DST1200 User Guide
Required Hardware
- An DST1200 Sonar Phidget
- A VINT Hub
- A 3-wire sensor cable
- A USB cable
- A computer
Connecting the Pieces
- Connect the DST1200 to the VINT Hub using the sensor cable.
- Connect the VINT Hub to your computer with a USB cable.
Testing Using Windows
Phidget Control Panel
In order to demonstrate the functionality of the DST1200, the Phidget Control Panel running on a Windows machine will be used.
The Phidget Control Panel is available for use on both macOS and Windows machines.
Windows
To open the Phidget Control Panel on Windows, find the 
icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel
macOS
To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the icon to bring up the Phidget Control Panel.
For more information, take a look at the getting started guide for your operating system:
Linux users can follow the getting started with Linux guide and continue reading here for more information about the DST1200.
First Look
After plugging the DST1200 into your computer and opening the Phidget Control Panel, you will see something like this:
The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:
- Serial number: allows you to differentiate between similar Phidgets.
- Channel: allows you to differentiate between similar objects on a Phidget.
- Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
Distance Sensor
Double-click on the Distance Sensor {{{2}}} object in order to run the example: [[Image:{{{1}}}_DistanceSensor_Example.jpg|center|link=]]
General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:
- Read the distance in millimetres on the right
- Move the change trigger slider to select the minimum change required to register a new distance
- Move the data interval slider to change how fast data events come in
Testing Using Mac OS X
- Go to the Quick Downloads section on the Mac OS X page.
- Download and run the Phidget OS X Installer
- Click on System Preferences >> Phidgets (under Other) to activate the Preference Pane
- Make sure your device is properly attached
- Double click on your device's objects in the listing to open them. The Preference Pane and examples will function very similarly to the ones described above in the Windows section.
Testing Using Linux
For a general step-by-step guide on getting Phidgets running on Linux, see the Linux page.
Using a Remote OS
We recommend testing your Phidget on a desktop OS before moving on to remote OS. Once you've tested your Phidget, you can go to the PhidgetSBC, or iOS pages to learn how to proceed.
Technical Details
Current Consumption
The current consumption of the DST1200 varies depending on the data interval you choose. The longer the interval between samples, the lower the current consumption. Switching to quiet mode also lowers current consumption slightly.
Amplitude Response
When you receive data from the DST1200, you'll end up with an array of sonar reflections that each have a distance and an amplitude. The distance, of course, refers to how far away the object is. The amplitude gives you a general idea of the size of the object. The amplitude value can range from 3 to approximately 900, with 3 being a very small reflection and 900 being a very large one. In most applications, when you're using the DST1200 as an ordinary distance sensor, you'll probably want to ignore all reflections except for the one with the greatest amplitude.
