Configuring the Infrared Port
If you are using optional infrared software and a preinstalled
operating system, the following information may be helpful.
■ The infrared port default settings are:
❏ DMA = 1
❏ I/O addresses = 3E8-3EFh
❏ IRQ = 3
■ The optimal port selection in Direct Cable Connection is
Infrared Port.
Setting Up an Infrared Transmission
For information about using infrared software, refer to your
operating system Help file.
To set up infrared devices for optimal transmission:
■ Prepare the infrared ports on both devices for transmission.
■ Position the devices so that their infrared ports face each
other at a distance no greater than 3.3 feet (1 meter).
■ Position the ports so that they face each other directly.
Because the maximum capture angle is 30 degrees, the ports
must be aligned no more than 15 degrees off center.
■ Shield the ports from direct sunlight, flashing incandescent
light, and energy-saving fluorescent light.
■ Be sure that no signals from remote control or other wireless
devices, such as headphones or audio devices, aim at a port.
■ During the transmission, do not move either device and do
not allow objects or movement to disrupt the beam.
