If you need to read a whole bunch of logic-level signals, this input module adds sixteen active-high digital inputs using just one port on your VINT Hub. They're also more resilient than a VINT port running in digital input mode, able to withstand up to 30V. Whether you're reading buttons, switches, or logic-level outputs from other devices, this module offers the most efficient use of your VINT ports.
The VINT port on this board is electrically isolated from the digital inputs, preventing instability from ground loops. Each input is also isolated from one another, cutting down on cross-channel interference.
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.
Welcome to the DAQ1301 user guide! In order to get started, make sure you have the following hardware on hand:
Next, you will need to connect the pieces:
Now that you have everything together, let's start using the DAQ1301!
In order to demonstrate the functionality of the DAQ1301, 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.
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
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 DAQ1301.
After plugging the DAQ1301 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:
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
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:

Before you can access the device in your own code, and from our examples, you'll need to take note of the addressing parameters for your Phidget. These will indicate how the Phidget is physically connected to your application. For simplicity, these parameters can be found by clicking the button at the top of the Control Panel example for that Phidget.
In the Addressing Information window, the section above the line displays information you will need to connect to your Phidget from any application. In particular, note the Channel Class field as this will be the API you will need to use with your Phidget, and the type of example you should use to get started with it. The section below the line provides information about the network the Phidget is connected on if it is attached remotely. Keep track of these parameters moving forward, as you will need them once you start running our examples or your own code.
You are now ready to start writing your own code for the device. The best way to do that is to start from our examples:
This Phidget is compatible with the DigitalInput Examples.
Once you have your example, you will need to follow the instructions on the page for your programming language to get it running. To find these instructions, select your programming language from the Software Overview page.
The DAQ1301 features sixteen isolated digital input terminals. Each input is isolated from all other inputs, which allows a single device to connect to a variety of sources, and prevents cross-channel interference.
Each input is active-high, meaning the (+) terminal must be pulled at least 2.5 volts above the (-) terminal to register as TRUE.
Here are a few things you can do with the DAQ1300 Digital Input Phidget
To interface a switch with the DAQ1301, an external voltage source must be provided to pull the input HIGH.
All inputs on the DAQ1301 are isolated from one another, so a variety of signals from different sources can be monitored with a single device.
The DAQ1301 can be used without additional circuitry to detect the presence of a voltage on a line (from a power source or a signal), by wiring the input terminals to the line and its corresponding ground.
