Nexisense ZLAN5143D Fully isolated serial port server Product Definition
The Nexisense ZLAN5143D Fully isolated serial port server is a high-performance RS485 serial serverand IoT communication gateway specifically designed for industrial scenarios. It integratesserial-to-Ethernet, Modbus TCP/RTU protocol conversion, MQTT data reporting, RS485 to JSON, and more,enabling seamless communication between traditional industrial devices and modern Ethernet-based systems, allowing remote control, data acquisition, and protocol conversion.
Working Principle
The Nexisense ZLAN5143D Fully isolated serial port server operates on the principle of serial data pass-through and protocol relay technology:
As a serial server:The RJ45 interface connects to LAN/WAN, allowing remote reading and writing of data from RS485 buses via TCP/UDP orvirtual serial ports, offering transparent data forwarding.
As a Modbus Gateway: The device converts Modbus TCP to Modbus RTU, allowing seamless communication between upper-level machines and RS485 slaves.
As an MQTT IoT Gateway: The data collected from serial ports is parsedinto JSON format and pushed to cloud platforms via MQTT protocol(such as Alibaba Cloud, Baidu Cloud, OneNet, etc.).
Multi-host Concurrent Mechanism: It supports multiple upper-level machines accessing the same RS485 slave simultaneously, ensuring redundancy and multi-task concurrency.
Core Structure Analysis
The product is compact and uses an industrial-grade modular design, with key components including:
RS485 Communication Interface (Terminal block): Electrically isolated design supporting up to 32 devices on the same bus.
RJ45 Ethernet Port: Features 2kV surge protection, ensuring stable communication.
Rail-mountable Enclosure: Adapts to standard industrial control cabinets, saving space.
Power Input Terminal: Supports 9-24V DC with reverse polarity protection.
Status LEDs: Indicate network connection status, serial data flow direction for easy troubleshooting.
Measurement & Communication Methods
The Nexisense ZLAN5143D Fully isolated serial port server offers various operating modes and flexible communication configurations, including:
Protocol Support: TCP Server (supports up to 30 clients), TCP Client (up to 7 target IPs), UDP/UDP multicast,Virtual Serial Port (VCOM) for Windows compatibility.
Serial Communication Configuration: Baud Rate: 1200~115200bps, Data Bits: 5~9, Parity: None/Odd/Even/Mark/Space, Flow Control: Hardware (RTS/CTS), Software (XON/XOFF).
Network Protocol Support: ARP, ICMP, DHCP, DNS, etc., enabling dynamic IP and domain server connections.
MQTT and Cloud Platform Compatibility
The Nexisense ZLAN5143D Fully isolated serial port server supports MQTT clientintegration for IoT applications, sending collected serial data to cloud platforms:
RS485 data is parsed into standard JSON format.
The data is automatically packaged into MQTT packets and supports QoS configurations and heartbeat mechanisms.
Supported Platforms: Alibaba Cloud IoT, Baidu CloudIoT Hub, China Mobile OneNet, and private MQTT servers (supports authentication and non-authentication).
Configuration & Remote Management
The Nexisense ZLAN5143D Fully isolated serial port server supports full web-based configuration and SDK development for easy deployment andremote management:
Web-based visual configurationof parameters (serial port settings, protocol modes, target IPs).
DHupgrades, and batch parameter deployment.
Remote monitoring of TCP connection status and serial data flow statistics.
Virtual Serial Port toolfor data monitoring and debugging.
