Introduction; Instrument Overview - AML Oceanographic AML-1 RT User Manual

1 Introduction

The AML-1 RT is an ultra-compact externally powered single port instrument that provides real
time (streaming) serial data from any AML X2change
identified by their distinct orange collars.
There are a number of common applications for these devices, including:
● Pairing an AML-1 RT instrument with a Sound Velocity sensor to provide real time sound
speed measurements for MBES applications
● Mounting a pressure sensor-equipped AML-1 RT on an underwater vehicle to stream
depth information
● Installing an AML-1 with a combined conductivity and temperature sensor to calculate
salinity data on a moored platform in real time.
The instrument relies on external power for operation and comes equipped with a single
wet-mateable connector to facilitate power and data transmission.
The instrument itself has no configuration, but instead provides access to the command prompt
of the installed sensor. Configured behaviour such as baud rate, measurement frequency,
formatting, etc, is programmed and persistent within the installed sensor, not the
AML1-RT instrument. For this reason, behaviour of the instrument may change with the
installation of a new sensor, even if the parameter is identical to one previously installed.
