Property reference

	Properties
	Interface
Decides which IrDA interface IC we wish to communicate via.
	Baud Options
Baud rate option selector
	Baud Rate
	Data Bits
Number of data bits
	Echo
Echo selection
	Connections
	Channel
UART Channel selector Software channels are bit banged using generic I/O pins but are not as reliable as hardware channels. Hardware channels use the selected peripheral on-board the target microcontroller.
	TX
Pin to be used for Transmit data
	RX
Pin to be used for Receive data
	Use Flow Control
Flow Control (Handshake) enable or disable. On: Two I/O pins are used to control the flow of data in and out of the device. Off: Flow control is disabled.
	Simulations
	Label
Label used to help identify the component on the panel.
	Scope Traces
Selects if the scope traces are automatically added to the data recorder window or not. Simulation - draws an approximation of the UART data onto the scope trace. ICT - sets up the scope trace for incoming data and adds UART packet decoding at the correct BAUD.
	Console Data
Selects if the console data is automatically generated or not
	Console Columns
Number of characters that can be displayed on a single line of the console.
	Data Source
Simulation data source used to allow the component to connect to various remote devices Nothing - Simulation data is ignored COM port - Routes the communication data to and from a physical or virtual COM port API - Routes the communication data via a data API component on the Panel.
