The DAQ1200 allows you to connect 4 digital inputs; connect switches, buttons, or any device with a 5V 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 DAQ1200 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 DAQ1200!.
In order to demonstrate the functionality of the DAQ1200, 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 DAQ1200.
After plugging the DAQ1200 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.
Read four digital output devices with the DAQ1200. This Phidget is best suited for reading switches, or 5V logic level devices.
The DAQ1200 is an active-low device. You interact with the DAQ1200 through the Digital Input Channel Class. The Digital Input state equals true when grounded and false 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":
For more information about Digital Inputs, take a look at the Digital Input Primer.
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 DAQ1200, simply connect the switch across the input and ground terminals for a channel.
The DAQ1200 can also detect signals from 5V logic level devices. Be aware that the input is active-low, which means that LOW voltages will be detected as TRUE, and HIGH voltages as FALSE.
In some applications, particularly where there is a lot of electrical noise (automotive), or where you want maximum protection of the circuitry (interactive installations, kiosks), electrical isolation buys you a huge margin of protection.
If wired according to the diagram, driving the LED will cause the DAQ1200 to report TRUE.
Note that in cases where many isolated inputs are required, or for simplicity's sake, you may want to consider using the DAQ1300 or DAQ1301, which are (more sophisticated) ready-made isolated digital input Phidgets.
