Chapter 1—Introduction and Description
The processor, along with 256K bytes of RAM, works to allocate resources dynamically to the most
active port. The ISI then generates one interrupt for an entire block of information and transfers the block
to the system’s microprocessor.
The ISI5634PCI has eight Mini RJ-11 jacks. It is a 3/4 size add-on card that supports a high-speed
interface up to 230 Kbps.
How to Use This Manual
This manual contains hardware and operating system driver installation procedures, technical support
and warranty information, and an appendix for additional information. Hardware configuration and
installation procedures are described in Chapter 2. Installing the ISI5634PCI card also involves linking a
driver to the operating system. This information is provided in Chapter 3.
It is assumed you have basic PC skills. Therefore, we have not included step-by-step instructions for
basic operations such as logging in and file editing, etc.
Most of the steps listed in the driver installation section instruct you to press Enter. This is a reference to
the key commonly known as the Enter, carriage-return, or Return key. Also, please note the difference
between the letter O and the number 0. Both the letter and the number may be used in this manual.
ISI5634PCI Applications
The ISI5634PCI is an ideal solution for adding ports when a powerful microcomputer used as a server or
host lacks enough connectivity to accommodate the desired number of users. The ISI5634PCI provides
eight additional serial ports with every card installed, with a potential of four additional cards installed per
system—for a total of thirty-two serial ports per system.

• Four modular telephone cables (Eight with the ISI5634PCI/8 model)
• Quick Start Guide (printed manual)
• A full User Guide on CD-ROM
