Testing the Board and Host Computer
To isolate the problem to the DDA-06 board or to the host computer, use
the following steps:
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. While keeping connections to any accessory board intact, unplug the
accessory connector or cable from the DDA-06 board.
3. Remove the DDA-06 board from the computer and visually check for
damage. If a board is obviously damaged, refer to “Technical
Support” on page 8-5 for information on returning the board.
4. With the DDA-06 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 DDA-06 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 8-5 before calling Keithley Technical Support.
