ARCNET has many characteristics that make it ideal for industrial and embedded networking environments. These include its deterministic nature, its high reliability and fault tolerance, and its adaptability to a wide variety of cabling media and configurations. As the market leader in ARCNET devices, we offer a full spectrum of solutions to meet your price and performance needs.

CircLink, an ARCNET derivative, further improves on the protocol by eliminating the need for an external processor. It is optimized as a wire-replacement technology inside industrial and commercial machines.
