INTRODUCTION
Purpose and scope
This operating manual describes the
Recording Doppler Current Profiler, RDCP
600, how it is used, maintained and serviced.
The RDCP 600 is an important member of
the family of Aanderaa Recording Current
Meters.
Together they cover the whole range of sea
current measurements from the surface
down to 6,000 meters depth.
Besides Doppler technology, the RDCP 600
retains several standard features of the
Aanderaa recording instruments, such as the
pressure case, compass, Windows CE
interface and the electronic board.
The RDCP 600 is one of the most advanced
product of Aanderaa Data Instruments AS to
date.
RDCP 600 has been designed for use in
bottom-mounted installations as well as in
ordinary string moorings where it may
replace multiple single-point current meter
installations.
The instrument consists of a triple processor
system capable of up to 650 MIPS,
advanced signal processing algorithms and an
embedded real-time, multithread, multi-pro-
cess operating system.
The combination of such resources produces
superior data quality as well as unsurpassed
flexibility and easy operation.
Although the RDCP 600 is primarily a self-
contained current profiling device which
stores data internally on the MMC or CF
card, it can also be used to supply data in
real-time to e.g. port offices or vessel traffic
centres.
The RDCP comes in three versions: the
300m standard POM version (Shallow
Water), the 2000m Titan version
(Intermediate Water), and the 4000m Titan
version (Deep Water) .

Basic Description of RDCP600
The RDCP 600 is a 600kHz, medium range
self recording Acoustic Doppler Current
Profiler.
It is designed using the latest advances
within the telecom and computer industry
and employs a high performance, low-power
digital signal processing system, state-of-
the-art 32-bit embedded central processing
system and Windows Embedded real-time
operating system.
The complete firmware in the RDCP 600
may be upgraded by means of the MMC or
CF slot.
The modern processor system employs an
easy to use graphical user interface that
allows the user to set up the instrument
without the need of an external computer.
An advanced beam compensation system
corrects instrument tilt and provides true
horizontal current at the desired location
even when the instrument is tilted.
This feature allows the instrument to be used
in easy to deploy in-line string moorings, in
fixed bottom installations as well as in
upside-down buoy deployments.
The RDCP 600 also allows for concurrent
measurements of multiple profile columns
with different cell size and reference.
This enables the user to monitor bottom
currents as well as currents around floating
installations without any need for post
deployment cell manipulation.
Data may be stored on high-capacity storage
cards and/or sent out in real-time on RS-232,
RS-485 or PDC-4 ports.
Currently, the supplied MMC card stores
512 Mbytes. MMC cards of higher storage
capacities that are delivered from other
suppliers are not tested together with the
MMC reader for use on the RDCP 600. The
CF can store up to 2 Gbytes.
A modern Windows based post- processing
system for PC, RDCP Studio, comes with
the RDCP 600. RDCP Studio includes 3D
visualization of current speed data.
This powerful graphical presentation gives
the user a compressed view of the current
profile in a single picture with a quick
overview of the current situation during the
deployment period.

Page 12 JANUARY 2010 - TD 220a DEPLOYMENT GUIDE, RDCP600
Multiple Columns
The RDCP 600 may be configured to deal
with several columns (profiles)
simultaneously for optimum flexibility.
Each column may be set-up with individual
cell size and cell overlap, and may further be
defined as being either instrument referred
or surface referred.
When a column is instrument referred, the
distance from the instrument to the start of
the column is kept constant; a setting which
is usually used in deep waters where the
surface is distant or when bottom currents
are to be monitored.
Surface referred columns are defined as
having constant distance from the surface to
the column. In order to achieve this, the
RDCP 600 uses the high accuracy pressure
sensor (which must be installed on the
RDCP) to calculate the distance to the
surface. It then uses this information to
move the column up and down to hold the
distance to the surface constant.
Surface referred columns are especially
powerful when you are measuring currents
close to the surface or want to monitor
current speeds at a certain depth.
Cell and Cell overlap
Cell overlap is a feature that allows the extension of one cell to
overlap its neighbouring cells (refer to the illustration to the right).
This feature improves the vertical resolution of the sea column
without sacrificing data quality.
Another advantage is the possibility to fine-tune the upper or
lower cell position so that measurement may be performed as
close to the surface or bottom as possible without facing problems
with side lobe contamination. Cell overlap may range from 0% (no
overlap) to 90% (adjacent cells overlap 90%).
By using a high cell overlap, you achieve improved near surface
measurements

CHAPTER 1 Deployment Guide
Start the instrument by pressing the power button at the rear of the instrument. Wait for
approximately 20 seconds before the LCD display at the front of the instrument is activated.
We recommend that you power the instrument from an AC/DC source when working with the
instrument in the office to avoid unnecessary drain of battery. Connect the AC/DC power cable
to the electrical terminal on the Top end plate.
IMPORTANT! Ensure that the protective cap is fitted and tightened to the electrical terminal
before deployment.

1.1 RDCP600 Primary Menu System
The RDCP 600 menu system holds the key entries for the configuration and use of the
instrument. Tapping the Menu button in the lower left corner of the LCD display activates the
menu.
The two primary menu items for configuration and use of the instrument are:
Deployment Setup
Recorder
Deployment Setup is used to configure how and how
often the instrument should measure a current profile,
and the Recorder menu is used to start a measuring
session.
Other menu items, such as Sensor Configuration, Control
Panel and Diagnostics are used for maintenance.
Tap the Help menu item to activate the online help and
select topics from the book list.
Repllog is a feature used for direct connection between
the instrument and your PC and is primary used for
service.
Data Viewer is a feature that has not yet been
implemented.

IMPORTANT!
Always scan through all the options in each page to make sure your configuration is correct.
Always tap the ‘X’ in the upper right corner of the Deployment Configuration and the Sensor
Configuration page to store settings after configuration; a message appears on the LCD screen
telling you: ‘Storing. Please wait’. If power is lost during settings or during storage of the
settings, the configuration must be repeated and stored.

1.2 Deployment Configuration
The Deployment Configuration holds an overview of the current configuration, a library system
and a set of sub-configuration menus. For parameter settings we recommend that you use the
Configuration Wizard (refer page20). Alternatively you may set the configuration for each sub-
section manually (refer page Error! Bookmark not defined.) or use an already stored
configuration (refer page 19). The items that are set up in the sections are:
Site
