1-10 Chapter 1: Product Overview
Hardware Monitor
The hardware monitor generates an interrupt to the system whenever
any of the internal voltages used by the system processor goes above or
below the acceptable operating range. An interrupt is also generated
when the temperature of the Processor exceeds safe levels. Software
can use this indication to slow or stop the system and/or force a reset.
Mini PCI Expansion Header
A single Mini PCI expansion header is provided to support optional
features.
IDE Header
A standard IDE header is provided to support the 3.5-inch hard disk
drive.
Touch Screen Controller
The MicroTouch “Excalibur” chip is used to interface the touch panel.
This controller supports MicroTouch resistive and capacitive panels.
In order to save an RS-232 port, the touch data is delivered to the
system through the mouse interface. This requires a mouse-aware
touch device driver for the appropriate OS.
When the system is operating in the dimmed display mode, touch
activity can restore full brightness if instructed by software to do so.
When system is in low power mode, touch activity can generate the
mouse port interrupt (IRQ12).
