2.1 What You Have
In addition to thisUser's Guide, the package includes the following items:
ØPCI-9112 or cPCI-9112 Enhanced Multi-function DAS Card
ØADLINK Software CD
ØSoftware Installation Guide
If any of these items is 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 the product in the future.

Installation • 7
2.2 Unpacking
The card contains sensitive electronic components that can be easily
damaged by static electricity. Failure to perform the procedure outlined
below may damage the on board devices.
The board is packaged in an anti-static bag to avoid damage to the
sensitive IC on the board. After opening the card module carton, extract
the bag and place it only on a grounded anti-static surface to establish
grounding. 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 for obvious damage. Shipping and handling may cause
damage to your module. Be sure there are no shipping and handing
damages on the module before processing.
Note : DO NOT ATTEMPT TO INSTALL A DAMAGED BOARD IN THE
COMPUTER.
You are now ready to install your card.
2.3 Device Installation for Windows Systems
Once Windows 95/98/2000 has started, the Plug and Play function of
Windows system will find the new NuDAQ/NuIPC cards. If this is the first
time to install NuDAQ/NuIPC cards in your Windows system, you will be
informed to input the device information source. Please refer to the
“Software Installation Guide” for the steps of installing the device.

2.5 Jumper Settings
You can set the following configuration by jumpers: the analog input
signal mode, counter’s clock source, and analog output range. The card's
jumpers and switches are preset at the factory. You can change the
jumper settings for your own applications.
For system reliability and safety, the design of PCI-9112 still keeps some
board configurations to be set through jumpers. These setting are listed
as below.

2.7 Clock Source Setting
The programmable interval timer 8254 is used in the PCI-9112. It
provides 3 independent 16-bit programmable down counters. The input of
counter 2 is connected to a precision 2MHz oscillator for internal pacer.
The input of counter 1 is cascaded from the output of counter 2. The
channel 0 is free for user's applications. There are two selections for the
clock source of channel 0 : the internal 2MHz clock or the external clock
signal from connector CN3 pin 35. The setting of clock is shown as Figure
2.3.
