1. Introduction

The Aqua TROLL 500 is a versatile five-port multiparameter sonde. With four interchangeable sensors, this customizable device provides live readings of multiple parameters through our app. The dive log offers insightful plots of all the parameters.

It is possible to use the Aqua TROLL 500 with a DVL, gripper, and top-mounted external devices. If used with a DVL or UGPS, the parameter readings will be linked to the drone's position at any given time. Using the free software program QGIS, you can visualize the parameter values in a map. See Using QGIS to visualize dive log data in 2D and 3D for a complete guide.

2. How to install the Aqua TROLL 500

Aqua TROLL 500 is compatible with all Guest Ports (GP1, GP2, GP3).

We recommend reading the Aqua TROLL Quick Start Guide and User Manual to familiarise yourself with the probe before continuing with the Blueye-specific installation instructions.

Installation steps

Power off the drone.
Remove the battery cover.
Unscrew the 3 screws that hold the side covers and open them both.
Slide off the ballast weights.
Remove the buoyancy element so you can see the Guest Ports.
If the bottom front mounting point is not already installed:
1. Remove the front cover by removing the 4 torx screws.
2. Insert the circular clamp mount on the bottom alumnium tube so it aligns with the angled edge. Tighten the two screws so it sits firmly.
3. Attach the bottom front mounting point with a single bolt.
4. Reassemble the front cover.
Connect the smart connector of the Aqua TROLL cable to a guest-port. In the image below, the smart connector is connected to the middle guest-port. Do not tighten the screw too hard. Finger-tight is recommended to not damage the connector plugs.
Route the cable along the yellow tether cable as shown in the image.
Insert the buoyancy elements, and make sure you use the new one with a cut-out for the Aqua TROLL cable on the left side of the drone.
Close the side covers
Slide in the Aqua TROLL mounting skid with the Aqua TROLL attachednto the mount on the bottom of your X3 drone.
Put the battery cover back on.
Connect the communication cable to the Aqua TROLL probe.
Power up the drone.
That's it, and when you open the Blueye App, you will see a new settings page for the Aqua TROLL.

Ensure that sensors, or sensor plugs, are completely inserted into the ports of the Aqua TROLL, so that no liquid can enter the instrument.

Mounting the DVL onto the Aqua TROLL skid

If you are using the Aqua TROLL 500 together with the DVL, follow these steps:

Remove the steel skid of the DVL
Route the cable of the DVL as usual. See DVL A50 user guide for more information about the DVL.
Lay the drone on its side and place the DVL in front of the drone.
Slide the Aqua TROLL skid into the mount on the bottom of the drone.
Slide the DVL into the Aqua TROLL skid below the Aqua TROLL probe.

3. How to use

Changing sensors

Disconnect the cable to the Aqua TROLL.
Unscrew the big screw above the connector.
Pull out the Aqua TROLL from the mechanical skid.
Follow the guide from In-Situ attached below. (Also found on page 32 in the Aqua TROLL 500 manual, see Documents):

App usage

Aqua TROLL settings page

Once the Aqua TROLL is connected to a guest-port a new page in the settings menu called "Aqua TROLL" will be visible in the app. In this page you are able to see what sensors are currently connected. In the top menu, you can tap on the names of the sensors to get more information.

All the sensors-pages are structured equally, and you can see the serial number and sensor ID of each sensor. Some sensors need calibration from time to time, which will be displayed here if its relevant for the sensor. On the same page, you will also see a list of all the parameters related to the sensor. You can select which parameters you want to see in the dive view, the parameter name, live readings from the senso,r and the unit. Some parameters support multiple units, and this can be set from the dro- down menu.

Keep in mind that changing the units will also change the values in the log file, so we recommendsetting the units before a dive and leainge them unchanged.

Dive view

In the dive view, you can see the parameter readings selected in the settings page. You can select as many parameters as you'd like, and if you select more than three, simply swipe horizontally to see the other parameters.

Dive log

When the log files are synced after a dive, you can explore the dive details. View interactive graphs of the parameter values in full screen, and export the log file as CSV for further data analysis. See Using QGIS to visualize dive log data in 2D and 3D for more information about data visualzationg.

4. Calibration of the Aqua TROLL 500

Connect the Aqua TROLL to a Guest Port of the Blueye X3.
Disconnect the Aqua TROLL connector on the probe, unscrew the big screw on the mounting skid and pull out the probe.
Connect the connector on the probe again and power on the drone and the surface unit.
In the Blueye app, start dive and go to the Aqua TROLL settings page.
Click on the "Calibrate Sensor"-button. This will disable communication between the Aqua TROLL and the Blueye app, but provide the probe with power. This allows you to connect the probe to your phone using Bluetooth.
Install the VuSitu app from Apple App Store or Google Play.
Each sensor needs different types of calibrations, so follow the instructions from page 35 in the Aqua TROLL 500 manual found in Documents.
After calibration, go back to the Blueye App and click on the "Enable Sensor"-button again to enable communication with the Blueye app.
