Installation

NOTE !

The installation of the USB-driver and the control software requires administrator privileges.

Please uninstall any previously installed DigiLock software. Otherwise the installations may interfere.

USB-Driver

The DigiLock 110 provides a USB connection to load the firmware and to control the module via the supplied PC based software. In order to communicate with the DigiLock 110, the USB driver has to be installed before the installation of the application software. The driver is located in the directory �Drivers\USB� on the installation CD supplied with the DigiLock 110 module. Run the .exe file to install the driver on the PC.

After the driver is installed successfully, connect the DigiLock 110 module to the PC with the appropriate USB cable. The operating system will recognize the new hardware.

Control Software

Start the program �setup.exe� in the folder �Installer� on the CD that is shipped together with the DigiLock 110. The installer will guide you through the installation process.

 

Changes

Version 1.8.1

      Update of user manual.

 

Version 1.6.0

         AutoLock and PID controller: Function of window option changed. The parameters �Min� and �Max� are replaced by the more versatile set of parameters �Level out Max�, �Level out Min�, �Level in Max� and �Level in Min�.

 

Version 1.5.4.70

         Renaming and repositioning of several front panel elements

         Profile and calibration data divided in two separate files

 

Version 1.1.3.40

         Tab with manual options for PID controllers is no longer present in AutoLock mode when the �Advanced Settings� option is selected

         MinMax Intense option was renamed to Lock Window

         Frequency Analysis: the averaging algorithm now works with frequency spectra averaging not any longer with averaging the time signals and performing the FFT afterwards

 

Version 1.0.2.19

         Files containing device specific module settings are no longer stored in the installation folder. They can be found in ...\Documents and Settings\<User Name>\Application Data\Toptica\DigiLock\ (English Windows version) or ...\Dokumente und Einstellungen\<User Name>\Anwendungsdaten\Toptica\DigiLock (German Windows version)

 

What�s New

Version 1.8.0

         Mouse wheel support for controls added.

         LabVIEW 2013 SP1 f6-Patch integrated.

 

Version 1.6.0

         Speed of Remote Control Interface improved significantly

         Response: Reference tracks of graph are saved to disk, too

         System Startup: Software automatically determines the state of the DigiLock hardware. Unnecessary resets and firmware uploads are eliminated

         Frontend settings are stored on the module

         PID Controllers: Various controller states are sampled continuously

         PID Controllers: Relock amplitude for the channels SC110 out and DCC Iset is increased to the full scale of the analog output

         PID Controllers: Software option for interrupting the PID controller action (hold function)

         Simulation: Signal chain components can be included selectively into transfer function simulation

         LI/PDH: demodulated signal can be output on AIO1out

         Several bugfixes

 

Version 1.5.4.70

         Multi-Module Support: up to 4 DigiLock modules can be operated on one computer

         DigiLock Module Server (DMS): administration of all connected DigiLock modules

         Remote Control Interface: the GUI and DMS can be controlled via TCP commands

         Remote Control Interface: full set of LabVIEW VIs is provided for easy integration of the DigiLock in user applications

         PID Controllers: reset option with variable reset rates

         PID Controllers: relock performance improved when PID controller operates with high derivative gain

         Scope/Spectrum: configurable smoothing function

         Spectrum: option to suppress the DC level

         AutoLock Mode: more detailed locking options

         AutoLock Mode/Display: more versatile selection of lock point in the graph

         AutoLock Mode/PID Controllers: reset option when input signal is out of supervision window

         LI / PDH: automatic phase adjustment

 

Version 1.1.3.40

         AutoLock Mode: when switching off the AutoLock and both PID controllers are involved the controllers are switched off simultaneously not with a time delay of several milliseconds

         PID Controllers: the behavior of the controller when switching off the lock (keep PID value or reset PID) can be configured for both controllers

         PID Controllers: the input channel selection of the controllers is supervised. This prevents from choosing the wrong input in case of top of fringe stabilization (LI, PDH)

         PID Controllers: the delay time for the relock procedure is configurable

         Scope / Frequency Analysis: PID 1 out and PID 2 out implemented as display traces

 

Version 1.0.2.19

         Software can be operated on non-administrator computer accounts

         AutoLock Mode: automatic adaptation of the timescale to the scanning frequency. The �Timescale� control is no longer available

         AutoLock Mode: automatic tracking of the selected lockpoint

         AutoLock Mode: LI- or PDH-error signal is displayed in the graph

         AutoLock: relock options can be modified during the relock procedure

         Scope / Frequency Analysis: overload indicators are turned on if the observed signals reach its limits

         Scope / Frequency Analysis: new signal available: error

         Scope / AutoLock / Frequency Analysis: display of mean- and rms-value for both channels

         Network Analyzer: the measurement can be stopped during acquisition

         LI / PDH: offset for the error output can be set

         Loading user profiles with options

         PID Controllers: the output can be limited

         PID Controllers: during manual operation each controller has its own set of MinMax Intense and Relock parameters

         PID Controllers: when using the MinMax Intense option the actual state (if the selected channel is within its limits) can be monitored on the digital IO line
