Introduction and Presentation
Get a basic knowledge of the sensor.
Introduction
Marport's Catch Navigator tells you when your trawl starts to fill. Placed on the top of
the trawl codend, it monitors the amount of catch that you have and warns you when
the trawl is full. You can even use it to determine a precise amount of fish inside the
trawl net. This way, you can monitor the contents of the codend while you are fishing,
avoid problems of overfilling and increase fish survival rate inside the trawl net. It is
recommended to install several sensors along the trawl to better monitor the filling
processes.
The Catch Navigator provides a high-definition echogram image of the volume of catch
inside the codend. In order to eiciently follow the trawl descent, echogram ranges are
configurable from 5 to 160 meters. Moreover, the sensor includes an automatic range
mode: when descending, the sensor can automatically switch to a lower range of 20
meters to get sharper pictures. Optionally, it can also track pitch, roll, depth, height and
temperature data.

Applications
Examples of data received and displayed in Scala2 application.
1. Catch status: empty / 2. Catch status: full / 3. The echogram shows the codend filling
up, until the catch sensor is triggered.
Safety Guidelines
Important: To ensure proper and safe use of this equipment, carefully read
and follow the instructions in this manual.

Sensor Configuration
Learn how to configure the sensor settings.
To be able to change the settings of the sensor: Press command + A or click Menu
and click User Mode > Advanced.
Connecting the Sensor to Mosa2
To configure the sensor, you need to connect it to Mosa2 application, using either the
Dock or the Configuration Cable.
Using a Dock Charger Plug
Catch Navigator | V1 | Sensor Configuration 13

1. Connect one Dock charging plug to the sensor's endcap.
2. Mosa2 discovery page opens. The sensor is displayed.
◦Click to open the sensor
configuration page.
◦Click to show the deploy
animation on the charger plug
for 30 seconds.
Using the Configuration Cable
Simply connect the Configuration Cable from the computer to the sensor to display the
sensor configuration page on Mosa2.
Tip: Refer to the Configuration Cable Quick Reference Guide for more details
about the use of this product.
1. Move other electrical devices minimum 1 m away from the computer.
2. Connect the USB connector directly to the computer.
Catch Navigator | V1 | Sensor Configuration 14

Mosa2 opens automatically and the startup wizard is displayed. The LED on the
plug is solid blue.
3. Connect the three-pin plug to the sensor.
The LED on the plug blinks alternatively blue and green.
4. Wait a few seconds. The configuration page of the sensor is displayed on Mosa2.
The LED on the plug is solid green.
You can now configure the sensor.
Note: You can keep the Configuration Cable continuously connected by
USB, and virtually eject or connect it. When no sensor is connected to
the Configuration Cable, click Menu > Eject Config Plug or Connect
Config Plug. When ejected, you come back to the discovery page. It stays
disconnected until you virtually connect to it or manually disconnect then
connect it.

Battery Information
The battery lifetime is displayed on the first page.
Catch Navigator | V1 | Sensor Configuration 16

You can also check the battery level at anytime from the top bar:
Note: When you change settings such as the uplink power or sounding
range, it aects the battery consumption and remaining lifetime. The battery
information will update aer the sensor has been switched on and operating
for 10 minutes.
Diagnostic Information
Scala2 and Mosa2 applications warn the user in case of water ingress in the sensor.
Note: Diagnostic information is available for Marport Pro sensors (A2S and A2H
PCBA versions), from the firmware version F450-02.02.00 or later and Mosa2
version 02.11.08.
Catch Navigator | V1 | Sensor Configuration 17

In case of water ingress in the sensor, alarms are displayed in Scala2 Virtual Charger
Room, in Mosa2 and on the charger plug when connected to the sensor.
•Mosa2 displays a dialog at the start of the application and warning icon in the
toolbar and diagnostic page:
•The charger plug displays a warning icon:
When the alarm appears, take the sensor out of water immediately and contact Marport
support.
Warning: In case of water ingress in the product, do not charge it: battery may
vent or rupture, causing product or physical damage.
Configuring the Trawl Node
You need to give a trawl node to the sensor. It is the number corresponding to the
position of the sensor on the trawl.
The trawl nodes corresponding to the positions on the codend are the following:
Trawl number Node numbers
Trawl 1 1 to 6
Trawl 2 101 to 106
Trawl 3 201 to 206
Trawl 4 301 to 306
Catch Navigator | V1 | Sensor Configuration 18

Trawl number Node numbers
Trawl 5 601 to 606
1. Go to the Communication page, then click in Uplink.
2. Enter a node according to the position of the sensor on the trawl.
Important: Make sure to put the same number when adding the sensor
to Scala2 receiver page. If not, change it accordingly.
Catch Navigator | V1 | Sensor Configuration 19

3. Click .
Configuring the Uplink Frequency and Power
Configure the settings of the communication link between the sensor and the vessel.
1. Go to the Communication page, then click in Uplink.
2. Enter a frequency for the communication with the vessel. Default is 44,000 Hz.
3. Drag the slider to change the power of the uplink signal.
Note: A higher level of uplink power reduces the battery lifetime.
