If you need to expand the number of digital inputs on your VINT Hub, this module provides four extra inputs at minimal cost. Switches, buttons, or any device with a logic-level output can be read by these inputs. The DAQ1200 connects to a port on a VINT Hub. See the "comaptible products" tab for a list of hubs.
If you need isolation, compatibility with higher voltages, or more digital inputs per VINT port, have a look at the "Other Digital Inputs" tab for more options. If you plan on counting pulses on a high-frequency signal (faster than 500 Hz) or to measure pulses shorter than 2ms in length, you'll want to use one of our specialized frequency counter Phidgets instead.

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. If you would like to follow along, first 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.
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:
The DAQ1200 features four digital input terminals, all of which share a common ground. Each input has a built-in pull-up resistor to allow for easy interfacing to all manner of switches.
Here are a few things you can do with the DAQ1200 Digital Input Phidget
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.
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.
