1 Introduction
The AML-3 series of instruments is a configurable family of multiparameter sondes designed for
a wide range of data collection applications. The ‘3’ designation refers to the number of sensors
that may be simultaneously installed on the instrument’s endcap. One additional sensor may be
connected externally, allowing up to 4 sensors in total.
There are two primary configurations of instruments in the AML-3 family: the AML-3 LGR, a
self-powered instrument designed for profiling applications, and the AML-3 RT, an externally
powered instrument intended for Real Time applications. While nearly identical in size and form
factor, the two 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.
Real-Time instruments (ie. AML-3 RT), in contrast, are designed to stream data while in-situ
(though they have the ability to internally record data as well). 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.
This manual describes the operation of the Real-Time version, the AML-3 RT.
1.1 Instrument Overview
AML-3 instruments are highly customizable and may be equipped with a wide range of
user-specific sensors, functionality, and features. 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.
Figure 1 depicts a typical AML-3 RT arrangement.

the 6000m, at right, the 500m.The arrangement
shown here is representative only and may differ
from the Reader’s instrument. Top left image
depicts the recommended deployment orientation -
fixed vertically with the shackle end up.
By default, AML-3 RT instruments come equipped with a shackle, a USB-C connector and a
wet-mate MCBH connector. The shackle has a hole coincident with the axis of the instrument to
facilitate suspension during deployment.

The instrument end opposite the shackle houses the sensor payload which is mechanically
protected by a thread-on sensor cage. In some configurations the cage may be different lengths
depending on the sensors installed.

1.2 Internal Battery
While an AML-3 RT instrument must use external power for operation, the instrument does
contain a small rechargeable internal battery. The internal battery is used to retain the time,
date, and configuration information when the instrument is not externally powered. The battery
also helps to provide a graceful shutdown in the event of sudden power loss. The internal
battery is not intended to sustain operation of the instrument.
The battery typically requires a charging-top up when the instrument is first received by the user.
Application of power through the MCBH connector will charge the internal battery. Note that the
instrument body may get warm during charging. This is normal and a result of the
instrument’s fast-charge capability. This behaviour does not occur during typical deployments.
The instrument has the ability to charge it’s internal battery via USB-C connector, but USB-C
ports found on many computer systems do not provide enough current to achieve this. To
charge the instrument through its USB-C port connect the instrument to an appropriate
USB-C-wall wart adapter (minimum 5W charger).
1.3 Connectors and Cables
AML-3 RT instruments come with two connectors:
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. Note: Internally logged data cannot be
downloaded with this connector (instead, use the USB-C connector).

b. AML-3 RT instruments typically come packaged 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.
c. If a serial communication cable longer than 3 metres is used then it is necessary
to add surge protection.
2. A USB-C connector with waterproof cover.
a. This connector provides power to the instrument (when connected to a
compatible USB port) and also provides high speed communications. This
connector is used for data transfer (downloading internally logged data) and
updating firmware. When connected via USB-C the provided software, Sailfish,
must be used to interact with the instrument. Note: This connector is only
waterproof when the protective cover is installed. It is not intended for use
when deployed. Do not remove the waterproof cover when the instrument
is wet.
b. AML-3 RT instruments come with a USB-C to USB-A adapter to maximize PC
compatibility. The instrument may also be connected to any USB-C port using a
standard USB-C interconnect cable, though cable length should not exceed 1m.
