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.
For more information about using an infrared device, see the documentation that came with your operating system. The Microsoft Windows NT 4.0
operating system does not support the use of infrared devices.
NOTES: Make sure that no books, papers, or other objects come between the two infrared devices and that the two
devices are within the 30-degree cone.
If the infrared device does not work, the computer and device may be misaligned. Move the device and computer to bring
them into the 30-degree cone.
