4.5.1 LCD panel power setting
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.
4.5.2 Panel type select (SW1)
SW1 is a 8-pin dip switch for selecting panel type and display mode. A
1024 x 768 TFT LCD is used in the PPC-S154T, so the switch is preset
according to the table below. The switch is already defaulted for the PPC-
S154T's LCD, so it should not be modified. If you require modification
for a special purpose, we recommend that you consult your distributor or
our sales repreentative for detailed information.
4.6 Watchdog Timer Configuration
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. When the watch-
dog timer activates (i.e. CPU processing has come to a halt), it can reset
the system. (Refer to Appendix A.)
