Triducer combines Speed, temperature, and Depth into one Transducer. These instructions were provided by Evan at the bottom of this ardupilot.org blog post
Mounting the triducer¶
The following example provides schematics to install a triducer on a Pixhawk and uses these parts:
A triducer. In this example, it is an Airmar DST800 triducer ;
An RS-485 TTL converter. In this example, it is MAX485 chipset based.
Parameters for this particular hawdware:
RNGFND1_MAX_CM = 700
RNGFND1_MIN_CM = 50
RNGFND1_ORIENT = 25
RNGFND1_TYPE = 17
SERIAL2_PROTOCOL = 9
SERIAL2_BAUD = 4
It is possible to connect the triducer (or other transducers) to a computer through an RS-485 to USB converter. Once it is properly working, it is possible to connect to the appropriate COM port with a 4800 baud rate.
