AI-SRVR Series AI-SRVR Series — ARCNET Server to Ethernet Client The AI-SRVR passes data between an ARCNET network and an Ethernet network — giving a client on the Ethernet side access to nodes on the ARCNET side. The unit's role as an ARCNET server is to execute communication requests from an Ethernet client. Any number of Ethernet TCP/IP clients can initiate requests to any node on an ARCNET network. This device will receive ARCNET packets and send the data to Ethernet clients or reverse the process for packets received from Ethernet. A special option called the AI-PROXY mode allows two ARCNET networks to communicate over great distances through an Ethernet network. Compatible with the baseband 2.5 Mbps ARCNET® network Provides connectivity between ARCNET baseband networks and Ethernet Supports coaxial and twisted-pair ARCNET networks including AC- and DC-coupled EIA-485 256 separate ARCNET receive buffer mailboxes Allows monitoring of all ARCNET traffic — including broadcasts A DLL for Windows® clients is provided to facilitate communication Resident web server provides status information Configurable through an EIA-232 console port Panel-mount or DIN-rail mount RoHS compliant

Data Sheet — AI-SRVR Series ARCNET and Ethernet have varied medium access methods, frame sizes and link layer protocols. The most popular Ethernet transport layer protocol is TCP/IP, but ARCNET is usually found in embedded applications that do not use TCP/IP. ARCNET does not use a universal application layer — so ARCNET works best when passing raw packets. The Ethernet client must interpret the meaning of the raw packets. This approach allows any ARCNET network to be queried by any Ethernet client regardless of the application layer protocol being used with ARCNET. Each of 256 mailboxes has...

Data Sheet — AI-SRVR Series The AI-SRVR can also function in the AI-PROXY mode which allows ARCNET devices on separate networks to exchange data over an Ethernet backbone. One AI-SRVR node is needed for each ARCNET device because each AI-SRVR node can function as a proxy for only one ARCNET device. The proxy receives packets in a local ARCNET network and sends them over the Ethernet cabling to a remote AI-SRVR for re-transmission on the remote network. In the simplest scenario (Figure 1), each AI-SRVR-1 represents one ARCNET node. If several nodes in one network must communicate with...
