3.Sources of Alerts
4.3.1 Safety Alerts
Chart objects are identified by the ECDIS as dangers to navigation by certain parameters, such as safety parameters, e.g. «Safety contour». Alert settings and options are adjusted in the [Safety Alerts] page of the [Monitoring] panel.
The main means of determining the safety alerts operation is the «Safety Frame».
Dangerous objects entering the Safety Frame will generate a relevant alert.
4.3.2 Generation of Safety Alerts
Safety alerts are generated for the following chart objects:
If [Highlight Danger] radio button is activated, the navigation danger will be highlighted on the chart.
Area type objects if activated under the [Area alerts] group, divided to [IMO areas] and [Additional areas].
4.3.3 Navigational Alerts
Navigational alerts are intended for alerting the navigator to the change of own ship and chart information display conditions.
If the user-set value of difference between the positioning system readings is exceeded, provided the [Prim/Sec diverged] radio button is activated, the [Position monitor] caution is generated.
«Sounder depth» is a set minimum depth, which the «Sounder depth» alarm will be generated if a shallower depth is received from the sounder.
A warning will be generated if the ship moves beyond the anchor rings.
See Unit 10.4 «Anchoring Display» for the details.
4.3.6 Route Alerts
Route alerts are generated during sailing if the ship has exceeded the boundary of a set limits:
The alert is generated according to the following principles:
If the ship’s COG deviates from the plotted ship’s course by a value exceeding the setting in the [Off leg course] input window, the «Course difference» caution will be generated;
If the ship’s deviation from the route leg exceeds the set value, the «Off-Track» alarm will be generated;
If the ship schedule is not observed, «Ahead the schedule» or «Behind the schedule» warning will be generated;
As the ship approaches the next WPT, the «Approach to critical point» warning will be generated upon approach to the WOL at the advance time (or distance) set by the user;
As the ship passes the last WPT on the monitored route, the «End of track» warning is generated.
The aforementioned alerts are enabled and their parameters are set on the [Route Monitoring] page of [Monitoring panel].
Sensor alerts indicate an absence of data from external sensors. Sensor alerts will only be generated if data is absent from a connected sensor which has been selected by the user as a data source.
Example of position sensor alerts:
«Warnings» for a position sensor selected for primary positioning and «Cautions» for a position sensor selected for secondary positioning.
If there are more than one of such warnings or cautions, they are combined in a position failure group.
POS: COG/SOG no data
Warnings are generated for sensors which have been selected as the main sensor.
If there are more than one of such warnings, they are combined into a «Sensor failure» group, example:
Cautions are generated for sensors which have been selected for as supplementary position sensor, if there are more than one of such cautions, they are combined in an «AUX Sensor failure» group.
«POS: COG/SOG no data»
Cautions are generated for the auxiliary sensors which are not directly related to the navigation.
4.3.11 Sensor Alerts – Fallback
Should the primary data source fail, the backup data source will be used automatically.
In this case a caution will be generated; example, «Position Fallback».
The ECDIS displays the vessel position, speed and course in real time on the chart, based on information received from navigational sensors.
Therefore, thorough knowledge of the management and handling of sensors and interpreting the related alarms is crucial to the safety of navigation.
5.1.1 Sensor Source Basic Data
The “Primary and Secondary Window” and the «COG/SOG/HDG/STW» window on the «Control Panel» display the basic sensor data.
5.1.2 Display Options
The navigation data can be displayed together with its sensor source in different ways:
On the «Navigator» panel from the «Multipanel Display»;
On an additional panel through the extra window button;
On the left sidebar for conning information.

When you activate the monitoring of a route, the function «Next Waypoint» on the «Monitoring» panel will be activated as well.
If you go to the «Route Data» menu on the «Multi Display» panel or the «Route» display via the left sidebar, this functionality provides you with route data to a manually or automatically selected WPT.
7.2.6 ETA Calculator
You can calculate the «ETA» and «TTG» for any WPT while sailing along an activated and scheduled route by using the calculator in the «Route Data» display of the «Control Panel».
You can enter the desired planned speed of proceeding to the specified point for the planned time of arrival (PTA) calculation.
Alternatively, enter the desired planned time of arrival (PTA) to the specified point for the speed to go (STG) calculation.
3.Own Ship Symbol
7.3.1 Ship Symbol
The Ownship can be displayed as a symbol or by contour.
Change the settings on the “Route Monitoring” page of the «Monitoring» panel.
The contour will only be displayed when the scale is appropriate to the ship dimensions.
4.Ship Direction Indicators
7.4.1 Ownship Vectors
There are 2 motion vectors:
It is possible to display the two vectors at the same time.
You can switch the ownship symbol display orientation along the ship’s true motion vector (COG) or along the ship’s heading by the “Align by” on the “Route Monitoring” page.
7.4.3 Display of Vectors
To turn the display of the vectors on or off, click the buttons in the “Ship group”: «COG» vector or «HDG» vector.
7.4.4 Vector Length Values
To change the setting for the motion vector length, use the vector dropdown box in the «Control Panel» window.
The length can vary from 1 to 24 minutes.
The value defines the length of the displayed vector.
You can set a fixed vector length value, which does not change with the chart scale (Fixed).
7.4.5 Where to find
To display the track of a manoeuvre you can activate an “Expected Motion Line” (EML) of your ownship via the [Show prediction] button on the “Predictor” page. This is found on the “Precision instruments” panel from the dropdown list of the «Multi Display Panel» window.
The prediction points are displayed in ship symbols with current maneuvering parameters for a period of up to six minutes and allows to spot turning tendencies.
7.4.6 Display of Prediction
By default, the[Outlined] button is not activated and all prediction points are displayed as a ship symbol.
Click on the [Outlined] button and all prediction points will be connected.
7.4.7 Deactivate Prediction
To deactivate the «Show prediction“ function press the button again and all prediction points will disappear.
7.4.8 Curved Heading Line
Curved Heading Lines (CHL) can be precalculated and displayed for up to two courses via the “CHL” function on the “Precision Instruments” panel. This is found in the dropdown list of the «Multi Panel» and «CHL» window in the lower section of the «Control Panel».
When AP is set ON, it is not possible to change the CHL settings.
If the AP functionality is off, you can enter appropriate parameters for up to two CHLs such as the next CTW, Radius, Length of predicted vector and delay.
Data can be entered in the text field or via ‘Play’ mode by scrolling the trackball.
7.4.10 CHL Display
The activated «CHL» is displayed in blue and the inactive «CHL» is displayed in pink.
7.4.11 Switch between CHLs
The parameters of CHL can be shown via the buttons “Show 1” and / or “Show 2”.
You can switch between the activated CHL by pressing button “Active 1/2”.
By pressing “Link” a curved headline can be generated for two upcoming courses.
5.Past Track Indicators
7.5.1 Display of Primary and Secondary Track History
Your past-track that is based on primary or secondary position source can be displayed on the “Route Monitoring” page of the «Monitoring» panel under “Past Track settings”.
The track segment can be set into different colours, select the desired colour by clicking on the «Track Color» selection box. Click on the side arrow to scroll the colour selection box.
The «Plot Interval» drop down button will show the pre-selected time of plotting interval.
Click on it and select the desired time in seconds from the drop-down list.
Select the desired time label from the drop-down list of pre-selected time label in minutes by clicking, on «Time Label» drop-down button. Use «Own ship track» input line to enter the time value which the length of the displayed own ship track will correspond to. Click on «Track history» drop-down button, a list of date will appear. Select the desired date of the track required to be displayed. Click [Focus on Track] button to display the entire own ship track for the selected date on the Chart panel.
Tick on/off the three checkboxes «Show time-labels», «Show primary track» and «Show secondary track/position» to turn on/off the display of the corresponding checkboxes from the chart panel.
What does the alert number 235 indicate
Cause No. 0
This is usually given by the router when none of the other codes apply. This cause usually occurs in the same type of situations as cause 1, cause 88, and cause 100.
What is means:
Calling end is busy.
What it means:
The equipment on the other end does not answer the call. Usually this is a misconfiguration on the equipment being called.
What it means:
This is usually a telco issue. The call never reaches the final destination, which can be caused by a bad switch translation, or a misconfiguration on the equipment being called.
What it means:
There is no place on the Public Telephone network to place the call; the call never gets to its destiation. This is usually a temporary problem.
This cause indicates that the network is not functioning correctly and that the condition is no likely to last a long period of time; e.g., the user may wish to try another call attempt almost immediately.
What it means:
This means that there is a temporary failure at the physical layer on the ISDN network. If you remove the ISDN cable from the Netopia, you would see this. It’s usually temporary.
What it means:
Just too much going on at this point on the ISDN network to get the call through to its destination.
What it means:
The switch looks at the number being dialed and thinks it is for another service rather than ISDN. If the phone number is put in the correct format, the call should be placed properly. There are no standards for this, all Telcos have their own system for programming the number formats that the switches will recognize. Some systems want to see 7 digits, some 10, and others 11.
What it means:
This is rarely seen in North America but usually means that the number that is being dialed is in the wrong format, (similar to cause 88). Some part of the format being used is not understood by either the remote side equipment or the switching equipment between the source and destination of the call.
What it means:
Like cause 1 and cause 88, this usually indicates that the ISDN number being dialed is in a format that is not understood by the equipment processing the call. SPIDs will sometimes fail to initialize with a Cause 100, or a call will fail with this cause.
What it means:
This is seen in situations where ACO (Alternate Call Offering) is being used. With this type of call pre-emption, the Telco switch operates a timer. For example, when an analog call is placed to a Netopia router that has two B Data Channels in place, the router relinquishes the second channel, but if it doesn’t happen in the time allotted by the switch programming, the call will not ring through and will be discarded by the switch.
Notes about Cause Codes over 128
Cause code values of 128 and higher aren’t sent over the network. A terminal displaying a value 128 or higher and claiming it is a cause code arguably has a bug or is implementing some proprietary diagnostic code (not necessarily bad). Some commendation has cause codes listed with numbers higher than 128, but at this time they are proprietary in nature.
The PRI equipment vendors are the most likely to use these codes as they have been using proprietary messages in the facilities data link for some time now (there is an as yet undefined area in the FDL which is big enough to carry small datagrams or messages). It is typically used to pass proprietary control or maintenance messages between multiplexers.
