Property reference

	Properties
	Buffer Size
The maximum number of bytes of a NMEA message we can store before processing the message.
	Log Altitude
Adds a variable to store the incoming altitude value Referenced by macro: ReadAltitude
	Log Buffer Overflow
Adds a variable to store if the incoming message buffer overflows Referenced by macro: CheckBufferOverflow
	Log Course Over Ground
Adds a variable to store the incoming course over ground value Referenced by macro: ReadCourseOverGround
	Log Dilution Of Precision
Adds a variable to store the incoming DOP value Referenced by macro: ReadDilutionOfPrecision
	Log Ground Speed
Adds a variable to store the incoming ground speed value Referenced by macro: ReadGroundSpeed
	Log Horizontal DOP
Adds a variable to store the incoming HDOP value Referenced by macro: ReadHorizontalDilutionOfPrecision
	Log Latitude
Adds a variable to store the incoming latitude value Referenced by macro: ReadLatitude
	Log Longitude
Adds a variable to store the incoming longitude value Referenced by macro: Read Longitude
	Log Satellite Count
Adds a variable to store the number of satellites in range Referenced by macro: ReadNumberOfSatellites
	Log UTC Time
Adds a variable to store the incoming UTC Time value Referenced by macro: ReadUTCTime

	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.
	RX
Pin to be used for Receive data
	Baud Options
Baud rate option selector
	Baud Rate
	Simulation
	Label
Label used to help identify the component on the panel.
	Show Globe
Allows a graphical globe to be shown on the panel along with a coordinate marker.
	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 Injector - Routes the communication data via a data injector component on the Panel.
