Getting Started
Welcome to the 1012 user guide! In order to get started, make sure you have the following hardware on hand:
- 1012 Phidget InterfaceKit
- USB cable and computer
- Something to use with the 1012 (e.g. switches and batteries)
Next, you will need to connect the pieces:
- Digital Inputs: By connecting a power supply and a switch (or the 5V pin of the 1012 and a switch) you can test the digital inputs of the 1012.
- Open Collector Digital Outputs: Connect a load (like a light bulb or LED) in series with a power supply and connect one end of the series to a digital output and the other to ground, as pictured.
- Connect the Phidget to your computer using the USB cable
Now that you have everything together, let's start using the 1012!
Using the 1012
Phidget Control Panel
In order to demonstrate the functionality of the 1012, 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 1012.
First Look
After plugging the 1012 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 If your Phidget is listed in red, your firmware is out of date.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.
Digital Input
Double-click on a Digital Input object in order to run the example:
General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:
- This is an active-high device, therefore, it will be true when connected to a high input and false when connected to ground.
Technical Details
General
All of the digital inputs have built-in filtering. This helps to eliminate false triggering from electrical noise. The input is first RC filtered by a 10k/100nF node, which will reject noise of higher frequency than 1kHz. This filter generally eliminates the need to shield the digital input from inductive and capacitive coupling that is likely to occur in the wiring harnesses.
Monitoring a Switch
Full-Sized Image
To test your digital input, wire it up to a switch as shown in the diagram. The power supply VS1 needs to be within 4.2-30V DC in order to guarantee a response from the digital input when the switch is closed.
Monitoring the Position of a Relay
If you have a double-pole relay (that is, a relay that is designed to close two switches at once with the same control input), you can switch a load with one pole, and monitor the state of the relay with the other pole. This can come in handy as a safety feature- if the relay were to fail, your software would normally not have any way of knowing.
Functional Block Diagram
Unlike typical Phidget digital inputs, these are capable of receiving up to 30VDC. These inputs are active high: A voltage of 4VDC to 30VDC will be read as True or logical 1; below 1VDC will be read as a False or logical 0. The input is high impedance, which means current flowing into the Phidget device will be limited. Ground terminals are provided in multiple locations along the input terminal strip; it is recommended that the ground terminal located nearest the input terminal be used.
