Primary function
bi-directional transparent data transmission between RS232 and Ethernet
Rail-mount support
easy to combine multi rail-mounted serial server together, more freely
Modbus gateway support
suitable for Modbus gridding upgrade, Can Be Used With Specific Configuration Software
Multi communication modes
supports TCP server / TCP client / UDP mode / UDP multicast
MQTT/JSON to Modbus
more flexible conversion between different protocols
When used as MQTT gateway, the devices can upload serial data to MQTT server by MQTT protocol through transparent transmission, supported servers including Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet, etc. The acquired Modbus RTU or non-standard serial data can be parsed into JSON format and packaged into MQTTdata packet for uploading.
When used as JSON data acquisition gateway, the devices can be connected to data acquisition instruments through RS232 connection, then acquire data automatically, convert the data into JSON format, and finally post it to server. The acquired data supports Modbus RTU 645 instrument 97 version, 645 instrument 07 version, as well as sorts of non-standard RS232 protocols. The uploaded data format can be configured via host, and the JSON upload protocol can be MQTT protocol, HTTP POST protocol, HTTP GET protocol, and so on.
Multi hosts roll-polling support
- different network devices will be identified and responded respectively, no more crosstalk issue while communicating with multi network devices
User-defined heartbeat/registration packet
- easy for cloud communication and device identification
NTP protocol support
- getting network time info for serial output or data upload
Multi configuration methods
- supports Web browser configuration, obtaining dynamic IP via DHCP, DNS protocol connected domain server address
