===About===
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.

===General===
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.

Part 1: Setup

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:

DAQ1301 Functional.jpeg
  1. Connect the DAQ1301 to the VINT Hub using the Phidget cable.
  2. Connect the VINT Hub to your computer with a USB cable.
  3. Connect a switch or digital sensor to one of the DAQ1301's inputs.


Now that you have everything together, let's start using the DAQ1301!

Phidget Control Panel

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.

Windows

To open the Phidget Control Panel on Windows, find the Ph.jpg icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

Windows PhidgetTaskbar.PNG

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 Ph.jpg 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.

First Look

After plugging the DAQ1301 into your computer and opening the Phidget Control Panel, you will see something like this:

DAQ1301 Panel.jpg


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.

Part 2: Using Your Phidget

About

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.

Explore Your Phidget Channels Using The Control Panel

You can use your Control Panel to explore your Phidget's channels.

1. Open your Control Panel, and you will find the following channels:

How do I know what channel, serial number, or hub port to use in my program?

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:

The locate Phidget button is found in the device information box

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.

Using the DAQ1301 with a Switch
DAQ1301 Switch Diagram.jpg

To interface a switch with the DAQ1301, an external voltage source must be provided to pull the input HIGH.

Detecting an External Voltage
