Introduction

NS 2 is a serial-to-Ethernet server module that enables conversion between serial data and Ethernet data. It supports multiple Modbus gateway modes as well as TCP/UDP/MQTT/HTTP IoT gateway modes, meeting the networking requirements of various serial devices and PLCs. The module adopts an LCC package for easy integration into user PCBs. The NS 8-TB test kit features a built-in USB-to-TTL circuit, eliminating the need for an external converter. It exposes reset and factory restore pins for external button use, and connects status indicator pins to external LEDs for convenient operation and status monitoring.
