VESSEL MOUNT OVERVIEW
The Vessel Mount ADCP is an ADCP intended to be mounted to a large vessel. The ADCP will
contain a bronze mounting ring and a deckbox. The bronze mounting ring is used as a stronger
support to mount the ADCP to the vessel, either within the hull or on a pole. The deckbox is an
interface box to allow communication with the ADCP.

Figure 3 Vessel Mount ADCP Flow Chart
The basic interface of a Vessel Mount system is an ADCP connected to a deckbox. The deckbox
is connected to a computer system. Peripheral devices like GPS, Gyro, and MRU are connected
to the computer. The computer is used to display the ADCP data and record the ADCP data.
You also have the option to connect the GPS directly to the ADCP through the Deckbox. The
GPS can then be used as a heading source. This will fix the magnetic interference issues caused
by the ship.

QUICK START
•Connect the ADCP to the deckbox
•Connect the GPS to the RS-232 port
•Connect the Power to the AC outlet
•Connect the RS-485-to-USB cable to the computer
oEnsure the RS-485 adapter is found on the computer
•Start Pulse software and go to terminal
•Turn on the Power switch on the Deckbox
•Click BREAK and verify you see the BREAK Statement
•Set the RS-232 port on the ADCP to match the GPS baud rate with the C232B command
oC232B 19200
•Click the “START PING” button in Pulse
•Click the Record button in Pulse at the top to begin recording the data
•Click on the VM menu button at the top to configure the other peripheral devices like
Gyro and MRU.
•Verify the data is good in the Graphical View in Pulse

ADCP
The ADCP must be mounted on the vessel so that the face of the ADCP is below the water
surface and clears the hull. If the ADCP is not installed deep enough the hull can block the
ADCP’s beams. The ADCP can be mounted directly into the hull, in a moon pool or attached to
a pole and set over the side of the vessel. The best solution will depend on the vessel and the
user. You also want to make sure no bubbles or water cavitation will pass over the ADCP. The
bubbles will cause issues with the data.
An underwater cable will be attached to the ADCP. This underwater cable will then be plugged
into the deckbox. It is assumed the deckbox will be within the vessel near a computer to
interface with the ADCP. The underwater cable length will vary based on the vessel.
Figure 4 ADCP with Bronze Plate
ADCP MOUNTING
Typically, there are 2 options to mount the ADCP: permanently or temporarily. Permanent
installs are typically done by mounting the ADCP directly into the hull of the vessel. Temporary
installs are typically done by mounting the ADCP to a pole that can be pulled out of the water.
BRONZE RING
The ADCP will ship with a bronze mounting ring. This bronze mounting ring can be used to
mount the ADCP into the hull of the ship or onto a pole.

ADCP CABLE MOUNTING
The ADCP cable will be routed from the side of the ADCP housing. The ADCP can sit flush on
the backside against a flat surface. The underwater cable connection is inserted into by a rubber
connector and a locking sleeve. The underwater cable is connected, the underwater cable is
connected to the deckbox. You may need to pass the cable through the hull of the ship. There
are different rubber glands that can be purchased to seal the underwater cable when penetrating
the ship’s hull.

You also have the option to have the underwater connector on the ADCP pointed vertically.
This could eliminate a bend in the underwater cable for installation but will increase the overall
height of the ADCP. When ordering the ADCP, you can specify this option. The ADCP can
also be retrofitted to using this connector location later if the customer decides to change the
location.

POLE MOUNT
The ADCP can also be mounted on a pole and set on the side of the vessel. This application is
typically used as a non-permanent installation. The ADCP can be raised in lowered into the
water as needed.

You can also move the mounting plate to the bottom of the ADCP and use the mounting plate as
a plate to mount to a pole.

ADCP INTERFACE
To interface with the ADCP, the ADCP is connected to the deckbox with an underwater cable.
There is one connector on each side. A Seaconn MCIL-8-F wet mateable connector and a dry
Amphenol Aerospace TP06E-12-8S(SR) connector.
Connect the underwater connector from the ADCP to the deckbox. The ADCP connector will be
a Seaconn MCIL-8-F connector. Make sure to plug the underwater connector on the ADCP
properly or it will damage the ADCP.

UNDERWATER CABLE
For underwater cables 50m and longer, we use a Falmat FM020712-6 cable. Any underwater
cable shorter than 50m will use a Southwire 570359xx underwater cable. The Falmat cable is
used for long runs because it uses shielded twisted pairs. But the Southwire has a greater bend
radius.
The underwater cable has a connector on each side. The wetside will have a Seaconn MCIL-8-F
wet mateable connector. This connector connects to the ADCP. The dryside will have a
Amphenol Aerospace PT06E-12-8S(SR) connector. This side will connect to the deckbox.

SEACONN MCIL-8-F CONNECTOR
8 Pin Seaconn cable. Please ensure to properly insert the cable. If the cable is inserted in the
wrong orientation, it will cause damage to the ADCP. Hole the rubber connector. Align the
pings with the ADCP. Push the underwater connector into the ADCP connector. Then hold on
the locking collar and thread the locking collar into the ADCP.
The locking sleeve is removeable. Inside the locking sleeve is a slip ring. The slip ring can be
removed and the locking sleeve can then be removed from the cable. Once the cable is run
through the ship, the locking ring can then be installed again.
Refer to the maintenance section before installing the connector.
