PCMCIA Cards and Expansion Sockets Chapter Two - System Features

The following table briefly describes each of the IR modes available. You must set
these modes in BIOS. Please refer to ”Chapter Three - Running BIOS Setup” for
information on the BIOS Setup program.
Follow the guidelines listed below when using the infrared communication module
to transmit or receive data.
•
Make sure the infrared communication field in the BIOS Setup program is
set to FIR. Refer to ”Chapter Three - Running BIOS Setup.”
•
Ensure that the TREK 2’s FIR module is properly lined up with the other
device’s infrared communication module. The angle between the two
Infrared Communication modules should not exceed ±15°.
•
There should be a clear, unobstructed path between the two infrared
communication modules; otherwise the optical signal will be blocked.
Likewise, do not place anything between the two infrared communication
modules during data transmission.
•
Make sure the distance between the TREK 2’s FIR module and the other
device’s infrared communication module does not exceed one meter.
•
Do not move either the TREK 2 or the other device during transmission of
data, otherwise data transmission will be distorted resulting in loss of data
or a system crash.
•
An error can occur if FIR transmission is conducted in an environment with
high levels of noise. To avoid transmission errors do not transmit infrared
communication signals near equipment with compressors, such as
refrigerators or air conditioners.
PCMCIA Cards and
Expansion Sockets
The TREK 2 features two PCMCIA (Personal Computer Memory Card
International Association) expansion sockets designed to interface with one or two
Type II cards, or one Type III card. This sophisticated innovation allows you to
expand and customize your computer to meet a wide range of computing needs
without sacrificing portability. PC cards accommodate a number of expansion
options. Memory cards, modems, hard disks, and network adapters are just a
small sample of the PC card products available on today’s market.
