Where the objects to be controlled have intricate shapes and textures, the incidence of mirror component of the reflected radiation to the receiving window should be minimized. © 2018 Schmitt Industries Revision 1.1... -
Page 8: Connection
Intensity of the reflected radiation depends on the surface characteristics of the object under control. Therefore, the output power of the laser and the time of integration of radiation incident onto the CMOS-array are automatically adjusted to achieve the maximum measurement accuracy. © 2018 Schmitt Industries Revision 1.1... -

The communications protocol is formed by communication sessions, which are only initiated by the ‘master’ (PC, controller). There are two kinds of sessions with such structures: 1) “request”, [“message”] — [“answer”], square brackets include optional elements. 2) “request” — “data stream” — [“request”]. © 2018 Schmitt Industries Revision 1.1... -
