Annotations page

When you study an echogram, it is often useful to add personal comments to it. Comments can be used to identify specific events such as specific echoes, unusual bottom conditions, or simply for keeping track of time or distance. The Annotations choices allow you to type comments and annotations into the echograms. The comments are automatically saved when you enable raw data recording.

Prerequisites

Several of the pages in the Installation dialog box are not available when your EK80 system is set to Replay mode.

How to open

This page is located in the Installation dialog box. To open, select it on the Setup menu.

Description

The Lines page in the Echogram dialog box allows you to enable or disable annotations in the echograms. Several different annotation types may be added to the echograms or other views. They are displayed on the views if this annotation feature is enabled. Annotations can only be added to views while in Normal operational mode.

When you save raw data, the annotations you have defined are stored as annotation datagrams.

Note

When you work in the Installation dialog box, you must always select Apply to save the changes made on a page. You must do this before you continue working on a different page.

You can add annotations manually, or import information as datagrams using a serial or LAN (Ethernet) communication port. To connect and set up the actual interface, use the Sensor Installation page. The Sensor Installation page is located in the Installation dialog box. To set up the communication parameters, use the I/O Setup page. The I/O Setup page is located in the Installation and Output dialog boxes.

Tip

Sometimes it can be useful to place a single written comment on the echogram. The Manual Annotation dialog box offers that function. Type a text string. Select OK in the dialog box to add the text to your echogram. The Manual Annotation dialog box is opened from the Setup menu

Details

Event

The Event parameters initiate annotations whenever something happens. Events may be triggered by external devices, set by a timer, or initiated by selecting Event on the top bar.

Number

All events are identified with a number. This number can be included in the annotation string.

Using this feature, you can manually select the next number to be used, and you can choose to have the number series decrease instead of increasing.

Text

Use the options in this group to select which items to be included in the event generated annotation string. You can also add a text string to be included at every event annotation. If you do not have a computer keyboard connected to your EK80 system, select the Keyboard button to open an on-screen keyboard.

Timer

Set a time period for automatic generation of events.

Latest Annotation

This text box automatically displays the latest annotation text that was typed.

Supported datagram formats for annotation data

The EK80 system supports the following datagram format for annotations:

•

ATS Annotation datagram format: ATS Annotation is a proprietary datagram format created by Kongsberg Maritime. It allows you to import text annotations from external devices.
