Warning Symbols

Throughout this manual the following symbols may be used where applicable to denote any

particular hazards or areas which should be given special attention:

Note

This symbol highlights anything which would be of particular interest to the reader

or provides extra information outside of the current topic.

Important

When this is shown there is potential to cause harm to the device due to

static discharge. The components should not be handled without appropriate

protection to prevent such a discharge occurring.

Caution

This highlights areas where extra care is needed to ensure that certain delicate

components are not damaged.

Warning

DANGER OF INJURY TO SELF OR OTHERS

Where this symbol is present there is a serious risk of injury or loss of life. Care

should be taken to follow the instructions correctly and also conduct a separate

Risk Assessment prior to commencing work.

1. Introduction

1.1. General Overview

The Gemini 720ik is a 2D imaging sonar. It is a multibeam sonar, offering a 120° field of view

with update rates of up to 97Hz (30Hz typical - range dependant) giving rapid feedback to

the user (hardware is capable of 97Hz, Seanet Pro is limited to 15Hz).

The system consists of the Gemini sonar head(s) and either Gemini or Seanet Pro control

and display software. The software communicates with the sonar over Ethernet (100Mbit·s-1).

The software is Windows® based and will run best on a display of resolution 1280x1024 or

greater with 32-bit colour resolution.

Note

Within this manual there may be references to the Gemini 720is Sonar. The

Gemini 720is is the larger version of the Gemini 720ik, but features many of the

same capabilities of the Gemini 720ik. Therefore where these references are

made it can be safely assumed that it will apply to the Gemini 720ik.

1.2. Communications

Communication is 100Mbit·s-1 Ethernet. When using an Ethernet connection it should be

noted that the Gemini Sonar can fully utilise a 100Mbit·s-1 link while returning the sonar data.

If the Gemini Sonar is to share an Ethernet link with other high bandwidth devices, such as

video cameras, it is recommended that the 100Mbit·s-1 devices share a gigabit (or faster) link

to the surface to reduce possible network congestion.

1.3. Electrical Connection

Please refer to Section 3.3, “Sonar Head Pin-Out Diagrams” for details on the connector fitted

and the appropriate communication mode supported.

Caution

Power should only be applied to the MAIN port of the Gemini. The AUX port, if

fitted, provides an un-regulated pass through power supply taken directly from

the MAIN port input supply - please refer to Chapter 2, Technical Specification

for more information.

1.4. Software Version

Note

The instructions within this manual apply to the following software versions:

Introduction Gemini 720ik
