Getting Started

Checking the Contents

You should have received: A PhidgetInterfaceKit 0/0/4 A Mini-USB Cable		In order to test your new Phidget you will also need: 9V battery A battery connector A 9V incandescent bulb with wires

Connecting the Pieces

Connect the red/positive (+) wire from the battery connector to OC (Common) connector on the InterfaceKit. Connect the black/negative (-) wire from the battery connector to one of the bulb wire. Connect the other bulb wire to the NO (Normally Open) connector on the InterfaceKit. Connect the InterfaceKit to your 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If an entry in this list is red, it means the firmware for that device is out of date.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 Phidget InterfaceKit 0/0/4 is properly attached to your PC.
Double Click on Phidget InterfaceKit 0/0/4 in the Phidget Control Panel to bring up InterfaceKit-full and check that the box labelled Attached contains the word True. Click on the first Digital Out box. Atick mark appears in the box and the bulb lights up. Click on the box again. The tick mark goes away and the light goes out. If you unplug the USB cable while the light is on, it will go 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. Move the positive (+) wire from NO to NC (normally closed). The light is now on when the Digital box has no tick mark. Clicking on the box turns the light off. If you unplug the USB cable when the light is on, it will stay on.

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 0/0/4 is properly attached.
5. Double Click on Phidget InterfaceKit 0/0/4 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.

Technical Details

Relays

A relay is an electrically-controlled switch. Although many types of electrical switches exist, a relay’s mechanical nature gives it the advantage of reliability and current-switching capacity. The main disadvantage to using mechanical relays is their limited life-span, as opposed to solid state relays who do not suffer from this drawback. For more information about how relays work and how to use them, check the Mechanical Relay Primer and the Solid State Relay Primer.

Wetting Current

When a relay is in one switch position for a period of time, oxidation of the open contact(s) can occur. Depending upon the internal coating material of the contacts, oxide films of varying density will be displaced upon the surface of open contacts; this film acts as an insulator to current flow. When the relay is switched, a certain amount of current flowing through the contacts, known as the wetting current, is required to remove the film of oxides and ensure proper conduction. Because of this requirement, these relays are not reliable for signal switching. Check the specification table for your relay board to find out the Minimum Load Current ("Wetting Current").

Load Noise

If highly inductive loads are used with the InterfaceKit, it is recommended that a noise limiting component be used to prevent damage to the device. An MOV, TVS diode, or kickback diode (for DC applications) shunted across the load will assist in dissipating voltage transients.

API

We document API Calls specific to this product in this section. Functions common to all Phidgets and functions not applicable to this device are not covered here. This section is deliberately generic. For calling conventions under a specific language, refer to the associated API manual in the Quick Downloads section for that language. For exact values, refer to the device specifications.

Functions

int OutputCount() [get] : Constant = 4

Returns the number of digital outputs supported by this PhidgetInterfaceKit.

bool OutputState (int OutputIndex) [get,set]

Sets/returns the state of a digital output. Setting this to true will activate the output, False is the default state. Reading the OutputState immediately after setting it will not return the value set - it will return the last state reported by the Phidget.

Events

OnOutputChange(int OutputIndex, bool State), [event]

An event that is issued when the state of a digital output changes.
