Measurement Direction Input (Pin 14)
This is an optically isolated input that can be used to externally control the
Measurement Direction feature of the LS8000-3. The input requires a voltage
high (5 to 24V) to activate. The input level should be the same as the voltage
connected to the User V

Optically Isolated Input Schematic
There are two ways to reverse the direction of the LS8000-3's measurements:
1. Modify the Direction Inversion setting with LaserTrak (or using the "A"
serial command)
2. Connect 5-24V to the Measurement Direction Input
Changing the Direction Inversion setting with LaserTrak to invert the direction has
the same effect as changing the state of this input.
the same effect as changing the state of this input.
Note: If the Direction Inversion setting is set to "Reverse +/- Directions" and
the Measurement Direction Input is high, they will cancel each other
out and the LS8000-3 will operate in the default manner.
