CONEX-LDS Controller GUI Manual
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.

CONEX-LDS Controller GUI Manual
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.
2.0 Installation
2.1 Install CONEX-LDS Graphical User Interface
Following are steps to install CONEX-LDS GUI:
•For 32 bit, Select and launch “CONEX-LDS Utility Installer Win32.exe”. For 64
bit, Select and launch “CONEX-LDS Utility Installer Win64.exe”.
•A window opens up showing Install welcome page.
•Click on “Next”.
•A window opens up allowing destination folder selection. By default it is showing
C:\.
•Click on “Next”.
•Ready to install window opens up. Click “Install”.
•Then installation starts, wait for completion. Click on “Finish” to finalize the
installation.
32 bit installer will be installed “Newport.CONEXLDS.CommandInterface.dll” in
GAC_32 folder and 64 bit installer will be installed the dll in GAC_64 folder.

4.2 Configuration
The Configuration tab allows the user to View or Change: logging configuration
parameters and instrument settings. Read only values are displayed for the log file
name and log file path.
The Logging Level can be selected from a drop down list that ranges from the Trace
level, which logs everything (….) to the least detailed, Critical Error.
The Polling Interval defines the delay, in milliseconds, between each polling event.
The user may change the polling interval by entering a new value.
To Save Changes
The Save button saves the current settings to the configuration file.

The Main tab displays the main controls in the Controller GUI similar to the virtual
front panel in Lab view. It is updated at every polling event.
4.3.1 Target tab
This tab shows the current position in (X, Y), refreshed at every PollingInterval cycle.
The current position is represented by a point. Four automatic zoom levels are
available to change the scale of the display.

4.4 Calibration
The Calibration tab is to be used to verify that the CONEX-LDS is still within the
calibration set at the factory.
Last calibration date
Last calibration date performed at the factory for the CONEX-LDS instrument.
Next recommended calibration date
The Last and Next calibration dates are set in the LDS instrument during factory
calibration. The next calibration date display color indicates the following:
•Green: there is plenty of time to schedule the next calibration.
•Orange: the next calibration date is getting close.
•Red: calibration is due.
NOTE
Newport recommends performing factory calibration EACH YEAR.

Start performance verification Button
Opens a user-friendly interface to validate the CONEX-LDS calibration. The label on
the button changes to “Stop” to cancel the current calibration verification process.
•Error ≤3% = GREEN indicator, OK
•Error > 3% = RED indicator, consider sending the CONEX-LDS to the factory for
calibration
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.

4.5 Acquisition
4.5.1 CONEX-LDS Acquisition tab
In the Acquisition tab, two acquisition methods are available:
1. Manual acquisition: “Manual trigger” button
2. Dynamic acquisition: “Dynamic trigger” button (changes to “Stop” during
acquisition)
The dynamic acquisition rate depends on the polling interval defined in the
Configuration tab.
Dynamic trigger Button
This button starts running a succession of acquisition defined by:
•A number of points defined by the “Nb points” field
•The default delay value is set to 100 ms. This value is limited by the computer and
the communication rate. The save button allows saving the X and Y data as well as
the time. This time stamp will help get an idea of system performance by setting
the delay to 1 ms (minimum value). The maximum rate is in the range of some
tens of Hertz.
Manual trigger Button
This button triggers the acquisition of the current CONEX-LDS position (one shot).
Clear” button
This button clears all acquired positions.
Reset zoom Button
Resets the zoom scale.
EDH0331En1032 — 12/18 12

CONEX-LDS Controller GUI Manual
Save Button
This button saves the acquired positions in a text file. The format is as follows:
1. Acquisition type (manual or dynamic)
2. Date and time
3. Comment: Comment line
4. Nb points: Number of points
5. Period (ms): Polling delay in milliseconds
6. Low pass filter (ms): low pass filter frequency in ms

Sets a new window of axis positions based on start and end points (XY) defined with
the mouse cursor click.
NOTE
The “Reset zoom” button automatically resets all zooms.

4.5.2 XPS Data Logger tab
This function is available only if an XPS Universal Motion Controller is physically
connected and configured in the Configuration tab.
The “Run” button starts the acquisition with the XPS. Once clicked, the “Run” button
changes to “Stop”. The “Stop” button aborts the current XPS acquisition.
The results are saved in an XPS data file.
NOTE
For additional information on the XPS and to download the manual, visit
newport.com.
Three available triggers:
1. Immediate
2. Start on TRIG
3. Synchronized on TRIG
In all 3 cases below, the analog outputs of the CONEX-LDS must be connected to
GPIO2 of the XPS at AI1 and AI2. The default pins can be changed in the
configuration tab to AI1 thru AI4 (pins 14 to 17).
EDH0331En1032 — 12/18 14

CONEX-LDS Controller GUI Manual
Start on trig mode always refers to the TTL input 1 of GPIO1 to GPIO4 connectors.
GPIO1 is the default, which can be changed in the configuration tab.
•GPIO1 TTL input1 = pin4
•GPIO2 TTL input1 = pin3
•GPIO3 TTL input1 = pin9
•GPIO4 TTL input1 = pin1
1) Immediate TRIGGER (Standard XPS gathering)
•Number of points
•Frequency
2) Start on external TRIGGER (Standard XPS gathering)
•Number of points
•Frequency
3) Synchronized on external TRIGGER (TRIG IN : External gathering)
•Number of points
•The Synchronized on Trig mode refers to the "Syncro input" pin6 of TRIG IN
connector in the XPS.
15 EDH0331En1032 — 12/18

CONEX-LDS Controller GUI Manual
The result of the acquisition using an immediate trigger or starting on an external
trigger can be displayed in the XPS gathering display feature. See below. For
acquisitions using synchronized on external trigger, the data will be stored in the
GatheringExternal.dat file found in the ftp site of the XPS.
To properly display the results in the XPS interface, gains must be properly set. Refer
to the CONEX-LDS Users Manual for the correct gains to use with the analog
outputs.
