Interfacing with the LS8000-3

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 VIN input (Pin 20) or 5V if there is nothing connected to the User VIN input.

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.

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.

Direction
Inversion Setting	Measurement Direction Input	LS8000-3 Direction
Normal	Low (Disconnected or 0v)	Normal
Normal	High (5-24V)	Reversed
Reversed	Low (Disconnected or 0v)	Reversed
Reversed	High (5-24V)	Normal
