Installation

Guide

This guide tells how to complete the following steps for a successful installation.

Step 1 – Install Software

…… page 2

Step 2 – Install Boards in Available PCI Bus-Slots

…… page 3

Step 3 – Configure Boards

….. page 5

Step 4 – Test Hardware

….. page 6

Reference Note:

After you have completed the installation you should refer to the electronic documents that
were automatically installed onto your hard drive as a part of product support. The default
location is in the

Programs

group, which can be accessed from the Windows Desktop.

You should keep your DaqBoard’s serial number and your DaqView/500 authorization code (if applicable)
with this document. Space is provided below for recording up to 4 board numbers and their PCI bus-slot
locations. The board serial number and board type (500 or 505) is located on the solder-side of the board

.

Board 2

Board 3

Board 4

The host PC can support up to four Boards.

DaqView/500 Authorization Code

____________________________

Customers who ordered DaqView/500 can find their authorization code on the authorization
code sheet located inside the sleeve of the install CD.

Customers who did not order DaqView/500 can run a 30-day free trial version, as discussed
elsewhere in the User’s Manual.

CAUTION

Take ESD precautions (packaging, proper handling, grounded wrist strap, etc.)

Use care to avoid touching board surfaces and onboard components. Only handle boards
by their edges (or ORBs, if applicable). Ensure boards do not come into contact with
foreign elements such as oils, water, and industrial particulate.
