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 is also provided.
NOTE:
The USB22 Series of NIMs are for users who are willing and
able to modify their application-layer software. Some OEM companies
have modified their software to work with the USB22. If your
application is not provided by one of these companies, you cannot use
the USB22 —
unless you rewrite your application software
or hire a
software engineer to do it. (See the
SOFTWARE
section of this
installation guide for information about the
Software Developer Kit
.)
If USB22-compliant software is provided by your OEM and you
encounter installation difficulties, you should contact your OEM for
resolution of your issue — because Contemporary Controls has no
knowledge of the OEM software.
