With the software LDMTool all laser distance sensors of the LDM series which have a serial interface can comfortably be parameterized from the PC. A simple user interface displays all available parameters of the currently connected sensor and all currently measured values as well as the state of the different output signals. A terminal window has been implemented for direct communication. Besides that, with the full version of the LDMTool a recording function (Log Window) and a graphical display (distance-time diagram) are available.
