Getting Started

This section details how to install, configure and get a Subsonus setup operational.

Prerequisites

The prerequisites required before interfacing with or configuring a unit include the following:

Note: It is highly recommended that the equipment be function tested in a controlled environment prior to installation and deployment. See Function Testing for wet function testing instructions.

Quick Start Guide

  1. Mount the surface unit following the guidelines in Surface Unit Mounting.

  2. Mount the subsea unit following the guidelines in Subsea Unit Mounting.

  3. Configure the devices for your desired application. See the sections found under Using the Web UI for information on configuring Subsonus. Note that the alignment configuration cannot be performed until the units are mounted.

  4. Install and set up any external aiding devices, such as a DVL, and ensure that any position and alignment offsets are accurately measured once mounted. These offsets must be later entered during alignment configuration. see Add DVL

  5. Remove the cable pigtail from the connector on the Subsonus units and the supplied cables. Install the cables to the units, ensuring that the connectors are mated correctly and the jackets are screwed on hand tight. see Connection Diagrams

    Note: The connectors used on Subsonus require silicone grease to ensure they seal correctly. Keep the sealing faces free of debris or damage and ensure the female connector is completely sealed with grease before every mating. Recommended silicone grease: Dow MOLYKOTE™ 111.

  6. Set up the reference data source, see Surface Unit Reference Source. Ensure that the alignment between the surface unit and reference source is correct and measured.

  7. Connect the Subsonus cable to PoE injector and the PoE injector into a local network (with DHCP) - see Connection Diagrams for more information. Power everything on.

    Note: When the PoE injectors are being supplied power, the DC Run LED will indicate green and when the PoE OUT is connected and power is being drawn from the PoE RUN LED indicator will also change to green. When Subsonus is on, it will beep.

  8. Open your web browser and type in the address http://surface.local/ to connect to the surface (vertical connector) Subsonus unit. The trailing forward slash is required on some web browsers.

    Note: If you cannot connect to the Subsonus at this address, see Host Name Discovery.

  9. Ensure that the previously set configurations are all correct, and that the surface (master) Subsonus is correctly set to track the target(s) e.g. Subsonus Tag or a Hydrus.

  10. Set the alignment of the surface Subsonus according to Alignment Configuration

  11. Measure the offset between the surface unit reference source and surface Subsonus unit. This is a critical measurement.

  12. Add the reference source as an aiding device for the surface Subsonus, see Subsea Subsonus Aiding, ensuring that the offsets are correctly entered in the web UI.

  13. Open your web browser and type in the address http://subsea.local/ to connect to the subsea (horizontal connector) Subsonus unit. The trailing forward slash is required on some web browsers.

    Note: If you cannot connect to the Subsonus at this address, see Interfacing with Subsonus

  14. Set the alignment of the subsea Subsonus according to Alignment Configuration

  15. Configure any subsea external aiding devices, see Subsea Subsonus Aiding, ensuring that the offsets are correctly entered in the web UI.

  16. The system is now ready to deploy. Click on the Main page to see the status. It may take a couple minutes to initialise, after which time the location of the surface and subsea units will appear in the web UI.
