Connect power supply to these pins.
(4) AIN_YP, AIN_XP (RCA Jack)
Analog signal input Jack; When the touch panel is not connected, it can be evaluated by input 0V~VDD signal
directly to the XP pin and the YP pin.
(5) LED9,10 (WHITE LED)
LED is lit by the PWM signal for controlling the brightness from AK4184A.
(6) PORT1 (25 pin D-sub)
Control port; Please connect it with PC with D-sub parallel cable.
