KPCI-3110 and KPCI-3116 User’s Manual Systematic Problem Isolation C-13
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 is
properly installed, then the cause of your problem may be outside the scope of these
diagnostics. Read the instructions in
Section 6 , “ Technical support ,” and then contact
Keithley for help in isolating the cause of your problem. Also, contact Keithley if you
have 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, then
reinstall it now. When you are satisfied that it is properly installed, go to
step 11 and retry
selected I/O software tests.
Problem isolation Scheme D: expansion slot connectors
In 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 by
another procedure.
1. Remove computer power again, and install a KPCI-3110 or KPCI-3116 board that you know
is functional. Do not make any I/O connections.
2. Turn computer power on and check operation with the functional board in place. This test
checks 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 shorts
and opens.
5. If operation remains normal to this point, the problem is in the KPCI-3110 or KPCI-3116
board(s) originally in the computer. If you were using more than one board, try each board
one at a time in the computer to determine which is faulty.
Problem isolation Scheme E: user wiring
In Scheme E, after having eliminated other problem causes, you physically check your external
connections to see if they are the problem cause.
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 E:
1. Check the I/O connections between each external signal source and the screw terminal
accessory, one at a time, for short circuits and open circuits. If KPCI-3110 or KPCI-3116
boards were installed in more than one PCI slot, check the I/O connections for all boards.
NOTE
Do not connect the screw terminal accessory to the board during this
scheme.
