BACKGROUND OF THE INVENTION The present invention relates to the connection of an imaging module for connection to an oscilloscope intended to output alphanumeric and semi-graphical messages to an oscilloscope screen for contacting an operator with a device controlled by a microcomputer, respectively. minicomputer.

The prior art wiring solutions for service and measuring devices are not universally sufficient to make the compromise between the imaging unit complexity and sufficient operator awareness as well as the possibility of using one, or more demanding, display unit for multiple types at -riadení. Other previously known solutions, where the samplers without their own display unit connect to the minicomputers equipped with a graphical display are disadvantageous because of the necessity of using, for example, pre-oscilloscopic measurements in addition to the demanding display, and also sophisticated metering circuits that become an essential component of such an economically and economically viable system. -the more challenging the higher the system requirements.

The second branch of the microcomputer is connected to the I / O circuits, which are the first branched output connected to the control unit of the connected device and not visible from the connected device control unit via the branched input and the second branched output of the I / O circuits to the microcontroller. a computer whose third branched output is connected to character memory. The synchronization output and the microprocessor interrupt input are connected to control circuits, the first branched output is connected to the image memory, the second branch output is connected to the multiplexer and the synchronization output is connected to the digital and analog converter, whose branched entry is connected to a microcomputer. The multi-plexer is connected to the oscilloscope control input. The digital-analog converter is connected to the oscilloscope's measurement input.

The connection of the display module for connection to the oscilloscope has the characteristics of a semi-graphical line display, while the function of the oscilloscope used remains fully maintained. The solution is simple, with minimal cost and dimensions. Thus, the connection may be a direct part of the oscilloscope, or a dedicated device, or it may serve as a separate unit for connecting to various device configurations. Other advantages are the versatility, accuracy and increased operator awareness. The connected device control unit can control the display format, the number of lines in the line, the number and spacing of the lines, and it can also get data about the data displayed. The microcomputer of the display module is capable of internally providing various display module functions, such as moving the displayed data screen, selecting a displayable character set, simultaneously displaying data from one area of the image memory to preparing the area data, controlling the inverse display, and the like. The microcomputer of the display module may also partially or completely control the control of the connected device. Furthermore, the possibility of changing the data in the PROM memory 1 means that the shape, type, size and code of the display symbols can be changed.
