The frequencies are channels that the IR Locator 360 uses to tell the difference between 
IR emitting sources. Both 600Hz and 1200Hz IR signals may be present at the same time 
which results in two identifiable IR sources. 
Heading: 
The heading value is returned in degrees and ranges from 0 to 71 at a resolution of 5°. If 
an object were to circle the sensor in a clockwise direction, the value of degrees will 
increase. If the object were to circle in a counter clockwise direction, the value of the 
heading will decrease. 
Strength: 
The strength value represents the distance of the IR source out to a range of about 3m. 
When no IR source is detected the value of the strength approaches 0. As an IR source 
get closer to the sensor the value of the strength goes to 255.
