I/O Connectors
Infrared Port
The computer comes with an infrared port. An infrared data stream is transmitted through a lens in the computer, up to a distance of 1 m, and received by a compatible
computer, printer, mouse, or remote control.
The infrared port lets you transfer files from the computer to another infrared device, without using cable connections. You can also use other commercially available
infrared-capable application programs.
To use the infrared port, point the computer’s infrared port directly at the infrared port of the compatible device. Infrared devices transmit data in a
30° cone of infrared
light.
Start the data communications software on both devices, and then begin transferring files. Read the documentation that came with your compatible device to make
sure you operate it correctly.
For information on configuring the standard infrared drivers that came with Windows 98, see your operating system documentation.
USB Connector
Use the USB connector to attach up to two USB devices, such as a mouse, to the computer. USB is a peripheral bus standard that enables automatic detection of
USB-compliant peripheral devices.
Pin Assignments for the USB Connector
Serial Connector
Use the 9-pin serial connector to attach a serial device to the computer. The serial port passes data in serial format (one bit at a time over one line). This port supports
a variety of devices, including a serial mouse, that require serial data transmission. If you reconfigure your hardware, you may need pin number and signal information
for the serial connector.
Pin Assignments for the Serial Connector
NOTE: Make sure that there are no books, papers, or other objects between the two infrared devices and that the two devices are within the 30° cone.
