Interfacing with the LS8000-3

Shutter Control (Pin 17)

All Class 3B laser products are required to have a shutter to terminate the laser beams before exiting the product. The LS8000-3 uses a spring-loaded rotary solenoid as a laser shutter. The spring-loaded action ensures that when power is not applied to the shutter circuit, the shutter remains closed.

Note: To open the shutter, connect the shutter control pin (Pin 17) to ground (Pin 11, 19, or 21).

Length Reset Input (Pin 18)

This is an optically isolated input that can be used to externally control the Length Reset 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.

The Length Reset input is used to reset the current length count to zero. This is the length that is reported over RS-232, RS-422, and Ethernet. The pulse outputs are not affected by this input.

This can also be accomplished through the "R" command of the serial command set (see the Communication Protocol section) for more information on interfacing with serial commands.
