interconnect cable even when the USB-C cable is connected to the PC. Only one
communication cable (USB-C or the DB9) should be connected to the PC at a time.

1.4 Auxiliary Sensors

It is possible for AML-6 instruments to be equipped with sensors which are not installed on the
instrument sensor endcap, such as Dissolved Oxygen (DO) and PAR sensors. 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. 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 does 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 guard.

1.5 UV biofouling control

AML-6 instruments are frequently equipped with AML's UV biofouling control technology, which
consists of a titanium housing with LEDs behind a glass window. The LED puck is oriented such
that it illuminates the critical surfaces of the sensor payload. A plastic S clip secures the stem to
the sensor cage. All surfaces with a direct line of sight to the LEDs 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-6 RT instruments are shipped from the factory with all sensors
pre-installed and configured.

1.6 Indicator LED Flash Patterns

The instrument is equipped with a multi-colour indicator LED, located adjacent to the shackle.
The tables below describe the pattern and colour indications.
