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 station. All serial sensor
inputs are broadcast on the network and shared by the two ECDIS stations.
REMARK
The second DGPS is optional and the same DGPS can be used onboth stations. However it is
recommended to use twodifferent DGPS forredundancy and safer installation.
INSTALLATION
During ECDIS installation process the user has to select the option Monitoring for the
monitoring station and Planning for the other ECDIS workstations.
However it is possible to switch between Monitoring and Planning modes by right
double clicking in the window title of ECDIS and activate the menu “Set as planning
station” or “ Set as Monitoring station”. The only one Monitoring workstation can exist in
the ECDIS LAN. As soon as the Planning station is switched to Monitoring, all
monitoring functions are available on this PC.
SHARED DATA
The charts and routes databases are installed on both stations. Therefore, in case of
breakdown of the Monitoring station, the Planning station can immediately be used as main
4

Hardware Platforms
ECDIS. Then it is required to switch from Planning to Monitoring mode as described above to
access all route monitoring functions.
Planned routes
When routes have been planned on a Planning station, they can be copied to another ECDIS
workstation. Right click on the route and access menu “Synchronize”. Route will be copied to
all active ECDIS workstations. Alternatively it’s possible to import route using the following
procedure:
•On the target PC, open the dialogue Load/Unload objects panel Routes and press
Import
•Select the folder containing the route located on the Planning station: C:\\
ECDIS_userdata\Routes
•Select Routes to be imported
•Press OK and the routes are copied on the local PC.
Another way to copy a route is: right click on the route, select Synchronize; the route is
copied to all active ECDIS workstations.
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 ECDIS workstations
running on the LAN.
IMPORTANT
Activation of route is possible only on monitoring workstation.
CHARTS
To synchronize ENC or ARCS charts collections use “Copy database” function available in the
chart handling dialogue.
HARDWARE PLATFORMS
MARIS ECDIS computers come in several variants:
•Flat panel computer MK15/16:
•MARIS ECDIS900 MK15 24” 4S
•MARIS ECDIS900 MK16 19” 4S
•MARIS ECDIS900 MK5is delivered with 2diffident monitors:
•MARIS ECDIS900 with Hatteland 24" monitor
•MARIS ECDIS900 with Hatteland 26" monitor
For more information about hardware see “MARIS ECDIS installation Manual”, Chapter 1

General
User Input
GENERAL
The ECDIS900 is a window based Human Computer Interface (HCI) where operator requested
information is obtained from menus and dialogue 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
ECDIS workstation is delivered ready to work with Windows XP and Windows 7 and necessary
system drivers and libraries already installed.
When ECDIS is installed on the computer, the necessary files are copied to the hard disk and
four folders are created:
•C:\Program Files\MARIS\ECDIS900_4 or C:\Program Files(x86)\MARIS\ECDIS900_4
containing:
•The application ECDIS900 and necessary libraries in the Bin folder
•The Sensor Monitor application
•Utilities
•C-MAP library components
•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 of 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 stick or
received by email.
•To update S57 chart database when the updates are received by memory stick or email.
•To back up and restore routes, logbooks and user data stored on the hard disk.
•To 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
•To restore the hard disk when it has failed. ECDIS is delivered with a CD-ROM called
“Ghost”. This CD-ROM is a mirror of the hard disk. Running the Ghost application, you
6

Sensors
restore the complete ECDIS system (Operating system, ECDIS application, basic charts,
etc.) that has the initial configuration.
SENSORS
For a complete description of the interface between Sensors and ECDIS900 see
the
I nput /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 also for data exchange between the ECDIS Planning (Back-up) and
Monitoring stations.
INTERCOMMUNICATION
LAN communication is basic the technology used in the system for communication between
ECDIS900 applications. For example, the ECDIS application launches the application called
Sensor Monitor responsible for I/O of the system. This application runs in parallel with ECDIS
and manages serial and TCP/IP input/output. ECDIS and Sensor Monitor use TCP/IP protocol
for data and commands exchanging.
EXTERNAL DATA EXCHANGE
Monitoring and Planning stations are on the same LAN and communicated using TCP/IP
protocol:
7

Ethernet: internal and external data flow
•The two ECDIS share same sensor data information. Serial data is analysed and
broadcasted on the LAN and therefore the other ECDIS workstation can use the same
sensor input data.
•Routes are usually planned on the Planning station and then transferred to the
Monitoring station via Ethernet.
•The Monitoring station is in charge of active route and waypoint. Information about the
active route and waypoint is sent to the Planning station via Ethernet.
•Ship’s settings and Safety parameters are synchronized on the network. The ship’s
settings and safety parameters can be adjusted on the Planning station and then the
parameters will be updated on all Planning stations for a while.
•Alarm acknowledgement is also synchronized. When an alarm is acknowledged on the
monitoring station it is also acknowledged on other planning stations.
Chart databases on both ECDIS stations can be updated in two different ways:
•The update procedure can be run twice on both workstations.
•The update procedure is run once and the updated chart database transferred to the
other workstation via Ethernet.

Redundancy
Technical
REDUNDANCY
BACKUP SYSTEM
ECDIS dual systems installation includes ECDIS Monitoring station working as Master, and a
Planning station working as Slave ECDIS. The Planning station is used as backup. In case of
breakdown of the main ECDIS Monitoring station, the Planning station can immediately
replace the Master ECDIS and can be used for navigation.
CONTINUOUS MONITORING
To avoid any interruption and discontinuities in the ship’s position monitoring, the ECDIS
backup is connected to the second GPS. If the Master ECDIS breakdown occurs, the ship is
monitored on the backup system.
ACTIVE ROUTE
Monitoring workstation is responsible for the active route and waypoint. The active route and
waypoint information is sent continuously to the Planning station, which displays same route.
Any changes of active route are prohibited.
DUPLICATE DATABASES
All ECDIS stations should use the same chart databases. The user is responsible of maintaining
the consistency of the chart collections and transferring routes from the Planning station to
the Monitoring station.
LOGBOOK
The logbook database, containing all navigation information of the current voyage, is stored
on both workstations. In case of breakdown, no data is lost and the second PC continues to
store navigation data to the logbook. Time interval of logbook recording could not be
changed and is equal to 15 seconds.
SET UP
The logbook window gives access to the button Change Settings. Tick on the check box
Save in the Voyage Data recorder section to make sure that the logbook will be recorded by
VDR. A logbook recorded in VDR could be replayed in ECDIS900 together with other data.
IMPORTANT
Logbook settings are not synchronized in the LAN.

Test Facilities
POSITIONING SYSTEMS
Two ECDIS workstations are connected independently to two different GPS sensorsthrough
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 ECDIS workstations is sent to the other one by
Ethernet and vice versa. GPS2 data acquired by the second station are sent to the first one.
MASTER GPS
When two different GPS are used, a user has to select which GPS sensor is the master
positioning system, i.e. which position data is used for route monitoring calculations. At any
time a user gets information about the quality of the position calculation for the GPS and
another Master GPS can be selected if necessary.
GYRO AND LOG DATA
Gyro as source of heading are interfaced to both SIS4000 units.
SYNCHRONIZATION
Ship’s settings and Safety parameters (safety contour and safety depth) are synchronized on
the network. On the monitoring Station the ship’s settings and safety parameters can be
adjusted and regularly these parameters will be updated on all Planning Stations. Alarm
acknowledgement is also synchronized.
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 needed 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.
WINDOWS OPERATING SYSTEM CONSISTENCY
Windows XP or Windows 7 does not start up or operate correctly if any hardware components
do not initialise correctly. Start up fails if any of the files required to start Windows XP or
Windows 7 are not present in the correct folder or if one of the files has been corrupted.
CONNECTION TESTS
When one or more input and/or output devices are connected to the computer, the
connections must be tested to ensure that all is working correctly. ECDIS provides a useful
tool to help perform this test.
Hyperterminal is an application built into Windows operating systems that allows testing the
connections with input devices. If input devices are correctly connected, the Hyperterminal
displays recognisable characters. Incorrectly connected input devices will either show no
information or garbled characters.

COMPUTER HARDWARE FAILURE
AUDIBLE FAILURE DETECTION:
During the boot process an audible alarm is triggered in case of RAM or Video problems. The
sound sequences are different in accordance with the type of problem.
VISUAL DETECTION:
•If the hard disk cannot start during the boot process, a warning is displayed in grey on a
black background screen.
•During Windows operating system boot, the system displays the log of all events on a
blue background screen.
COMMUNICATION FAILURE
After Windows XP or Windows 7 has been started, ECDIS is automatically launched and the
network initialised. In case of 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, ECDIS warns
the navigator.
SOFTWARE FAILURE
Software failures are reported to the user in two different ways:
•Exception and memory errors messages are displayed in an alarm dialogue.
•The error freezes the system, for example, the mouse is still moving but menus are no
more accessible.
SECURITY
The computers running ECDIS are dedicated to navigation purposes and SHOULD NOT be
used for any other tasks.
SYSTEM SET-UP
Access to system set-up and configurations functions is restricted, the main window of ECDIS
is not resizable, hiding that window is impossible and the Windows task and the caption bars
are not displayed. Other applications are accessible only when operating Application
Manager in the Service mode. When the computer boots, ECDIS is automatically launched
and Windows system functions are not accessible when ECDIS900 is running in the
operational mode.
System hot keys are disabled
In the operational mode ECDIS900 restart and shutdown functions are available only through
the Application Manager. All windows system hotkeys are disabled.

Security
ACCESS
The two workstations are used for navigation purpose only and no other application can
interfere with ECDIS, 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. But the MBA
Application can be connected to email using a Router, configured as Firewall in order to
allow only email protocol in “Email Mode”.

STANDARDS
TheECDIS900 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. , IEC 672288 Ed.1..
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 are
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 in ECDIS900 is bigger than 270 * 270 mm.
The pixel size of the screen is about 0.255 mm.
PRESENTATION
The ECDIS900 chart information has been 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 to be
clearly visible. See User Manual for more details.
All superimposed windows are temporary and can be moved and hidden at any time.
The 64 colours used for chart and MMI displays are compliant with S52 Publications.
