HX Board
Figure 14
PC RGB Signals are input to the HX Board. The RGB signals as well as the
vertical and horizontal sync signals are amplified by a series of transistor
amplifiers. The RS232C communications bus line is also connected on this
board. The RS-232C connection is provided so that operation changes can be
made via PC. An example of an application of this port would be remote turn on
of the unit for a kiosk or similar display.
The outputs of the HX board are applied to the D1 board via connector HX1/D3.
