1 Introduction
The AML RTS series is a highly configurable family of multiparameter sondes designed for a
wide range of data collection applications. This series includes both the AML-3 RTS and the
AML-6 RTS, where the ‘3’ and ‘6’ designations refer to the number of sensors that may be
simultaneously installed on the instrument’s endcap. Additional sensors may be connected
externally, allowing up to 4 and 8 sensors respectively in total.
There are three primary configurations of instruments in the AML-3 and AML-6 family: the AML
LGR, a self-powered instrument designed for profiling applications, the AML RTS, an externally
powered instrument intended for Real Time Streaming applications, and the AML XC (Xtra
Connector), a hybrid instrument with both Logging and Real Time capabilities. While nearly
identical in size and form factor, the three configurations differ in a few key features which
specialize them for their respective applications.
Instruments with the LGR designation are self-powered via a rechargeable internal battery and
have a mechanical on/off switch adjacent to their shackle. These instruments are designed to
internally log sensor measurements and transfer data post-deployment. These instruments are
most commonly used for multiparameter profiling such as CTD, SVP, etc.
Real Time Streaming instruments, in contrast, are designed to stream data, with no ability to
internally record the data. Both power and communication to these instruments is facilitated via
a waterproof connector located adjacent to the shackle. These instruments rely on external
power for operation and the application of this power turns the instrument on in lieu of a
mechanical switch. These instruments are commonly used in moored applications, buoys,
underwater observatories, and ROVs.
Instruments with the XC designation combine the strengths from both the LGR and RTS
versions. Providing even more flexibility, it can internally record data and has the option of
streaming data in real time via a waterproof connector located adjacent to the shackle. These
instruments are used when both real time streaming and internal logging may be required.
This manual describes the operation of both the AML-3 and AML-6 Real-Time Streaming (RTS)
version.
1.1 Instrument Overview
AML instruments are highly customizable and may be equipped with a wide range of
user-specific sensors. The instrument described here is intended to be a representative
example of a typical setup and therefore may not be identical to the Reader’s. The Reader is
directed to any unit-specific supplementary documentation provided with their instrument for
information on features and functionality not described here.

instrument shown here is representative only
and may differ from the Reader’s instrument.
By default, both the AML-3 and AML-6 RTS instruments come equipped with a shackle, a
waterproof MCBH connector, and a status indicator LED. The shackle has a hole coincident with
the axis of the instrument to facilitate suspension during deployment. It is recommended the
instruments be deployed vertically with the shackle end up. The AML-6 RTS shackle is also
hook shaped to provide secure handling by a user.
AML Oceanographic Ltd. 7 / 39

The end of the instrument opposite the shackle houses the sensor payload which is
mechanically protected by a cage. The AML-3 utilizes a thread-on sensor cage, and the
AML-6 utilizes a bolted-on sensor cage. In some configurations the cage may be different
lengths depending on the sensors installed (AML-3 only) or made from a copper alloy to prevent
biofouling (AML-6 only). The default cage for both instruments uses stainless steel.
Typical specifications of an AML RTS are described in the table below.

1.2 Connectors and Cables
AML RTS instruments come with one connector:
1. A waterproof MCBH connector.
a. This connector is used to provide external power and serial communications to
the instrument during deployment. The instrument can be factory set to either
RS-232 or RS-485 full duplex. Its typical use is for the transmission of live
measurements during deployment.
b. AML RTS instruments are typically sold with a length of underwater cable which
has an MCBH series connector at one end, and a serial DB9 connector with
flying power leads at the other end. This cable provides a means to communicate
serially with the instrument and apply external power in bench top settings.
AML Oceanographic Ltd. 9 / 39

c. If a serial communication cable longer than 3 metres is used then it is necessary
to add surge protection.
1.3 Auxiliary Sensors
It is possible for AML instruments to be equipped with additional sensors which are not installed
on the instrument sensor endcap. These are referred to as auxiliary sensors and may be either
fastened to the side of the instrument body or installed on adjacent moored equipment.
AML-3 RTS instruments can accommodate one auxiliary sensor and AML-6 RTS instruments
can accommodate two auxiliary sensors for a maximum sensor load of 4 and 8 sensors,
respectively.
In all cases, auxiliary sensors are connected to the instrument via a waterproof connector on the
Connector Endcap, providing power and communication (note that Figure 1 and 2 do not show
any auxiliary sensors). It is typical for auxiliary sensors mounted on the side of the instrument to
be protected by a stainless steel or copper alloy guard.
1.4 UV biofouling control (500m Only)
AML RTS instruments are compatible with AML’s UV biofouling control technology (rated to
500m). The embodiment of this technology is a streetlamp-shaped device installed adjacent to
the sensors which blankets the sensor payload with UV, providing antifouling protection. All
surfaces with a direct line of sight to the emitting ‘head’ of the device will receive biofouling
protection, including the externally mounted auxiliary sensors. The UV biofouling system is a
factory-equipped option.
UV-equipped instruments are factory-set to emit UV-C light on a pre-programmed duty cycle
immediately on instrument powerup. Do not expose bare skin or eyes to the emitted light.
For most applications, AML RTS instruments are shipped from the factory with all sensors
pre-installed and configured.

1.6 Pressure Ratings
Pressure ratings may differ between installed sensors and the instrument body, and
deployments should never exceed the shallower of these ratings. For example, a 500 m
instrument equipped with a 6000 dBar pressure sensor is limited to deployments of 500 m depth
or less. Similarly, a 6000 m instrument equipped with a 500 dBar pressure sensor is also limited
to deployments of 500 m depth or less.
The instrument pressure rating is identified on the end of the instrument, adjacent to the
shackle. Typical ratings for AML RTS instruments are 500m and 6000m.

2 Getting Started
This section provides an overview of basic instrument operation and functionality under a
factory-default setup. Specifically, this section describes how to connect to the instrument,
change settings via interface software, and stream sensor measurements.
Details describing how to change the instrument’s configuration and behaviour are described in
the Configuration section of this document.
2.1 Deployment workflow
When deployed, power and communication must be administered via the waterproof MCBH
connector. First-time users of an AML RTS instrument are encouraged to familiarize themselves
with operation by following the workflow described below:
1. On a dry workbench, apply external power to the instrument (8-30 VCD via the MCBH
connector) and connect the instrument to a PC using the serial cable. Use the provided
software interface to explore the instrument configuration options. Details on this
process are described in the following section: Getting Started with Sailfish .
2. After configuration, verify the desired functionality in an ‘as-deployed’ state by
connecting to a serial terminal via the MCBH connector and streaming live data with the
instrument submerged in a saltwater bath. This process is described in the following
section: Getting Started with Serial Communications .
2.2 Getting started with Sailfish
The preferred (but not the only) method of communicating with the instrument is via AML’s
software interface, Sailfish; a user-friendly GUI-based platform which allows users to easily
configure an instrument, observe live sensor measurements (live data streaming), and
download logged data. Sailfish may be downloaded from the AML Oceanographic website
( www.AMLoceanographic.com ).
Sailfish provides the easiest means of adjusting the instrument’s configuration. Advanced
commands not accessible via the GUI exist and can be applied via command line. Refer to
section Configuring an Instrument in this document for more details.
AML Oceanographic Ltd. 12 / 39

To use Sailfish to configure the AML-3 and AML-6 RTS instrument, follow the procedure
described below:
1. Download the Sailfish install file from the website (or provided USB thumb drive) and
follow the on-screen installation instructions. Sailfish is compatible with Windows 7, 8, 10
and 11.
2. Connect the serial cable and apply 8-30 VDC to the flying leads.
3. Connect the instrument to the PC via the serial connection. The instrument will typically
take about 10 seconds to boot up upon the application of external power. The boot up
sequence will be displayed on the LED.
4. Start Sailfish and wait for the software to load.
5. If you open Sailfish before connecting your instrument you will need to click on the
‘Refresh’ button for your instrument to appear.
6. If recognition is successful, Sailfish will display an instrument tile with serial number in
the Devices tab. Select the corresponding tile, then press ‘Connect’ at the bottom of the
tab to establish a connection.
7. Click the gear icon on the instrument tile (top left corner of the tile) to open the
Configuration page. Follow the on-screen instructions to configure the instrument.
AML Oceanographic Ltd. 13 / 39

a. Note: A common action at this step is to tare the pressure sensor if required. This
is achieved by clicking the Gear Icon and selecting Tare Pressure Sensor.
8. The user is encouraged to explore the Instrument Settings page to familiarize
themselves with typical settings.
9. A common step is to commence real-time measurement (data) streaming from the
instrument. This is achieved through the Live Data tab in Sailfish.
To disconnect the instrument simply unplug the serial cable, or click the Disconnect button.
2.3 Getting started with a Serial Terminal
While Sailfish provides a user-friendly means of interacting with the instrument in a benchtop
environment, communication with a deployed instrument must be conducted via serial
connection through the MCBH connector. This connection type provides a command-line means
of configuring the instrument and streaming live measurements.
The command prompt also allows the use of advanced commands not available in Sailfish.
To connect to the instrument and establish serial communication:
1. Insert one end of the wet-mateable cable into the MCBH connector of the instrument.
Connect the DB9 into the computer’s serial port (or use a USB-RS232 adapter).
2. Apply 8-30V to the flying leads of the wet-mateable connector cable. The instrument will
commence its boot sequence. Typical boot time is approximately 10 seconds.
3. Use a Serial Terminal to open the appropriate COM port and establish communication
with the instrument. The default baud is 115200 (8 data bits, no parity, 1 stop bit) .
Sending a carriage return (enter key) will land the instrument at prompt.
2.3.1 Basic Command Line Functionality
The commands described in this section are intended to provide an overview of basic
functionality in order to familiarize the user. There are many commands available, however, and

The Sensor Meta Data section provides information on how to interpret the results of the Sensor
Data table immediately following. For reference, Port refers to the sensor port that a sensor is
installed into on the instrument endcap (6 ports in total on an AML-6 RTS endcap, 3 ports on an
AML-3 RTS endcap). Auxiliary sensor(s) will be listed as being installed on Port 7 or 8 on an
AML-6 RTS, and port 4 on AML-3 RTS.
In this example there are 6 sensors installed on the AML-6 RTS instrument. Port 1 (as labeled
on the endcap) has a combined Conductivity and Temperature sensor installed, so it is depicted
as two sensors - one with a Cond parameter, and one with a TempCT parameter. Likewise, Port
6 has a combined sound velocity and temperature sensor installed.
The Measurement Meta Data section provides information on how to interpret the columns of
measurements when the instrument is streaming data.
Streaming live data (MONITORING)
Live data streaming is referred to as monitoring. To commence monitoring, issue the command

...
The monitor command invokes the streaming of sensor measurements and derived parameters
if configured to do so. The instrument will continue to stream data indefinitely until manually
halted by command . Monitoring is halted by sending a carriage return (pressing enter).
The instrument can be configured to cease monitoring only on transmission of specific key
sequence, referred to as ROBUST MONITOR MODE. Refer to the Configuration section of this
document for details.
The Measurement Metadata table contextualizes the provided data columns with respective
parameters and units. In this case, column 3 (first measurement 51.281) is for parameter Cond
(conductivity) in units of mS/cm.
Monitor behaviour and output format is configurable.Refer to the Configuration section of this
document for more details.
Application note on monitor formats
While columns of data are easy to read by humans, in instances where the streaming data will
be interpreted by machines (ie. other logging devices, software, telemetry modules, etc), users
are strongly encouraged to utilize AML’s extensible format, referred to as AMLx. Refer to
Appendix B for more information.

3 Configuration
Commands can be sent to the instrument via command prompt, or with Sailfish when connected
over serial. Sailfish provides a user-friendly method of configuring basic instrument settings, but
command line-based configuration provides access to a wider range of configuration.
3.1 Configure with Sailfish
To configure with Sailfish please reference the Getting Started with Sailfish section.
3.2 Configure with a terminal
Advanced commands can be sent to the instrument via command prompt when connected via
serial connection. The commands described in this section are not an exhaustive list. Refer to
Appendix A for more details.
3.2.1 Baud Rate
Changing the instrument’s baud rate will disconnect the terminal from the instrument and will
require the terminal baud rate to be modified accordingly.
Command
Description
set baud <baudrate>
Set the serial baud rate for the instrument. All standard baud
rates between 9600 and 115200 are accepted. Default is
115200.
Note: This command takes immediate effect. Users must
change the BAUD rate of their terminal program.
3.2.2 Sampling Settings
Burst Mode and Single Mode Sampling
The instrument can be configured in two different sampling modes: Single and Burst. In Single
Mode, the instrument will output single samples at a configured interval. Burst Mode, in contrast,
provides groups of samples at configured intervals. For example, an instrument in burst mode
may be configured to output 6 samples at a rate of 2 samples/sec on 30 seconds intervals.
AML Oceanographic Ltd. 17 / 39

Figure 3: Burst mode functionality. Blue bars indicate instrument samples.
Burst mode behaviour is configured by prescribing the Number of Burst Samples, Burst Interval,
and Sample Rate, as depicted in Figure 3. The Sample Rate (frequency with which sensor
measurements are obtained) is common between Burst Mode and Single Mode.
Example:
To configure an instrument to output 6 samples at a rate of 2 samples/sec on 30 second
intervals, use the following command sequence:
>SET SAMPLE 2/S
-set the sample rate to 2 samples per second. Note that
sample rate must be set prior to enabling burst mode.
>SET SCAN MODE BURST
Scan mode: Burst
Sample rate: 2 /sec
Burst interval: 30 secs
Burst samples: 10
Burst monitor: Samples
-Set the global instrument scan mode to Burst. Monitoring
will now be in bursts.
>SET BURST SAMPLES 6
-Prescribe 6 samples for each burst.
>SET BURST INTERVAL 30
-Commence the burst every 30 seconds.
>MONITOR

-Commence streaming measurements
For the configuration of a Burst Mode to be valid, the Sample Duration of a given burst must be
less than or equal to the burst interval, B.I. This is described in the following equation.
AML Oceanographic Ltd. 18 / 39

Equation 1: Sample Duration ≤ B.I , where 𝑆𝑎𝑚𝑝𝑙𝑒 𝐷𝑢𝑟𝑎𝑡𝑖𝑜𝑛 = 𝑛
𝑆 . 𝑅
S.R = sample rate (Hz), n=number of samples
Burst Averaging
The instrument may also be configured to report a single value representing the average of the
samples within a burst (ref: SET BURST MONITOR [ SAMPLES | AVERAGE ] command). For
example, an instrument in burst mode may be configured to obtain 6 samples at a rate of 2
samples per second on 30 seconds intervals. If burst-averaging is on, the instrument will output
a single value for each parameter at 30 second intervals, where each value is the average of
the 6 samples obtained during the burst.
Burst-averaging applies only to data output during monitoring.
Command
Description
set sample <rate> [/second | /minute, /hour |
seconds | minutes | hours | max]
Set the rate at which the instrument monitors
data from the sensors. Maximum sample rate
is 20 Hz.
set scan mode [burst | single]
Switch between single and burst mode. When
the instrument is in burst mode it will sample
in bursts at a set interval. Note that the
Sample Duration must be less than or equal
to the Burst Interval (Equation 1)
set burst interval <interval>
Set the burst interval in seconds.
Minimum: 5
Maximum: 14400
set burst samples <samples>
Set the number of samples taken per burst.
Samples will be taken at the set sample rate.
Minimum: 2
Maximum: 1200
set burst monitor [samples | average]
Set whether the monitor output will display all
the burst samples or an average of the
samples.
display burst
Display the current burst mode settings.
Sleep Mode
The instrument can be configured to enter a low power state in between taking samples. The
instrument will only enter sleep mode if the sleep and sampling settings are configured so that
the sample period is longer than the minimum sleep time. By default the minimum time the
AML Oceanographic Ltd. 19 / 39

instrument is allowed to sleep is 40 seconds plus a 5 second delay after taking the sample.
Sleep mode is also compatible with Burst Mode.
Equation 2: Min Sleep Time + Sleep Delay ≤ Sample Period
Equation 3: Min Sleep Time + Sleep Delay ≤ Burst Interval - Sample Duration
Example 1:
Minimum Sleep Time = 40 s (default)
Sleep Delay = 5 s (default)
>SET SCAN SLEEP Y
-enable sleep mode
>SET SAMPLE 2 MIN
-set sample period greater than 45 seconds
45 < 120
-Equation 2 is satisfied and instrument will sleep between
taking samples
Example 2:
>SET SCAN MODE BURST
