Troubleshooting
Table 2-13
Solving Infrared
Problems
Problem
Possible Cause
Solution
Cannot communicate with
another computer
.
The appropriate software is not
running on both computers.
Install the appropriate software on the
second device, start the second
device, and start the program on both
computers.
The other computer does not have
an IrDA-compliant infrared port.
Your Compaq computer uses the
IrDA communications protocol.
Communication between infrared
devices must use the same
communications protocol. Check the
manufacturer±s instructions for
connecting with infrared devices or try
connecting with a device you know to
be IrDA-compliant.
The pathway between the infrared
ports is obstructed, one port is
more than 30 degrees (plus or
minus 15 degrees off the center
line) from the other, or the ports
are more than one meter apart.
Remove the obstruction, align the
infrared ports to within 30 degrees,
and position computers within 1.5
feet (about 0.5 meter) of each other.
There is an interrupt request (IRQ)
conflict.
Check for IRQ conflicts in the Device
Manager
If two devices have the
same IRQ address, reassign one of
the devices.
There is a baud rate conflict.
Select the same baud rate for both
computers.
There is a conflict with the # bits.
Select the same # bits setting for both
computers.
There is a stop byte conflict.
Select the same stop byte for both
computers.
There is a parity conflict.
Select the same parity setting for both
computers.
Cannot transmit data.
Direct sunlight, fluorescent light,
or flashing incandescent light is
close to the infrared connections.
Remove the interfering light source(s).
There is interference from other
wireless devices.
Keep remote control units such as
wireless headphones and other audio
devices away from the infrared
connections.
There is a physical obstruction in
the way.
Do not place objects that will interfere
with a line-of-sight data transmission
between the two units.
One of the units was moved
during data transmission.
Do not move either unit during data
transmission.
The orientation of the units is
wrong.
Adjust the devices so that they point
directly at each other.
The distance between the units is
too great.
Verify that devices are not more than
1.5 feet (0.5 meter) apart.
