SCL
Pin used for SCL (clock signal) 
SCL Remap Pin
 
Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.  
Baud Select
Baud rate option selector 
Baud Rate
Baud rate to be used 
Sensor Defaults
Sample Rate
Sets the default sample rate 
Pulse Width
Sets the default pulse width and bit depth of the sensor measurements 
High Resolution Mode
Sets if the module defaults to high or low reolution mode 
IR LED Current
Default current to drive the IR LED 
Red LED Current
Default current to drive the Red LED 
Simulation
Simulate Comms
Allows the I2C communications to be simulated and interfaced via an API component to real world hardware.
