I/O bit tests

a. If an original board remains installed following step 25, then skip to step 26e.
b. Turn OFF the computer.
c. Install one of the original boards in a slot known to be satisfactory.
d. Turn ON the computer.
e. Perform the I/O tests outlined in the "I/O bit tests" section. Then return to this step (26e).
f. Based on the results of step 26e, do one of the following:
•
If, in step 26e, you cannot write and read all I/O bits to and from the board, 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 25e, you can write and read all I/O bits to and from the board, repeat steps
25b through 25e for each board until you find a faulty board. Replace the faulty board
with the OK board. (To repair the faulty board or obtain a new one, contact Keithley
as described in "Technical support.") Then continue with step 27.
•
However, if you have reached this point after trying all boards, and the I/O on each
board has been found satisfactory, then the cause of your problem may be outside the
scope of these diagnostics. Read the instructions in "Technical support," and then
contact Keithley for help in isolating the cause of your problem.
27. Assuming the problem has been resolved, do the following:
a. Turn OFF the computer.
b. Install the good KPCI-PIO96 boards in good slots.
c. Reconnect all external circuits as discussed in Section 3, "Installation."
d. Turn ON the computer.
e. Verify that the system now performs satisfactorily.
28. Based on the results of step 27e, do one of the following:
•
If the system now performs satisfactorily, you have successfully isolated and corrected
the problem.
•
If the system still does not perform satisfactorily, then the cause of your problem may be
outside the scope of these diagnostics. Read the instructions in "Technical support," and
then contact Keithley for help in isolating the cause of your problem.
a. Reinstall the board and reconnect external circuits as discussed in
Section 3, "Installation."
b. Reevaluate the integrated system. If the system works, you have isolated the problem;
end the procedure now.
c. However, if the system still does not work, then there must be other issues. If you have
another KCPI-96 board that you know is functional, then proceed to step 5. If you do
not have another KCPI-96 board that you know is functional, then call Keithley for
technical support.
The I/O bit tests check whether the input and output functions of the board are operating properly.
They also act as a backup tests for a defective slot connector. Of the two tests outlined below,
only the I/O loop-back test is conclusive and is therefore preferred.
These tests are intended to be used when requested in the "General problem isolation procedure."
However, they may also be used for general performance checks.
