Unpacking
Your PC-DIO-24 board is shipped in an antistatic package to prevent electrostatic damage to the
board. Electrostatic discharge can damage several components on the board. To avoid such
damage in handling the board, take the following precautions:
• Ground yourself via a grounding strap or by holding a grounded object.
• Touch the antistatic package to a metal part of your PC chassis before removing the board
from the package.
• Remove the board from the package and inspect the board for loose components or any other
sign of damage. Notify National Instruments if the board appears damaged in any way. Do
not install a damaged board into your computer.
• Never touch the exposed pins of connectors.
