Troubleshooting
KPCI-PIO96 User’s Manual
CAUTION
The tests outlined in the next two sections involve handling of the
KPCI-PIO96 circuit board. Handle the board at the mounting
bracket, using a grounded wrist strap. Do not touch the circuit
traces or connector contacts. If you do not have a grounded wrist
strap, periodically discharge static electricity by placing one hand
firmly on a grounded metal portion of the computer chassis.
Ensure that the computer is turned OFF before installing or
removing a board. Installing or removing a board while power is
ON can damage your computer, the board, or both.
I/O loop-back test
The I/O loop-back test checks input and output bit performance.
You prepare a specially wired loop-back connector that, for any port group, connects the bits of
port A to the corresponding bits of ports B and C. These connections are summarized in Table 5-2.
Table 5-2
Loop-back connection summary
You insert this connector into one of the KPCI-PIO96 I/O connectors. Then, you use a
DriverLINX graphical interface to configure the bits of port A as outputs and ports B and C as
inputs. Thereafter, you use this same DriverLINX graphical interface to set two different bit
patterns at port A and to check in each case for corresponding bit patterns at ports B and C.
If all bits correspond for the first port group, you repeat the loop-back test for each of the other
three port groups. The card is performing satisfactorily if all 96 bits respond appropriately.
Perform the loop-back test as follows:
1. Prepare a loop-back test connector, using a female 50-pin connector that mates with any of
the four I/O connectors on your board. This can be purchased as 3M part no. 3425-6050.
Wire the connector as shown in Figure 5-2.
