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:
|Image||Part Number||Price||Number of VINT Ports||Controlled By|
|HUB5000_0||$60.00||6||Local Network (Ethernet or Wi-Fi)|
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.
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":
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.
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.
