Installation

This chapter describes how to install the PCI-9812/10. Firstly,

please read the contents in the package and unpacking information

and following these instructions carefully.

The 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, because these settings will not be

changed after your data acquisition system configuration is decided.

The settings will let your system perform reliably & safely (user can

not change the configuration by software directly) when your

system is running.

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

2.1 What You Have

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

items:

w PCI-9812/10 Enhanced Multi-function Data Acquisition Card

w 5 BNC terminators

w ADLink All-in-one CD

w Software Installation Guide

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

whom you purchased the product for replacement. Save the

shipping materials and carton in case you want to ship or store the

product in the future.

2.2 Unpacking

Your PCI-9812/10 card contains sensitive electronic components

that can be easily 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 damage. Shipping and

handling may cause damage to your module. Be sure there is no

shipping and handing damage on the module before processing.

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 damage. 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 PCI-9812/10.

2.4 Hardware Installation Outline

PCI configuration

The PCI cards (or CompactPCI cards) are equipped with 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 suggested 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 Procedures

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 you selected.

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

2.5 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.

3.2 Analog Input Impedance Setting

This section describes the characteristics of the different inputs of

the PCI-9812/10.

3.2.1 Analog Input

PCI-9812/10 has four analog input channels which are connected

through connectors J1 ~ J4. The input impedance and input

amplitude range can be changed through soldering the gap

switches on board (refer to PCI-9812/10’s layout). A solder gap

switch consists of two copper pads, the switch can be turned on by

soldering these two pads together. All the four channels have the

same way to configure their input characteristics, and only channel

0 is discussed here. There are 2 solder gap switches, named C0LO

(channel 0 low impedance) and C05V (channel 0 5V input), to setup

the input characteristics of channel 0. (Please refer to fig. 2.1 in

section 2.3)

C0LO C05V Input Impedance Input Range

Open Open High (~15M Ohm) ±1V

Open Close 1.25K Ohm ± 5V

Close Open Low (50 Ohm) ± 1V (default)

Close Close Low (50 Ohm) ± 5V

CAUTION : When the input channel is configured as a high

impedance input, DO NOT leave the input connector

unconnected, the input connector must be connected

to a low impedance signal source to provide a return

path for the input bias current (<= 15 µA), otherwise

high voltage will build up at the input of A/D converter.

That could damage the A/D converter.

Note : 75 ohm input impedance can be achieved by either :

1. Replace R95 by a 75 ohm resistor and close C0LO.

2. Place a T-connector with a 75 ohm terminator on J1

and open C0LO.
