HOW TO USE THIS MANUAL
This manual uses typographical and iconic conventions to assist the reader in
understanding the content. This section will define the text formatting and icons used in
the rest of the manual. This manual is formatted with a ‘Scholar Margin’ where many
tips, symbols or icons will be located.
Text Usage
• BOLD–text that is written in bold letters indicates important information and
table, figure, and chapter references.
• BOLD ITALIC–will designate DDC Part Numbers.
• Courier New–is used to indicate code examples.
• <…> - Indicates user entered text or commands.
Symbols and Icons
The Idea/Tip icon will be used to identify a handy bit of supplementary
information that may be useful to the user.
The Note Icon signifies important supplementary information that will be
useful to the user.
The Caution icon identifies important information that presents a
possibility of damage to the product if not heeded.
Much stronger than a Caution, the Warning icon presents information
pertaining to hazards that will cause damage to the product and possible
injury to the user.

The Reference icon indicates that there is related material in this
manual or in another specified document.
The Disk Icon describes information that is related to software.
Special Handling and Cautions
The SB-3621X series uses state-of-the-art components, and proper care should
be used to ensure that the device will not be damaged by Electrical Static
Discharge (ESD), physical shock, or improper power surges and that precautions
are taken to avoid electrocution.
• Turn off power to the PC and unplug from wall.
• NEVER insert or remove card with power turned on.
• Ensure that standard ESD precautions are followed. As a
minimum, one hand should be grounded to the power supply in
order to equalize the static potential.
• Do not store disks in environments exposed to excessive heat,
magnetic fields or radiation.

INTRODUCTION
The SB-3621X provides intelligent interfacing between a Synchro or
Resolver's output and a PCI Bus. The SB-3621X is packaged on a full-size
IBM PC/AT printed circuit board with a PCI bus interface. Features of the
board include:
• Plug-and-Play (PnP) compatible for easy installation
• Utilizes six RD-19230 converters
• Software Programmable Resolution (10,12,14 or 16 bits)
• Software Programmable Bandwidth
• On-Board Oscillator option
• Transformer Isolation Available for 60 Hz or 400 Hz
• Turns Counter
• Self Test
Application software has the capability to display position for either six
channels of single speed or three channels of two-speed. Included with each
SB-3621X PCI Card is the DDC Toolbox library with example source code
that allows users to easily write their own application software for the card.
What is included in this manual?
This manual contains a detailed installation guide for the SB-3621X PCI Card
and a basic overview of the software supplied with the card. Toolbox Library,
DLL, and Driver installations for Windows®95, 98, 2000, Windows NT®and
Linux will be covered in this manual.
The library software provides a level of abstraction such that it is not
necessary to understand the operation of the chip set. This manual provides
an introduction to the library.
System Requirements
The PC must be configured with a Windows 95, 98, 2000, Windows NT or
Linux operating system.

HARDWARE INSTALLATION
HARDWARE INSTALLATION
Card Installation
The SB-3621X card is a PCI Target device and may be inserted into any PCI
2.1, or higher, compatible slot. Note that this card only operates on a 5V PCI
slot, and not on a 3.3V PCI slot. When installing the card, the following should
be observed:
NEVER insert or remove the card with the power turned on.
ALWAYS take proper precautions to guard against static damage. Use a
wrist strap if available, or ensure proper static grounding by touching the
power supply cover WITH POWER OFF.
Insert the card at a slight angle so that the connectors first protrude from the
rear opening and then gently press the card into the motherboard connector.
Secure with proper hardware.
Make sure that adjacent cabling and wiring do not hinder the airflow around
the card.
This card is designed as a Plug-and-Play device and as such, there are no
jumpers or switches to be set for address and interrupt selection. Figure 1
shows a block diagram for the Synchro/Resolver-to-digital PCI Card.

Linux Driver Installation
Linux is a free Unix-type operating system developed under the GNU General
Public License. The source code for Linux is freely available to everyone.
Since it’s inception in 1991, individuals, university students and companies
began distributing Linux with their own choice of packages bound around the
original kernel. This is where the concept of the "distribution" was born. This
also complicates providing Linux support for our hardware because there are
over 150 distributions of Linux. Red Hat Linux is one of the most popular
distributions in the world. For this reason we have developed and tested our
Linux support on one of the many Red Hat distributions. This guide was
prepared using Red Hat® Linux® 7.2 kernal versions 2.2.16-22.
To complete the Linux setup, the user should be familiar with basic Linux
procedures and commands (mounting, compiling, etc.). View the readme.txt
file for the latest installation information. If you are unfamiliar with Linux, try
visiting some of these sites for helpful documentation:
• www.ora.com
• www.kernel.org
• www.linux.org
