Introduction

Your new DM8112CX solid state data display is a precision engineered product designed for use with the computer system which outputs a composite video signal. This picture tube employs an implosion proof, green phosphor. This data display is equipped with DC restoration (In the absence of a data signal, the data display screen will be fully black: no raster). Solid state electronics used in the DM8112CX provides improved reliability and superior performance even in continuous duty applications.

Controls

  • POWER SWITCH (ON-OFF): Rocker switch for power control. Push side with red dot for "ON," opposite side for "OFF."
  • POWER INDICATOR: Red lamp lights up when power switch is turned on.
  • BRIGHTNESS: Adjusts display brightness.
