C-14 Systematic Problem Isolation KPCI-3110 and KPCI-3116 User’s Manual
2. Based on the results of step 1 , 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 “ Problem isolation Scheme G: verification of problem solution .”
•
If all external I/O connections are found to be normal, then, by process of elimination,
the KPCI-3110 or KPCI-3116 board(s) originally installed in the computer is likely the
cause of the problem. Continue with “
Problem isolation Scheme F: the board .”
Problem isolation Scheme F: the board
In Scheme F, after having eliminated other problem causes, you assume that KPCI-3110 or
KPCI-3116 hardware malfunctions are at fault. If only one KPCI-3110 or KPCI-3116 board was
installed, you replace or repair it. If more than one KPCI-3110 or KPCI-3116 board was
installed, you use PCI connection tests, and if necessary I/O tests, to find which board is bad.
NOTE This is not a stand-alone procedure. Use it only when it is called for by
another procedure.
Problem isolation Scheme G: verification of problem solution
In Scheme G, you put your system back together and verify that it works, after apparently
resolving the problem in prior schemes.
NOTE
This is not a stand-alone procedure. Use it only when it is called for by
another procedure.
Follow these instructions as you perform Scheme G:
1. Assuming that the problem has been resolved, do the following:
a. Turn off the computer.
b. Install good KPCI-3110 or KPCI-3116 boards in good slots.
c. Reconnect all external circuits. If you left external circuits connected to the screw termi-
nal accessory, connect the accessory to your board. If you disconnected external circuits
from the screw terminal accessory, reconnect them and the accessory as discussed in
Section 3 , “ Installation and Configuration .”
d. Turn on the computer and start your data acquisition software.
2. Repeat the task that you were doing with your data acquisition system when the problem
occurred, and observe the performance.
3. Based on the results of step 2 , 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
Section 6 , “ Technical sup-
port ,” and then contact Keithley for help in isolating the cause of your problem.
