Mouse Port
The supports two mouse ports. The external mouse port is routed to the
PS/2 mouse connector; the internal mouse port is routed to the touch screen
controller. If touch screen drivers are loaded, the external mouse port is disabled.
Both the external port and the touch screen controller may be plugged in at the same
time. However, the driver loaded may impair the operation of one of the ports. If the
Microtouch mouse drivers are loaded, the external mouse port will use these drivers.
Note
When using the Xycom touchscreen controller (PIN 140554), the
will behave the same. If using a PS/2 mouse is desired, install
the Touch-Base touch driver in serial mode. In serial mode, the
controller will use a COM port and free the PS/2 mouse port. Please
follow the installation instructions on the Xycom documentation.
A polyswitch protects the +5 V on the mouse port. This device opens if the +5 V is
shorted to GND. Once you remove the shorting condition, the polyswitch allows
current flow to resume.
IR Interface
The IR interface, which uses UART2, is a half-duplex serial port capable of 115
Kbaud transfer rates. It also supports two transfer formats: IrDA and ASKIR. You
must load software to support communication between two devices.
Flat-panel Interfaces
The incorporates two flat-panel connectors. The STN connector interfaces
directly to STN flat panels. It provides a substrate voltage (VEE) of 34 volts, contrast
control, and frame rate modulation to allow 4096 colors to be displayed. The TFT
connector interfaces directly to TFT flat panels.
The flat-panel type is jumper selectable. Refer to Chapter 2 for jumper settings.
Floppy and Hard Drives
The can interface to a floppy drive via the external floppy connector. To
connect a floppy drive to the external connector after power up, you must specify the
floppy drive as a 1.44 Mbyte drive, and disable the floppy check option in the BIOS
setup menus. If this is not done, the system will generate a floppy drive error during
the Power On Self Test (POST).
The PCI-to-IDE interface supports one hard drive via the on-board IDE controller.
Caution
The total IDE cable length must not exceed 18 inches.
