	Simulate Comms
Allows the communications to be simulated to either see the waveforms on the data recorder or to drive an injector component.
	Console Data
Selects if the console data is automatically generated or not
	Scope Traces
Selects if the component pin connections are automatically generated on the data recorder window or not. Yes: Automatically add the component pins to a group on the data recorder which will reflect the sim data during simultion. No: Do not show the pin signals on the data recorder window.

Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
