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.

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.
