Abstract: The invention relates to a method for configuring sensors by transferring configuration data containing an existing configuration of a sensor from an original sensor to a sensor to be configured, comprising the steps of:
connecting the original sensor in its configured state to a module which stores the current configuration data of the original sensor and a checksum corresponding to the configuration data in the module;
connecting the module to the sensor to be configured;
reading the configuration data stored in the module into the sensor to be configured;
calculating a new checksum corresponding to the data read in;
then comparing the calculated checksum with the checksum stored in the module; and
generating an error message in the event of a non-match of the two checksums.
Abstract: The invention relates to a device for locating objects penetrating into a region of space to be monitored, having a housing (1) which contains a transmitter (3) and a receiver (4) for optical radiation as well as a rotatable optical deflecting device (8) with, on the one hand, a transmitting deflecting mirror (11), which can be rotated about a rotation axis (10) and is inclined with respect to the latter for a beam (5) emerging through a window (2) in the housing (1) into the region of space to be swept by the emerging beam (5) and, on the other hand, with a receiving deflecting mirror (12) for directing a beam (16), reflected from the region of space and incident through the window (2), to the receiver (4).
