Troubleshooting

Testing the board and host computer
To isolate the problem to the PIO-24 board or to the host computer, use the follow-
ing steps:
CAUTION
Removing a board with the power ON can cause damage to your
board and/or computer.
1.
Turn the power to the host computer OFF, and remove power connections to
the computer.
2.
While keeping connections to accessories intact, unplug the cable to the main
I/O connector of the PIO-24 board.
3.
Remove the board from the computer and visually check for damage. If a
board is obviously damaged, refer to
Technical support
on page 6-6 for infor-
mation on returning the board.
4.
With the PIO-24 board out of the computer, check the computer for proper
operation. Power up the computer and perform any necessary diagnostics.
At this point, if you have another PIO-24 board that you know is functional, you
can test the slot and I/O connections using the instructions in the next section. If you
do not have another board, refer to the instructions on page 6 before calling Keithley
Instruments for technical support.
Testing the accessory slot and I/O connections
When you are sure that the computer is operating properly, test the computer
accessory slot and I/O connections using another PIO-24 board that you know is
functional. To test the computer accessory slot and the I/O connections, follow these
steps:
1.
Remove computer power again, and install a PIO-24 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 problem occurred, use the functional board to test
the other slot, as well.
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 PIO-24
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.
6.
If you cannot isolate the problem, refer to the next section for instructions on
obtaining assistance.
