A control signal generator of the VME bus system

摘要

The present invention relates to a control device for controlling a high voltage (Eb) part of a deflection device and a DY switching part of a device for checking the reference of a CRT display in a deflection device used in an ITC semi-automatic system, The present invention relates to a control signal generator for a VMC bus system for controlling a deflection device. More particularly, the present invention relates to a control signal generator for a VMC bus system, A switching means for switching the control signal generating means, filtering means for inputting / outputting data by a control signal of the control signal means, filtering means for filtering / D / A conversion means for converting a digital signal inputted from the means into an analog signal, Power control means for matching the ground terminal of the D / A conversion means with the ground terminal of the deflection device, respective switching means for holding the control signal and the data signal output from the control signal generation means and the filtering means, Means for selecting a board signal to be inputted from a computer in accordance with an address signal designated by a dip switch; A3 to A5) signal to select an IC and generate a chip selection (CS) signal, a deet signal generating means for generating a de-tec signal by delaying a system clock according to a board selection signal by a desired amount, Read / write means for making the data into 16 bits by means of the DS0 and DS1 signals to read and write data, DS0 and DS1 signals for managing data, Re-combined "low" and having an activation means for outputting a signal produced by mixing the cathode-ray tube, such as 14 ", 20", 21 "is to improve the productivity of cathode-ray tube.
