I/O Connectors

Infrared Port

The infrared port is IrDA 1.1-compliant. 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 allows the transfer of files from one computer to another infrared-

compatible device, without using cable connections. Dell has installed data communications software for you to use with your infrared port. You can

also use other commercially available infrared-capable application programs.

For information on configuring the standard infrared drivers that come with Microsoft®Windows®98, see your operating system documentation.

To install the fast infrared drivers provided by Dell, see the instructions in the readme.doc file on your System Software CD.

If for some reason you need to change the infrared port address, be careful not to create a conflict with the addresses of the serial port or the

parallel port.

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.

Modem Port

The Modem Port option appears only if your computer has an integrated modem. This option allows you to map the address of the port to avoid

address conflicts with other devices.

When this option is set to Customized (the default), the Base I/O address/IRQ is 2F8 IRQ3, the Configuration port is 130, and the 16-bit DMA

channel is DMA 6.

Set Modem Port to Off if you want to disable the port and free its assigned address for another device. When this option is set to Auto, the

operating system or the BIOS configures the port automatically.

USB Connector

Use the USB connector to attach 1 or more USB devices, such as a mouse, to the computer. USB is a peripheral bus standard that enables

automatic detection of USB-compliant peripheral devices.
