Copyright ©2014-2017 Scanse LLC - www.scanse.io 

Sweep can be connected to low level micro 
controllers directly using its serial port, or to a PC 
using the provided USB to serial converter. 
 

 

             Figure 4, Sweep Cable Diagram 

Sweep has two serial port connectors with identical 
signals. This allows for more mounting options.

Goes high when first range 
measurement of new scan is 
completed, then goes low when 
second range measurement is 
completed. Remains low until next 
rotation. Line is only active when 
scanning and low when not.
