What Next?
At this point the hardware installation for your AccelePort Xe EIA-422
host adapter is complete. However, since the adapter must have software
downloaded to its RAM before it becomes functional, you must next
install the software drivers for your operating system.
• Read the instruction booklet for the CD-ROM that came with your
adapter for instructions on installing software.
• View the on-line documentation on the CD-ROM for more informa-
tion about AccelePort products.

Introduction

® ™
An AccelePort Xe EIA-422 host adapter easily adds EIA-422 ports to
your computer, allowing you to cable EIA-422 peripheral devices directly
to your computer.
As shown in the figure below, an Xe host adapter has one connector to
which a special Digi cable assembly is attached to provide the peripheral
port connections. The cable assembly is available with either DB-9 or
DB-25 connectors at the peripheral end of the cable.
