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.
