4.4 VGA interface

The panel PC's AGP VGA interface can drive conventional CRT dis-

plays. It is also capable of driving a wide range of flat panel displays,

including electroluminescent (EL), gas plasma, passive LCD and active

LCD displays.

The panel PC's AGP SVGA interface supports 5 V and 3.3 V LCD dis-

plays. The LCD cable already has a built-in default setting. You do not

need to adjust any jumper or switch to select the panel power.

An onboard watchdog timer reduces the chance of disruptions which

EMP (electromagnetic pulse) interference can cause. This is an invalu-

able protective device for standalone or unmanned applications. Setup

involves one jumper and running the control software. (Refer to Appen-

dix B.)

When the watchdog timer activates (i.e. CPU processing has come to a

halt), it can reset the system or generate an interrupt on IRQ11. This can

be set via jumper J4 as shown below:
