Properties

OutputCount

public function get OutputCount():int

Gets the number of digital outputs supported by this board.

Antenna

public function get Antenna():Boolean

Gets the antenna state.

LED

public function get LED():Boolean

Gets the onboard LED state.

TagPresent

public function get TagPresent():Boolean

Gets whether a tag is currently being detected by the reader.

Antenna

public function set Antenna( val: Boolean ):void

Sets the antenna state. Note that the antenna is initially disabled and must be enabled before any tags will be read.

Parameters

val	antenna state

LED

public function set LED( val: Boolean ):void

Sets the onboard LED state.

Parameters

val

led state

Functions

getLastTag

public function getLastTag():PhidgetRFIDTag

Gets the last tag read. This tag may or may not still be on the reader.

getOutputState

public function getOutputState( index: int ):Boolean

Gets the state of a digital output.

Parameters

index

digital output index

setOutputState

public function setOutputState( index: int,
val: Boolean ):void

Sets the state of a digital output.

Parameters

index	digital output index
val	output state

write

public function write( tag: PhidgetRFIDTag,
lock: Boolean = false ):void

Write a tag.

Parameters

tag	tag string and protocol.
lock	lock the tag from being written again. Defaults to FALSE.
