Overview This is a RS485 device data acquisitor / IoT gateway designed for industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, etc. The module features RS485 and Ethernet port(POE function is optional), uses screw terminals for power input. Rail-mount flame-retardant case design, small in size, easy to install. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring... Specifications (1) Primary Introduction Product Type: Serial server, Modbus Gateway, MQTT Gateway Basic Function: Bi-directional transparent data transmission between RS485 and Ethernet Communication interface : RS485 port x 1, Ethernet port x 1 Power supply : 9 ~ 24V DC screw terminal (2) Communication Ethernet: common network port,10 / 100M auto-negotiation RJ45 connector, 2 KV surge protection Serial port: RS485 (3) Serial specification Baudrate: 300 ~ 115200 bps Parity bit: none, odd, even, mark, space Data bit: 5 ~ 9 bits (4) 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 multicas (5) Environment requirement Operating temperature: -40? ~ 85? Storage temperature: -45? ~ 125? Humidity range: 5% ~ 95% relative humidity Dimensions : L x W x H--- 87x 36 x 59 mm Development Resource/Online Instruction: n9.cl/6fw8v Package Content RS485 TO POE ETH (B) x1Support Web browser configuration, support DHCP to obtain IP dynamically, and DNS protocol to connect domain name server address. Support cloud remote search for devices, the configuration of device parameters, and device program upgrades. Support remote viewing of the device's TCP connection status, and serial port data sending and receiving status through software. The virtual serial port supports the data monitoring function. Support custom heartbeat package and registration package function: It is convenient to communicate with the cloud and identify devices. It supports the function that password authentication is required to establish a connection through TCP to ensure connection security. It supports the function of data submission and delivery in HTTP mode, and the cloud can directly use the HTTP GET command to interact with the serial port data of the device. Support Modbus gateway function,suitable for Modbus gridding upgrade, can be used with 3D configuration software. Support Modbus RTU to Modbus TCP. It can support storage-type Modbus, and can automatically collect device data and store it; it also supports a non-storage mode Modbus gateway. Support JSON to Modbus RTU and 645-meter protocol, support HTTP POST, and HTTP GET format to upload data. Multi communication modes, supports TCP server / TCP client / UDP mode / UDP multicast. Multi hosts roll-polling support: different network devices will be identified and responsed respectively, no more crosstalk issue while communicating with multi network devices. Multi configuration methods: supports Web browser configuration, obtaining dynamic IP via DHCP,DNS protocol connected domain server address. RS485 to RJ45 Ethernet Module with POE Function, Bi-Directional Transparent Data Transmission Between RS485 and Ethernet. Rail-mount support, easy to combine multi rail-mounted serial server together, more freely.
