Along with this increased market demand is a change in application requirements. Where single channel Ethernet used to be sufficient, many applications such as wireless remote base stations and industrial networking now require DUAL Port functionality for redundancy or system management. The DP83849I is a highly reliable, feature rich device perfectly suited for industrial applications enabling Ethernet on the factory floor. The DP83849I features two fully independent 10/100 ports for multi-port applications. NATIONAL’s unique port switching capability also allows the two ports to be configured to provide fully integrated range extension, media conversion, hardware based failover and port monitoring. The DP83849I provides optimum flexibility in MPU selection by supporting both MII and RMII interfaces. In addition this device includes a powerful new diagnostics tool to ensure initial network operation and maintenance. In addition to the TDR scheme, commonly used for detecting faults during installation, NATIONAL’s innovative cable diagnostics provides for real time continuous monitorin...
