Page 4: Introduction
At the heart of the PSD Reader device lies a microcontroller, which handles all communications over the USB interface and over the I2C or SPI bus. For reading input signals or acquiring data, the PSD Reader is equipped with an 8-channel, 16-bit ADC with an input range of +/-10V. -

Page 7: Connection Of The Psd Reader
4 Connection of the PSD Reader The PSD Reader is commonly used to set the gain of the PSD detectors and read out the position and angle data. For this purpose the PSD detector is connected via Sub-D 15 HD cable (1:1 Pin connection) to the PSD Reader. -

Figure 8 Y-configuration 4.2 PSD Reader with DAC (optional) If ordered the PSD Reader can equip with a 4 channel digital-to-analog converter, providing +/-10 volts per channel. The output voltages can be controlled via Kangoo Software or coupled to the measured pointing data. As pointing output the voltages correspond to the measured position in mrad or mm (mrad or mm / Volt). - Page 9 “Source path” indicates the source path of the installation. “Destination Path”: Here, you can choose the desired destination path. The standard directory is “TEM” in the "ProgramFiles" folder. On Windows Visa or Windows 7 systems, please avoid the "Program Files" folder and choose the path "C:/TEM”! The button “OK, install now!”...

Page 10: Installing Usb Driver
Windows will open the Found New Hardware Wizard. Here, choose to install drivers from a user-specified location. The necessary driver file is located in the directory “TEM/Service/USB Driver” in the Kangoo installation directory (or on the USB Stick). The Hardware Wizard will now finish the installation and no further configuration will be necessary. -
Page 11: Interfacing With A Pc
PSD Reader User Manual 7 Interfacing with a PC The microcontroller of the PSD Reader is accessed via USB using ASCII-formatted text strings. Each string has to be terminated by a carriage return character ( or ASCII 13). ‘\r’ These strings separate into two general categories, namely variables and commands. A variable represents a user-accessible parameter which can be set, queried and stored. - Page 12 PSD Reader User Manual PsdUnitsA 0 t0 3 physical units for displaying the angle PSD 0: ADC units (-32768 to 32767) 1: Volts (-10 to 10) 2: mm @ PSD 3: mrad PsdUnitsB 0 t0 3 physical units for displaying the position PSD...

Page 15: Using The Kangoo Software
The alignment of the parameters of the system is most easily done with the supplied software package Kangoo. Since the PSD Reader is controlled by plain-text commands, it can be configured with any control software like LabView, TestPoint, or other programs written in VisualBasic, VisualC, C++, C#, etc. -

PSD Reader User Manual To save your new settings like gain of the PSD, click on the “VarSave”-Button. The new values will be saved and at the next power cycle or reset, they will be load automatically. To log the beam pointing, please open the section “Recorder”. In the window you can choose some different record options. - Page 19 PSD Reader User Manual In pulsed mode the rising edge of the sum of the PSD is detected and the signal is sampled. There are two different pulsed modes available depending on the repetition rate: If the repetition rate is below 4 kHz, the pulse is sampled twice: One sample at the peak and one sample at idle level.
