Sensor Specific Considerations
The Ai1 is often supplied with the DB600 buoy and instrument tube for deployment as a complete system. For quick
start instructions for the DB600 and associated sensors, refer to
www.measci.com/DB600_quickstart.pdf
. A wide
variety of water quality instruments can be mounted in the 105mm ID instrument tube on the DB600.
7.1
Wiring
Sensors are often supplied pre-wired and
pre-programmed. To see the sensor
wiring requirements, refer to the top of
the program loaded on the Ai1. If a
bulkhead connector is used, these are
almost always supplied pre-wired,
especially with the Ai1POLE. Refer to Table 3 on page 22 for details on the M12 Universal Wiring System.
7.2
Water Quality Sondes
The Ai1 is commonly used with water quality sondes that report a wide variety of data with various measurement
units, using SDI12. It is possible to detail the sequence of these parameters and their measurements units at each
stage in the program, or to treat the Ai1 as a black box with the measurements being named only once they arrive at
the web portal. The black-box method is recommended and illustrated here.
7.2.1
Eagle.io Configuration
Navigate to the Water Quality parameters (WQ1 through to
WQ10), right click and select
Rename
. For any that are not
used (i.e., if the sonde reports seven parameters, WQ8 through
to WQ10) select Delete and these parameters will be removed.
Rename each point to describe the parameter, such as
Turbidity. It is also useful to add a number so that these
parameters appear in sequence, and at the top of the
navigation tree under the Ai1.
Ai1 reads via SDI12,
saves to generic
WQ() and sends to
web portal.
