The DAQ1301 allows you to connect 16 digital inputs -- connect switches, buttons, or any device with a logic-level output. This Phidget connects to your computer through a VINT Hub.
This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:

Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.
The DAQ1301 has 16 digital input ports. This Phidget is best suited for reading switches, digital sensors, or external voltage signals up to 30V DC. The device's input-to-input isolation makes it great for projects that use multiple power sources.
The DAQ1301 is a high active device. You interact with the DAQ1301 through the Digital Input Channel Class. The Digital Input state equals false when grounded and true when connected to a high voltage.
You can use your Control Panel to explore your Phidget's channels.
1. Open your Control Panel, and you will find the following channels:
2. Double click on a channel to open an example program. Each channel belongs to the Digital Input channel class:
In your Control Panel, double click on "Digital Input Isolated":
1. Setting up your Programming Environment
Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.
1. Open the Control Panel and double-click on the red map pin icon:
2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.
See the Phidget22 API for your language to determine exact syntax for each property.
In the Phidget Control Panel, open the channel for your device and click on the 
icon next to the data type that you want to plot. This will open up a new window:
If you need more complex functionality such as logging multiple sensors to the same sheet or performing calculations on the data, you'll need to write your own program. Generally this will involve addressing the correct channel, opening it, and then creating an Event Handler and adding graphing/logging code to it.
The quickest way to get started is to download some sample code for your desired programming language and then search google for logging or plotting in that language (e.g. "how to log to csv in python") and add the code to the existing change handler.
To interface a switch with the DAQ1301, an external voltage source must be provided to pull the input HIGH.
The DAQ1301 can be used without additional circuitry to detect the presence of a voltage (up to 30V DC) on a line (from a power source or a signal). Do this by wiring the input terminals to the line and its corresponding ground.
