If you cannot identify the problem using the information in Table 7-1,
refer to the next subsection to determine whether the problem is in the
host computer or in the DDA-08/16 board.
Testing Board and Host Computer
To determine whether the problem is in the host computer or in the
DDA-08/16 board, perform the following steps:
1. Remove power connections to the host computer.
2. Unplug the accessory connector(s) or cable(s) from the DDA-08/16
board(s), keeping the connections intact on the accessory board(s).
3. Remove the DDA-08/16 board(s) from the computer and visually
check for damage. If a board is obviously damaged, refer to page 7-6
for information on returning the board.
4. With the DDA-08/16 board(s) out of the computer, check the
computer for proper operation. Power up the computer and perform
any necessary diagnostics.
If you have another DDA-08/16 board that you know is functional, refer
to the next section to determine whether the problem is in the accessory
slot or in the I/O connections. If you do not have another board, refer to
page 7-6 for information on how to contact an applications engineer.
