● 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.
