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. This makes the Micron Gemini ideally suited to micro ROV/AUV’s, as well as
applications where space is restricted or weight is critical, for example on diver helmets and
pole mounted applications for Search and Recovery (SAR) operations.
The Micron Gemini communicates with Tritech’s next generation integrated software suite
Genesis using Ethernet or Tritech’s advanced Serial Multibeam Protocol (TSMP). The
auxiliary port on the sonar allows for the daisy chaining of sensors including the Micron USBL
Modem and Micron Echo Sounder. Advanced adaptive processing ensures that the most
detailed image possible is generated regardless of range. This includes automatic switching
between Compressed High Intensity Radar Pulse (CHIRP) and Continuous Wave (CW)
modes of operation to maximize image definition.
Tritech’s next generation integrated software suite Genesis is supplied with the Micron Gemini
and is available from the Tritech website, supporting all Tritech’s sensors. There is also a
Windows® and Linux Software Development Kit (SDK) for the sonar to allow users to fully
integrate the Micron Gemini into a customised system.

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).
If seeking support from Tritech, reference may be made to bench testing the unit on a short
test cable

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
Serial System”).
Step 3
The Ethernet system requires the RJ45 connector plugged into your computer
instead of the USB device.
If using the system for the first time or after installing new software. See “Setting the
computer IP address in Windows® XP” or “D - Setting the computer IP address in
Windows® 7 or Windows® 10” for information on setting up your computers Ethernet
network port.

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. The higher the baud rate the
greater the bandwidth, resulting in an increase in the image update and quality.
The serial speeds available through the Tritech USB adapter are:
115200
230400
460800
921600
2Mbps
3Mbps
4Mbps
Note
When using the Tritech USB adapter, Genesis will automatically detect the
USB hardware plugged into the PC and populate Genesis with the Micron
Gemini information.
RS232
The maximum permissible speed for RS232 is 921600 baud. This will only be achieved if the
cabling is of a sufficient quality and below a certain length.
The maximum length of standard Tritech Micron cable that will support 921600 baud is 1 m.
This means that you will not achieve the maximum RS232 baud rate with the supplied 10m
Micron RS232 test cable.

Micron Gemini
0729-SOM-00004-01 Page 17 of 46
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.
This will only be an issue on links that do not allow RS485 communication, i.e. a fibre optic
multiplexer
Serial Wiring
For wiring of the DE-9 connector please see “USB to Serial Adapter Cable Options”
Ethernet
The Ethernet adapter on the host PC must be in the same IP address range as the Gemini
being attached. Using network comms allows multiple Geminis to be integrated using standard
networking equipment.
Things to note:
The Micron Gemini works on 100BASE−TX link.
It is not recommended that you connect the Gemini units through a network hub. It is
recommended that Gemini sonar units are connected using a network switch.
Note
A network hub broadcast to all its ports and thus shares its bandwidth with
each of the ports. If multiple devices are connected then the bandwidth
allocation will be shared between devices, and so the bandwidth per device
will drop. This will negatively affect the performance of the network.
A network switch keeps records of the MAC addresses of the devices
connected so when a frame of data is received the data is sent to the
appropriate port rather than broadcast. This means that each port on a
network switch will have the maximum amount of bandwidth.
Check your antivirus situation. Firewalls will see the data from the Gemini and may
stop the broadcast message. Occasionally a firewall will allow the broadcast message
but will stop the high data rate from imaging believing it to be a denial-of-service attack.

Micron Gemini
0729-SOM-00004-01 Page 18 of 46
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.
Connectors must be lubricated on a regular basis. Clean plugs and receptacles with soap and
fresh water.
Important
When attaching a connector make sure that both connector and socket are
completely dry. Any water trapped in the connection could result in an
electrical short.
Unused connectors must have a blanking cap fitted prior to immersing in
water. Failure to do this will cause permanent damage.
If using alcohol or IPA to clean out the connector take care that it does not
come into contact with any other part of the sonar.
Ground Fault Monitoring
The power supply within the Gemini includes an electrically isolated DC-DC converter
frontend. There is a small capacitive connection between the isolated ground and the sonar
chassis which should not noticeably affect any impressed current Ground Fault Indicator (GFI)
equipment.
Power
Important
Never try to make the Gemini work down a long cable by increasing the
PSU output voltage above 48V DC.
Important
Power should only be supplied to the Gemini through the MAIN port. The
AUX port power is supplied via pass through from the MAIN port.
Warning
The Gemini PSU that is supplied with the Gemini system is intended for
INDOOR USE ONLY and should not be placed in a position where it could
get wet.

Micron Gemini
0729-SOM-00004-01 Page 19 of 46
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.
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.
BOTTOM

Micron Gemini
0729-SOM-00004-01 Page 20 of 46
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; if metallic clamps are used (especially if they are different in composition to the
material used by the sonar) they should be painted or lacquered with at least two or three
coatings.
Note
Before connecting the Micron Gemini, it is recommended that the subsea
cable connectors are examined for any damage, free of debris, clean and
dry.
Caution
The outer case of the Micron Gemini is made of anodized aluminium. When
deploying the sonar, direct contact with copper alloys such as brass or
bronze should be avoided.
