Introduction

NPM301Z is a high-performance embedded serial port-to-Ethernet module, which supports one RS-232, RS-422 or RS-485 to one 100M Ethernet port.
This module has embedded network transformer, which can realize 10Base-T/100Base- TX self-adaptive Ethernet interface just by adding an RJ45 port. The transmission rate of serial port is 300-115200bps. Serial device server supports multiple network protocols, such as TCP, UDP, TELNET, ARP, ICMP, HTTP, DNS and DHCP protocol. It also possesses complete management functions, including Access Control, Rapid Configuration, Online Upgrading and so on. Each serial port supports 4 TCP or UDP session connections, and it also supports RealCom, TCP Server, TCP Client, UDP Server, UDP Client, Pair Master, Pair Slave, UDP Rang, UDP Multicast operating modes and TELNET, WEB access modes. Furthermore, supplied management configuration tool based on Windows platform can guide the user to manage and configure the device, achieving immediate networking of serial device via simple settings. It can provide users with good experience with friendly design of network management system interface, simple and convenient operation.
All settings of NPM301 are realized through serial port or network, which can be used as communication processor between serial device and PC, or remote communication between multiple serial devices. It can be widely used in PLC control and management, Building Automation System, Health Care Automation System, measuring instrument and environmental forces monitoring system.
