You should have received: A PhidgetRFID A USB Cable		In order to test your new Phidget you will also need: A compatible RFID tag

Connecting the Pieces

Connect the PhidgetRFID board to the computer 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 PhidgetRFID-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If an entry in this list is red, it means the firmware for that device is out of date.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 RFID is properly attached to your PC.
Double Click on Phidget RFID in the Phidget Control Panel to bring up RFID-full and check that the box labelled Attached contains the word True. Click on the Antenna Enabled box to enable the antenna. Click on the LED Enabled box to turn the LED on or off. The Output 0 box controls the +5V digital output and the Output 1 box controls the external LED digital output. Bring an RFID tag close to the PhidgetRFID board and check that the identification string is displayed. Make sure that the Antenna is enabled for this step. When the Keyboard Output is Enabled, the identification string will also be displayed at the cursor point in an application running in active window on the PC (such as a word document, for example).

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 RFID is properly attached.
5. Double Click on Phidget RFID in the Phidget Preference Pane to bring up the RFID-full Sample program. This program will function in a similar way as the Windows version.

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

Returns the number of digital outputs available on this PhidgetRFID. These are the outputs provided by the terminal block.

bool OutputState (int OutputIndex) [get,set]

Sets/Returns the state of an output. True indicates activated, False deactivated. False is the default state.

bool AntennaOn() [get,set]

Sets/Returns the state of the antenna. True turns the antenna on, False turns it off. The antenna if by default turned off, and needs to be explicitely activated before tags can be read.

bool LEDOn() [get,set]

Sets/Returns the state of the onboard LED. True turns the LED on, False turns it off. The LED is by default turned off.

string LastTag () [get]

Returns the last tag read. This method will only return a valid tag after a tag has been seen. This method can be used even after a tag has been removed from range of the reader.

bool TagStatus() [get]

Returns the state of whether or not a tag is being read by the reader. True indicates that a tag is on (or near) the reader.

Events

OnOutputChange(int OutputIndex, bool State) [event]

An event issued when an output has changed.

OnTag(string) [event]

An event issued when a new tag is seen by the reader. The event is only fired one time for a new tag, so the tag has to be removed and then replaced before another OnTag event will fire.

Note: it is very important not to block in this event, or you will receive extra attach / detach events.

OnTagLost(string) [event]

An event issued when a tag is removed from the reader.
