1. Introduction
The P-Sea Underwater Console is a subsea computer system designed to provide divers
with a real time interface to Tritechs range of imaging Sonar products.
Power is supplied to the P-Sea via subsea battery packs, capable of providing +24V DC and
will consume 30W (excluding any power required for connected sonars or third party sensors)
Sensors and other external peripherals can be interfaced to the P-Sea through its two serial
ports (one set to RS232 and the other set to RS485). A USB port is also provided to aid the
transfer of logged data from the P-Sea to compatible storage devices.
The RS232 ports are capable of supporting up to 115k2 Baud and can provide +12V to +36V
at 1A to power additional devices.
The USB ports support USB 2.0 devices and are also backwards compatible with older USB
devices which support the USB 1.1 specification.
The P-Sea runs a Windows® 10 embedded OS and is has been optimised to run the Gemini
Software for display and data logging. The visual display is in the form of a 7” LCD display
with a native resolution of 1024 x 768.
The processor in the P-Sea is an Intel Atom CPU with 2Gb RAM. An Internal SSD provides
a dedicated storage capacity of 80Gb.

3. Getting Started
The P-Sea has been designed with speed of deployment in mind and can quickly be rigged
up for use.
The following instructions assume that the P-Sea is being fully deployed with a Gemini 720is
Sonar, MetalSub battery packs and no Serial port devices.
3.1. Plugging in the cables
At the top of the P-Sea are the connectors for
• Serial Comms
• Ethernet Comms
• USB
• Power

Getting Started P-Sea Underwater Console
0744-SOM-00002-1 11 © Tritech International Ltd.
The SERIAL port closest to the edge of the P-Sea corresponds to COM Port 1 within
the embedded PC and is preset for RS485 communications. The SERIAL port next to the
ETHERNET port is COM Port 2 and this is preset for RS232 communications.
The USB port can be used to connect external USB devices, via its USB Cable, to the P-
Sea, such as a mouse, keyboard or external HDD. A USB Hub can be used with this port
to allow more than one USB device to be connected at any one time. This is recommended
when attempting to transfer data from the P-Sea (see Section 5.4, “ Transferring Data ”) or
attempting to use some of the more advanced features of the Gemini software (see Chapter 6,
Advanced Operation).
The USB Port must be blanked off if the unit is being submerged. The USB Cable for the P-
Sea is not rated for use underwater and is intended for dry use only.
Using the Gemini sonar cable, plug into the ETHERNET port on the P-Sea and onto the main
port of the Gemini sonar.

Getting Started P-Sea Underwater Console
0744-SOM-00002-1 12 © Tritech International Ltd.
Connect the MetalSub Power Cable to the P-Sea Power port
As no serial devices are being connected, ensure that both Serial Ports have also been
blanked off prior to the unit being submerged.

Getting Started P-Sea Underwater Console

Note
All the connectors on the P-Sea should be hand tightened, with care taken to
observe the orientation of the connectors prior to fitting.
Remove the blanking caps from the MetalSub batteries, by turning ¼ turn anti-clockwise,
and store in a safe place. Once all the other ports are connected, or blanked off, attach both
batteries to the MetalSub Power Cable.
The P-Sea will now power up, with the display showing a NO SYNC message.

3.2. First power on
Note
When powering on the P-Sea for the first time it is highly recommended that
it is done as a dry test with the USB Cable attached. This will enable you
to acknowledge any Windows® OS messages that may obscure the screen.
Typically this only needs to be done once.
When the P-Sea powers on it will show a NO SYNC message on screen. To activate the unit
fully, press and hold the POWER button for about 3 seconds.

Getting Started P-Sea Underwater Console
0744-SOM-00002-1 15 © Tritech International Ltd.
The P-Sea will now boot up the internal computer and, after a short delay, the Gemini software
will be automatically loaded.
Once fully loaded, the Gemini software will automatically detect the attached Gemini sonar
and enable it for use.

Getting Started P-Sea Underwater Console
0744-SOM-00002-1 16 © Tritech International Ltd.
If the Gemini sonar is not submerged in water, an “Out Of Water” warning will be displayed.
This will disappear from screen once the unit is submerged. Control of the Gemini sonar
and software is discussed, in depth, in Chapter 5, Basic Operation and Chapter 6, Advanced
Operation.

5. Basic Operation
5.1. Activity Indicators
At the top left of the P-Sea window there are two LEDs which are used to indicate its power
status and any activity that's being carried out.
The GREEN LED is used to indicate if power has been enabled.
The RED LED is used to indicate activity on the internal storage drives. During normal
operation this will may blink at seemingly random intervals.
5.2. User Controls
The P-Sea has a set of optimised controls for use subsea, providing a simplified interface for
performing the most common actions for controlling an attached Gemini sonar.
On either side of the P-Sea there are a series of control buttons.
