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:
wPCI-9812/10 Enhanced Multi-function Data Acquisition Card
w5 BNC terminators
wADLink All-in-one CD
wSoftware 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
PCIconfiguration
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 Playfunction
of Windows system will find the new NuDAQ/NuIPC cards. If this is
the first time to install NuDAQ/NuIPC cards in your Windowssystem,
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/Dconverter.
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.
