c. Have a qualified service person replace the defective PCI slot connector.
d. Skip to step 27.
•
If programming errors are found, do the following:
a. Debug and fix all known data acquisition program errors.
b. Repeat steps 17 and 18.
21. Continuing from steps 17 and 18, if you can write and read all I/O bits to and from the OK
board, do the following:
• If you have arrived at step 21 after program corrections have been made, and you can now
write and read all I/O bits to and from the OK board, then the problem has apparently been
resolved. Skip to step 27.
• If you have arrived at step 21 without making data acquisition program corrections and
can write and read all I/O bits to and from the OK board, then faulty external I/O
connections may have caused your problem. Continue with step 22.
22. Check each external I/O connection, one at a time, for short circuits and open circuits. If
KPCI-PIO96 boards were installed in more than one PCI slot, check the I/O connections for
all boards.
23. Based on the results of step 22, do the following:
• If any external I/O connections are found to be faulty, assume that the problem was caused
by the faulty connections, then proceed as follows:
a. Correct the faulty external connections.
b. Skip to step 27.
• If all external I/O connections are found to be normal, then, by process of elimination, the
KPCI-PIO96 board(s) originally installed in the computer is likely the cause of the
problem. Continue with step 24.
24. Replace the faulty board. Do one of the following:
•
If only one KPCI-PIO96 board was installed when the problem occurred, proceed
as follows:
a. Leave the OK board in the expansion slot as a replacement. To repair or replace the
faulty board, contact Keithley as described in "Technical support."
b. Skip to step 27.
• If more than one board was installed when the problem occurred, determine which one is
faulty, starting with step 25.
25. Check if one of the original boards is not detected as a PCI resource. Proceed as follows
a. Turn OFF the computer.
b. Remove the OK board.
c. Install one of the original boards in a slot known to be satisfactory.
d. Turn ON the computer and, during boot, determine whether your operating system has
identified the board as a PCI resource. See step 6 for more information.
e. Based on the results of step 25d, do one of the following:
• If, in step 25d, the board is not recognized as a PCI resource, you have located the
faulty board; replace it with the OK board. (To repair the faulty board or obtain a new
one, contact Keithley as described in "Technical support.") Then skip to step 27.
• If, in step 25d, the board is recognized as a PCI resource, repeat steps 25a through 25e
for each board. If you have reached this point after trying multiple boards, and each
board has been recognized as a PCI resource, then continue with step 26.
26. Determine which board has faulty I/O. If the faulty board survived the PCI resource test in
step 25, it should fail the I/O test.
