1.Support full duplex, high speed converting, and no packet lost.ZLAN5143D is the first type of full duplex, continuous, and low cost serial server in industry. It support simultaneously converting between Ethernet &Serial with large bulk of data with no pause, and also no data is lost. 2.High cost performance.ZLAN5143D is designed by concept of intensification, after ensure the stability. It highly takes the cost of networking upgrading in count 3.Support TCP Server, TCP Client, UDP model, UDP multicast. 4.Support baud rate 1200-115200bps, data size 5-9bits, parity of None, Odd, Even, Mark, Space. 5. Provide device management library (Windows DLL library). It's convenient for user to develop program with VC, VB, Delphi, C++ Builder. User need only use read or write function to communicate with ZLAN5143D. The innovative disconnecting detecting method, whether ZLAN5143D work in TCP Server mode or TCP Client mode it can automatically reestablishing connection after network broken, to ensure the data real-time accessibility. With build-in Web server, its parameters can be modified by web browser. Support DHCP, easy for IP management and solve IP confliction. Support DNS. It fulfills the need of access data server through domain name. Support 100 TCP connections communicate with network modules at the same time. As a TCP client, can connect to 7 destination IP. Flexible serial data framing setting. It fulfills all kinds of serial data frame requirement. UDP mode support dynamic destination address mode. It helps for multi-user mange one serial server. Support searching serial servers and modifying parameters through Internet remotely Support parameter modifying protection, preventing modifying by accident. Support running with default parameters. Build-in 2 KV electrical plus protection in R
