CONEX-LDS

1.0

Introduction

1.1

Purpose

The purpose of this document is to provide instructions on how to use the CONEX-

LDS Controller GUI.

1.2

Overview

The CONEX-LDS Controller GUIis a software application that has a Graphical User

Interface (GUI) which allows the user to interact with the CONEX-LDS device.

1.3

Controller state diagram

For a safe and consistent operation, the CONEX-LDS uses 3 different operational states:

1.

Configuration

2.

Ready

3.

Measure

In each state, only specific commands are accepted by the CONEX-LDS. Therefore, it is important to understand the state diagram below and which commands and actions cause transitions between the different states.

1

EDH0331En1032 — 12/18


When powering the CONEX-LDS, the controller starts initialization. When initialization is successful, the controller goes to the READY state. The controller can go to the CONFIGURATION state using the PW1 command. In the

CONFIGURATION state, the CONEX-LDS allows changes to all configuration parameters, like gains or controller address. The PW0 command saves all changes to the controller’s memory and returns the controller back to the READY state.

The device goes to the MEASURE state with the LB1 command. After sending the command, the status LED blinks for 3 seconds, indicating that the laser is going to be powered. At the end of this period the LED stops blinking and the laser starts emitting. This Controller GUI will display the current X and Y positions.

Measurements can be recorded either through the command set or the two analog outputs.

REFERENCE INFORMATION

The optical wedge of the CONEX-LDS-VER calibration verification kit induces an angular deviation to the autocollimator's beam. This deviation corresponds to a measurement angle of approximately 1000 µrad. The exact angle is measured and reported in the Calibration Certificate shipped with each CONEX-LDS-

VER Kit. The user should input KitSerialNumber and ReferenceAngleValue from the Calibration Certificate in the Configuration tab. The verification process consists of 4 measurements, spaced 90° apart on the PSD. These measurements are compared to the CONEX-LDS-VER reference angle set by the user in the Configuration tab. Before performing this verification and inserting the optical wedge, the mirror must be centered so the CONEX-LDS reads X = 0 and Y = 0 ±10 µrad.
