If the customer cannot establish a connection between the
ThinkPad 701C/701CS and a remote system, perform the
following steps:
1. Ensure that the device the customer attempted to
connect with is an Infrared Data Association (IRDA)
compliant device.
2. Check to make sure that both systems are using the
same revision level of the same software.
3. Check setup options on both systems to ensure that
the baud rate and other setup parameters are the
same.
4. Check the Configuration Utility to ensure that the
infrared transceiver is assigned to the same serial
port that is designated in the application software and
that the IRQ assignment is not shared with any other
device such as the internal modem or external serial
port on the MultiPort II.
5. Verify that the two systems are in close proximity
(less than 1 meter [3.2 feet] apart for IRDA-compliant
devices) and that the infrared transceiver window on
the ThinkPad 701C/701CS is aligned with (directly
opposite) the remote device’s window.
6. Ensure that the windows on both systems are clean
and unobstructed.
If the two systems still will not connect after you have
followed the preceding steps and the remote system is
another computer with a terminal program (for example,
Windows** Terminal** or Procomm**) installed, perform the
following tests:
1. Set up the terminal application on each system to
communicate with the infrared transceiver serial port
at a speed of 115KB per second.
2. Type characters on the ThinkPad 701C/701CS
keyboard and check to see whether or not these
characters appear on the remote system. (Note that
the characters you type will not appear on the
ThinkPad 701C/701CS system.)
3. Type characters on the remote keyboard and check
to see whether or not these characters appear on the
ThinkPad 701C/701CS system.
4. If characters do not appear in either step 2 or 3 and
you are certain that infrared is working correctly on
the remote system, replace the inverter card.
5. If characters do appear, consult the software vendor
to ensure that the customer is using a compatible
software package and that the setup parameters are
correct.
