This "software driver" implements the communication protocol for interfacing a SICK LMS2XX laser scanners through a custom USB RS-422 interface board.
NOTE that this class is for a custom hardware built at our lab (MAPIR, University of Malaga). For a generic serial interface, see the class CSickLaserSerial.
This class does not need to be bind, i.e. you do not need to call C2DRangeFinderAbstract::bindIO. However, calling it will have not effect. In this class the "bind" is ignored since it is designed for USB connections only, thus it internally generate the required object for simplicity of use. The serial number of the USB device is used to open it on the first call to "doProcess", thus you must call "loadConfig" before this, or manually call "setDeviceSerialNumber". The default serial number is "LASER001"
Warning: Avoid defining an object of this class in a global scope if you want to catch all potential exceptions during the constructors (like USB interface DLL not found, etc...)
