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 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 Fast Infrared Drivers program diskette.

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.

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 (1 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 2 infrared devices and that the 2 devices are within the 30° cone.
