Micron Gemini 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.
Micron Gemini Introduction The Micron Gemini takes Tritech’s Gemini Multibeam technology and fits it in a form factor that fits with the Tritech Micron family to create the world’s smallest Multibeam imaging sonar. Having a 90° horizontal field of view and 50m end range, with an update rate up to 20Hz and incredibly compact dimensions the Micron Gemini can be used in applications where size is critical.

Micron Gemini Getting started The following instructions are to help the user connect the system together for the first time and be able to successfully power on the unit. In order to prepare the system and test its functionality before mounting to a vehicle, the Micron Gemini requires either an Ethernet or Serial test kit (depending on user requirement).
Micron Gemini Serial System Test Kit The serial system test kit has different part numbers. This reflects the different mating tails required for the connector fitted to the Micron Gemini purchased. Please reference the serial number of the Micron Gemini and connector variant when in conversation with Tritech. The following serial system tests kits are available: ...
Micron Gemini Ethernet System Test Kit The Ethernet system test kit has different part numbers. This reflects the different mating tails required for the connector fitted to the Micron Gemini purchased. Please reference the serial number of the Micron Gemini and connector variant when in conversation with Tritech. The following serial system tests kits are available: ...

The system is now ready to operate with the software, green LED’s indicate the transmission and reception of data.
Micron Gemini Assembling the Ethernet System The assembly of the Ethernet system is similar to the process detailed in the Serial system Step 1 Connect the Breakout assembly to the 10m Ethernet test cable, taking care to properly align the Souriau connector and its keyway. Step 2 The connector on the Gemini and the Power Supply cable should be connected, similar to the instructions given for the Serial System setup (see ”Assembling the...
Micron Gemini Installation Communications Protocols This section details communication information that should be taken into consideration prior to installation. Serial In order to achieve the maximum performance from the serial link it is recommended that the Tritech USB adapter is used. The Tritech USB allows Genesis and the Gemini to automatically negotiate to the maximum permissible baud rate for the line.
Micron Gemini RS485 This is the preferred serial communications protocol. It is recommended that the minimum speed 921600 baud be used for best overall performance. Autocomms The Tritech USB adapter supports auto negotiation of baud rate and communications protocol. When it starts it always defaults to RS485. If RS232 is required, then you will need to left mouse click on the ID number of the Micron Gemini and select RS232 from the dropdown within the General tab.
Micron Gemini Electrical Installation For electrical installation please see the connector pinouts in “Appendix A” For the Micron connector there is a 1 metre test cable available which is terminated to a D- Type Sub-Miniature connector, see “Micron Test Cable - S11640 XXm”. Connector Maintenance Guidelines Mating surfaces should be lubricated with 3M Silicone Spray or equivalent, DO NOT GREASE.
Micron Gemini Hardware Installation To correctly mount the Micron Gemini, the blue Gemini logo/mould should be at the top, and the product label at the bottom. BOTTOM The transmit and receive elements are arranged such that they are angled at 0° about the horizontal axis which should be considered when mounting the sonar.

Micron Gemini Any metallic clamps should be electrically insulated from the sonar body by either rubber or plastic strips or mounting brackets of at least 3 mm thickness and extending at least 3 mm beyond the clamp boundary to reduce any galvanic corrosion effect. Non-metallic clamps are preferable;...
Micron Gemini Installing the Micron Gemini using Tritech Mounts There are multiple ways to affix the Micron Gemini due to its small size and versatility. Tritech have produced Mounting Bracket Kits to enable the customer to adapt to their application, giving users the ability to angle the sonar at either 0° or 10° downward tilt. There is also the Clamp Mounting Bracket which can be used where a quick release system may be more appropriate.
Page 22
Micron Gemini Fixing the Sonar Mounting Bracket to your vehicle at 0° The Sonar Mounting Bracket has both Metric and Imperial mounting hole footprints to allow easy mounting of the adapter. The following instructions assume that holes have been drilled in a mounting plate for your vehicle.
Page 23
Micron Gemini Step 3 Align the mounting holes that you want to use then fit the mounting bracket as shown onto the 10° adapter. Mounting the Micron Gemini into the Bracket Step 1 Insert the Micron Gemini as shown into the mounting bracket, making sure that the sonar is facing the correct way up.

Micron Gemini Mounting the Micron Gemini into the Clamp Mounting Bracket The clamp mounting bracket allows the user to quickly mount and dismount a Micron Gemini to their vehicle. The clamp mount bracket also allows you to fit the Micron Gemini at a 10° downward tilt. To mount the Micron Gemini onto the clamp follow the instructions below.

Micron Gemini Installing the Micron Gemini onto a Pole Mount System Tritech International Ltd have also created ancillary systems to allow users to Pole Mount a Micron Gemini. This methodology would be perfect for rapid deployment and imaging of an area where ROV access can be limited, or inappropriate.

Micron Gemini Maintenance General guidance Although the Gemini range is not field serviceable regular care and maintenance of the unit should be carried out. The sonar body and endcap are protected from corrosion by the hard anodised passive surface film. This offers excellent protection in general operating conditions. However, without routine maintenance and in extended immersion in sea water, particularly at raised temperatures and salinity, the chlorides from the salt will start to attack this passive layer.
Micron Gemini Sacrificial Anode Information There is a zinc alloy sacrificial anode fitted to the rear of the Micron Gemini which is intended to prolong its active life when submerged for long periods of time. The lifespan of the anode itself will vary greatly depending on the conditions it is exposed to, so it may need to be changed on a relatively regular basis.
Micron Gemini Pressure Sensor Maintenance (300m only) 300m rated Micron Gemini sonars are fitted with a pressure sensor. This sensor requires regular maintenance to inhibit the opportunity for crevice corrosion and salt build up within the pressure sensor port. To maintain the pressure port, first unscrew the seal screw with the S12759 Socket Tool provided (as illustrated).
The software reports that no sonars are detected Ensure that the latest revision of Genesis software is running on your computer. Visit www.moog.com/tritech to download the latest version. Check all cabling to the sonar and verify that it is powered correctly with appropriate voltage at the sonar.

Micron Gemini Sonar is present but will not ping Ensure that you have OpenGL version 2.1 or greater installed. For Ethernet systems: Check your network settings on the PC. Typing route print into the command line will show the PC routing table. The sonar and PC must be on the same subnet and the PC’s routing table needs to be set up so that packets are routed correctly to the sonar.

Micron Gemini The Micron Gemini will not connect using RS232 on my Multiplexer The issue may lie with the type of connection that you have and the way that the Micron Gemini Autocomms works. See the Autocomms sections for more details. This situation will occur mostly in multiplexer systems that utilise fibre optics, rather than a wired copper connection.
Micron Gemini Appendix A - Connector Details This appendix covers the pinouts for the various connectors and the associated wiring detail for the Micron Gemini Sonar and its peripherals. Warning Application of reverse supply voltage to the unit or supply voltage across any of the communication connections may lead to equipment damage not covered under the warranty conditions.
