3.8. Multiple Head Installation
It is possible to control and display up to four Gemini heads from one computer using the
Gemini software. In order to do this extra hardware will be required to connect the extra
Gemini heads to the system as detailed:
Using the Gemini
Ethernet Interface Box
The Ethernet Interface Box will output to a standard Ethernet
connection so on a system with multiple heads it is possible
to connect these to an Ethernet switch. The Gemini sonar is
capable of utilising the full bandwidth of the 100Mbit·s
-1
(fast
Ethernet) connection so any switch or hub (and subsequent
infrastructure) used should be rated to Gigabit speeds in order
to be able to cope with the data.
Using the Gemini Hub
Available as a separate item from
Tritech International Ltd
is a
Gemini Hub which is capable of powering and communicating
with up to two Gemini sonars. The hub also provides RS232
ports for connecting additional sensors to the system (such as
GPS or navigation sensors). For more details of the Gemini
Hub please refer to the Gemini Hub manual or contact
Tritech
International Ltd
.
It is also possible to link two Gemini 720is units together as long as at least one unit is fitted
with dual Seacon connectors in the dual Ethernet configuration:
AUX ETHERNET PORT:
CONNECTED TO MAIN PORT
OF ADDITIONAL GEMINI 720is
MAIN ETHERNET PORT:
CONNECTED TO AUX PORT
OF FIRST GEMINI 720is
MAIN ETHERNET PORT:
CONNECTED TO ETHERNET
INFRASTRUCTURE (MUX POD ETC)

Both units would be controllable through the Gemini software as if they were connected
through a standard hub.
