8 Port Serial Ethernet Server | Support SSL, MQTT, Modbus-RTU to Modbus-TCP

● It uses ARM 9 processor with a main frequency 300MHz, running Linux OS OpenWrt system.

● It supports 2 10/100M adaptive Ethernet interfaces, providing dual IP and dual MAC addresses to meet the requirements of multiple network management or network backup.

● Ethernet supports 10/100base-T adaptive and supports automatic negotiation (Auto-Nego Full&half duplex) and automatic crossover detection (MDI/MDIX).

● Serial port supports 300bps-150000bps line-speed non-blocking communication.

● The serial data port has 2 modes:

   1. Each port provides one of RS-232/RS-485/RS-485 interfaces, which can be configured arbitrarily at the factory.

   2. Each port provides all three types of RS-232/RS-485/RS-485 interfaces, which can be set to different interface modes in the field by DIP switch.

● It supports Modbus TCP, TCP Server, TCP Client, UDP Server, UDP Client, and other working modes.

● It completes transparent conversion from Modbus-RTU to Modbus-TCP, enabling serial device data to be read through the network.

● It supports SSL security protocol for serial data encryption transmission.

● It supports MQTT multiple topics subscription and publishing functions.

● It supports MQTT transparent transmission and Modbus-to-JSON data packet conversion, and supports parsing JSON issued by the server and timed reporting functions respectively.

● It supports MQTT protocol docking with various cloud platforms such as Huawei Cloud, and Alibaba Cloud.

● It supports serial port status and parameters monitoring, with communication status clear at a glance.

● It supports communication across gateways and routers, virtual serial port driver access mode, and network interruption automatic reconnection function.

● Flexible serial data framing settings to meet various packeting requirements of users.

● It supports standard TCP/IP SOCKET application program access, with support for multiple connections, meeting the requirements of up to 4 users simultaneously monitoring or managing serial devices.

● In UDP mode, the device supports communication between single or multiple devices, meeting the requirements of multiple users simultaneously monitoring or managing serial devices.

● It supports various configuration forms such as Windows configuration tool, SSH, Telnet, and WEB, and supports SNMP network management.

● It supports local and remote system firmware upgrades.

● It supports wide range 9-55V AC and DC power input, internal isolation, and redundant dual power input.

● The power supply supports overload protection and anti-reverse connection protection, and it meets the requirements of industrial electromagnetic compatibility level 4.

● Strong lightning protection function: lightning protection, high voltage induction resistance, surge protection, etc.; fanless and efficient heat dissipation, reducing repair time.

● Anodized aluminum alloy shell, IP40 protection level, capable of withstanding harsh environments; it can be mounted on a din rail or wall-mounted.

● Working temperature: -40℃~ +85℃.

● The device has passed the 100% burn-in test.
