System Configuration
Other workstations connected to the ship's LAN can run ECDIS900 or ARPA2000 applications
and share and display the same data than the workstations installed in the bridge.
N
AVIGATION DATA
Navigation data are acquired by serial lines connected either to the Monitoring station or to
the NetPc.
Two applications called Sensor Monitor running on the two workstations are in charge of
analysing and transmitting the analysed data.
All analysed data (Position, time, Course and speed, Depth, Targets etc..) are sent on the LAN
in broadcasting mode and all computers of the Network running ECDIS900 can use them.
S
ET UP
The set up of the serial input to the Monitoring station is done by the installer and can be
modified at any time using SMonitor application.
The set up of serial input to the NetPC is done when the system is set up. Because there is no
monitor and keyboard the set up cannot be modified easily.
There are two ways to change it:
Connect a monitor and mouse\keyboard and access the application SMonitor
•
Use the application WinVNC on the Monitoring station and access to the NetPC remotely.
•
This requires that WinVNC is installed as server on the NetPC and as client on the
Monitoring station.

ADAR IDEO DATA
Radar video is acquired on the NetPC using the PC Radar Kit and the application
Extractor\Tracker (E\T). The video is digitised on the NetPC and sent on the LAN.
In normal mode the video is sent on the ship's LAN in braodcasting mode and all PCs of the
LAN can use and display the Radar video picture using the application ARPA2000 or overlay
the Radar video on top of the electronic chart in ECDIS900.
However the traffic on the LAN increases significantly and in some cases the traffic increase is
not acceptable. Then there are three different solutions to reduce the traffic:
1. Configure Extractor\Tracker to send the Radar video to a particular IP address (The IP
address of the Monitoring station). Then the traffic on the LAN does not increase but the
other PCs of the LAN cannot use anymore the Radar video.
2. Use a sub network as ECDIS sub network. This requires the network administrator of the
ship to set up the network with appropriate configuration and routers.
3. Install a separate network for the PCs using ECDIS900 and ARPA2000. This requires to
install Network cables (and eventually additional Network cards) to link of the Monitoring
station and the NetPC but also other PCs using ECDIS900 and ARPA2000 in the instrument
room or elsewhere.
