C-12 Systematic Problem Isolation KPCI-3101 — KPCI-3104 Series User’s Manual• If all three of the following apply, then assume that you do not need to repeat the analogoutput software test. However, by process of elimination, you failed the digital I/O soft-ware test the last time you tried. Go to step 5 and repeat the digital I/O software test.– Your board has analog outputs.– You have done the analog output software test at least once.– Your software passed the analog output software test the last time you tried.• If your board does not have analog outputs then by process of elimination, you failed thedigital I/O software test the last time you tried. Go to step 5 and repeat the digital I/Osoftware test.13. You arrived at this point from step 8, because presumably you have a commercial or other-wise unmodifiable applications program that is assumed to be proven. Contact the maker ofyour software to determine whether you have a version designed to work with theKPCI-311–4 version of DriverLINX. For example, not all versions of TestPoint will workwith KPCI-3101–4 DriverLINX. Also, check whether the program is installed correctly.14. Select your next step in Scheme C based on the criteria given in the following alternatives:• If you are certain at this point that your application program is the correct version AND isproperly installed, then the cause of your problem may be outside the scope of thesediagnostics. Read the instructions in Section 6 “Technical support” and then contactKeithley for help in isolating the cause of your problem. Also, contact Keithley if youhave been unable to find out elsewhere whether you have the correct version of software.• If you are uncertain at this point that your application program is properly installed, thenreinstall it now. When you are satisfied that it is properly installed, go to step 11 and retryselected I/O software tests.Problem isolation Scheme D: expansion slot connectorsIn Scheme D, you further check and try to remedy apparent expansion slot malfunctions.NOTE This is not a stand-alone procedure. Use it only when it is called for byanother procedure.1. Remove computer power again, and install a KPCI-3101–4 board that you know is func-tional. Do not make any I/O connections.2. Turn computer power on and check operation with the functional board in place. This testchecks the computer accessory slot. If you were using more than one board when the prob-lem occurred, use the functional board to also test the other slot.3. If the accessory slots are functional, use the functional board to check the I/O connections.Reconnect and check the operation of the I/O connections, one at a time.4. If operation fails for an I/O connection, check the individual inputs one at a time for shortsand opens.5. If operation remains normal to this point, the problem is in the KPCI-3101–4 board(s) origi-nally in the computer. If you were using more than one board, try each board one at a time inthe computer to determine which is faulty.
