KPCI-PIO24 User’s Manual Troubleshooting 5-7
• If, at this point, you’ve tested the OK board in more than one slot on this computer,
continue with step 14.
14. Based on the history of steps 6 through 13, do one of the following:
• If, at any point in this procedure, the OK board was identified as a PCI resource in at least
one slot on the host computer, then any slot in which it did not work is likely defective.
Continue with step 15.
•
If you only had one slot in which to install the OK board, assume that this slot is defective.
Continue with step 15.
• However, if you have installed the OK board in more than one slot and the board has not
been identified as a PCI resource in at least one slot, then the cause of your problem may
be outside the scope of these diagnostics: two or more slots are assumed unlikely to be
defective in the same computer. Read the instructions in “Technical support,” and then
contact Keithley for help in isolating the cause of your problem.
15. Replace the defective slot connector, as follows:
a. Turn OFF the computer.
b. Remove the OK board.
c. Have a qualified service person replace the defective PCI slot connector.
d. Skip to step 27.
16. Continuing from step 8, verify that DriverLINX is installed properly:
• If DriverLINX is installed properly, continue with step 17.
•
If DriverLINX is not installed properly, do the following:
a. Install it now, referring to the DriverLINX installation instructions. Make sure that
DriverLINX installs smoothly and completely.
b. Continue with step 17.
17. Perform I/O bit tests to determine whether you can write and read all I/O bits to and from the
OK board: the I/O loop-back test and the output set test. Perform either or both of these tests,
outlined separately under the headings “I/O loop-back test” and “Output set test.” However,
only the I/O loop-back test is conclusive and is therefore preferred.
18. Based on the results of step 17, do one of the following:
• If you can write and read all I/O bits to and from the OK board, skip to step 21.
• If you cannot write and read all I/O bits to and from the OK board, there may be data
acquisition program errors or defective I/O slot contacts in the slot; continue with step 19.
19. If you cannot write and read all I/O bits to and from the OK board do the following:
• If you have arrived at step 19 before making corrections, there may be data acquisition
program errors; continue with step 20.
• If you have arrived again at step 19 after apparently correcting all program errors in the
data acquisition program, 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.
20. Check if all data acquisition program lines are OK.
Check the program documentation or use a debugger to look for programming errors that
may be causing the problem.
• If no programming errors are found, then some of the slot connector contacts
corresponding to the I/O bits are likely defective, given that the board is known to be OK.
Do the following:
a. Turn OFF the computer.
b. Remove the OK board.
