Troubleshooting
Testing the PIO-32 Series Board and Host Computer
To isolate the problem to the PIO-32 Series board or to the host computer,
perform the following steps.
Warning:
Do not connect voltages greater than 30V RMS, 42.4V peak,
or 60VDC to any input or output on this board.
Live voltages can still be present on the board even when the computer is
turned off. To protect you and the circuit, Keithley provides covers with
the PIO-32 Series boards. Though you can remove the covers to service
the PIO-32 Series boards,
do not use these boards with the covers
removed!
In addition, disconnect all cables when servicing these boards.
1. Turn the power to the host computer OFF, and remove power
connections to the computer.
Caution:
Removing a board with the power ON can cause damage to
your board and/or computer.
2. Unplug the accessory connector(s) or cable(s) from the PIO-32 Series
board(s), keeping the connections intact on the accessory board(s).
3. Remove the PIO-32 Series board(s) from the computer and visually
check for damage. If a board is obviously damaged, refer to page 6-6
for information on returning the board.
4. With the PIO-32 Series board(s) 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-32 Series 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 6-6 before calling Keithley Applications
Engineering.
