Installation
Thischapterdescribeshowtoinstallthe9116seriescards.Thecontentsofthe
package and unpacking information that you should be aware of are described
first.
The 9116 series cards perform an automatic configuration of the IRQ, port
address, and BIOS address. You do not need to set these configurations, as
you would do in ISA form factor DAS cards. Automatic configuration allows
your system to operate more reliable and safe.
2.1 What You Have
In addition to thisUser's Guide, the package should also include the following
items:
•cPCI-9116 or cPCI-9116R with rear I/O adaptor Analog input Data
Acquisition Card
•ADLINK All-in-one Compact Disc
•Software Installation Guide
If any of these items are missing or damaged, contact the dealer from whom
you purchased the product. Save the shipping materials and carton in case
you want to ship or store theproduct in the future.

8•Installation
2.2 Unpacking
The card contains electro-static sensitive components that can be easily be
damaged by static electricity.
Therefore, the card should be handled on a grounded anti-static mat. The
operator should be wearing an anti-static wristband, grounded at the same
point as the anti-static mat.
Inspect the card module carton for obvious damages. Shipping and handling
may cause damage to your module. Be sure there are no shipping and
handling damages on the modules carton before continuing.
After opening the card module carton, extract the system module and place it
only on a grounded anti-static surface with component side up.
Again, inspect the module for damages. Press down on all the socketed IC's to
make sure that they are properly seated. Do this only with the module place on
a firm flat surface.
Note: DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN
DAMAGED.
You are now ready to install your cPCI-9116/R.
