Unit provides connectivity between Arcnet and Ethernet networks

24 August 2005 Computer/Embedded Technology

Contemporary Controls has designed a connectivity device that solves the problem of allowing data to pass between Arcnet and Ethernet networks.

The AI-SRVR provides connectivity between Arcnet and Ethernet networks, allowing a client on the Ethernet side access to nodes on the Arcnet side. The AI-SRVR operates as an Arcnet server by executing communication requests from an Ethernet client. Any number of Ethernet TCP/IP clients can initiate requests to any node on an Arcnet network. The AI-SRVR will receive Arcnet packets and send the data to Ethernet clients or reverse the process for transmitted packets.

Configuration of the AI-SRVR is achieved through an EIA-232 serial port. The Ethernet IP address and Arcnet node address are set in this fashion. Once configured, a resident web server can be accessed to determine the operational status of the AI-SRVR.

This device can also function in the 'AI-Proxy' mode. When used in this mode, the AI-SRVR allows Arcnet devices on separate networks to communicate directly over an Ethernet network. One AI-SRVR is required for each Arcnet device as each AI-SRVR acts as a 'proxy' for one Arcnet device.

The unit can be powered from a wide range of low-voltage AC or DC power sources and provisions exist for redundant power connections. Four models are available, each for a type of physical Arcnet network. Versions exist for coaxial bus, twisted-pair bus, and EIA-485 AC- or DC-coupled networks.
