BASIC FUNCTION
Bi-directional transparent data transmission between RS485 and Ethernet
SUPPORTS DIN-RAIL MOUNTING
Easily combine multiple serial servers DIN-rail mounted, more flexible
SUPPORTS MODBUS GATEWAY
Suitable for Modbus network upgrade, can be used with 3D configuration software
MULTIPLE COMMUNICATION MODES
Supports TCP server / TCP client / UDP / UDP multicast mode
MQTT/JSON TO MODBUS
More flexible conversion between different protocols
When used as an MQTT gateway, devices can upload serial data to the MQTT server through the MQTT protocol using transparent transmission. Supported servers include Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet, and others. The received Modbus RTU data or non-standard serial data can be parsed in JSON format and packaged into an MQTT data packet for upload.
When used as a JSON data acquisition gateway, devices can be connected to data acquisition instruments via an RS485 connection, then automatically acquire data, convert the data to JSON format, and finally send it to the server. The acquired data supports Modbus RTU 645 meter version 97, 645 meter version 07, as well as various non-standard RS485 protocols. The format of the uploaded data can be configured via the host, and the JSON upload protocol can be MQTT protocol, HTTP POST protocol, HTTP GET protocol, etc.
SUPPORTS MULTI-HOST POLLING
Different network devices will be identified and respond accordingly,
no more crosstalk problems when communicating with multiple network devices
CUSTOM HEARTBEAT/REGISTRATION PACKET
Easy for cloud communication and device identification
SUPPORTS NTP PROTOCOL
Obtaining network time information for serial output or data upload
MULTIPLE CONFIGURATION METHODS
Supports web browser configuration, dynamic IP address acquisition via DHCP,
DNS protocol to connect to the domain server address
