Communicating with the Infrared Port
Considerations for Communication
Consider the following when communicating with the infrared port:
When communicating between the infrared port and an infrared
port on another computer, the infrared ports on the computers
must face each other directly at a communicating distance.
You need to run the same communication application on both
computers to communicate between your computer and another
computer device. Refer to the application manuals for more
information.
Run only one communication application for the infrared port at a
time.
The communicating distance might need to be less if:
– The other system is not the same model as your computer.
– There is interference from ambient light. It is recommended
that you do not use infrared communication in bright
sunshine. Light from a certain type of fluorescent lamps can
also interfere with communication.
– The infrared port is not directly facing the other
communicating port.
Headphones or audio-visual devices that use infrared may
interfere with your communication. You might hear noise through
the headphones, or the computer might not be able to
communicate with other devices through the infrared port.
