The USB22 Series Provides a Low-Cost Solution for Transferring ARCNET Data Over High-Speed USBDowners Grove, Illinois (April 12, 2006) ¯ “Contemporary Controls introduces the only ARCNET interface in the industry providing a cost-effective solution for transferring ARCNET data over high-speed USB,” says George Karones, Engineering Manager at Contemporary Controls.The USB22 Series of Network Interface Modules (NIMs) allows easy connectivity between either desktop or laptop computers to peripherals because it provides a very high-speed interface (up to 480 Mbps) and does not require inserting a separate NIM into the computer. This NIM is designed with the COM20022 controller employing the latest ARCNET technology supporting data rates up to 10 Mbps. The USB22 includes a high-speed microcontroller that transfers the data between ARCNET and USB. It has up to 128 Kbytes of ARCNET receiver buffering to handle the reception of broadcast messages or the monitoring of networks with high traffic levels. With a 480 Mbps USB link, the possibility of dropping ARCNET packets is remote.It is compatible with the USB 2.0 standard which falls into the high speed category of this specification. Since most modern computers are equipped with a USB port, you only need a USB connection between the computer and the USB22 in either mobile or stationery systems. This NIM will also operate with the earlier lower-speed USB 1.1 standard. This device receives its power from the USB port on the USB computer and will function with or without a USB hub. It is available in several models supporting either DC or AC-coupled EIA-485, coaxial bus or twisted-bus networks.It is shipped with a CD containing a Windows 2K/XP compatible DLL and driver, along with a USB cable. Models exist for the most popular ARCNET physical layers.
