Getting Started

Checking the Contents

You should have received: A Phidget Interface Kit 0/16/16 A mini-USB cable		In order to test your new Phidget you will also need: A switch, a piece of wire An incandescent bulb

Connecting the Pieces

Digital Inputs: Connect the black wire (-) from the battery to the ground terminal (G). Connect the red wire (+) to one of the switch terminals. Connect the other switch terminal to the digital input terminal block number 0 using a piece of wire. Digital Outputs: Connect one of the bulb wire to the 5V terminal. Connect the other bulb wire to digital output terminal block number 3. Connect the board to the PC using the USB cable.

Testing Using Windows 2000 / XP / Vista / 7

Make sure you have the current version of the Phidget library installed on your PC. If you don't, follow these steps:

1. Go to the Quick Downloads section on the Windows page
2. Download and run the Phidget21 Installer (32-bit, or 64-bit, depending on your system)
3. You should see the icon on the right hand corner of the Task Bar.

Running Phidgets Sample Program

Double clicking on the icon loads the Phidget Control Panel; we will use this program to ensure that your new Phidget works properly.

The source code for the InterfaceKit-Full sample program can be found in the quick downloads section on the C# Language Page. If you'd like to see examples in other languages, you can visit our Languages page.

Updating Device Firmware

If an entry in this list is red, it means the firmware for that device is out of date. Double click on the entry to be given the option of updating the firmware. If you choose not to update the firmware, you can still run the example for that device after refusing.

Double Click on the icon to activate the Phidget Control Panel and make sure that the Phidget InterfaceKit 0/16/16 is properly attached to your PC.		File:1012 2 Control Panel Screen.jpg
Double Click on Phidget InterfaceKit 0/16/16 in the Phidget Control Panel to bring up InterfaceKit-full and check that the box labelled Attached contains the word True. To test the digital input, toggle the switch on and off. When on, a tick mark will appear in the Digital In box and the on-board LED will also turn on; the tick mark will disappear when the switch is off and the onboard LED light will go off. To test the digital output, put a tick mark in the digital out box and both the on-board LED and the incandescent bulb will turn on. If you click on the box again the tick mark will go away and both lights will turn off. The bottom row shows the status of the request, while the top row displays the status of the digital output as reported by the device.		File:1012 2 InterfaceKit Screen.jpg

Testing Using Mac OS X

1. Go to the Quick Downloads section on the Mac OS X page
2. Download and run the Phidget OS X Installer
3. Click on System Preferences >> Phidgets (under Other) to activate the Preference Pane
4. Make sure that the Phidget InterfaceKit 0/16/16 is properly attached.
5. Double Click on Phidget InterfaceKit 0/16/16 in the Phidget Preference Pane to bring up the InterfaceKit-Full Sample program. This program will function in a similar way as the Windows version.

Using Linux

For a step-by-step guide on getting Phidgets running on Linux, check the Linux page.

Technical Details

Digital Inputs

There is built-in filtering on the digital input, to eliminate false triggering from electrical noise. The digital input is first RC filtered by a 10K/100nF node, which will reject noise of higher frequency than 1Khz. This filter generally eliminates the need to shield the digital input from inductive and capacitive coupling likely to occur in wiring harnesses.

Monitoring a Switch

To test your digital input, wire it up to a switch as shown in the diagram. The power supply VS1 needs to be within 4-30V DC in order to guarantee a response from the digital input when the switch is closed.

Monitoring the Position of a Relay

Monitoring the position of a double-pole relay.
Full-Sized Image

If you have a double-pole relay (that is, a relay that is designed to close two switches at once with the same control input), you can switch a load with one pole, and monitor the state of the relay with the other pole. This can come in handy as a safety feature- if the relay were to fail, your software would normally not have any way of knowing.

Unlike typical Phidgets Digital Inputs, these are capable of receiving up to 30VDC. These inputs are active high: A voltage of 4VDC to 30VDC will be read as True or logical 1; below 1VDC will be read as a False or logical 0. The input is high impedance, which means current flowing into the Phidget device will be limited. Ground terminals are provided in multiple locations along the input terminal strip; it is recommended that the ground terminal located nearest the input terminal be used.
