Quad Port Fast Ethernet Controller
10BASE-T (10Mbps) and 100BASE-TX (100Mbps) Across Twisted-Pair Cable

Ethernet has evolved as the networking technology standard. A recent powerful trend is Ethernet in a fieldbus environment. Beginning at the actor/sensor module, up to the process control system, forward to the management database - Ethernet offers total connectivity for all areas of an enterprise.

With the CN4-BELL, EKF introduces a quad Fast Ethernet networking interface controller for CompactPCI® systems. Any individual RJ45 jack provides for attachment to 10Base-T and 100Base-TX based LANs across a CAT5/6 twisted-pair cable, suitable for distances of up to 105m. Featuring auto-negotiation and full-duplex mode, the maximum data transfer rate is 200Mbps at any port.

As a 3U board (single size Eurocard), the CN4-BELL replaces up to four single-port Fast Ethernet NICs (Network Interface Controller). Consequently, the CN4-BELL occupies four individual MAC- respective IP-addresses.

The CN4-BELL is suitable for a wide range of applications with need for multiple networking controllers, e.g. firewall, gateway, router, or as a fieldbus data concentrator. High availability systems profit from the redundancy achieved when using several Ethernet ports in parallel.

Drivers are available by download for all popular operating systems (e.g. Windows, Linux).
