Diagnostic LEDs
Following is a description of the LEDs and what it means when they're lit:
Power
Lit when the system has power
Disk
Lit when the computer is accessing the disk drive
COM
Lit when there is communication activity on one of the serial ports,
including communication between the computer module and the
touchscreen (if on COM2) or a serial mouse.
Input
Lit when the unit has a touchscreen (LED gets brighter when a
touch input is detected) or a key is pressed
During power-up, firmware on the processor board checks the hardware
configuration against the configuration stored in the CMOS memory.
IR (Infrared)
The IR port transceiver is located behind this window. The IR port is IrDA
and ASKIR compliant. You can connect the unit to any IrDA compatible
device. You must load special software (not included) to use this feature.
The infrared (IR) link is designed to operate at a distance of 0 to 1 meter.
Enable the interface through the BIOS setup menu.
Note
: When the IR
port is chosen in the system BIOS, COM2 is not available.
