ARCNET® Network Interface Modules with USB Interface

INSTALLATION GUIDE

INTRODUCTION

The USB22 Series of ARCNET Network Interface Modules (NIMs) links Universal Serial Bus (USB) computers with the ARCNET Local Area Network (LAN). USB has become popular for connecting desktop or laptop computers to peripherals because of its very high-speed interface (up to 480 Mbps) and its convenience of a powered exterior interface with no need to open the computer.

Each USB22 includes a COM20022 ARCNET controller that can support data rates up to 10 Mbps and a microcontroller to transfer data between the ARCNET and either USB 2.0 or USB 1.1 devices. The NIM is powered from a computer USB port or a USB hub. Models exist for the most popular ARCNET physical layers.

A USB cable and a disk with software for Windows® 2000/XP/Vista/7 is also provided. When a USB cable first connects the NIM to a machine using Windows 2K/XP/Vista/7 and you are prompted for a driver, use the USB driver provided on the CD-ROM. Follow the instructions provided by Windows to install this driver. If Windows reports that this driver has not been tested, just select “continue” and complete the installation.
