Introduction
Purpose and scope
This document is intended to give the reader knowledge of how to operate and maintain the Aanderaa ZPulse®Doppler
Current Sensor 4420/4830/4520/4930-series. These sensors are described in a single manual since the measurement
principle and electronics is the same for all sensors. 4420 and 4830 are Shallow Water (SW) units with maximum depth
rating 300meter. 4520 and 4930 are available in two versions 3000meter Intermediate Water (IW) and 6000meter Deep
Water (DW) version. 4420 and 4520 are without temperature and are mainly used with the SeaGuard RCM to measure
current. 4830 and 4930 also measure temperature as an extra parameter.
The sensor is designed to fit directly on the top-end plate of SeaGuard or SeaGuardII Platform using a sensor foot or in
a string system connected to SmartGuard or SeaGuard String logger using AiCaP. The sensor can also be used as
stand-alone sensor using RS-232. The R-version of each sensor is only RS-422 output and is intended for stand-alone
use with longer cables than can be used with the RS-232 version. There is hardware differences between a standard
version and a R-version so this need to be specified when ordered.
Aanderaa Smart Sensors utilize common communication protocols at the RS-232 and RS-422 interface where the
Smart Sensor Terminal protocol is a simple ASCII command string based protocol and the AADI Real Time is an XML
based protocol. The common updates of these protocols are called framework 3, and was released August 2012 for
most of the Aanderaa smart sensors (See Appendix 1 Product change notification: Frame Work3). When used
together with one of the Aanderaa Dataloggers the can bus based AiCaP communication protocol is used.
To configure and control the sensor we use sensor properties. A complete list of user accessible sensor properties is
listed in chapter 1.7. The sensor properties are divided in 4 groups with different access levels. Some properties may
be set on or off when others may contain different values. To change these setting you can either use AADI Real-Time
Collector for stand-alone use described in CHAPTER 2, AADI Real-Time collector for sensor connected to SeaGuard
with plug bar assembly, SeaGuardII or SmartGuard described in CHAPTER 3, Touch screen for sensor connected to
SeaGuard with display described in CHAPTER 4 or terminal software like Terra Term for stand-alone sensor, described
in CHAPTER 6.
The sensor has 3 different alternatives for Compass calibration. This need to correspond with the installation and use,
otherwise it might be a deviation in the calculated current direction. The alternative calibration is: only up, only down or
both. This calibration can only be performed at the factory. If nothing else is specified when ordered the sensor will be
calibrated only up.

CHAPTER 1 Short description and specifications of the DCS
1.1 Description
The AADI Aanderaa ZPulse®Doppler Current Sensor is a single point current sensor based on the Doppler Shift
principle.
To measure current speed and direction the sensor transmits acoustic pulses (pings) into the water and samples the
backscattered (echo) signal at specific distance away from the sensor. Complex acoustic pulses comprising two distinct
frequencies are combined into a single acoustic pulse which is sent out in two orthogonal directions at regular time
intervals. The ZPulse®based DCS separates the received signal into different frequency bands, one for each frequency
in the transmitted signal. Further it analyses the frequency shift using a high speed Digital Signal Processor. An ARMA
based parametric model processing algorithm is used to find the Doppler frequency.
It uses four acoustic transducers (beams) but only two are necessary to be able to calculate the 2D-current. The sensor
can be configured to use all four beams or only two or three if necessary. It can also be configured to only use the 2
transducer that is pointing towards the current. This is done to avoid turbulence that might occur behind the sensor.
The sensor includes a solid-state 3-axis magnetometer and inclinometer providing the tilting and compass heading of
the sensor. The tilt is necessary for correct horizontal placement of the cell. The compass also uses the tilt internally to
find the correct horizontal components of the earth magnetic field to be able to calculate the correct compass heading
from the earth magnetic field. The compass heading and tilt (pitch, roll) is measured for each acoustic ping and is used
for calculation of the current vectors (north, east) for each ping. At the end of the recording interval a vector average is
calculated to obtain the correct averaged horizontal speed and direction. The sensor can also output the horizontal north
and east speed components in addition to the horizontal speed and direction. The sensor also calculates and outputs
several quality data which can be used to identify any suspicious data (user enabled). The different quality data from the
sensor are described in details in this manual. To minimize the effect of marine fouling and local turbulence, the ZPulse®
DCS is measuring the horizontal current at least 0.4 meter away from the instrument, refer .
In ZPulse®mode, a measurement interval comprising 150 pings (150 on each axis) will normally provide a good
estimate of the current speed. The number of pings can be reduced to lower the power consumption, but this also
increases the statistical noise (standard deviation).
The ZPulse®technology reduces statistical variance with a factor of
2
. This again reduces the required number of
Pings needed in order to achieve an acceptable statistical error.
The ZPulse®DCS 4420/4830 has POM Housing and is depth rated to 300m; All 4830 sensors and 4420 sensors has a
POM housing but titanium base plate. ZPulse®DCS 4520/4930 has a Titanium Housing and base plate and is depth
rated to 3000m or 6000m. The output formats of the 4420/4830/4520/4930 are AiCaP and RS-232, while the output
format of the 4420R/4830R/4520R/4930R are RS-422. The sensor can be used in polled mode when set to Smart
Sensor Terminal mode.
The ZPulse®DCS 4420/4830/4520/4930 fits directly onto the Top-end plate of the Aanderaa SeaGuard or SeaGuardII
data logger; the sensor is then used in AiCaP mode. When used with SmartGuard both AiCaP and RS-232 mode can
be used. The sensor may also be used as a stand-alone RS-232 sensor for other applications. The R-version cannot be
used on a SeaGuard platform. This sensor is for use with SmartGuard or as stand-alone RS-422 sensor on longer
cables. RS-422 is based on differential data transmission, which makes it more insensitive to noise than RS-232. RS-
422 was designed for greater distances and higher Baud rates than RS-232.

Page 12 February 2020 – TD 266 OPERATING MANUAL – ZPulse® DCS 4420/4830/4520/4930
Note! RS-422 must be enabled from the factory prior to delivery. Enabling RS-422 disables the AiCaP and RS-
232 interface.

1.3 Sensor pin configuration and data output
DCS 4420/4520/4830/4930 is using a 10-pin lemo plug for RS-232 and AiCaP communication between sensor and
logger; see Figure 1-5 for pin configuration. DCS 4420R/4520R/4830R/4930R is using a 10-pin lemo plug for RS-422
connection to external logger; see Figure 1-6 for pin configuration. For a list of available cables see chapter 10.2 or
contact [e-mail].

1.4 Sensor Connection
Aanderaa offers a wide range of cables for different use of the sensors, both standard cables for use with loggers using
AiCaP, RS-232 and RS-422 but also special customer specified cables for use in project. See chapter 10.2 for an
overview of standard cables or contact [e-mail] for more info. To configure the sensor it either
need to be connected to an Aanderaa logger using AiCaP, a real-time RS-232/RS-422 cable or you need a RS-232
configuration cable. This cable can be used for all sensors regardless of version since all sensors have a RS-232
connection for configuration.

1.4.1 Configure sensor using RS-232 configuration cable
The 3855 cable is a non-watertight 1.5 meter cable for laboratory use only used for connection between sensor and PC
in the office/lab. This cable can also be used to configure all other Aanderaa Smart Sensors.
The cable is supplied with a USB port providing power to the sensor but since the USB port on a computer normally
gives 5V power and the DCS needs 6-14V the sensor cannot be powered from the computer like for most other
Aanderaa Smart Sensors. A USB extension is supplied with the cable so we recommend connecting the free end to an
external power (6-14V). An alternative solution is to use a 9V alkaline battery (6LF22) to set the sensor up or log it in the
laboratory. Sensor Cable 3855 is also available in other lengths.

1.5 User accessible sensor properties
All configuration settings that determine the behaviour of the sensor are called properties and are stored in a persistent
memory block (flash). One property can contain several data elements of equal type (Boolean, character, integer etc.).
The different properties also have different access levels.
To read the value of a certain properties you need to send ASCII string starting with the command get and then followed
by the property name to the sensor, see example below.
To change the content of a property an ASCII string starting with set and then followed by the property name and new
value in brackets need to be sent to the sensor.
Get Interval//When sending this string to the sensor, it will then return the value stored in
this property.
Interval 4520 7 60 //Returned from sensor, where 4520 is the product number, 7 is the serial
number of the sensor and 60 is the value stored as interval in seconds. To
change the value you might send the following command:
Set Interval(600) //This will change the value for this property to 10 minutes
Save //Always end with save to store setting in flash
The interval will now be changed to 10 minutes.
1.6 Passkey for write protection
To avoid accidental change, most of the properties are write-protected. There are four levels of access protection, refer

A special property called Passkey must be set according to the protection level before changing the value of properties
that are write-protected, refer Table 1-4.After a period of inactivity at the serial input, the access level will revert to
default. This period corresponds to the Comm TimeOut setting, or 1 minutes it the Comm TimeOut is set to Always
On.

1.7 Sensor Properties
When using AADI Real-Time Collector you don’t need to think about the command string sent to the sensor since this is
fully controlled by the software, see CHAPTER 2 and CHAPTER 3.
Some properties of the ‘AiCaP’ sensor will not be applicable / visible when the sensor is connected to a SeaGuard,
SeaGuardII or SmartGuard Datalogger, as these properties will be controlled by the instrument.
All sensor properties are listed in chapters 1.7.1 through 1.7.4.

1.7.1 Factory Configuration
All properties in this section are Read Only, not possible to overwrite for the user. Only certified Aanderaa service
personal can alter these settings. The access level for reading the status of this properties are however different for
each property, see table for more details. In this group we find information about Software and hardware settings,
Production, Service and Calibration dates.

1.7.3 System Configuration
This group is used to control the sensor via properties for configuring mode settings, sensor setup and parameter
enabling and controlling the output from sensor. Some of the properties are only visible depending on the mode
selected or if the function is enabled or not. These properties will either be grey or not visible at all.

Mode ENUM 1
Sets the sensor operation mode (AiCaP, Smart Sensor Terminal, AADI
Real-Time and Smart Sensor Terminal FW2). AiCaP is not available on
the R-versions of the sensor. Smart Sensor Terminal is an ASCII output
when AADI Real-Time is XML output. Smart Sensor Terminal FW2 is

Enable Sleep BOOL 1
Enables sleep mode in Smart Sensor Terminal and AADI Real-Time
operation to save power (In AiCaP the sensor always tries to sleep
when not busy).
Enable Polled
Mode BOOL 1
Enables polled mode in Smart Sensor Terminal Mode. When set to ‘no’
(non-polled operation) the sensor will sample at the interval given by the
Interval property. When set to ‘yes’ the sensor will read the last
measured data on request only (use the Do Sample command). A Do
Sample command triggers the end calculations and output of data. A Do
Output command can be sent to repeat the output of the last calculated
data.
Enable Text BOOL 1
Controls the insertion of descriptive text in Smart Sensor Terminal
mode, i.e. parameter names and units. Can be used to reduce message
size.
Enable
Decimalformat BOOL 1 Controls the use of decimal format in the output string in Smart Sensor Terminal mode. Default is scientific format (exponential format).
Ping Number ENUM 1
The number of ping measurements to be executed in one interval (set
by interval property), i.e. the number of ping measurements to be
averaged in one recording. Selectable from 50 to 600. Default value is
150.
