ARCNET for Control - 2

Dear Customer, In Industrial networking, there has been a long history of technologies battling for dominance. There is a long list of losers, relegated to the bone yard of obsolete technology. And a few winners, like Ethernet and TCP/IPand ARCNET > ׮ . While ARCNET did not achieve the vast popularity of Ethernet, still after two decades it continues to be used in tens of thousands of installations. Today, ARCNET is still being designed into new products. Why? Because as a high-speed, long- distance Ethernet alternative, it is inexpensive, well-supported, provides ultra-reliable performance...

Simple Microprocessor Bus Interface Reliable Message Delivery Variable Data Rate Up to 10 Mbps ARCNET has other unique features that facilitate embedded design development. The COM20020 family of ARCNET controllers were designed for a simple eight-bit bus microprocessor interface. The complete communication protocol is handled by the ARCNET controller. This includes token-passing, network configuration and error handling. Unlike Ethernet, ARCNET has built-in flow control. ARCNET 6 Another problem with Ethernet is the requirement to add a transport-layer protocol. Of course, the most popular...

Regulatory Requirements Simply embracing ARCNET standards does not remove the requirement to conform to various agency regulations not required in the office. Seldom does office-grade ARCNET equipment meet the unique requirements of industrial automation or even building automation. ARC Control products are designed and tested to the higher electromagnetic compatibility (EMC) immunity standards required for industrial equipment. Some products are UL 1950 listed for use in information technology equipment. Others are UL 864 recognized for smoke and fire-protective applications. All the...

-FOG Fiber Optic Glass (Multimode) (ST or SMA Connectors) -CXS Coaxial Star (BNC Connector) Fiber optic cable can be supported by ARCNET as well. The -FOG transceiver identifies support for a duplex 850 nm multimode link. One port is used for receive and one for transmit. Computer Bus Structures Transceiver Options -CXB Coaxial Bus (BNC Connector) This is the original ARCNET transceiver very much in use today. Operating at 2.5 Mbps, this transceiver is intended for either point-to-point, star or distributed star topologies. A BNC connector completes the connection to RG-62/u coaxial cable....

C BNC Coaxial Connectorח"Baby" NC connectors are used on coaxial cable transceivers such as the -CXS and -CXB. RG-62/u cable is generally used with this connector. Connectors ST ST Fiber Optic Connectorח"Straight Tip" fiber optic connector commonly used in the industry. This quarter-turn connector prevents the possibility of over tightening. Depending upon the transceiver selected, connector options vary even within a transceiver type. A selection guide has been provided to assist in determining what connector is available. Connector details are included in the technical portion of the...

T he CPCI22 Series links CompactPCI bus compatible computers with the ARCNET Local Area Network. The combination of a low-profile, 3U form factor, hot-swap capability, and solid performance can be found in this product. These features make it well-suited for use in industrial and telecommunications applications. The CPCI22 bus allows for jumperless configuration and Plug and Play (PnP) operation. Hot-swapping is an essential benefit for operators of high-availability systems. The module functions with either an NDIS driver or with a null stack driver in a Windows environment. This network...
