  • Page 6: Introduction

    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.
  • Page 7 - 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 internal battery is used to retain the time, date, and configuration information when the instrument is not externally powered.
  • Page 10 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.

  • Page 11: Auxiliary Sensors

    USB-C connection. 1.4 Auxiliary Sensors It is possible for AML-3 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.

  • Page 12: Pressure Ratings

    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-3 RT instruments are 500m and 6000m. AML Oceanographic Ltd. 12/44...

    Serial Terminal (such as Real Term, Tera Term, etc), the serial connector should be used. 2.2 Deployment workflow There are multiple means of communicating with an AML-3 RT instrument. Generally speaking, the MCBH connector is used in the field, either during deployments or in wet environments. The USB-C connector is generally used in lab settings, either to update firmware or download logged data.

  • Page 14: Getting Started With Sailfish (Usb-C Or Serial Connector)

    2.3 Getting started with Sailfish (USB-C or Serial Connector) 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.
  • Page 15 To use Sailfish to configure the AML-3 RT 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, and 10.

  • Page 16: Getting Started With A Serial Terminal

    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 it’s boot sequence. Typical boot time is approximately 10 seconds. AML Oceanographic Ltd. 16/44...

    Data table immediately following. For reference, Port refers to the sensor port that a sensor is installed into on the instrument endcap (6 total ports in total on an AML-RT endcap). Auxiliary sensors (such as DO and PAR) will be listed as being installed on Port 7 or 8.

  • Page 18: Streaming Live Data (Monitoring)

    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.

  • Page 42: Installing Sensors

    ● Older AML Xchange™ sensors with blue locking sleeves are not compatible with the AML-6 line of instruments. ● CT X2Change™ should be installed in AML-6 port 1 due to the mechanical fit between the sensor and the cage. All other X2Change™ sensors can be installed in any of the 6 sensor ports.

  • Page 43: Appendix E - Long Term Storage Recommendations

    9 Appendix E - Long Term Storage Recommendations AML recommends fully charging the internal battery of the instrument before storage, as well as re-charging the instrument fully every 6 months. Failure to maintain battery charge can damage the instrument. AML Oceanographic Ltd.

  • Page 44: Appendix F - Warranty Statement

    AML warrants the instrument and sensor for a period of TWO YEARS (24 months) from the date of delivery. AML will repair or replace, at its option and at no charge, components which prove to be defective. The warranty applies only to the original purchaser of the instruments and only to instruments and sensors manufactured by AML Oceanographic.
