Troubleshooting
KPCI-PIO96 User’s Manual
If your KPCI-PIO96 board is not operating properly, use the information in this section to isolate
the problem before calling Keithley Applications Engineering. If you then need to contact an
applications engineer, refer to “Technical support.”
Identifying symptoms and possible causes
Try to isolate the problem using Table 5-1, which lists general symptoms and possible solutions
for KPCI-PIO96 board problems.
If your board is not operating properly after using the information in Table 5-1, continue with the
next section to further isolate the problem.

Basic troubleshooting information
Symptom
Possible cause
Possible cause validation/solution
Computer does
not boot when
board is installed
Resource conflict. KPCI-PIO
series board is conflicting with
other boards in the system.
1. Validate the cause of the conflict.
Temporarily unplug boards —especially ISA
boards
1
—one at a time, and try booting the
computer. Repeat until a boot is attained.
2. Try resolving conflicts by reinstalling one
PCI board at a time and rebooting after each
reinstallation.

However, you may ultimately
need to change ISA board resource allocations,
such as base address or interrupt assignments.
Board not seated properly.
Check the installation of the board.
The power supply of the host
computer is too small to handle
all the system resources.
Check the needs of all system resources and
obtain a larger power supply.
Board does not
respond to the
PIO Test Panel.
DriverLINX is not
installed properly.
Check the Windows® Device Manager and
follow the installation troubleshooting
instructions in the DriverLINX on-line help.
The board is incorrectly
aligned in the expansion slot.
Check the board for proper seating.
The board is damaged.
Contact Keithley Applications Engineering.
Data appears to
be invalid.
An open connection exists.
Check screw terminal wiring.
Transducer is not connected
to channel being read.
Check the transducer connections.
One or more external circuits
are not TTL compatible
Check external circuit schematics. Test
external circuits with a logic probe.
Intermittent
operation.
Vibrations or loose
connections exist.
Cushion source of vibration and
tighten connections.
The board is overheating.
Check environmental and ambient
temperature. See your
computer documentation.
Electrical noise exists.
Provide better shielding or reroute
unshielded wiring.
System lockup
during operation.
A timing error occurred.
Restart your computer. Then analyze your
program by debugging and narrowing the list
of possible failure locations.

Plug and Play cannot tell if an ISA board already uses an address it assigns to a PCI board.

Plug and Play may then assign different, nonconflicting addresses to the PCI boards.
