- CHAPTER 5 MOUNTING SCANNING HEAD 5-1. Alignment of Optical Axis (LS-3060 and LS-3033 only) The LS-3060 is delivered with the transmitter and receiver (scanning head) mounted to the detachable frame. When using the LS-3060 with the transmitter and receiver removed from the frame on when using the LS-3033, be sure to align them in terms of the optical axis of the laser. (See the figure below.) Misalignment of the optical axis will cause measurement errors.

- CHAPTER 6 Listener-talker Functions Setting Functions and Outputting Measured Values or Other Data Optional Interface Boards By sending commands from an external device (computer, etc.) to the LS controller, you can remotely set the various functions, or output measured values or other data from the LS controller. * For sending commands, ASCII character codes can be used. The commands and formats are the same as those for the RS-232C. See section "RS-232C" in this manual. 
- CHAPTER 6 Optional Interface Boards When the LS controller receives serial polling signal from the controller, the LS controller transmits a status byte. The content of the status byte is as shown below. Status Byte (MSB) (LSB) DI08 DI07 DI06 DI05 DI04 DI03 DI02 DI01 0 0 0 0 0 0 RQS bit Bit DI01 is set to "1" when syntax error occures Basic Sequence When 2 or more commands are transmitted, loop 1 is executed repeatedly. 
- CHAPTER 6 Optional Interface Boards Example of Program When connecting LS controller with external computer Program The following settings are specified through the computer: DIA (segment mode), CH1=X (output channel mode), NORMAL (measurement mode), MOVE (averaging mode), 512 (the number of measurements for averaging). Then, the measured value is displayed once on the computer. 
- CHAPTER 7 HINTS ON CORRECT USE • When noise interference may occur in the surroundings, connect the LS controller to an external device (computer, etc.) using an electromagneticinterference protection cable(s). Be sure to turn OFF the power of the LS controller before connecting it to an external device. General • Supply power to the computer or other device(s) before supplying power to the LS controller. 
- CHAPTER 7 Hints on Correct Use • With the LS series, the controller and scanning head are calibrated as a pair. To satisfy the specifications, therefore, be sure to combine a controller and scanning head having the same serial number. Compatibility • The transmitter and receiver are also calibrated as a pair. • When using 2 scanning heads, connect them respectively to the specified connector port of the controller. 
- CHAPTER 8 ERROR MESSAGES H-Err • If no scanning head is connected to the controller or the connected scanning head malfunctions, an error message appears on the main display (CH1). When 1 scanning head is used: If no scanning head is connected or the connected scanning head mal functions, "H-Err" appears.

- APPENDIX A OPERATING PRINCIPLE Laser beam emitted by semiconductor is reflected first by the polygonal mirror, then by the reflector mirror. Laser beam is scanned according to the rotational angle of the polygonal mirror during this process. Then, scanned beams pass through the collimator lens so that they run parallel to each other. These beams are directed at the target and converged onto a photodiode by another lens.
