NEW RELEASE OF THE USB22 SERIES!

Contemporary Controls Announces the Release of the USB22 Series of USB 2.0 to ARCNET® Adapters

In efforts to overcome the inherent non-real-time response associated with today’s traditional operating systems such as Windows®, Contemporary Controls has released the USB22 Series of USB 2.0 to ARCNET adapters. The USB22 incorporates a deep memory buffer to hold messages until the OS can service the device via its high-speed USB 2.0 connection.  Using this approach missed messages is rare even while operating at 10 Mbps, which is four times the standard ARCNET data rate of 2.5 Mbps.

The Universal Serial Bus (USB) has become a well-known method for connecting either desktop or laptop computers to peripherals because it provides a very high-speed interface (up to 480 Mbps).  Designed with the COM20022 controller, the USB22 represents the latest ARCNET technology supporting data rates as high as 10 Mbps. Models exist for the most recognized ARCNET physical layers.  A high-performance microcontroller handles the transfer of data between AECNET and USB.  The NIM is powered from the USB port on the computer or from a USB hub. This product is compatible with the USB 2.0 standard, thereby allowing for an extremely fast and convenient means of accessing an ARCNET network.  The USB22 is backwards compatible and will also operate with the earlier full-speed (12 Mbps) USB 1.1 standard. 

The USB22 receives its power from the USB port on the computer, and it will operate with or without a USB hub.  It is available in several modules that will support either DC or AC-coupled EIA-485, coaxial bus or twisted-pair networks. It is shipped with a CD containing a Windows 2k/XP compatible DLL and driver, along with a USB cable.
