes to be warned about
by the ECDIS900 is displayed below:
