IR Wireless Communication
The Notebook PC is equipped with an Infrared (IR) Communication Port located on the rear side. The IR port comes with
IrDA Serial Infrared Data Link Version 1.1 compliance, which allows you to perform point-to-point wireless communica-
tions. You can use a SIR/FIR-specified application to transmit or receive data files with other systems equipped with an
infrared port. The following table briefly describes each of the IR modes available. You must set these modes in the BIOS
before you start to install the IR driver and file-transferring applications. FIR (Fast Infrared) supports up to 4Mbps and
SIR (Serial Infrared) supports up to 115.2Kbps
Guidelines for using IR communication
Follow the guidelines listed below when using the Infrared Communication :
• Make sure the IR Mode in the BIOS Setup is properly set to the mode you would like to use.
• The angle between two Infrared Communication Ports should not exceed (±15˚).
• Make sure the distance between the Notebook PC’s IR and target device IR does not exceed 40 inches (1 m).
• Do not move either the Notebook PC or the other device during transmission of data.
• An error may occur if IR transmission is conducted in an environment with high levels of noise or vibration.
Universal Serial Bus Port
USB (Universal Serial Bus) is a peripheral bus standard developed by PC and telecom industry leaders that will bring
plug and play of computer peripherals outside the system, eliminating the need to install internal expansion cards and
drivers.
The Notebook PC is equipped with one USB port, which uses a shielded receptacle connector. This allows computer
peripherals to be automatically configured as soon as they are physically attached, without the need to reboot or run
setup. USB will also allow up to 127 multiple devices to run simultaneously on a single computer, with peripherals such
as monitors and keyboards acting as additional plug-in sites, or hubs.
The Notebook PC’s built-in USB host controller initiates data transfer at a full-speed of 12Mbps for digital cameras and
a low-speed of 1.5Mbps for keyboards and mice. The host also manages the logical connection of devices.
Driver Support
The Windows 98 operating system comes already equipped with a standard driver that allows your Notebook PC to
recognize USB peripherals. However, new peripheral products may need software driver upgrades. Contact an autho-
rized dealer for more information.
