Ports and Connectors: Dell Inspiron 3800 System Reference

Serial Port Connector

To attach a serial device to the computer, use the 9-pin serial port connector.
The serial port passes data in serial format (one bit at a time over one line). This port supports
a variety of devices that require serial data transmission, including a serial mouse, serial
printer, plotter, or external modem.

AC Power Connector

Use the AC power connector to attach the
converts AC power to the DC power required by the computer.
You can connect the AC adapter with your computer either turned on or off.
The AC adapter works with electrical outlets worldwide. However, power connectors vary
among countries. Before using AC power in a foreign country, you may need to obtain a new
power cable designed for use in that country.

Infrared Port

The computer's infrared (IR) port is compatible with Infrared Data Association (IrDA) 1.1 (Fast
IR) and 1.0 (Slow IR) standards. An infrared port lets you transfer files from your computer to
another infrared-compatible device without using cable connections. An infrared data stream is
transmitted through a lens in the computer up to a distance of 1 meter (m) (3.3 feet [ft]). This
light is received by a compatible computer, printer, mouse, or remote control.
The default address of the infrared port is COM3. To avoid resource conflicts with other
devices, remap the address of the infrared port.
When the computer is being used with the APR docking solution, the infrared port on the
computer is automatically disabled.
Point the computer's infrared port directly at the compatible device's infrared port. Infrared
devices transmit data in a 30-degree cone of infrared light. Start the data communications
software on both devices, and then begin to transfer files. Read the documentation that came
with your compatible device to make sure that you operate it correctly.
