ISA/IDE Backplane Connector (ATIDE1)
The ISA/IDE Backplane connector is a 120-pin connector. This connector provides
both ISA and IDE signals to the backplane.
IDE Connector (HDD1)
IDE hard drive connector is a 40-pin header. This header is intended for future op-
tions and testing.
Power Connector (PWR1)
This 20-pin connector is a standard ATX style PC power supply connector.
Touch Control Connector (TCTRL1)
This 40-pin connector supports 5-wire and 4-wire touchscreens. The connector is
latching to provide for a DRAM SIMM type installation.
Touch Connector (TCH1)
The five-pin touch connector is the interface to the touch panel.
Flat Panel Connector (FPNL1 and FPNL2)
The flat panel connector is a 60pin SMD through board connector. The four flat
panel select lines define up to 16 unique panel types. If all signals are high (no cable
attached) the system defaults to CRT.
The system board su5V and 3.3V TFT panels with a custom flat cable. It
supports STN panels with a 2.5” X 2.75” PCB which contains the DC/DC for the
custom VEE voltage along with the contrast and power sequencing circuit. There are
also provisions to support a temperature sensor for automatic contrast control.
Backlight Inverter Connector (DCINV1)
This 8-pin connector provides power for the backlight inverter.
