Introduction
NS 4 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 PCB boards. 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 operating status indicator pins to external LEDs for convenient status monitoring.
Features
- 10M Ethernet interface
- Configuration via configuration tool and AT commands
- Server mode supports multiple Socket connections
- Baud rate: 2400~115200bps, multiple authentication methods
- Configurable DNS
- Timeout restart with customizable interval
- Short connection mode with customizable interval
- Serial port buffer clearing
- Hardware factory reset
