BNC/D-sub signal auto-selection circuit

摘要

A circuit for automatically selecting between the BNC or the D-SUB includes a detector for discriminating a signal currently being input by D-SUB or BNC synchronizing signals input from a computer system. Responsive to a control signal input from the detector, a D-SUB/BNC selecting integrated circuit for generating a predetermined operating signal to either a D-SUB driving circuit or BNC driving circuit.
