2Safety
2.1 Electrical safety
Both the Matrix rack unit and the canister must be connected to mains protective
earth. Any interruption of the mains earth conductor will make the units dangerous
to use.
Opening either Matrix units will expose live parts. Disconnect power before
opening, allow at least 5 minutes for internal capacitors to discharge before opening.
The subsea cannister is to be connected to a fuseprotected power interface.
Recommended fusesize on 110VAC is 16A.
If it is required to apply power to an open unit this must only be carried out by skilled personnel
who is aware of the hazards involved.
High voltage: When activated, subsea connector C12 will relay the input voltage
provided to the subsea unit (85-260VAC or 120-370VDC).
2.2 ESD precautions
Both the Matrix topside unit and the canister contain ESD sensitive components. Generally, the
units should only be opened by skilled personnel in a controlled environment. If opening these
units, ESD protective measures according to " IEC 61340-5-1: Protection of electronic devices
from electrostatic phenomena –General requirements" must be followed.
2.3 Pressure canister
If there is any indication that there might have been a water leakage in the one-
atmosphere housing great care must be exercised during opening as there may be
an over pressure inside the pod. Bleed of the pressure by carefully removing the
Swagelok cap with great caution.

The connector is also supplied with an adapter to fit a Burton 5506 shellsize 20 type connector
interface. Other adapters can be provided on request.
Note: check all O-rings and O-ring seal surfaces prior to mounting the connector.
Lubricate O-rings with Molykote 1.1.1 or similar.
When installing the canister to a metal frame please note the following:
-As a general rule care must be taken that certain types of different metals are not in
contact with each other in salt water without some type of cathoddic protection.
-The canister should if possible be electrically isolated from the frame to avoid galvanic
corrosion.
-The canister should be connected to an anode bank, typical zinc anodes, on the frame.
-When mounted horisontally (lying down), the canister must be placed with the correct
side up. This is to ensure functionality of the water detection sensors. Refer to Figure 4
for details.
Figure 4 - Canister orientation
3.2.4 Fibre-optic connection
A fully transparent fibre connection is required between Fibre of the Seacon OPT-F-1 connector
in the subsea canister, and the SC connector in the topside unit.
The fibre optic budget is 26 dB, which is suitable for a typical ROV set-up with 2 slip rings and
3000m umbilical cable. Maximum received power for the fibre transceivers is -9dBm. Transmit
power is typically 0-3 dBm.
Note: If the optical loss through the system is is less than 14dB an attenuator should be added to
the fiber connection to avoid receiver saturation.
Note: When using the OPT-G-4 connector: Fibre 1 in the subsea connector is used for
communication. The remaining fibres are spare. Fibre 1 and 2 are single mode, while fibre 3 and
4 are multi mode.
The system is designed for use with single mode fibre, but can be modified for use with multi
mode fibre, by replacing the CWDMs in the bottle and topside unit.

As a general rule, the C1 and C2 Ethernet channels should be used for multi beam echo sounders
requiring Layer 2 Gigabit Ethernet, such as Reson 7125. These channels will not work with other
than Gigabit Ethernet devices, unless reconfigured.
C3 is configured for use with gyro or inertial navigation systems with Ethernet and/or serial
interface, and provide Ethernet, serial and TTL (for 1PPS sync) in the same connector. The
Ethernet channels are 10/100 Mbps Ethernet. C3 is configured with two Ethernet channels,
allowing two Ethernet devices to be connected, e.g via a split cable. Note that a gigabit Ethernet
switch is required topside to access both channels. If a 100Mbps switch is connected topside
there will be a mismatch in baudrates topside and subsea and the channel will not be accessable.
C9 is configured with a 10/100Mbps ethernet channel. It also mirrors the TTL signal sent to C10.
If installed, C4, C5 and C6 are used for HD-SDI digital video channels. They also provide
RS232 serial channels that can be used for controlling the cameras. If HD-SDI is not installed,
the connectors can provide serial channels and power and analoge video.
The remaining connectors are used for serial data. Note that C10 also provides a TTL signal. On
C3, C11, C13 and C14, the serial channel can be either RS232 or RS485, configured via the
topside software.
C1, C2 and C3 provide up to 6A of DC power (if configured for 48VDC, C3 can provide up to
3A). The remaing connectors can provide up to 2A each.

3.4.3 Configuring the outputs
Before powering up the subsea equipment, each output should be configured correctly according
to the requirements of the connected devices. Please refer to section 3.3 for considerations on
where and how to connect different types of equipment. A plan for this should be made prior to
configuring the outputs.
Important: Before powering up any sensors, make sure that the output voltages on
C1 and C2 are set to match the power requirements of the connected equipment (24
or 48 VDC). Damage to equipment may occur if powered up with incorrect voltage.
For safety reasons, 24 and 48 VDC are routed to different pins on the output connectors. Please
refer to Appendix A for pinouts.
The outputs are configured as follows:
-Press the "CONTROL" button on the top left side of the touch screen to return to the

4Operation and maintenance
4.1 Operation
The system is operated via the touch screen interface on the topside unit, or the web interface if
this is set up. On the screen, the left side buttons (CONTROL, LINK, STATUS, SETUP and
ALARM) switches between different modes. The modes are:
CONTROL : For system operation (power on/off to the various channels) and configuring of
outputs.
LINK : Diagnostics information about the fibre system
STATUS : Diagnostics information about the system.
SETUP : Setting up the network interface.
ALARM : Review and clear out alarms.
The LED indicators on the front of the unit has the following functionality:
POWER : Located on the side of the POWER button. Red colour indicates that power is
applied, but the system is off. Green colour indicates that the system is on and
ready.
When the LED is red, press the POWER button for 2 seconds to start the boot
process. The LED turns off during boot, and turns green when the system is
ready.
LINK : Green colour indicates communication between the topside and subsea unit.
ALARM : Red colour indicates that an alarm is activated. This can be water alarm,
ground fault alarm or loss of communication. Press the “ALARM” button on
the touch screen to view and dismiss the alarm.
To enable power on a subsea connector, go to the CONTROL screen and press the
corresponding button (C1, C2 etc). The button will light up when selected, and the circular
indicator will turn green when power is applied subsea. Measured current and voltage will be
displayed inside the button when on.
If the auto-reset fuse is triggered, the indicator will change to red, and the output is turned off. To
verify or change the fuse trigger current, press the “EDIT” button and review the settings (see
also section 3.4.3).
IMPORTANT: If the water alarm is triggered, the system should be retrieved to
deck immediately and opened, by authorized personell, to dry and check for
damage. Great care must be exercised during opening as there may be an over
pressure inside the pod. Bleed of the pressure by carefully removing the Swagelok
cap with great caution.

4.2 Pre-dive checks
The following should be performed prior to each dive:
1. Check that the subsea canister is properly mounted and connected to cathodic protection
2. Ensure that the air vent fitting is firmly capped
3. Ensure that the end cap is properly mounted
4. Check and hand-tighten all connectors
4.3 Post-dive checks
The following should be performed after each dive:
1. Rinse the outside of the subsea canister with fresh water
2. Visually check for damage, scratches and pitting corrosion
3. Check all cables for wear or damage and hand-tighten all connectors
4.4 Cables and connectors assembly and disassembly
It is important for the reliability of the system that cables and connectors are assembled and
disassembled in a proper way.
Before assembly of cables please note the following points:
1. Ensure that the cable integrity are intact and that no pins are damaged or corroded.
2. Clean surface and pins with a suitable electro cleaner, type CRC 2.26 or equal.
3. Dry off with clean cloth or compressed air.
4. Grease the rubber section of the connector with a thin layer of Molycote 111 or equal.
5. Assemble the connector and tighten by hand.
6. All connectors that are not used must be plugged with depth rated dummy
connectors.
Important: Never use any kind of tool to tighten any of the connectors.
After the first dive it is important to check and tighten all connectors as they may appear to be
loose due to the influence of the water pressure during the dive.
When disconnecting any connector, check for damage and corrosion. If the connector will be
disconnected for a longer period, it is important to cover the unprotected parts using a suitable
dummy or protection cap.

4.5 Maintenance, storage and transport
After each dive, the subsea canister should be inspected for scratches in the anodising and pitting
corrosion (ref chapter 4.3). Severe scratches in the aluminium, especially near connectors or
other materials, may lead to local pitting corrosion, and should be coated with Alodine
Anodizing touchup pen, or similar (Not applicable for titanium).
If pitting corrosion is found near seal surfaces, the unit must be inspected for seal integrity
prior to diving. Contact Innova or the local Innova representative for service.
Prior to storage, the following should be performed:
1. Disconnect all cables.
2. Clean the system with fresh water.
3. Dry off with a clean cloth or compressed air.
4. Maintain cable and connectors according to section 4.4 above.
Transportation and storage should be done in the supplied Pelicase
Before use after storage, or if the subsea unit has been opened, a vacuum test should be
performed to ensure that the O-rings seal properly. Follow these instructions:
1. Connect a vacum-pump with manometer and a valve to the Swagelok fitting.
2. Evacuate air from the housing until the pressure in the housing is approximate -0.5 bar.
3. Close the valve andnote the exact pressure.
4. Stop the pump.
5. Leave the housing for one hour.
6. Verify that the reading from the manometer is unchanged.
If the pressure drops, open the housing and check and clean all O-rings and O-ring surfaces.
Lubricate O-rings with Molykote 111 or similar. Repeat the vacuum test.
CAUTION: Do not power on the Matrix bottle when under vacuum.
