Guarantee and Warranty Policy
Guarantee
A thirty day money-back guarantee is provided on all standard products sold. Special
order products are covered by our Limited Warranty, however they may not be returned
for refund or credit. EPROMs, RAM, Flash EPROMs or other forms of solid electronic
media are not returnable for credit - but for replacement only. An extended warranty is
available. Consult the factory.
Refunds
In order to receive a refund on a product for the purchase price, the product must not have
been damaged by the customer or by the common carrier chosen by the customer to return
the goods and the product must be returned complete (meaning all manuals, software,
cables, etc.) within 30 days of receipt and in an as-new and resalable condition. The
“Return Procedure” must be followed to assure a prompt refund.
Restocking Charges
Product returned after 30 days, and before 60 days, of the purchase will be subject to a
minimum 20% restocking charge and charges for any damaged or missing parts. Products
not returned within 60 days of purchase, or products which are not in an as-new and
resaleable condition, are not eligible for a credit return and will be returned to the
customer.
Limited Warranty
Effective April 1, 1998, all products carry a 2-year limited warranty. Within two years of
purchase, ICS Advent will repair or replace, at our option, any defective product. ICS
Advent will service the warranty for all standard catalog products for the first two years

Safety Instructions xi
Safety Instructions
Before handling the PCI-AOB2/4/6 Series, read the following instructions and safety
guidelines to prevent damage to the product and to ensure your own personal safety. Refer
to the “Advisories” section for advisory conventions used in this manual, including the
distinction between Warnings, Cautions, and Notes.
nAlways use caution when handling/operating the computer. Only qualified,
experienced, authorized electronics service personnel should access the interior
of the computer. The power supplies produce high voltages and energy hazards,
which can cause bodily harm.
nUse extreme caution when installing or removing components. Refer to the
installation instructions in this manual for precautions and procedures. If you
have any questions, please contact ICS Advent
Post-Sales Technical Support.
When Working Inside a Computer
Before taking covers off a computer, perform the following steps:
1) Turn off the computer and any peripherals.
2) Disconnect the computer and peripherals from their power sources to prevent
electric shock or system board damage.
3) Follow the guidelines provided in “Protecting Against Electrostatic Discharge”
on the following page.
4) Disconnect any telephone or telecommunications lines from the computer.
CAUTION
High voltages are present inside the chassis when the unit’s power
cord is plugged into an electrical outlet. Disconnect the power cord
from its source before removing the chassis cover. Turning off the
power switch does not remove power to components.

xii PCI-AOB2/4/6 Series User’s Guide
When Operating a Computer
When operating a computer, observe the following operating guidelines:
nTo help prevent electric shock, plug computer power cables into properly
grounded power sources. Use cables equipped with
three-prong plugs to ensure proper grounding. Do not use adapter plugs or
remove the grounding prong from the cable.
nBe sure nothing rests on chassis cables and that cables are not located where they
can be stepped on or tripped over.
nKeep objects out of chassis openings. This can cause fire or electric shock by
shorting out interior components.
nKeep chassis away from radiators and heat sources. Do not block cooling vents
or place chassis in a closed-in wall unit.
nTo help protect chassis from sudden, transient increases and decreases in
electrical power, use a surge suppressor, line conditioner, or uninterruptible
power supply (UPS).
nConsideration should be given to the connection of the equipment to the supply
circuit and the effect that circuit overloading might have on overcurrent
protection and supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
nThe ambient within the rack may be greater than room ambient. Installation
should be such that the amount of air flow required for safe operation is not
compromised. Consideration should be given to the maximum rated ambient.

Regulatory Compliance Statements xiii
Regulatory Compliance
Statements
This chapter describes how to keep the system CE compliant.
CE Certification
This product complies with all applicable European Union (CE) directives. For
computer systems to remain CE compliant, only
CE-compliant parts may be used. Maintaining CE compliance also requires
proper cable and cabling techniques. Although ICS Advent offers accessories, the
customer must ensure that these products are installed with proper shielding to maintain
CE compliance. ICS Advent does not offer engineering services for designing cabling
systems. In addition, ICS Advent will not retest or recertify systems or components that
have been reconfigured by customers.

Description
The PCI-AOB2/4/6 is a half-size card that can be installed in any PCI slot of PC-AT class
computers. It contains two, four, or six double-buffered digital-to-analog converters
(DACs) that provide independent analog output channels of 12-bit resolution. Each
analog output channel can be configured for ranges of:
0V to +2.5V
0V to +5V
0V to +10V
-2.5V to +2.5V
-5V to +5V
-10V to +10V
4mA to 20mA
The analog output channels have a double-buffered input for single-step update and each
is addressed at its own I/O location. Type AD7237 double-buffered, dual, DAC chips are
used. Data are transferred into outer registers a byte at a time (eight LSB's then eight
MSB's) and then transferred into inner registers a word at a time. The analog outputs can
be updated either independently or simultaneously.
The DAC outputs are undefined at power-up. Therefore, in order to prevent excessive
outputs to external circuits, the PCI-AOB2/4/6 contains automatic circuits that set D/A
outputs to less than 15 percent of span at system power-on. Upon power-up, the card is in
the Simultaneous Update mode. After all DACs have been loaded with the desired values,
a software command can be used to switch the reference voltage to its normal value.
Similarly, a software command can be used at any time to set the reference voltage to 15

1-2 PCI-AOB2/4/6 Series User’s Guide
percent causing all DAC outputs to be equal to 15 percent of each DACs programmed
value. For more information, see Chapter 5, Programming.
Each digital I/O line is buffered by a type 74LS245 tristate buffer transceiver capable of
sourcing 15 mA or sinking 24mA (64 mA on request as a factory installed option).
Pull-ups on the card assure that there are no erroneous outputs at power up until the card is
initialized by system software.
