2-Ch RS485 To RJ45 Ethernet Serial Server, Dual Channels RS485 Independent Operation, Dual Ethernet Ports, Rail-Mount Industrial Isolated Serial Module, Bi-Directional Transparent Transmission
Specifications2-CH RS485 TO ETH (B) 2-CH RS485 TO POE ETH (B) 2-CH RS485 + Common network port + Electrical isolation 2-CH RS485 + PoE network port + Electrical isolation Product Type Serial server, Modbus Gateway, MQTT Gateway Basic Function Bi-directional transparent data transmission between RS485 and Ethernet Communication interface RS485 port × 2, Ethernet port × 2 Power supply DC 5.5 power port, 6 ~ 45V DC screw terminal DC 5.5 power port, 6 ~ 45V DC screw terminal, or PoE port Isolation Protection Power isolation, Signal isolation COMMUNICATION Ethernet RJ45 RJ45 with PoE support, IEEE 802.3af compliant 10 / 100M auto-negotiation RJ45 connector, 2 KV surge protection Serial port Isolated RS485 (the 2 channels can receive and transmit independently at the same time) SERIAL SPECIFICATION Baudrate 300 ~ 115200 bps Parity bit none, odd, even, mark, space Data bit 5 ~ 9 bits Flow control N/A SOFTWARE Protocol ETHERNET, IP, TCP, UDP, HTTP, ARP, ICMP, DHCP, DNS Configuration host, web browser, device management functions library Communication method TCP/IP direct communication, VCOM Operating mode TCP server, TCP client (coexisting with TCP server), UDP, UDP multicast ENVIRONMENT REQUIREMENT Operating temperature -40℃ ~ 85℃ Humidity range 5% ~ 95% relative humidity Dimensions L × W × H: 78.0 × 72.5 × 24.2 mm * Note: Each module in the cascade needs to be powered individually. If it is the POE version, it can be powered directly through the Ethernet cable. The working current of the module is 12V/150mA (MAX) and can be cascaded up to 8.MQTT/JSON To ModbusMore 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 RS485 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 RS485 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.
Multiple Protection, Safe And StableOnboard power supply and signal isolation, it can provide stable isolation voltage with high reliability and strong anti-interference. Built-in TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient peak voltage in the circuit, lightningproof & ESD protection. Built-in resettable fuse and protection diode to ensure stable output of current and voltage, prevents over-current and over-voltage proof, improve shock resistance
