6Introduction

DASYLabTM PRO

DASYLab is an easy-to-use software package, providing easy-

setup instrument functions such as FFT analysis. Please contact

ADLINK for DASYLab PRO, which includes DASYLab and

ADLINK hardware drivers.

Installation 7

2 Installation

PCI-9812/10 will perform an automatic configuration of the IRQ

and I/O port address. There is no need to set any configuration,

as you would use in an ISA form factor DAS card. For system

reliability, it is necessary to manually assign some critical settings

for analog input and output, as these settings will not be changed

after your data acquisition system configuration is decided. The

configuration cannot be changed using only the software package

when your system is running.

Please follow the steps below to install the PCI-9812/10 products.

X Go through the checklist (section 2.1)

X Unpacking (section 2.2)

X Check the PCB (section 2.3)

X Install the hardware (section 2.4)

2.1 Checklist

In addition to this User's Guide, the package includes the following

items:

X PCI-9812/10 Enhanced Multi-function Data Acquisition

Card

X Five BNC terminators

X ADLINK All-in-one CD

X Software Installation Guide

If any of these items are missing or damaged, contact the dealer

from whom this product was purchased. Save the shipping

materials and carton for future shipping or storage.

8Installation

2.2 Unpacking

Your PCI-9812/10 card contains electro-static sensitive

components that can easily be damaged by static electricity.

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 they are properly seated. Do this only

with the module placed on a flat firm surface.

You are now ready to install your card.

Note: Do not attempt to install a damaged board onto the

computer.

10 Installation

2.4 Hardware Installation Outline

PCI configuration

The PCI cards (or CompactPCI cards) are equipped with a Plug

and Play PCI controller, it can request base addresses and

interrupt according to PCI standard. The system BIOS will install

the system resource based on the PCI cards’ configuration

registers and system parameters (which are set by system BIOS).

Interrupt assignment and memory usage (I/O port locations) of the

PCI cards can be assigned by system BIOS only. These system

resource assignments are done on a board-by-board basis. It is

not recommended to assign the system resource by any other

methods.

PCI slot selection

The PCI card can be inserted to any PCI slot without any

configuration for system resource. Please note that the PCI

system board and slot must provide bus-mastering capability to

operate this board well.

Installation Instructions

1. Turn off your computer

2. Turn off all accessories (printer, modem, monitor, etc.)

connected to your computer.

3. Remove the cover from your computer.

4. Setup jumpers on the PCI or CompactPCI card.

5. Select a 32-bit PCI slot. PCI slot are short than ISA or

EISA slots, and are usually white or ivory.

6. Before handling the PCI cards, discharge any static

buildup on your body by touching the metal case of the

computer. Hold the edge and do not touch the

components.

7. Position the board into the PCI slot selected.

8. Secure the card in place at the rear panel of the system.
