Communication Devices
Infrared signals are sent through an invisible beam of infrared
light and require an unobstructed line of sight path.
Linking to an infrared device
The infrared port supports both low-speed connections of up to
115 kilobits per second (Kbps) and high-speed connections of up
to 4 Mbps. Infrared performance may vary depending on the
performance of infrared peripherals, distance between infrared
devices, and applications used.
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 one
another at a distance no greater than 1 meter (3.3 feet).
Position the ports so that they face one another directly.
Because the maximum capture angle is 30 degrees, the ports
must be aligned no more than 15 degrees off-center.
