The programmable encoder that is presented in this paper realizes the coding in many variances in order not to permit the code breakage by an unauthorized person. This paper presents an electronic circuit that identifies a code introduced using a keyboard, if this code is corresponding to the stored code, the system actuates an electromagnetic device. If the input code does not correspond to the stored one, the system blocks the inputs. The electronic circuit is realized in LabVIEW and permits an analogical command to the electromagnetic device using a data acquisition board.
