The BOCALANcard 100/10 provides an affordable high-performance 100Mbps Ethernet solution for IEEE 802.3 100Base-TX networks. It provides 10 times the bandwidth of existing 10Base-T networks, and features a bus-mastering architecture for single-step data transfers to and from the host PC. This enables higher data transfer rates, increased throughput and low CPU overhead. Not quite ready to upgrade to 100Mbps technology? No problem - the BOCALANcard 100/10 easily runs on your existing 10Base-T network. The unit comes with two RJ-45 connectors labeled 100Mbps and 10Mbps. Future upgrades are just a matter of simply plugging the network cable into the 100Mbps connector. And, with Plug and Play, installing the BOCALANcard 100/10 is quick and easy. The BOCALANcard 100/10 is automatically configured at system power up, in conformance with the PCI Rev. 2.0 standard. This means no jumpers to set or change. Transmit, link/receive and port select LEDs allow you to monitor activity on the network.
